    Heitner, Kerri A.

    Existing security policies in civil aviation do not adequately protect against evolving cyber threats. Cybersecurity has been recognized as a top priority among some aviation industry leaders. Heightened concerns regarding cyber threats and vulnerabilities surround components utilized in compliance with the Federal Aviation Administration's (FAA) Next Generation Air Transportation (NextGen) implementation. Automated Dependent Surveillance-B (ADS-B) and Electronic Flight Bags (EFB) have both been exploited through the research of experienced computer security professionals. Civil aviation is essential to international infrastructure and if its critical assets were compromised, it could pose a great risk to public safety and financial infrastructure. The purpose of this research was to raise awareness of aircraft system vulnerabilities in order to provoke change among current national and international cybersecurity policies, procedures and standards. Although the education of cyber threats is increasing in the aviation industry, there is not enough urgency when creating cybersecurity policies. This project intended to answer the following questions: What are the cyber threats to ADS-B of an aircraft in-flight? What are the cyber threats to EFB? What is the aviation industry's response to the issue of cybersecurity and in-flight safety? ADS-B remains unencrypted while the FAA's mandate to implement this system is rapidly approaching. The cyber threat of both portable and non-portable EFB's have received increased publicity, however, airlines are not responding quick enough (if at all) to create policies for the use of these devices. Collectively, the aviation industry is not being proactive enough to protect its aircraft or airport network systems. That is not to say there are not leaders in cybersecurity advancement. These proactive organizations must set the standard for the future to better protect society and it's most reliable form of transportation.

  9. Climate Change and International Civil Aviation Negotiations

    Directory of Open Access Journals (Sweden)

    Veronica Korber Gonçalves

    Full Text Available Abstract The International Civil Aviation Organization (ICAO has discussed ways of regulating greenhouse gas (GHG emissions by civil aircraft for almost 20 years. Over the past four years, a consensus has developed about a market-based mechanism in the form of a carbon offset system. This article describes the route to the agreement reached by ICAO’s 39th Assembly, in order to contextualise the results and point out some of its limitations. It points to two main factors that contributed to the consensus: the role of the European Union, which sought to lead the negotiations, and the choice of a flexible and ultimately weak mechanism that received support from the international airlines.

  10. Global civil aviation black carbon emissions.

    Science.gov (United States)

    Stettler, Marc E J; Boies, Adam M; Petzold, Andreas; Barrett, Steven R H

    2013-09-17

    Aircraft black carbon (BC) emissions contribute to climate forcing, but few estimates of BC emitted by aircraft at cruise exist. For the majority of aircraft engines the only BC-related measurement available is smoke number (SN)-a filter based optical method designed to measure near-ground plume visibility, not mass. While the first order approximation (FOA3) technique has been developed to estimate BC mass emissions normalized by fuel burn [EI(BC)] from SN, it is shown that it underestimates EI(BC) by >90% in 35% of directly measured cases (R(2) = -0.10). As there are no plans to measure BC emissions from all existing certified engines-which will be in service for several decades-it is necessary to estimate EI(BC) for existing aircraft on the ground and at cruise. An alternative method, called FOX, that is independent of the SN is developed to estimate BC emissions. Estimates of EI(BC) at ground level are significantly improved (R(2) = 0.68), whereas estimates at cruise are within 30% of measurements. Implementing this approach for global civil aviation estimated aircraft BC emissions are revised upward by a factor of ~3. Direct radiative forcing (RF) due to aviation BC emissions is estimated to be ~9.5 mW/m(2), equivalent to ~1/3 of the current RF due to aviation CO2 emissions.

    1994-01-01

    Clear air turbulence, wake vortices, dry hail, and volcanic ash are hazards to civil aviation that have not been brought to the forefront of public attention by a catastrophic accident. However, these four hazards are responsible for major and minor injuries, emotional trauma, significant aircraft damage, and in route and terminal area inefficiency. Most injuries occur during clear air turbulence. There is significant aircraft damage for any volcanic ash encounter. Rolls induced by wake vortices occur near the ground. Dry hail often appears as an area of weak echo on the weather radar. This paper will present the meteorological, electromagnetic, and spatiotemporal characteristics of each hazard. A description of a typical aircraft encounter with each hazard will be given. Analyzed microwave and millimeter wave sensor systems to detect each hazard will be presented.

  15. Evidence toward an expanded international civil aviation organization (ICAO) concept of a single unified global communication navigation surveillance air traffic management (CNS/ATM) system: A quantitative analysis of ADS-B technology within a CNS/ATM system

    Science.gov (United States)

    Gardner, Gregory S.

    This research dissertation summarizes research done on the topic of global air traffic control, to include technology, controlling world organizations and economic considerations. The International Civil Aviation Organization (ICAO) proposed communication, navigation, surveillance, air traffic management system (CNS/ATM) plan is the basis for the development of a single global CNS/ATM system concept as it is discussed within this study. Research will be evaluated on the efficacy of a single technology, Automatic Dependent Surveillance-Broadcast (ADS-B) within the scope of a single global CNS/ATM system concept. ADS-B has been used within the Federal Aviation Administration's (FAA) Capstone program for evaluation since the year 2000. The efficacy of ADS-B was measured solely by using National Transportation Safety Board (NTSB) data relating to accident and incident rates within the Alaskan airspace (AK) and that of the national airspace system (NAS).

    Aviation emissions impact surface air quality at multiple scales—from near-airport pollution peaks associated with airport landing and take off (LTO) emissions, to intercontinental pollution attributable to aircraft cruise emissions. Previous studies have quantified aviation’s air quality impacts around a specific airport, in a specific region, or at the global scale. However, no study has assessed the air quality and human health impacts of aviation, capturing effects on all aforementioned scales. This study uses a multi-scale modeling approach to quantify and monetize the air quality impact of civil aviation emissions, approximating effects of aircraft plume dynamics-related local dispersion (˜1 km), near-airport dispersion (˜10 km), regional (˜1000 km) and global (˜10 000 km) scale chemistry and transport. We use concentration-response functions to estimate premature deaths due to population exposure to aviation-attributable PM2.5 and ozone, finding that aviation emissions cause ˜16 000 (90% CI: 8300-24 000) premature deaths per year. Of these, LTO emissions contribute a quarter. Our estimate shows that premature deaths due to long-term exposure to aviation-attributable PM2.5 and O3 lead to costs of ˜21 bn per year. We compare these costs to other societal costs of aviation and find that they are on the same order of magnitude as global aviation-attributable climate costs, and one order of magnitude larger than aviation-attributable accident and noise costs.

  18. Louis H. Bauer and the origins of civil aviation medicine.

    Kraus, Theresa L

    2012-12-01

    With the passage of the Air Commerce Act in May 1926, civil aviation safety became a federal responsibility under the Department of Commerce (DoC). In November of that year, Louis Hopewell Bauer (1888-1964) became the DoC's first Aviation Medical Director. After earning his medical degree at the Harvard School of Medicine in 1912, Bauer joined the U.S. Army Medical Corps, where he helped develop the role of the military flight surgeon and then served as director of the Army's School of Aviation Medicine. Upon taking the federal position, he undertook to define medical standards and examination frequencies for civilian pilots and identifiy disqualifying conditions that could compromise a pilot's ability to operate an aircraft safely. Bauer also personally selected 57 private physicians (soon to be known as Aviation Medical Examiners) distributed across the country to give medical examinations for pilot licenses. Bauer subsequently played a leading role in organizing the Aviation Medical Association in 1929.

    2015-04-01

    Air pollutant emissions from aircraft have been subjected to less rigorous control than road traffic emissions, and the rapid growth of global aviation is a matter of concern in relation to human exposures to pollutants, and consequent effects upon health. Yim et al (2015 Environ. Res. Lett. 3 034001) estimate exposures globally arising from aircraft engine emissions of primary particulate matter, and from secondary sulphates and ozone, and use concentration-response functions to calculate the impact upon mortality, which is monetised using the value of statistical life. This study makes a valuable contribution to estimating the magnitude of public health impact at various scales, ranging from local, near airport, regional and global. The results highlight the need to implement future mitigation actions to limit impacts of aviation upon air quality and public health. The approach adopted in Yim et al only accounts for the air pollutants emitted by aircraft engine exhausts. Whilst aircraft emissions are often considered as dominant near runways, there are a number of other sources and processes related to aviation that still need to be accounted for. This includes impacts of nitrate aerosol formed from NOx emissions, but probably more important, are the other airport-related emissions from ground service equipment and road traffic. By inclusion of these, and consideration of non-fatal impacts, future research will generate comprehensive estimates of impact related to aviation and airports.

  1. Distributed Aviation Concepts and Technologies

    Moore, Mark D.

    2008-01-01

    Aviation has experienced one hundred years of evolution, resulting in the current air transportation system dominated by commercial airliners in a hub and spoke infrastructure. While the first fifty years involved disruptive technologies that required frequent vehicle adaptation, the second fifty years produced a stable evolutionary optimization of decreasing costs with increasing safety. This optimization has resulted in traits favoring a centralized service model with high vehicle productivity and cost efficiency. However, it may also have resulted in a system that is not sufficiently robust to withstand significant system disturbances. Aviation is currently facing rapid change from issues such as environmental damage, terrorism threat, congestion and capacity limitations, and cost of energy. Currently, these issues are leading to a loss of service for weaker spoke markets. These catalysts and a lack of robustness could result in a loss of service for much larger portions of the aviation market. The impact of other competing transportation services may be equally important as casual factors of change. Highway system forecasts indicate a dramatic slow down as congestion reaches a point of non-linearly increasing delay. In the next twenty-five years, there is the potential for aviation to transform itself into a more robust, scalable, adaptive, secure, safe, affordable, convenient, efficient and environmentally friendly system. To achieve these characteristics, the new system will likely be based on a distributed model that enables more direct services. Short range travel is already demonstrating itself to be inefficient with a centralized model, providing opportunities for emergent distributed services through air-taxi models. Technologies from the on-demand revolution in computers and communications are now available as major drivers for aviation on-demand adaptation. Other technologies such as electric propulsion are currently transforming the automobile

    Prevalence of tricyclic antidepressants (TCAs) has not been explored in pilots. The National Transportation Safety Board (NTSB) aviation accident and the Federal Aviation Administration's Civil Aerospace Medical Institute (CAMI) toxicology and medical certification databases were searched for pilots fatally injured in aviation accidents. During 1990-2012, CAMI received bio-samples of pilots from 7037 aviation accidents. Of these, 2644 cases were positive for drugs. TCAs were present in 31. TCA blood concentrations ranged from therapeutic to toxic levels. The NTSB determined that the use of drugs and ethanol as the probable cause or contributing factor in 35% (11 of 31) of the accidents. None of the 31 pilots reported the use of TCAs during their aviation medical examination. The prevalence of TCAs in aviators was less than 0.5% (31 of 7037 cases). There is a need for aviators to fully disclose the use of medications at the time of their medical examination. © 2016 American Academy of Forensic Sciences.

    2017-06-01

    Keratoconus is a progressive noninflammatory ectatic corneal dystrophy, characterized by corneal thinning and increased curvature with central or paracentral tapered protrusion. Such changes in corneal morphology induce irregular astigmatism and myopia, resulting in visual acuity impairment. This report assesses cases in which keratoconus is not an absolute disabling condition for civil aviation pilots. Six cases of keratoconus in active pilots are presented. This report includes cases which were treated with crosslinking therapy and even corneal transplantation. In such cases, the civil aviation medical authority considered four aspects in the medical assessment: best corrected visual acuity, condition stability, risk of sudden incapacitation, and pilot category. Six civil pilots with ages between 19 and 45 yr of age presented with keratoconus in different stages. Using the Snellen scale, best corrected visual acuity (BCVA) was measured in 12 eyes, all of them having equal or better than 20/30 (20/20, N = 9; 20/25, N = 2; 20/30, N = 1). All of them are currently fit for aviation activity and have been given an aviation medical certificate with limitation of use of corrective lenses by the Brazilian Civil Aviation Authority (ANAC in Portuguese). Among these cases, there is a pilot who had undergone treatment with crosslinking therapy and another that had undergone corneal transplantation. These cases demonstrate that keratoconus is not always a disabling condition for civil aviation pilots. Nevertheless, it has to be analyzed on a case-by-case basis.Rebello A, Rodrigues B, Pereira M.

    Full Text Available As a general rule the final step in every aviation program is the certification of the airplane, an important step in which the airplane, the engins and the equipments are checked by an authority or commission according to the airworthiness rules. The main scope of the certification is to promote a safe aviation product and to protect the general public from unnecessary risk. In all the contries the national authorieties require a civil certificability for all the parts or equipments and a full aircraft certification for a new or wholly modified airplane. The military aircrafts must pased and respond to a specific way of certification and many actual efforts are done in order to unify the diffrent national rules in this field. This paper presents the existing situation in the certification of civil and military airplans and the actual measures done for the unification of certification procedures in the world.

  17. Flying Wings. A New Paradigm for Civil Aviation?

    Directory of Open Access Journals (Sweden)

    R. Martinez-Val

    2007-01-01

    Full Text Available Over the last 50 years, commercial aviation has been mainly based what is currently called the conventional layout, characterized by a slender fuselage mated to a high aspect ratio wing, with aft-tail planes and pod-mounted engines under the wing. However, it seems that this primary configuration is approaching an asymptote in its productivity and performance characteristics. One of the most promising configurations for the future is the flying wing in its distinct arrangements: blended-wing-body, C-wing, tail-less aircraft, etc. These layouts might provide significant fuel savings and, hence, a decrease in pollution. This configuration would also reduce noise in take-off and landing. All this explains the great deal of activity carried out by the aircraft industry and by numerous investigators to perform feasibility and conceptual design studies of this aircraft layout to gain better knowledge of its main characteristics: productivity, airport compatibility, passenger acceptance, internal architecture, emergency evacuation, etc. The present paper discusses the main features of flying wings, their advantages over conventional competitors, and some key operational issues, such as evacuation and vortex wake intensity.

    2003-01-01

    Aviation deregulation is usually a challenging and demanding task and accession to the European Union requires that all candidate states should harmonize their legislation in the context of the European Common Aviation Area. Malta and Cyprus, the small Mediterranean island-states to join the EU in 2004, will have to abandon any protectionist policies in favour of their flag-carriers and let them survive in a liberal framework. The paper discusses the implications of this regime change for civil aviation in Malta and Cyprus and in addition to the airline industry, it examines the impacts on the complementary tourism sector. Unless carrying capacity limits are understood, the islands may become victims of successful airline liberalisation. The paper concludes by stressing the need for sustainable development and active policy making. Keywords: carrying capacity, Cyprus, air transport deregulation, Malta, tourism

    Full Text Available Aim. This study aimed to analyze blood lipid levels, temporal trend, and age distribution of dyslipidemia in civil aviators in China. Methods. The 305 Chinese aviators were selected randomly and followed up from 2006 to 2011. Their total cholesterol (TC, triglyceride (TG, high-density lipoprotein cholesterol (HDL-C, and low-density lipoprotein cholesterol (LDL-C levels were evaluated annually. Mean values for each parameter by year were compared using a linear mixed-effects model. The temporal trend of borderline high, high, and low status for each index and of overall borderline high, hyperlipidemia, and dyslipidemia by year was tested using a generalized linear mixed model. Results. The aviators' TC (F=4.33, P<0.01, HDL-C (F=23.25, P<0.01, and LDL-C (F=6.13, P<0.01 values differed across years. The prevalence of dyslipidemia (F=5.53, P<0.01, borderline high (F=6.52, P<0.01, and hyperlipidemia (F=3.90, P<0.01 also differed across years. The prevalence rates for hyperlipidemia and dyslipidemia were the highest in the 41–50-year-old and 31–40-year-old groups. Conclusions. Civil aviators in China were in high dyslipidemia and borderline high level and presented with dyslipidemia younger than other Chinese populations.

    Human factors become the most serious problem leading to accidents of civil aviation, which stimulates the design and analysis of Neuron Type Test (NTT) system to explore the intrinsic properties and patterns behind the behaviors of professionals and students in civil aviation. In the experiment, normal practitioners' reaction time sequences, collected from NTT, exhibit log-normal distribution approximately. We apply the χ2 test to compute the goodness-of-fit by transforming the time sequence with Box-Cox transformation to cluster practitioners. The long-term correlation of different individual practitioner's time sequence is represented by the Hurst exponent via Rescaled Range Analysis, also named by Range/Standard deviation (R/S) Analysis. The different Hurst exponent suggests the existence of different collective behavior and different intrinsic patterns of human factors in civil aviation.

  2. GENERALIZED LANDSCAPE THEORY: AGENT-BASED APPROACH TO ALLIANCE FORMATIONS IN CIVIL AVIATION INDUSTRY

    Institute of Scientific and Technical Information of China (English)

    Kyoichi Kijima

    2001-01-01

    The purpose of this paper is to generalize Landscape theory proposed by R.Axelrod and, then, to apply it to the civil aviation industry for simulating alliance formations in it. Landscape theory provides a well-known agent-based simulation model for analyzing alliance (or coalition) formation process. When a set N of agents or autonomous decision makers is given, the theory assumes that each agent tries to make a coalition in such a way that the resulting alliance minimizes its frustration. The theory is essentially based on two premises. One is that a propensity is symmetric,i.e., the propensity of agent i toward j is exactly the same as that of j toward i for anyagents i and j in N. The other is that the number of alliances is restricted to two, i.e., at any moment N is partitioned into two parties. Though the two basic premises underpin the theory and make the model simple and operational, they do not always reflect alliance formation processes in a realistic way. A generalized Landscape theory that this paper proposes removes them and allows asymmetric propensity and existence of alliances of any number. Since the premises are essential for the model, the generalization requires a drastic reconstruction of the whole idea of the theory. Finally, we analyze a real alliance formation process in the civil aviation industry.This analysis provides interesting insights about the industry as well as some validation of our generalized Landscape theory.

    Full Text Available Ceramic matrix composites (CMCs are being designed and developed for engine and exhaust components in commercial aviation, because they offer higher temperature capabilities, weight savings, and improved durability compared to metals. The United States Federal Aviation Administration (FAA issues and enforces regulations and minimum standards covering the safe manufacture, operation, and maintenance of civil aircraft. As new materials, these ceramic composite components will have to meet the certification regulations of the FAA for “airworthiness”. The FAA certification process is defined in the Federal Aviation Regulations (Title 14 of the Code of Federal Regulations, FAA policy statements, orders, advisory circulars, technical standard orders, and FAA airworthiness directives. These regulations and documents provide the fundamental requirements and guidelines for design, testing, manufacture, quality assurance, registration, operation, inspection, maintenance, and repair of aircraft systems and parts. For metallic parts in aircraft, the FAA certification and compliance process is well-established for type and airworthiness certification, using ASTM and SAE standards, the MMPDS data handbook, and FAA advisory circulars. In a similar manner for polymer matrix composites (PMC, the PMC industry and the FAA have jointly developed and are refining parallel guidelines for polymer matrix composites (PMCs, using guidance in FAA circulars and the CMH-17 PMC handbook. These documents discuss design methods and codes, material testing, property data development, life/durability assessment, production processes, QA procedures, inspection methods, operational limits, and repairs for PMCs. For ceramic composites, the FAA and the CMC and aerospace community are working together (primarily through the CMH-17 CMC handbook to define and codify key design, production, and regulatory issues that have to be addressed in the certification of CMC components in

    An increased awareness of the need for safety in medicine in general and in surgery in particular has prompted comparisons between the cockpit and the operating room. These comparisons seem to make sense but tend to be oversimplified. Attempts in healthcare to mimic programs that have been credited for the safety of commercial aviation have met with varying results. The risk here is that oversimplified application of an aviation model may result in the abandonment of good ideas in medicine. This paper describes in more depth the differences between medicine and commercial aviation: from the hiring process, through initial operating experience, recurrent training, and the management of emergencies. These programs add up to a cultural difference. Aviation assumes that personnel are subject to mistake making and that systems and culture need to be constructed to catch and mitigate error; medicine is still focused on the perfection of each individual's performance. The implications of these differences are explored.

    An attempt was made to identify social impacts, both beneficial and detrimental, which would or could flow from the introduction of advanced civil aviation systems. A broad range of social impact areas was investigated which included economic, environmental, political, sociological, psychological, legal, and urban/regional developmental factors. Data are arranged into two major parts. In the first part, a series of Major Policy Issues are identified and discussed which appear, on the basis of the social impact study, to merit serious consideration. The discussion of each "Issue' is presented both to explain its relevance and to raise considerations which will bear on its satisfactory resolution. The second part views the same overall body of information in a different manner: a series of "Findings' are pointed out from which more concrete guidance for R and D policy can be derived, and a set of "Candidate Basic Federal Undertakings' thus derived are presented.

  14. Landing on empty: estimating the benefits from reducing fuel uplift in US Civil Aviation

    2015-09-01

    Airlines and Air Navigation Service Providers are united in their goal to reduce fuel consumption. While changes to flight operations and technology investments are the focus of a number of studies, our study is among the first to investigate an untapped source of aviation fuel consumption: excess contingency fuel loading. Given the downside risk of fuel exhaustion of diverting to an alternate airport, airline dispatchers may load excess fuel onto an aircraft. Such conservatism comes at a cost of consuming excess fuel, as fuel consumed is a function of, among other factors, aircraft weight. The aim of this paper is to quantify, on a per-flight basis, the fuel burned due to carrying fuel beyond what is needed for foreseeable contingencies, and thereby motivate research, federal guidance, and investments that allow airline dispatchers to reduce fuel uplift while maintaining near zero risks of fuel exhaustion. We merge large publicly available aviation and weather databases with a detailed dataset from a major US airline. Upon estimating factors that capture the quantity fuel consumed due to carrying a pound of weight for a range of aircraft types, we calculate the cost and greenhouse gas emissions from carrying unused fuel on arrival and additional contingency fuel above a conservative buffer for foreseeable contingencies. We establish that the major US carrier does indeed load fuel conservatively. We find that 4.48% of the fuel consumed by an average flight is due to carrying unused fuel and 1.04% of the fuel consumed by an average flight is due to carrying additional contingency fuel above a reasonable buffer. We find that simple changes in flight dispatching that maintain a statistically minimal risk of fuel exhaustion could result in yearly savings of 338 million lbs of CO2, the equivalent to the fuel consumed from 4760 flights on midsized commercial aircraft. Moreover, policy changes regarding maximum fuel loads or investments that reduce uncertainty or increase

  1. Integrating human factors knowledge into certification: The point of view of the Internatioanal Civil Aviation Organization (ICAO)

    Maurino, Daniel; Galotti, Vincent

    1994-01-01

    It is appropriate here to repeat the analogy described in the introduction to this paper which is that: The consideration of human factors requirements during the design stage of advanced, new technology systems may be seen as resting over a three-legged stool. The first leg, the equipment that a system will utilize to achieve its goals, has traditionally attracted ergonomic considerations associated with equipment design, usually centered around 'knobs and dials.' Lately, this view has expanded to include the so-called other important aspect of Human Factor's study which deals with the cognitive, behaviorial and social processes of the human operators. Study in this area must be furthered. The second leg of the stool, the procedures to operate the equipment, however, has been largely unaddressed. Procedures are not inherent to equipment, but must be developed. The importance of proper human factors consideration in the design of procedures can not be overstated. Lastly, the third leg of the stool, the certification of personnel who will operate the equipment, is very much underway, but far from being complete. The real quest now, however, is to integrate these three legs into an indivisible one. Finally, and most importantly, this workshop and its topic are extremely timely in that we are at the dawn of the most ambitious development ever undertaken in international civil aviation. This would allow us the rather unique opportunity to put theory into practice in the near future by ensuring that the concepts developed and furthered by this workshop and the follow-up are implemented in the design and certification of the ICAO future CNS/ATM systems described earlier in this paper. Now is the time to incorporate human factors requirements during the certification processes of these systems. This might act as a test to the feasibility of these ideas. Such endeavors represent a challenge for the research, engineering, training, operational and regulatory communities

    General aviation accounted for 74 percent of runway incursions but only 57 percent of the operations during the four-year period from fiscal year (FY) 2001 through FY2004. Elements of the NASA Runway Incursion Prevention System were adapted and tested for general aviation aircraft. Sixteen General Aviation pilots, of varying levels of certification and amount of experience, participated in a piloted simulation study to evaluate the system for prevention of general aviation runway incursions compared to existing moving map displays. Pilots flew numerous complex, high workload approaches under varying weather and visibility conditions. A rare-event runway incursion scenario was presented, unbeknownst to the pilots, which represented a typical runway incursion situation. The results validated the efficacy and safety need for a runway incursion prevention system for general aviation aircraft.

    For more than a century, important civil engineering structures such as bridges, high-rise buildings, dams and marine platforms have contained iron or steel as the reinforcement for concrete or wood (ISIS Canada Strategic Plan, 2000). The useful lives of such structures have often been severely limited by the corrosion of this ferrous component. Much thought has been given in recent years to constructing structures that are lighter, stronger and non-corrosive. These innovative structures are new and for these to be accepted by the engineering community monitoring is mandatory. ISIS Canada has been developing such structures and monitoring them. In this paper, innovative bridge decks that have been implemented is described.

    2012-01-01

    The concern for reducing aviation safety risk is rising as the National Airspace System in the United States transforms to the Next Generation Air Transportation System (NextGen). The NASA Aviation Safety Program is committed to developing an effective aviation safety technology portfolio to meet the challenges of this transformation and to mitigate relevant safety risks. The paper focuses on the reasoning of selecting Object-Oriented Bayesian Networks (OOBN) as the technique and commercial software for the accident modeling and portfolio assessment. To illustrate the benefits of OOBN in a large and complex aviation accident model, the in-flight Loss-of-Control Accident Framework (LOCAF) constructed as an influence diagram is presented. An OOBN approach not only simplifies construction and maintenance of complex causal networks for the modelers, but also offers a well-organized hierarchical network that is easier for decision makers to exploit the model examining the effectiveness of risk mitigation strategies through technology insertions.

    2006-01-01

    The NASA Heavy Lift Rotorcraft Systems Investigation examined in depth several rotorcraft configurations for large civil transport, designed to meet the technology goals of the NASA Vehicle Systems Program. The investigation identified the Large Civil Tiltrotor as the configuration with the best potential to meet the technology goals. The design presented was economically competitive, with the potential for substantial impact on the air transportation system. The keys to achieving a competitive aircraft were low drag airframe and low disk loading rotors; structural weight reduction, for both airframe and rotors; drive system weight reduction; improved engine efficiency; low maintenance design; and manufacturing cost comparable to fixed-wing aircraft. Risk reduction plans were developed to provide the strategic direction to support a heavy-lift rotorcraft development. The following high risk areas were identified for heavy lift rotorcraft: high torque, light weight drive system; high performance, structurally efficient rotor/wing system; low noise aircraft; and super-integrated vehicle management system.

    Buckner, Steven A.

    The Helicopter Emergency Medical Service (HEMS) industry has a significant role in the transportation of injured patients, but has experienced more accidents than all other segments of the aviation industry combined. With the objective of addressing this discrepancy, this study assesses the effect of safety management systems implementation and aviation technologies utilization on the reduction of HEMS accident rates. Participating were 147 pilots from Federal Aviation Regulations Part 135 HEMS operators, who completed a survey questionnaire based on the Safety Culture and Safety Management System Survey (SCSMSS). The study assessed the predictor value of SMS implementation and aviation technologies to the frequency of HEMS accident rates with correlation and multiple linear regression. The correlation analysis identified three significant positive relationships. HEMS years of experience had a high significant positive relationship with accident rate (r=.90; pNVG) (r=.38; pNVG, TAWS, and SMS, HEMS years of experience explained 81.4% of the variance in accident rate scores (p<.05), and HEMS years of experience was found to be a significant predictor of accident rates (p<.05). Additional quantitative regression analysis was recommended to replicate the results of this study and to consider the influence of these variables for continued reduction of HEMS accidents, and to induce execution of SMS and aviation technologies from a systems engineering application. Recommendations for practice included the adoption of existing regulatory guidance for a SMS program. A qualitative analysis was also recommended for future study SMS implementation and HEMS accident rate from the pilot's perspective. A quantitative longitudinal study would further explore inferential relationships between the study variables. Current strategies should include the increased utilization of available aviation technology resources as this proactive stance may be beneficial for the establishment of

    . We present probabilistic hazard maps and discuss their implications for Mexican civil aviation at regional scale. Results show that Benito Juarez and Puebla international airports have a substantial probability of being disrupted by the eruptive scenario modeled. Moreover, the National and International air traffic may suffer reductions and several strategical airports such as Toluca, Ciudad del Carmen and Queretaro may suffer strong disruptions. Results of tephra dispersal hazard assessment complement the existing multi-hazard assessment of Popocatepetl volcano. Hazard maps of tephra dispersal at relevant flying level are particularly important for long-term risk management of Mexican air traffic network.

    1999-03-01

    The European Union's Basic Safety Standards Directive (96/29/Euratom) lays down safety standards for the protection of workers and the general public against the effects of ionising radiations. Article 42 of the Directive deals with the protection of aircrew. It states that for crew of jet aircraft who are likely to be subject to exposure to more than 1 mSv y-1 appropriate measures must be taken, in particular: to assess the exposure of the crew concerned, to take into account the assessed exposure when organising working schedules with a view to reducing the doses of highly exposed aircrew, to inform concerned workers of the health risks involved in their work, to apply Article 10 to female aircrew. (The unborn child shall be treated like a member of the public.) This Directive must be transformed into national law of the 15 member states of the European Union by 13 May 2000. The European Commission and the Radiological Protection Institute of Ireland sponsored this International Conference. The objective of this conference was to assist both the airline industry and the national regulatory organisations in identifying the means available to comply with the requirements of the Directive. Over 200 delegates attended the conference from more than 25 countries. The welcoming addresses were made by Mary Upton (Director of the Radiological Protection Institute of Ireland), Joe Jacob (Minister for State responsible for Nuclear Safety) and James Currie (Director-General for the Environment, Nuclear Safety and Civil Protection). Mr Currie stated that there was a need for political decisions to be based on good science, and that technological trends will lead to higher and longer flights, and therefore higher radiation doses. The first day concentrated on the scientific basis of measurement, calculation and monitoring of cosmic radiation. The first speaker, Dr Heinrich from the University of Siegen, Germany, talked about the physics of cosmic radiation fields. He pointed

    2011-09-01

    The past oil crises have caused dramatic improvements in fuel efficiency in all industrial sectors. The aviation sector-aircraft manufacturers and airlines-has also made significant efforts to improve the fuel efficiency through more advanced jet engines, high-lift wing designs, and lighter airframe materials. However, the innovations in energy-saving aircraft technologies do not coincide with the oil crisis periods. The largest improvement in aircraft fuel efficiency took place in the 1960s while the high oil prices in the 1970s and on did not induce manufacturers or airlines to achieve a faster rate of innovation. In this paper, we employ a historical analysis to examine the socio-economic reasons behind the relatively slow technological innovation in aircraft fuel efficiency over the last 40 years. Based on the industry and passenger behaviors studied and prospects for alternative fuel options, this paper offers insights for the aviation sector to shift toward more sustainable technological options in the medium term. Second-generation biofuels could be the feasible option with a meaningful reduction in aviation's lifecycle environmental impact if they can achieve sufficient economies of scale.

    This is the final report of a two-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The objective was to determine whether armor tile technology could be used to solve problems of civil law enforcement as identified by the New Mexico State Police. Most of the effort focused on the design and construction of a lightweight, portable box that could contain the shrapnel and redirect the blast from a steel-pipe/black-powder bomb. The bomb box task was carried out in collaboration with two companies, Foster Miller, Inc. and Ordnance Body Armor Co., who constructed most of the boxes tested. The results of the tests indicated that soft, flexible fabrics are superior to hard tiles in containing the bomb fragments. Subsequent to these experiments, Foster Miller has developed a bomb container that is commercialized and is currently being sold to law enforcement agencies.

    2012-11-01

    Long-range dispersal of volcanic ash can disrupt civil aviation over large areas, as occurred during the 2010 eruption of Eyjafjallajökull volcano in Iceland. Here we assess the hazard for civil aviation posed by volcanic ash from a potential violent Strombolian eruption of Somma-Vesuvius, the most likely scenario if eruptive activity resumed at this volcano. A Somma-Vesuvius eruption is of concern for two main reasons: (1) there is a high probability (38 %) that the eruption will be violent Strombolian, as this activity has been common in the most recent period of activity (between AD 1631 and 1944); and (2) violent Strombolian eruptions typically last longer than higher-magnitude events (from 3 to 7 days for the climactic phases) and, consequently, are likely to cause prolonged air traffic disruption (even at large distances if a substantial amount of fine ash is produced such as is typical during Vesuvius eruptions). We compute probabilistic hazard maps for airborne ash concentration at relevant flight levels using the FALL3D ash dispersal model and a statistically representative set of meteorological conditions. Probabilistic hazard maps are computed for two different ash concentration thresholds, 2 and 0.2 mg/m3, which correspond, respectively, to the no-fly and enhanced procedure conditions defined in Europe during the Eyjafjallajökull eruption. The seasonal influence of ash dispersal is also analysed by computing seasonal maps. We define the persistence of ash in the atmosphere as the time that a concentration threshold is exceeded divided by the total duration of the eruption (here the eruption phase producing a sustained eruption column). The maps of averaged persistence give additional information on the expected duration of the conditions leading to flight disruption at a given location. We assess the impact that a violent Strombolian eruption would have on the main airports and aerial corridors of the Central Mediterranean area, and this assessment

    Full Text Available The past oil crises have caused dramatic improvements in fuel efficiency in all industrial sectors. The aviation sector—aircraft manufacturers and airlines—has also made significant efforts to improve the fuel efficiency through more advanced jet engines, high-lift wing designs, and lighter airframe materials. However, the innovations in energy-saving aircraft technologies do not coincide with the oil crisis periods. The largest improvement in aircraft fuel efficiency took place in the 1960s while the high oil prices in the 1970s and on did not induce manufacturers or airlines to achieve a faster rate of innovation. In this paper, we employ a historical analysis to examine the socio-economic reasons behind the relatively slow technological innovation in aircraft fuel efficiency over the last 40 years. Based on the industry and passenger behaviors studied and prospects for alternative fuel options, this paper offers insights for the aviation sector to shift toward more sustainable technological options in the medium term. Second-generation biofuels could be the feasible option with a meaningful reduction in aviation’s lifecycle environmental impact if they can achieve sufficient economies of scale.

    2008-01-01

    This article proposes a precise and ecofriendly micromachining technology for aerospace application called electrochemical machining in pure water (PW-ECM). On the basis of the principles of water dissociation, a series of test setups and tests are devised and performed under different conditions. These tests explain the need for technological conditions realizing PW-ECM, and further explore the technological principles. The results from the tests demonstrate a successful removal of electrolytic slime by means of ultrasonic vibration of the workpiece. To ensure the stability and reliability of PW-ECM process, a new combined rnachining method of PW-ECM assisted with ultrasonic vibration (PW-ECM/USV) is devised. Trilateral and square cavities and holes as well as a group of English alphabets are worked out on a stainless steel plate. It is eonfirmed that PW-ECM will be probably an efficient new aviation precision machining method.

    Popocatépetl is one of Mexico’s most active volcanoes threatening a densely populated area that includes Mexico City with more than 20 million inhabitants. The destructive potential of this volcano is demonstrated by its Late Pleistocene–Holocene eruptive activity, which has been characterized by recurrent Plinian eruptions of large magnitude, the last two of which destroyed human settlements in pre-Hispanic times. Popocatépetl’s reawakening in 1994 produced a crisis that culminated with the evacuation of two villages on the northeastern flank of the volcano. Shortly after, a monitoring system and a civil protection contingency plan based on a hazard zone map were implemented. The current volcanic hazards map considers the potential occurrence of different volcanic phenomena, including pyroclastic density currents and lahars. However, no quantitative assessment of the tephra hazard, especially related to atmospheric dispersal, has been performed. The presence of airborne volcanic ash at low and jet-cruise atmospheric levels compromises the safety of aircraft operations and forces re-routing of aircraft to prevent encounters with volcanic ash clouds. Given the high number of important airports in the surroundings of Popocatépetl volcano and considering the potential threat posed to civil aviation in Mexico and adjacent regions in case of a Plinian eruption, a hazard assessment for tephra dispersal is required. In this work, we present the first probabilistic tephra dispersal hazard assessment for Popocatépetl volcano. We compute probabilistic hazard maps for critical thresholds of airborne ash concentrations at different flight levels, corresponding to the situation defined in Europe during 2010, and still under discussion. Tephra dispersal mode is performed using the FALL3D numerical model. Probabilistic hazard maps are built for a Plinian eruptive scenario defined on the basis of geological field data for the “Ochre Pumice” Plinian eruption (4965 14C

    近20 a来,中国航空运输业与旅游业均呈快速发展趋势,对两者关系的研究逐渐兴起。基于1985年以来中国航空旅客吞吐量和旅游人数的历史数据,采用面板VAR模型从全国和省域尺度定量分析了航空运输业与旅游业发展的关系。研究结果表明:中国航空运输业与旅游业的发展水平呈现出显著的时空相关性;在全国尺度上,两者发展呈现出长期均衡的关系,且航空运输业对旅游业发展的贡献率大于旅游业对航空运输业的贡献率;在省域尺度上,根据航空运输业与旅游业发展水平的相对关系,可将省份划分为高-高协调型、高-低磨合型、低-高磨合型、低-低协调型4种类型。%Since the civil aviation and tourism experienced a rapid development in China in the past two de-cades, the relationship between them has become a hot topic. Thispaper tries to explore the relationship be-tween civil aviation and tourism at both national and provincial scalebased onthe data of airport passenger throughput and tourist arrivals since 1985 using PVAR method. Results indicate that:1) China’s civil aviation and tourism show a significant positive relationship in both the temporal and spatial perspectives. Both of them have experienced 4 stages which are slow growth stage-slowly steady growth stage-fast steady growth stage and fast fluctuant growth stage. Spatially, airport passenger throughput and tourist arrivals show significant cor-relation, while the space correlation between airport passenger throughput and A-grade scenic spot show geo-graphic differences. 2) At national scale, the civil aviation and tourism present a long-term equilibrium devel-opment. The growth of civil aviation and tourism show similar reflect when another is facing shock, which is reducing at the beginning and then increasing. The result of variance demonstrates that the development of civ-il aviation has larger impacts on tourism

    The aim of this work was to examine how harsh luminous conditions in a cockpit, such as lightning in a thunderstorm or direct sunlight immediately after an aircraft passes through clouds, may affect the visual performance of pilots, and how to improve it. Such lighting conditions can result in the temporary visual impairment of aviators, which may greatly increase the risk of accidents. Tests were carried out in a full-scale simulator cockpit in which two kinds of dynamic lighting scenes, namely pulse changed and step changed lighting, were used to represent harsh luminous conditions. Visual acuity (VA), reaction time (RT) and identification accuracy (IA) were recorded as dependent variables. Data analysis results indicate that standardized VA values decreased significantly in both pulsing and step conditions in comparison with the dark condition. Standardized RT values increased significantly in the step condition; on the contrary, less reaction time was observed in the pulsing condition. Such effects could be reduced by an ambient illumination provided by a fluorescent lamp in both conditions. The results are to be used as a principle for optimizing lighting design with a thunderstorm light.

    General aviation includes all civilian aviation apart from operations involving paid passenger transport. Unfortunately, this category of aviation holds a lackluster safety record, accounting for 94% of civil aviation fatalities. In 2014, of 1143 general aviation accidents, 20% were fatal compared with 0 of 29 airline mishaps in the United States. Herein, research findings over the past 30 yr will be reviewed. Accident risk factors (e.g., adverse weather, geographical region, post-impact fire, gender differences) will be discussed. The review will also summarize the development and implementation of stringent crashworthiness designs with multi-axis dynamic testing and head-injury protection and its impact on mitigating occupant injury severity. The benefits and drawbacks of new technology and human factor considerations associated with increased general aviation automation will be debated. Data on the safety of the aging general aviation population and increased drug usage will also be described. Finally, areas in which general aviation occupant survival could be improved and injury severity mitigated will be discussed with the view of equipping aircraft with 1) crash-resistant fuel tanks to reduce post-impact conflagration; 2) after-market ballistic parachutes for older aircraft; and 3) current generation electronic locator beacons to hasten site access by first responders.Boyd DD.

  1. A methodology to enable rapid evaluation of aviation environmental impacts and aircraft technologies

    Science.gov (United States)

    Becker, Keith Frederick

    Commercial aviation has become an integral part of modern society and enables unprecedented global connectivity by increasing rapid business, cultural, and personal connectivity. In the decades following World War II, passenger travel through commercial aviation quickly grew at a rate of roughly 8% per year globally. The FAA's most recent Terminal Area Forecast predicts growth to continue at a rate of 2.5% domestically, and the market outlooks produced by Airbus and Boeing generally predict growth to continue at a rate of 5% per year globally over the next several decades, which translates into a need for up to 30,000 new aircraft produced by 2025. With such large numbers of new aircraft potentially entering service, any negative consequences of commercial aviation must undergo examination and mitigation by governing bodies so that growth may still be achieved. Options to simultaneously grow while reducing environmental impact include evolution of the commercial fleet through changes in operations, aircraft mix, and technology adoption. Methods to rapidly evaluate fleet environmental metrics are needed to enable decision makers to quickly compare the impact of different scenarios and weigh the impact of multiple policy options. As the fleet evolves, interdependencies may emerge in the form of tradeoffs between improvements in different environmental metrics as new technologies are brought into service. In order to include the impacts of these interdependencies on fleet evolution, physics-based modeling is required at the appropriate level of fidelity. Evaluation of environmental metrics in a physics-based manner can be done at the individual aircraft level, but will then not capture aggregate fleet metrics. Contrastingly, evaluation of environmental metrics at the fleet level is already being done for aircraft in the commercial fleet, but current tools and approaches require enhancement because they currently capture technology implementation through post

    为研究民航运输产业的竞争演化,考虑航空公司的资源竞争力、职能竞争力、核心竞争力及动态核心能力四层次竞争力等因素,建立了元胞自动机模型.以中美两国民航运输产业的竞争演化为例,对主导元胞(航空公司)和支持元胞(机场)的协同发展及其盈利状况进行了模拟研究.研究结果表明,美国民航业放松航空管制后因航空公司动态核心能力不强,行业整体盈利状况不佳;我国民航业半放松管制后,盈利状况也不容乐观.然而,提高航空公司的动态核心能力既可以避免美国民航业发展中经营惨淡的局面,同时又能促进我国民航业的快速发展.%In order to research the competition evolution of the aviation industry, built the cellular automata model with consideration of resource, function, core competence and dynamic core competence of airlines four competition factors. Took competition evolution of the civil aviation industry in China and USA for examples, simulated the coordinated development and profit status of the major cells (airlines) and supportive cells (airports). The result indicates the industry profit status of USA are not good after the deregulation because airlines do not have enough dynamic core competence, the industry profit status of China also are not good after the half-deregulation. However, improving the dynamic core competence of airlines could prevent the civil aviation industry from the loss of USA development example, meanwhile, could promote rapidly development of our country's civil aviation industry, too.

    2014-02-01

    Full Text Available Civilian and military participants in relief and stability operations rely upon Information and Communications Technology (ICT to collect, analyze, store, display, and share information that is critical for these civil-military interactions. This article investigates ICT innovation in these operations over time. As researchers in the sociology of technology school might predict, ICT innovation for relief and stability operations emerges in a distributed fashion, within clusters of specialty expertise that migrate across interconnected technology systems and across humanitarian and military activities. Major events such as natural disasters have punctuated the development of ICT for civil-military interactions, often driving community learning and coherence. Among the many stakeholders in the United States, the federal government in particular has played an important role in shaping the ICT ecosystem through policies and engagements. Government policies and changes in the field of action in the 1990s created imperatives for the US military in particular to collaborate with civilian agencies on ICT innovation. Civil-military information sharing gaps persist today due, in part, to institutional factors.

    Full Text Available Structural Health Monitoring (SHM aims to develop automated systems for the continuous monitoring, inspection, and damage detection of structures with minimum labour involvement. The first step to set up a SHM system is to incorporate a level of structural sensing capability that is reliable and possesses long term stability. Smart sensing technologies including the applications of fibre optic sensors, piezoelectric sensors, magnetostrictive sensors and self-diagnosing fibre reinforced composites, possess very important capabilities of monitoring various physical or chemical parameters related to the health and therefore, durable service life of structures. In particular, piezoelectric sensors and magnetorestrictive sensors can serve as both sensors and actuators, which make SHM to be an active monitoring system. Thus, smart sensing technologies are now currently available, and can be utilized to the SHM of civil engineering structures. In this paper, the application of smart materials/sensors for the SHM of civil engineering structures is critically reviewed. The major focus is on the evaluations of laboratory and field studies of smart materials/sensors in civil engineering structures.

    2014-01-01

    A Large Civil Tiltrotor (LCTR) conceptual design was developed as part of the NASA Heavy Lift Rotorcraft Systems Investigation in order to establish a consistent basis for evaluating the benefits of advanced technology for large tiltrotors. The concept has since evolved into the second-generation LCTR2, designed to carry 90 passengers for 1,000 nautical miles at 300 knots, with vertical takeoff and landing capability. This paper explores gas turbine component performance and cycle parameters to quantify performance gains possible for additional improvements in component and material performance beyond those identified in previous LCTR2 propulsion studies and to identify additional research areas. The vehicle-level characteristics from this advanced technology generation 2 propulsion architecture will help set performance levels as additional propulsion and power systems are conceived to meet ever-increasing requirements for mobility and comfort, while reducing energy use, cost, noise and emissions. The Large Civil Tiltrotor vehicle and mission will be discussed as a starting point for this effort. A few, relevant engine and component technology studies, including previous LCTR2 engine study results will be summarized to help orient the reader on gas turbine engine architecture, performance and limitations. Study assumptions and methodology used to explore engine design and performance, as well as assess vehicle sizing and mission performance will then be discussed. Individual performance for present and advanced engines, as well as engine performance effects on overall vehicle size and mission fuel usage, will be given. All results will be summarized to facilitate understanding the importance and interaction of various component and system performance on overall vehicle characteristics.

  10. Preliminary Assessment of Variable Speed Power Turbine Technology on Civil Tiltrotor Size and Performance

    Science.gov (United States)

    Snyder, Christopher A.; Acree, Cecil W., Jr.

    2012-01-01

    A Large Civil Tiltrotor (LCTR) conceptual design was developed as part of the NASA Heavy Lift Rotorcraft Systems Investigation in order to establish a consistent basis for evaluating the benefits of advanced technology for large tiltrotors. The concept has since evolved into the second-generation LCTR2, designed to carry 90 passengers for 1,000 nm at 300 knots, with vertical takeoff and landing capability. This paper performs a preliminary assessment of variable-speed power turbine technology on LCTR2 sizing, while maintaining the same, advanced technology engine core. Six concepts were studied; an advanced, single-speed engine with a conventional power turbine layout (Advanced Conventional Engine, or ACE) using a multi-speed (shifting) gearbox. There were five variable-speed power turbine (VSPT) engine concepts, comprising a matrix of either three or four turbine stages, and fixed or variable guide vanes; plus a minimum weight, twostage, fixed-geometry VSPT. The ACE is the lightest engine, but requires a multi-speed (shifting) gearbox to maximize its fuel efficiency, whereas the VSPT concepts use a lighter, fixed-ratio gearbox. The NASA Design and Analysis of Rotorcraft (NDARC) design code was used to study the trades between rotor and engine efficiency and weight. Rotor performance was determined by Comprehensive Analytical Model of Rotorcraft Aerodynamics and Dynamics (CAMRAD II), and engine performance was estimated with the Numerical Propulsion System Simulation (NPSS). Design trades for the ACE vs. VSPT are presented in terms of vehicle gross and empty weight, propulsion system weight and mission fuel burn for the civil mission. Because of its strong effect on gearbox weight and on both rotor and engine efficiency, rotor speed was chosen as the reference design variable for comparing design trades. Major study assumptions are presented and discussed. Impressive engine power-to-weight and fuel efficiency reduced vehicle sensitivity to propulsion system choice

    2011-07-01

    If fuel cell systems are to be used as fuel in civilian aircraft, sufficient storage volumes must be available. Apart from safety and cost, low weight is one of the key requirements. The system weight of cryogenic liquid hydrogen stores depends, among others, on the pressures inside the store as these will directly affect the pressure vessel wall thickness. The liquid hydrogen store supplies the fuel cell with hydrogen at a defined pre-pressure. This is not the design-relevant maximum possible pressure, which is limited by relief and safety valves. The pressure levels in the system are composed of different fractions, e.g. pressure losses and pressure fluctuations in the system, as well as the safety factors for the safety valves. The maximum pressure should be kept as low as possible in order to minimize the system weight. The relief and safety valves are differential pressure valves that open at a defined pressure relative to ambient pressure. In aviation, there is the problem that the ambient pressure varies between about 1,02 bar(a) on the ground and 0.18 bar(a) in flight. If systems are designed as for ground applications, there is the problem that the required hydrogen pressure cannot be maintained in flight as the relief valves will open already at lower pressures. To prevent this, the permissible pressure levels and safety factor must be defined for in-flight applications. The contribution describes the proposed liquid hydrogen storage concept for in-flight applications and develops a definition for defining pressure levels and safety factors for cryogenic liquid hydrogen stores in aviation in consideration of the pertinent standards and technical rules.

    2001-01-01

    Ground and airborne technologies were developed in the Terminal Area Productivity (TAP) project for increasing throughput at major airports by safely maintaining good-weather operating capacity during bad weather. Methods were demonstrated for accurately predicting vortices to prevent wake-turbulence encounters and to reduce in-trail separation requirements for aircraft approaching the same runway for landing. Technology was demonstrated that safely enabled independent simultaneous approaches in poor weather conditions to parallel runways spaced less than 3,400 ft apart. Guidance, control, and situation-awareness systems were developed to reduce congestion in airport surface operations resulting from the increased throughput, particularly during night and instrument meteorological conditions (IMC). These systems decreased runway occupancy time by safely and smoothly decelerating the aircraft, increasing taxi speed, and safely steering the aircraft off the runway. Simulations were performed in which optimal trajectories were determined by air traffic control (ATC) and communicated to flight crews by means of Center TRACON Automation System/Flight Management System (CTASFMS) automation to reduce flight delays, increase throughput, and ensure flight safety.

    Mavris, Dimitri N.; Tai, Jimmy C.; Kirby, Michelle M.; Roth, Bryce A.

    1999-01-01

    The primary aspiration of this study was to objectively assess the feasibility of the application of a low speed pneumatic technology, in particular Circulation Control (CC) to an HSCT concept. Circulation Control has been chosen as an enabling technology to be applied on a generic High Speed Civil Transport (HSCT). This technology has been proven for various subsonic vehicles including flight tests on a Navy A-6 and computational application on a Boeing 737. Yet, CC has not been widely accepted for general commercial fixed-wing use but its potential has been extensively investigated for decades in wind tunnels across the globe for application to rotorcraft. More recently, an experimental investigation was performed at Georgia Tech Research Institute (GTRI) with application to an HSCT-type configuration. The data from those experiments was to be applied to a full-scale vehicle to assess the impact from a system level point of view. Hence, this study attempted to quantitatively assess the impact of this technology to an HSCT. The study objective was achieved in three primary steps: 1) Defining the need for CC technology; 2) Wind tunnel data reduction; 3) Detailed takeoff/landing performance assessment. Defining the need for the CC technology application to an HSCT encompassed a preliminary system level analysis. This was accomplished through the utilization of recent developments in modern aircraft design theory at Aerospace Systems Design Laboratory (ASDL). These developments include the creation of techniques and methods needed for the identification of technical feasibility show stoppers. These techniques and methods allow the designer to rapidly assess a design space and disciplinary metric enhancements to enlarge or improve the design space. The takeoff and landing field lengths were identified as the concept "show-stoppers". Once the need for CC was established, the actual application of data and trends was assessed. This assessment entailed a reduction of the

    With the rapid development of international civil aviation transport industry , the number of cases where un-ruly passengers on board of aircrafts also showed a surge trend .Practicing these cases only in accordance with the 1963 Convention on Offences and Certain Other Acts Committed on Board Aircraft ( Tokyo Convention ) has been far from effective.Being regulated by Tokyo Convention, the scope of states which exercise jurisdiction is too narrow , e-ven resulting in "jurisdiction blank".The Protocol To Amend The Convention On Offences And Certain Other Acts Committed On Board Aircraft (The Montreal Protocol, 2014), which was adopted by ICAO (International Civil Avia-tion Organization) in 2014, as the outcome of Tokyo Convention' s modernization, has made new regulations which enlarge the states scope exercising jurisdiction by making the State of landing and the State of the operator have juris -diction (except for the State of registration ), thus, to some extent, making up the gap of the former Tokyo Convention in terms of jurisdiction.This article sorts the evolution of ICAO regulation system in respect of jurisdiction over unrulypassenger cases and explores the significance and shortcomings of existing rules with suggestions for the modificationof relevant domestic provisions.%随着国际民用航空运输业的飞速发展,在航空器上不循规旅客案件数量也呈现激增趋势. 仅仅依照1963年《关于在航空器内的犯罪和其他某些行为的公约》(《东京公约》)已远远不能实现对该类案件的有效规制:因其在管辖权方面的规定过窄,导致很多案件出现"管辖空白"的情况. 国际民航组织2014年通过《关于修订〈关于在航空器内的犯罪和其他某些行为的公约〉的议定书》(《蒙特利尔议定书》),作为《东京公约》现代化的最终成果,对管辖权方面做出了新规定,在原有的航空器登记国管辖权基础上增加了航空器降落地国和航空器

    目的 进一步探索民航机场工作环境噪声对机场工作人员听觉功能的影响.方法 对国内某民航机场的34名工作人员进行了畸变产物耳声发射(distortion product otoacoustic emissions,DPOAE)检查,并比较分析了外场组与室内组、左耳与右耳以及各工龄组间DPOAE信噪比(signal noise ratio,SNR)的幅值和检出率的差异.结果 室内组和外场组各个频率SNR的检出率均小于100%,室内组SNR的幅值和检出率在多个频率点显著高于外场组(P<0.05),以3000 Hz和4000 Hz差异尤为显著(P<0.01);工龄15~ 29年组和30年以上组SNR的幅值和检出率在多个频率点显著高于0~ 14年组(P<0.05),而工龄15~ 29年组和30年以上组间未见显著性差异;左右耳之间SNR的幅值和检出率未见显著性差异.结论 机场噪声对机场工作人员的听觉功能造成了损害,由于外场工作人员噪声暴露强度高于室内工作人员,所以其听觉功能损害程度更加严重;接触噪声时间越长损害越严重.%Objective To further explore the effects of aviation noise exposure in civil airport workplace on the auditory function. Methods Thirty-four staff (68 ears) of a civil aviation airport was tested with distortion product otoacoustic emissions ( DPOAE). The differences of amplitude and detectable rates of signal noise ratio ( SNR) between working inside and outside groups, left and right ear groups, and groups of different working life were compared respectively. Results The detectable rates of SNR in working inside and working outside groups at each frequency were less than 100%. The amplitude and the detectable rates of SNR in working inside group were higher than those in working outside group at multiple frequency points (P <0. 05). The differences of 3000 Hz and 4000 Hz were particularly significant(F <0.01). The amplitude and the detectable rates of SNR of 15 ~29 years and more than 30 years working life groups were higher

    民航实时交易系统通过建立数据同步机制减少对主机系统的数据并发访问.原有的消息队列方法难以支持在大规模并发交易时在实时交易系统中进行数据同步的要求.提出一种新的数据同步方法,将文件数据索引记录和文件同步分离,采用不恢复文件机制的处理,减少系统资源消耗.应用结果表明新方法支持大规模并发交易下的数据同步,并且效果显著.%In civil aviation transaction system, some of passenger information is sent to outside system so that the access to mainframe system could be declined in some way. The message queues in mainframe system could not meet the requirement for large scale parallel processing. Hence, in this article, a new method for the TIP (transaction interface package) file change transfer is introduced simply. In this model, a kind of new index file is used, which is non-recoverable freespace file, and able to faster the data parallel transfer. According to the production application, the new method makes a great improvement to the TIP file change transfer in mainframe side.

    Objective To study human factor accident/incident occurred during 1990~2001 using new classification standard. Method The human factor accident/incident classification standard is developed on the basis of Reason's Model, combining with CAAC's traditional classifying method, and applied to the classified statistical analysis for 361 flying incidents and 35 flight accidents of China civil aviation, which is induced by human factors and occurred from 1990 to 2001. Result 1) the incident percentage of taxi and cruise is higher than that of takeoff, climb and descent. 2) The dominating type of flight incidents is diverging of runway, overrunning, near-miss, tail/wingtip/engine strike and ground obstacle impacting. 3) The top three accidents are out of control caused by crew, mountain collision and over runway. 4) Crew's basic operating skill is lower than what we imagined, the mostly representation is poor correcting ability when flight error happened. 5) Crew errors can be represented by incorrect control, regulation and procedure violation, disorientation and diverging percentage of correct flight level. Conclusion The poor CRM skill is the dominant factor impacting China civil aviation safety, this result has a coincidence with previous study, but there is much difference and distinct characteristic in top incident phase, the type of crew error and behavior performance compared with that of advanced countries. We should strengthen CRM training for all of pilots aiming at the Chinese pilot behavior characteristic in order to improve the safety level of China civil aviation.%目的对中国民航1990~2001年期间发生的人因事故征候和飞行事故进行分类研究.方法 运用Reason事故链模型,结合中国民航的传统分类方法,制订人因事故与事故征候分类标准,在此基础上按分类标准进行分类统计和分析.结果 1)在飞行的各个阶段中,滑行和巡航阶段小于间隔飞行的事故征候发生的百分比高于

    2014-01-01

    Aeromedical implications of stapedotomy like rapid barometric changes and G forces are generally thought to put an end to the aviation career of an aviator. Aviation industry has grown tremendously in the last few decades, and aviation now is not only occupational but also recreational. The Indian Military Aviation rules state that, "Stapedectomy cases will be assessed permanently unfit for flying duties. These cases will be cautioned against flying in an unpressurised aircraft." The basis of this is the aeromedical concerns associated with stapedotomy as clinical conditions which are of minor significance on the ground may become aggravated in the air. With an ever expanding civil and military aviation industry, the number of aviators who have undergone stapedotomy has also increased. Though grounding the aircrew is the safest option, but if medical certification is denied to all, then the majority who can fly safely will also be excluded, thus denying the organization of its trained resources. This paper discusses post otosclerosis and post stapedotomy aeromedical concerns, reviews existing literature concerning post stapedotomy aviation and various post stapedotomy aviation policies.

    Gan, W H; Low, R; Singh, J

    2011-05-01

    Aviation Medicine traces its roots to high altitude physiology more than 400 years ago. Since then, great strides have been made in this medical specialty, initially catalysed by the need to reduce pilot medical attrition during the World Wars, and more recently, fuelled by the explosive growth in globalised commercial air travel. This paper traces the historical milestones in Aviation Medicine, and maps its development in Singapore since the 1960s. Advancements in military aviation platforms and technology as well as the establishment of Singapore as an international aviation hub have propelled Aviation Medicine in Singapore to the forefront of many domains. These span Aviation Physiology training, selection medical standards, performance maximisation, as well as crew and passenger protection against communicable diseases arising from air travel. The year 2011 marks the centennial milestone of the first manned flight in Singapore, paving the way for further growth of Aviation Medicine as a mature specialty in Singapore.

    Full Text Available Normal 0 21 false false false PT-BR X-NONE X-NONE The ethical dimension of the human condition in our times takes increasingly more space in current philosophical discussions. In this context, the ethical principle of responsibility has been widely discussed, particularly by authors who work on the ethical implications of modern technology. In his essay on ethics for the technological age, Hans Jonas proposes to base ethics on a principle of responsibility, taking into account that we live in the age of technological civilization. The present paper explores the origins and sources of Jonas’ principle of responsibility, focusing on the influence of his teacher Martin Heidegger on Jonas’s work. The paper analyses the intrinsic and intriguing relationship between Heidegger’s ontological concept of “care” [Sorge] and the idea or responsibility in Jonas, and it examines further the current discussion on the possibility of an ethical foundation for the techno scientific civilization.

Operating Costs: GA operating costs have risen dramatically due to average fuel costs of over $6 per gallon, which has constrained the market over the past decade and resulted in more than 50% lower sales and 35% less yearly operations. Infusion of autonomy and electric propulsion technologies can accomplish not only a transformation of the GA market, but also provide a technology enablement bridge for both larger aircraft and the emerging civil Unmanned Aerial Systems (UAS) markets. The NASA Advanced General Aviation Transport Experiments (AGATE) project successfully used a similar approach to enable the introduction of primary composite structures and flat panel displays in the 1990s, establishing both the technology and certification standardization to permit quick adoption through partnerships with industry, academia, and the Federal Aviation Administration (FAA). Regional and airliner markets are experiencing constant pressure to achieve decreasing levels of community emissions and noise, while lowering operating costs and improving safety. But to what degree can these new technology frontiers impact aircraft safety, the environment, operations, cost, and performance? Are the benefits transformational enough to fundamentally alter aircraft competiveness and productivity to permit much greater aviation use for high speed and On-Demand Mobility (ODM)? These questions were asked in a Zip aviation system study named after the Zip Car, an emerging car-sharing business model. Zip Aviation investigates the potential to enable new emergent markets for aviation that offer "more flexibility than the existing transportation solutions

    Science.gov (United States)

    Lansdown, A. R.; Lee, S.

    Aviation lubricants must be extremely reliable, withstand high specific loadings and extreme environmental conditions within short times. Requirements are critical. Piston engines increasingly use multi-grade oils, single grades are still used extensively, with anti-wear and anti-corrosion additives for some classes of engines. The main gas turbine lubricant problem is transient heat exposure, the main base oils used are synthetic polyol esters which minimise thermal degradation. Aminic anti-oxidants are used together with anti-wear/load-carrying, corrosion inhibitor and anti-foam additives. The majority of formulation viscosities are 5 cSt at 100°C. Other considerations are seal compatibility and coking tendency.

    1977-01-01

    The efficient utilization of fossil fuels by future jet aircraft may necessitate the broadening of current aviation turbine fuel specifications. The most significant changes in specifications would be an increased aromatics content and a higher final boiling point in order to minimize refinery energy consumption and costs. These changes would increase the freezing point and might lower the thermal stability of the fuel and could cause increased pollutant emissions, increased smoke and carbon formation, increased combustor liner temperatures, and poorer ignition characteristics. This paper discusses the effects that broadened specification fuels may have on present-day jet aircraft and engine components and the technology required to use fuels with broadened specifications.

    2010-01-01

    The right of a person to be protected from natural hazards is a characteristic of the social and economical development of the society. This paper is a contribution to the reflection about the role of Civil Protection organizations in a modern society. The paper is based in the inaugural conference made by the authors on the 9th Plinius Conference on Mediterranean Storms. Two major issues are considered. The first one is sociological; the Civil Protection organizations and the responsible administration of the land use planning should be perceived as reliable as possible, in order to get consensus on the restrictions they pose, temporary or definitely, on the individual free use of the territory as well as in the entire warning system. The second one is technological: in order to be reliable they have to issue timely alert and warning to the population at large, but such alarms should be as "true" as possible. With this aim, the paper summarizes the historical evolution of the risk assessment, starting from the original concept of "hazard", introducing the concepts of "scenario of event" and "scenario of risk" and ending with a discussion about the uncertainties and limits of the most advanced and efficient tools to predict, to forecast and to observe the ground effects affecting people and their properties. The discussion is centred in the case of heavy rains and flood events in the North-West of Mediterranean Region.

  17. Entrepreneurship within General Aviation

    Ullmann, Brian M.

    1995-01-01

    Many modern economic theories place great importance upon entrepreneurship in the economy. Some see the entrepreneur as the individual who bears risk of operating a business in the face of uncertainty about future conditions and who is rewarded through profits and losses. The 20th century economist Joseph Schumpter saw the entrepreneur as the medium by which advancing technology is incorporated into society as businesses seek competitive advantages through more efficient product development processes. Due to the importance that capitalistic systems place upon entrepreneurship, it has become a well studied subject with many texts to discuss how entrepreneurs can succeed in modern society. Many entrepreneuring and business management courses go so far as to discuss the characteristic phases and prominent challenges that fledgling companies face in their efforts to bring a new product into a competitive market. However, even with all of these aids, start-up companies fail at an enormous rate. Indeed, the odds of shepherding a new company through the travails of becoming a well established company (as measured by the ability to reach Initial Public Offering (IPO)) have been estimated to be six in 1,000,000. Each niche industry has characteristic challenges which act as barriers to entry for new products into that industry. Thus, the applicability of broad generalizations is subject to limitations within niche markets. This paper will discuss entrepreneurship as it relates to general aviation. The goals of this paper will be to: introduce general aviation; discuss the details of marrying entrepreneurship with general aviation; and present a sample business plan which would characterize a possible entrepreneurial venture.

    1999-01-01

    In the Task I portion of this NASA research grant, configuration development and experimental investigations have been conducted on a series of pneumatic high-lift and control surface devices applied to a generic High Speed Civil Transport (HSCT) model configuration to determine their potential for improved aerodynamic performance, plus stability and control of higher performance aircraft. These investigations were intended to optimize pneumatic lift and drag performance; provide adequate control and longitudinal stability; reduce separation flowfields at high angle of attack; increase takeoff/climbout lift-to-drag ratios; and reduce system complexity and weight. Experimental aerodynamic evaluations were performed on a semi-span HSCT generic model with improved fuselage fineness ratio and with interchangeable plain flaps, blown flaps, pneumatic Circulation Control Wing (CCW) high-lift configurations, plain and blown canards, a novel Circulation Control (CC) cylinder blown canard, and a clean cruise wing for reference. Conventional tail power was also investigated for longitudinal trim capability. Also evaluated was unsteady pulsed blowing of the wing high-lift system to determine if reduced pulsed mass flow rates and blowing requirements could be made to yield the same lift as that resulting from steady-state blowing. Depending on the pulsing frequency applied, reduced mass flow rates were indeed found able to provide lift augmentation at lesser blowing values than for the steady conditions. Significant improvements in the aerodynamic characteristics leading to improved performance and stability/control were identified, and the various components were compared to evaluate the pneumatic potential of each. Aerodynamic results were provided to the Georgia Tech Aerospace System Design Lab. to conduct the companion system analyses and feasibility study (Task 2) of theses concepts applied to an operational advanced HSCT aircraft. Results and conclusions from these

    Aviation technology, i.e. aircraft, control and airfield infrastructure wear out, become defective and need servicing. It seems indispensible to maintain facilities and spare parts at a level necessary to keep the technology in commission. The paper discusses the factors influencing spare parts supply requirements to secure air operations. Aviation technology has been classified with regard to various criteria, which influence the choice of supply management strategies, along with availability and aircraft exploitation cost. The method of optimization of the stock for a complex system characterized by series reliability structure according to the wear-out and cost criteria assuming Poisson's process of demand has been presented.

  14. THE POETIC VECTOR OF CIVILIZATION

    Directory of Open Access Journals (Sweden)

    Mikhail Epstein

    2016-01-01

    Full Text Available The article regards poetry as the type of a world view that has profound effect on the social and technical development of civilization. Contrary to popular belief about the decline of poetry in the technological age, poetry, as the desire for imaginative comprehension and transformation of the world, remains the most powerful engine of civilization. There are new, non-linguistic forms of existence of poetry (outside of verses and books that are explored in the article: anthropoeia, biopoeia, kosmopoeia, noopoeia, sociopoeia, technopoeia… For example, the technique is no less metaphorical and symbolic than poetry is, but it embodies the energy of creation not in words, but in the poetically transfigured matter where each element is „playing” with nature, overcomes the force of gravity, the distances of time and space. Tehnopoeia as realized in aviation, rocketry, electronics, Internet, new means of communication, allows to see clearly the invisible, to hear the inaudible, to speak many languages. Technopoeia is the poetic aspect of technology as an activity that implements the creative aspirations of humans and the symbolic vision of the world. The article examines the „physics of poetry,” as it was understood by Surrealists, and shows that the poetic perception of things is not opposed to its utilitarian functions, but both can be harmoniously combined. Contemporatry science and technology aspire to implement a number of fundamental biopoetic and cosmopoetic metaphors: the universe — a computer, a planet — a living organism, the computer — the brain, the Internet — the nervous system, infectious viruses — computer and genes, the language of life — the process of writing… The metaphor becomes an integral part of the scientific outlook and the driving force behind the new discovery. Philology and poetics need to develop new methods of analysis of poetic phenomena as embodied not in verses, but in scientific thinking and

  2. Direct carbon dioxide emissions from civil aircraft

    Grote, Matt; Williams, Ian; Preston, John

    2014-10-01

    Global airlines consume over 5 million barrels of oil per day, and the resulting carbon dioxide (CO2) emitted by aircraft engines is of concern. This article provides a contemporary review of the literature associated with the measures available to the civil aviation industry for mitigating CO2 emissions from aircraft. The measures are addressed under two categories - policy and legal-related measures, and technological and operational measures. Results of the review are used to develop several insights into the challenges faced. The analysis shows that forecasts for strong growth in air-traffic will result in civil aviation becoming an increasingly significant contributor to anthropogenic CO2 emissions. Some mitigation-measures can be left to market-forces as the key-driver for implementation because they directly reduce airlines' fuel consumption, and their impact on reducing fuel-costs will be welcomed by the industry. Other mitigation-measures cannot be left to market-forces. Speed of implementation and stringency of these measures will not be satisfactorily resolved unattended, and the current global regulatory-framework does not provide the necessary strength of stewardship. A global regulator with ‘teeth' needs to be established, but investing such a body with the appropriate level of authority requires securing an international agreement which history would suggest is going to be very difficult. If all mitigation-measures are successfully implemented, it is still likely that traffic growth-rates will continue to out-pace emissions reduction-rates. Therefore, to achieve an overall reduction in CO2 emissions, behaviour change will be necessary to reduce demand for air-travel. However, reducing demand will be strongly resisted by all stakeholders in the industry; and the ticket price-increases necessary to induce the required reduction in traffic growth-rates place a monetary-value on CO2 emissions of approximately 7-100 times greater than other common

  3. General aviation in China

    Science.gov (United States)

    Hu, Xiaosi

    In the last four decades, China has accomplished economic reform successfully and grown to be a leading country in the world. As the "world factory", the country is able to manufacture a variety of industrial products from clothes and shoes to rockets and satellites. But the aviation industry has always been a weak spot and even the military relies on imported turbofan engines and jet fighters, not to mention the airlines. Recently China has launched programs such as ARJ21 and C919, and started reform to change the undeveloped situation of its aviation industry. As the foundation of the aviation industry, the development of general aviation is essential for the rise of commercial aviation. The primary goal of this study is to examine the general aviation industry and finds the issues that constrain the development of the industry in the system. The research method used in this thesis is the narrative research of qualitative approach since the policy instead of statistical data is analyzed. It appears that the main constraint for the general aviation industry is the government interference.

  8. Improving Aviation Safety in Indonesia: How Many More Accidents?

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Numerous and consecutive aircraft accidents combined with a consistent failure to meet international safety standards in Indonesia, namely from the International Civil Aviation Organization and the European Aviation Safety Agency have proven a nightmare for the country’s aviation safety reputation. There is an urgent need for bureaucracy reform, harmonization of legislation, and especially ensuring legal enforcement, to bring Indonesian aviation safety back to world standards. The Indonesian Aviation Law of 2009 was enacted to reform the situation in Indonesia. The law has become the ground for drafting legal framework under decrees of the Minister of Transportation, which have allowed the government to perform follow-up actions such as establishing a single air navigation service provider and guaranteeing the independency of the Indonesian National Transportation Safety Committee. A comparison with Thailand is made to enrich the perspective. Finally, foreign aviation entities have a role to assist states, in this case Indonesia, in improving its aviation safety, considering the global nature of air travel.

  9. The United States national volcanic ash operations plan for aviation

    Science.gov (United States)

    Albersheim, Steven; Guffanti, Marianne

    2009-01-01

    Volcanic-ash clouds are a known hazard to aviation, requiring that aircraft be warned away from ash-contaminated airspace. The exposure of aviation to potential hazards from volcanoes in the United States is significant. In support of existing interagency operations to detect and track volcanic-ash clouds, the United States has prepared a National Volcanic Ash Operations Plan for Aviation to strengthen the warning process in its airspace. The US National Plan documents the responsibilities, communication protocols, and prescribed hazard messages of the Federal Aviation Administration, National Oceanic and Atmospheric Administration, US Geological Survey, and Air Force Weather Agency. The plan introduces a new message format, a Volcano Observatory Notice for Aviation, to provide clear, concise information about volcanic activity, including precursory unrest, to air-traffic controllers (for use in Notices to Airmen) and other aviation users. The plan is online at http://www.ofcm.gov/p35-nvaopa/pdf/FCM-P35-2007-NVAOPA.pdf. While the plan provides general operational practices, it remains the responsibility of the federal agencies involved to implement the described procedures through orders, directives, etc. Since the plan mirrors global guidelines of the International Civil Aviation Organization, it also provides an example that could be adapted by other countries.

  11. Subsidies in Aviation

    Directory of Open Access Journals (Sweden)

    Stefan Gössling

    2017-07-01

    Full Text Available Relatively little attention has been paid to the existence of subsidies in aviation. As the sector’s importance for economic development is often highlighted, this paper seeks to provide a conceptual overview of the various forms of subsidies in aviation, as a contribution to a more holistic understanding of economic interrelationships. Based on a purposive sampling strategy, existing forms of subsidies are identified and categorized along the value chain. Focus is on industrialized countries, for which more information is available. Results indicate that significant subsidies are extended to manufacturers, infrastructure providers and airlines. These contribute to global economic growth related to aviation, but they also influence capacity in global aviation markets, strengthen the market position of individual airlines, and create conflicts between airlines and the countries they are based in. While the actual scale of subsidies cannot be determined within the scope of this paper, it provides a discussion of options to empirically assess the effects of aviation subsidies on market outcomes. Finally, general conclusions regarding the impact of subsidies on the overall sustainability of the air transport sector are drawn: These include rapidly growing capacity in the aviation system, economic vulnerabilities, and negative climate change related impacts. Results call for a better understanding of the distribution, character and implications of subsidies.

    Science.gov (United States)

    Afanas'ev, R V; Berezin, G I; Raznoschikov, V V

    2004-01-01

    Cryogenic fuels are viewed as an alternative to the commonly used hydrocarbonic fuels. The existing national and international guidelines set limits to the emission of unburned carbohydrates (CnHm), carbon monoxide (CO), nitrogen oxides (NO(x)), and soot (SN); there is also prohibition against premeditated fuel discharge in atmosphere of airports. Whereas the international regulations are constantly revised toward toughening, more than 80% of the plane engines in the Russian civil aviation do not meet both national and international harmful emission limits. One of the ways to resolve the problem is substitution of the liquid carbohydrate fuel (kerosene) by natural gas.

  14. The effects of aircraft certification rules on general aviation accidents

    Science.gov (United States)

    Anderson, Carolina Lenz

    -Square test indicated that there was no significant difference in the number of accidents among the different certification categories when either Controlled Flight into Terrain or Structural Failure was listed as cause. However, there was a significant difference in the frequency of accidents with regard to Loss of Control and Engine Failure accidents. The results of the ANCOVA test indicated that there was no significant difference in the accident rate with regard to Loss of Control, Controlled Flight into Terrain, or Structural Failure accidents. There was, however, a significant difference in Engine Failure accidents between Experimental-Amateur Built and the other categories.The text mining analysis of the narrative causes of Loss of Control accidents indicated that only the Civil Air Regulations 3 category airplanes had clusters of words associated with visual flight into instrument meteorological conditions. Civil Air Regulations 3 airplanes were designed and manufactured prior to the 1960s and in most cases have not been retrofitted to take advantage of newer technologies that could help prevent Loss of Control accidents. The study indicated that General Aviation aircraft certification rules do not have a statistically significant effect on aircraft accidents except for Loss of Control and Engine Failure. According to the literature, government oversight could have become an obstacle in the implementation of safety enhancing equipment that could reduce Loss of Control accidents. Oversight should focus on ensuring that Experimental-Amateur Built aircraft owners perform a functional test that could prevent some of the Engine Failure accidents.

    Full Text Available The environmental impact by civil aviation activity at all stages of air-transport service life cycle is considered in the article. Negative emergency aviation situations make certain changes to life cycle of the service offered by air transport that is reflected in negative ecological environmental impact at the place of accident. The integrated approach to an assess- ment of such influence is required. The amount of the polluting substances getting into the soil of the ecosystem at the site of an aircraft accident can be considerably reduced by means of timely extraction by carbon adsorption of the aviation fuel and special liquids, that is soil detoxication is required.Expediency of placement of the special sorption barrier passing on the border of the aviation accident area and representing the water-permeable sleeve filled with a sorbent is proved. The stage-by-stage sequence of the detoxication works is offered and it is recommended to apply their carrying out in civil aviation in the form of the obligatory task imput- ed to the administrative subcommittee, which is a part of the aircraft accident investigation committee.The sequence of works is presented in the form of the plan schedule of necessary actions.

It can be designed as integrated ESP (English for Specific Purposes curricula for students in the fields of aeronautics and/or aviation. Learners of ESP are supposed to master the vocabulary in their specific discipline as well as the English language skills. This paper explores the possibility of establishing Aviation English as an ESP specialty in aeronautical and/or aviation colleges and universities. Needs analysis has been made and curricula designed for an integrated course of study in the Chinese context, so that learners of ESP can learn the target language more effectively and meet the standards set by the International Civil Aviation Organization (ICAO. It reconsiders the ESP theories and aims to develop a possible approach to ESP teaching more suitable for the Chinese learners.

    2015-12-01

    Remotely piloted aviation systems (RPAS) or 'drones' are well known for their military applications, but could also be used for a range of non-military applications for state, industrial, commercial and recreational purposes. The technology is advanced and regulatory changes are underway which will allow their use in domestic airspace. As well as the functional and economic benefits of a strong civil RPAS sector, the potential benefits for the military RPAS sector are also widely recognised. Several actors have nurtured this dual-use aspect of civil RPAS development. However, concerns have been raised about the public rejecting the technology because of their association with military applications and potentially controversial applications, for example in policing and border control. In contrast with the enthusiasm for dual-use exhibited throughout the EC consultation process, the strategy for avoiding public rejection devised in its roadmap would downplay the connection between military and non-military RPAS and focus upon less controversial applications such as search and rescue. We reflect upon this contrast in the context of the European agenda of responsible research and innovation. In doing so, we do not rely upon critique of drones per se, in their neither their civil nor military guise, but explore the extent to which current strategies for managing their public acceptability are compatible with a responsible and socially beneficial development of RPAS for civil purposes.

    International Civil Aviation Organization’s (ICAO) International Airways Volcano Watch. This plan defines agency responsibilities, provides a comprehensive description of an interagency standard for volcanic ash products and their formats, describes the agency backup procedures for operational products, and outlines the actions to be taken by each agency following an occurrence of a volcanic eruption that subsequently affects and impacts aviation services. Since our most recent International Conference on Volcanic Ash and Aviation Safety, volcanic ash-related product and service activities have grown considerably along with partnerships and alliances throughout the aviation community. In January 2005, the National Oceanic and Atmospheric Administration’s National Centers for Environment Prediction began running the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model in place of the Volcanic Ash Forecast Transport and Dispersion (VAFTAD) model, upgrading support to the volcanic ash advisory community. Today, improvements to the HYSPLIT model are ongoing based on recommendations by the OFCM-sponsored Joint Action Group for the Selection and Evaluation of Atmospheric Transport and Diffusion Models and the Joint Action Group for Atmospheric Transport and Diffusion Modeling (Research and Development Plan). Two international workshops on volcanic ash have already taken place, noticeable improvements and innovations in education, training, and outreach have been made, and federal and public education and training programs on volcanic ash-related products, services, and procedures iv continue to evolve. For example, in partnership with Embry-Riddle Aeronautical University and other academic institutions, volcanic ash hazard and mitigation training has been incorporated into aviation meteorology courses. As an essential next step, our volcanic ash-related efforts in the near term will be centered on the development of an interagency implementation plan to

  14. Modelling climate impacts on the aviation sector

    Science.gov (United States)

    Williams, Paul

    2017-04-01

    The climate is changing, not just where we live at ground level, but also where we fly at 35,000 feet. We have long known that air travel contributes to climate change through its emissions. However, we have only recently become aware that climate change could have significant consequences for air travel. This presentation will give an overview of the possible impacts of climate change on the aviation sector. The presentation will describe how the impacts are modelled and how their social and economic costs are estimated. The impacts are discussed in the International Civil Aviation Organization's (ICAO's) latest Environmental Report (Puempel and Williams 2016). Some of the possible impacts are as follows. Rising sea levels and storm surges threaten coastal airports, such as La Guardia in New York, which was flooded by the remnants of Hurricane Sandy in 2012. Warmer air at ground level reduces the lift force and makes it more difficult for planes to take-off (Coffel and Horton 2015). More extreme weather may cause flight disruptions and delays. Clear-air turbulence is expected to become up to 40% stronger and twice as common (Williams and Joshi 2013). Transatlantic flights may collectively be airborne for an extra 2,000 hours each year because of changes to the jet stream, burning an extra 7.2 million gallons of jet fuel at a cost of US 22 million, and emitting an extra 70 million kg of carbon dioxide (Williams 2016). These modelled impacts provide further evidence of the two-way interaction between aviation and climate change.

  15. Synthetic and Biomass Alternate Fueling in Aviation

    Science.gov (United States)

    Hendricks, R. C.; Bushnell, D. M.

    2009-01-01

    While transportation fueling can accommodate a broad range of alternate fuels, aviation fueling needs are specific, such as the fuel not freezing at altitude or become too viscous to flow properly or of low bulk energy density that shortens range. The fuel must also be compatible with legacy aircraft, some of which are more than 50 years old. Worldwide, the aviation industry alone uses some 85-95 billion gallons of hydrocarbon-based fossil fuel each year, which is about 10% of the transportation industry. US civil aviation alone consumes nearly 14 billion gallons. The enormity of the problem becomes overwhelming, and the aviation industry is taking alternate fueling issues very seriously. Biofuels (algae, cyanobacteria, halophytes, weeds that use wastelands, wastewater and seatwater), when properly sourced, have the capacity to be drop-in fuel replacements for petroleum fuels. As such, biojet from such sources solves the aviation CO2 emissions issue without the downsides of 'conventional' biofuels, such as competing with food and fresh water resources. Of the many current fundamental problems, the major biofuel problem is cost. Both research and development and creative engineering are required to reduce these biofuels costs. Research is also ongoing in several 'improvement' areas including refining/processing and biologics with greater disease resistance, greater bio-oil productivity, reduced water/nutrient requirements, etc. The authors' current research is aimed at aiding industry efforts in several areas. They are considering different modeling approaches, growth media and refining approaches, different biologic feedstocks, methods of sequestering carbon in the processes, fuel certification for aviation use and, overall, ensuring that biofuels are feasible from all aspects - operability, capacity, carbon cycle and financial. The authors are also providing common discussion grounds/opportunities for the various parties, disciplines and concerned organization to

    The monitoring of strategic civil infrastructures to ensure their structural integrity is a task of major importance, especially in earthquake-prone areas. Classical approaches to such monitoring are based on visual inspections and the use of wired systems. While the former has the drawback that the structure is only superficially examined and discontinuously in time, wired systems are relatively expensive and time consuming to install. Today, however, wireless systems represent an advanced, easily installed and operated tool to be used for monitoring purposes, resulting in a wide and interesting range of possible applications. Within the framework of the earthquake early warning projects SAFER (Seismic eArly warning For EuRope) and EDIM (Earthquake Disaster Information systems for the Marmara Sea region, Turkey), new low-cost wireless sensors with the capability to automatically rearrange their communications scheme are being developed. The reduced sensitivity of these sensors, arising from the use of low-cost components, is compensated by the possibility of deploying high-density self-organizing networks performing real-time data acquisition and analysis. Thanks to the developed system's versatility, it has been possible to perform an experimental ambient vibration test with a network of 24 sensors on the Fatih Sultan Mehmet Bridge, Istanbul (Turkey), a gravity-anchored suspension bridge spanning the Bosphorus Strait with distance between its towers of 1090 m. Preliminary analysis of the data has demonstrated that the main modal properties of the bridge can be retrieved, and may therefore be regularly re-evaluated as part of a long-term monitoring program. Using a multi-hop communications technique, data could be exchanged among groups of sensors over distances of a few hundred meters. Thus, the test showed that, although more work is required to optimize the communication parameters, the performance of the network offers encouragement for us to follow this

  19. Corporate Social Responsibility in Aviation

    Phillips, Edwin D.

    2006-01-01

    The dialog within aviation management education regarding ethics is incomplete without a discussion of corporate social responsibility (CSR). CSR research requires discussion involving: (a) the current emphasis on CSR in business in general and aviation specifically; (b) business and educational theory that provide a basis for aviation companies to engage in socially responsible actions; (c) techniques used by aviation and aerospace companies to fulfill this responsibility; and (d) a glimpse of teaching approaches used in university aviation management classes. The summary of this research suggests educators explain CSR theory and practice to students in industry and collegiate aviation management programs. Doing so extends the discussion of ethical behavior and matches the current high level of interest and activity within the aviation industry toward CSR.

    Science.gov (United States)

    Ju, Chengting; Ji, Ming; Lan, Jijun; You, Xuqun

    2016-01-28

    Optimism bias is a crucial feature of risk perception that leads to increased risk-taking behaviour, which is a particularly salient issue among pilots in aviation settings due to the high-stakes nature of flight. The current study sought to address the roles of narcissism and promotion focus on optimism bias in risk perception in aviation context. Participants were 239 male flight cadets from the Civil Aviation Flight University of China who completed the Narcissistic Personality Inventory-13, the Work Regulatory Focus Scale, and an indirect measure of unrealistic optimism in risk perception, which measured risk perception for the individual and the risk assumed by other individuals performing the same task. Higher narcissism increased the likelihood of underestimating personal risks, an effect that was mediated by high promotion focus motivation, such that high narcissism led to high promotion focus motivation. The findings have important implications for improving the accuracy of risk perception in aviation risks among aviators.

    Full Text Available Poland, as a member of the EU, is represented within the ICAO, by the European Aviation Safety Agency. However, this does not relieve our country from the responsibility of developing a state safety programme (SSP. The need to set up such a programme, which has to be specific to every country involved in aviation operation, was introduced by the ICAO’s Annex 19. One of the important points in Annex 19 is: “5.2.1 Each State shall establish and maintain a safety database to facilitate the effective analysis of information on actual or potential safety deficiencies obtained, including that from its incident reporting systems, and to determine any actions required for the enhancement of safety”. The Polish Civil Aviation Authority, along with other databases, manages the European Coordination Centre for Aviation Incident Reporting Systems (ECCAIRS. The authors (who are specialists dealing with exploitation processes in aviation have conducted a laborious processing of the data contained in the ECCAIRS database, analysing them based on various criteria: aviation occurrence categories (as defined by the ICAO, phases of flight for different airports in Poland etc. Aircraft with an maximum take-off mass (MTOM 5,700 kg (commercial aviation were considered separately. It was found that the most events are those that relate to power plant (SCF-PP airframes and related system (SCF-NP failures, followed by collisions with birds (BIRD, events related to airports (ADRM and events related to the required separation of aircraft (MAC. For lighter aircraft, the dominant categories are ARC, CTOL, GTOW and LOC-I events. The article presents a proposed method for predicting the number of events, determining the alert levels for the next years and assuming a normal distribution (Gaussian. It is one of the first attempts to use actual data contained in the database of events on airports in Poland. The results of this analysis may support the decisions of

    1979-01-01

    The small engine technology requirements suitable for general aviation service in the 1987 to 1988 time frame were defined. The market analysis showed potential United States engines sales of 31,500 per year providing that the turbine engine sales price approaches current reciprocating engine prices. An optimum engine design was prepared for four categories of fixed wing aircraft and for rotary wing applications. A common core approach was derived from the optimum engines that maximizes engine commonality over the power spectrum with a projected price competitive with reciprocating piston engines. The advanced technology features reduced engine cost, approximately 50 percent compared with current technology.

    Ou, Jinping

    2006-03-01

    Intelligent sensing technologies have developed rapidly recent years, which meet the requirement of structural health monitoring (SHM). A number of types of intelligent sensing technologies have been developed in the mainland of China, such as optical fiber sensing technology, piezoelectric sensing technology, self-sensing smart materials, wireless sensors and sensor networks, CCD, GPS and so on. In this paper, various optical fiber sensors are introduced, including optical fiber sensors, six kinds of optical fiber Bragg grating (OFBG)-based sensors, fiber reinforced bars embedded with OFBG sensors (FRP-OFBG), OFBG-based smart cables, OFBG-based weighbridge, PVDF-based strain gauge and crack meter, shape memory alloy-based displacement transducer, self-sensing cement-based strain gauge, wireless accelerometers and sensor networks, wireless strain sensors and sensor networks, and GPS. The performance of various sensors mentioned above is also experimentally investigated, in particular sensing property, durability, fatigue and corrosion resistant performance. Additionally, applications of the sensors have also been carried out in the mainland of China. The full implementation of sensors in SHM systems for offshore platforms, long-span bridges, large-span domes, tall buildings and so on are also introduced in this paper.

  15. Aviation instruction through flight simulation and related learning

    Science.gov (United States)

    Green, Mavis Frankel

    The use of simulation in General Aviation flight training is an emergent practice and promises to increase substantially. Training through simulation is not addressed in the primary publication used to train flight instructors, however. In effect, training devices have been added into the curriculum by those using the technology as a cross between flight and ground instruction. The significance of how one learns in a training device is the potential effect on both in-flight learning and normal practices. A review of the literature, document review, interviews with flight instructors and students, and observations of instructional sessions in training devices, provided data to answer the prime research question: (a) What type(s) of learning best explain how learners are socialized to aviation through the use of simulation technology? One segment of the general aviation population, college and university flight programs, was sampled. Four types of learning provided a conceptual framework: reception; autonomous; guided inquiry; and social cognitive operationalized as cognitive apprenticeship. A central dilemma was identified from the data collected. This dilemma is the extent to which aviation and aviation instruction in training devices is perceived by instructors as being either safe or risky. Two sub-dilemmas of the central dilemma are also identified: (1) whether the perception of aviation on the part of instructors is one of control or autonomy and (2) whether aviators use and should be taught routines or innovation;. Three ways of viewing the aviation environment were identified from the combination of these sub-dilemmas by instructors: (1) aviation as safe; (2) aviation as somewhat safe; and (3) aviation as risky. Resolution of the fundamental dilemma results in an emergent view of aviation as risky and the implications of this view are discussed. Social cognitive learning operationalized as cognitive apprenticeship as an appropriate type of learning for high

    2015-01-01

    Full Text Available The aviation industry has set ambitious goals to reduce carbon emissions in coming decades. The strategy involves the use of sustainable biofuels, aiming to achieve benefits from environmental, social, and economic perspectives. In this context, Brazilian conditions are favorable, with a mature agroindustry that regularly produces automotive biofuel largely adopted by Brazilian road vehicles, while air transportation has been growing at an accelerating pace and a modern aircraft industry is in place. This paper presents the main conclusions and recommendations from a broad assessment of the technological, economic, and sustainability challenges and opportunities associated with the development of drop-in aviation biofuels in Brazil. It was written by a research team that prepared the initial reports and conducted eight workshops with the active participation of more than 30 stakeholders encompassing the private sector, government institutions, NGOs, and academia. The main outcome was a set of guidelines for establishing a new biofuels industry, including recommendations for (a filling the identified research and development knowledge gaps in the production of sustainable feedstock; (b overcoming the barriers in conversion technology, including scaling-up issues; (c promoting greater involvement and interaction between private and government stakeholders; and (d creating a national strategy to promote the development of aviation biofuels.

  4. Prospective Safety Analysis and the Complex Aviation System

    Science.gov (United States)

    Smith, Brian E.

    2013-01-01

    Fatal accident rates in commercial passenger aviation are at historic lows yet have plateaued and are not showing evidence of further safety advances. Modern aircraft accidents reflect both historic causal factors and new unexpected "Black Swan" events. The ever-increasing complexity of the aviation system, along with its associated technology and organizational relationships, provides fertile ground for fresh problems. It is important to take a proactive approach to aviation safety by working to identify novel causation mechanisms for future aviation accidents before they happen. Progress has been made in using of historic data to identify the telltale signals preceding aviation accidents and incidents, using the large repositories of discrete and continuous data on aircraft and air traffic control performance and information reported by front-line personnel. Nevertheless, the aviation community is increasingly embracing predictive approaches to aviation safety. The "prospective workshop" early assessment tool described in this paper represents an approach toward this prospective mindset-one that attempts to identify the future vectors of aviation and asks the question: "What haven't we considered in our current safety assessments?" New causation mechanisms threatening aviation safety will arise in the future because new (or revised) systems and procedures will have to be used under future contextual conditions that have not been properly anticipated. Many simulation models exist for demonstrating the safety cases of new operational concepts and technologies. However the results from such models can only be as valid as the accuracy and completeness of assumptions made about the future context in which the new operational concepts and/or technologies will be immersed. Of course that future has not happened yet. What is needed is a reasonably high-confidence description of the future operational context, capturing critical contextual characteristics that modulate

    Full Text Available The investigations of thermal and technical features of enveloping structures show that at the present time the structures of outer walls with hinged ventilated facades are the most energy efficient. The facades with air space are widely used both in residential and in public buildings. In the recent years the problems related to energy efficient enveloping structures are being actively investigated. The problems of modern Russian and foreign energy-efficient facade systems, their technical and structural solutions and the main methods of their installation are reviewed in the article. The methods of solving the tasks of research are proposed and the obtained results are described. The development of organizational and technological solutions for sealing of joints of front panels during installation of ventilated facades by pre-assembly method was the basis of the method of solving of the problem. The obtained data together with the developed structural and technological solutions may become the base for the development of technical rules and regulations.

    Achieving the healthcare components of the United Nations' Millennium Development Goals is significantly premised on effective service delivery by civil society organisations (CSOs). However, many CSOs across Africalack the necessary capacity to perform this role robustly. This paper reports on an evaluation of the use, and perceived impact, of aknowledge management tool upon institutional strengthening among CSOs working in Kenya's health sector. Three methods were used: analytics data; user satisfaction surveys; and a furtherkey informant survey. Satisfaction with the portal was consistently high, with 99% finding the quality and relevance of the content very good or good for institutional strengthening standards, governance, and planning and resource mobilisation. Critical facilitators to the success of knowledge management for CSO institutional strengthening were identified as people/culture (developed resources and organisational narratives) and technology (easily accessible, enabling information exchange, tools/resources available, access to consultants/partners). Critical barriers were identified as people/culture (database limitations, materials limitations, and lack of active users), and process (limited access, limited interactions, and limited approval process). This pilot study demonstrated the perceived utility of a web-based knowledge management portal among developing nations' CSOs, with widespread satisfaction across multiple domains, which increased over time. Providing increased opportunities for collective mutual learning, promoting a culture of data use for decision making, and encouraging all health organisations to be learning institutions should be a priority for those interested in promoting sustainable long-term solutions for Africa.

    In response to the Air Force directive to remove Ozone Depleting Chemicals (ODC's) from military specifications and Defense Logistics Agency's Hazardous Waste Minimization Program, we are faced with how to ensure a quality aviation fuel without using such chemicals. Many of these chemicals are found throughout the fuel and fuel related military specifications and are part of test methods that help qualify the properties and quality of the fuels before they are procured. Many years ago there was a directive for military specifications to use commercially standard test methods in order to provide standard testing in private industry and government. As a result the test methods used in military specifications are governed by the American Society of Testing and Materials (ASTM). The Air Force has been very proactive in the removal or replacement of the ODC's and hazardous materials in these test methods. For example, ASTM D3703 (Standard Test Method for Peroxide Number of Aviation Turbine Fuels), requires the use of Freon 113, a known ODC. A new rapid, portable hydroperoxide test for jet fuels similar to ASTM D3703 that does not require the use of ODC's has been developed. This test has proved, in limited testing, to be a viable substitute method for ASTM D3703. The Air Force is currently conducting a round robin to allow the method to be accepted by ASTM and therefore replace the current method. This paper will describe the Air Force's initiatives to remove ODC's and hazardous materials from the fuel and fuel related military specifications that the Air Force Wright Laboratory.

  19. Safer Aviation Materials Tested

    Palaszewski, Bryan A.

    2001-01-01

    A series of thermally stable polymer samples were tested. These materials are called low heat release materials and are designed for aircraft interior decorative materials. The materials are designed to give off a minimum amount of noxious gases when heated, which increases the possibility that people can escape from a burning aircraft. New cabin materials have suitably low heat release so that fire does not spread, toxic chemicals are not given off, and the fire-emergency escape time for crew and passengers is lengthened. These low heat-release materials have a variety of advantages and applications: interiors for ground-based facilities, interiors of space vehicles, and many commercial fire-protection environments. A microscale combustion calorimeter at the Federal Aviation Administration's (FAA) Technical Center tested NASA Langley Research Center materials samples. The calorimeter is shown. A sharp, quantitative, and reproducible heat-release-rate peak is obtained in the microscale heat-release-rate test. The newly tested NASA materials significantly reduced the heat release capacity and total heat release. The thermal stability and flammability behavior of the samples was very good. The new materials demonstrated a factor of 4 reduction in total heat release over ULTEM (a currently used material). This information is provided in the following barchart. In other tests, the materials showed greater than a factor 9 reduction in heat-release capacity over ULTEM. The newly tested materials were developed for low dielectric constant, low color, and good solubility. A scale up of the material samples is needed to determine the repeatability of the performance in larger samples. Larger panels composed of the best candidate materials will be tested in a larger scale FAA Technical Center fire facility. The NASA Glenn Research Center, Langley (Jeff Hinkley), and the FAA Technical Center (Richard Lyon) cooperatively tested these materials for the Accident Mitigation

    During the recent (12--22 June 1991) Mount Pinatubo volcano eruptions, the US Air Force Global Weather Central (AFGWC) requested assistance of the US Department of Energy`s Atmospheric Release Advisory Capability (ARAC) in creating volcanic ash cloud aviation advisories for the region of the Philippine Islands. Through application of its three-dimensional material transport and diffusion models using AFGWC meteorological analysis and forecast wind fields ARAC developed extensive analysis and 12-hourly forecast ash cloud position advisories extending to 48 hours for a period of five days. The advisories consisted of ``relative`` ash cloud concentrations in ten layers (surface-5,000 feet, 5,000--10,000 feet and every 10,000 feet to 90,000 feet). The ash was represented as a log-normal size distribution of 10--200 {mu}m diameter solid particles. Size-dependent ``ashfall`` was simulated over time as the eruption clouds dispersed. Except for an internal experimental attempt to model one of the Mount Redoubt, Alaska, eruptions (12/89), ARAC had no prior experience in modeling volcanic eruption ash hazards. For the cataclysmic eruption of 15--16 June, the complex three-dimensional atmospheric structure of the region produced dramatically divergent ash cloud patterns. The large eruptions (> 7--10 km) produced ash plume clouds with strong westward transport over the South China Sea, Southeast Asia, India and beyond. The low-level eruptions (< 7 km) and quasi-steady-state venting produced a plume which generally dispersed to the north and east throughout the support period. Modeling the sequence of eruptions presented a unique challenge. Although the initial approach proved viable, further refinement is necessary and possible. A distinct need exists to quantify eruptions consistently such that ``relative`` ash concentrations relate to specific aviation hazard categories.

    Communications between civilizations within our galaxy at the present level of radio engineering is possible, although civilizations must begin to search for each other to achieve this. If an extra-terrestrial civilization possessing a technology at our level wishes to make itself known and will transmit special radio signals to do this, then it can be picked up by us at a distance of several hundreds of light years using already existing radio telescopes and specially built radio receivers. If it wishes, this civilization can also send us information without awaiting our answer.

  14. A Psychoacoustic Evaluation of Noise Signatures from Advanced Civil Transport Aircraft

    Science.gov (United States)

    Rizzi, Stephen A.; Christian, Andrew

    2016-01-01

    The NASA Environmentally Responsible Aviation project has been successful in developing and demonstrating technologies for integrated aircraft systems that can simultaneously meet aggressive goals for fuel burn, noise and emissions. Some of the resulting systems substantially differ from the familiar tube and wing designs constituting the current civil transport fleet. This study attempts to explore whether or not the effective perceived noise level metric used in the NASA noise goal accurately reflects human subject response across the range of vehicles considered. Further, it seeks to determine, in a quantitative manner, if the sounds associated with the advanced aircraft are more or less preferable to the reference vehicles beyond any differences revealed by the metric. These explorations are made through psychoacoustic tests in a controlled laboratory environment using simulated stimuli developed from auralizations of selected vehicles based on systems noise assessments.

  20. GASP- GENERAL AVIATION SYNTHESIS PROGRAM

    Science.gov (United States)

    Galloway, T. L.

    1994-01-01

    The General Aviation Synthesis Program, GASP, was developed to perform tasks generally associated with the preliminary phase of aircraft design. GASP gives the analyst the capability of performing parametric studies in a rapid manner during preliminary design efforts. During the development of GASP, emphasis was placed on small fixed-wing aircraft employing propulsion systems varying from a single piston engine with a fixed pitch propeller through twin turboprop/turbofan systems as employed in business or transport type aircraft. The program is comprised of modules representing the various technical disciplines of design, integrated into a computational flow which ensures that the interacting effects of design variables are continuously accounted for in the aircraft sizing procedures. GASP provides a useful tool for comparing configurations, assessing aircraft performance and economics, and performing tradeoff and sensitivity studies. By utilizing GASP, the impact of various aircraft requirements and design factors may be studied in a systematic manner, with benefits being measured in terms of overall aircraft performance and economics. The GASP program consists of a control module and six "technology" submodules which perform the various independent studies required in the design of general aviation or small transport type aircraft. The six technology modules include geometry, aerodynamics, propulsion, weight and balance, mission analysis, and economics. The geometry module calculates the dimensions of the synthesized aircraft components based on such input parameters as number of passengers, aspect ratio, taper ratio, sweep angles, and thickness of wing and tail surfaces. The aerodynamics module calculates the various lift and drag coefficients of the synthesized aircraft based on inputs concerning configuration geometry, flight conditions, and type of high lift device. The propulsion module determines the engine size and performance for the synthesized aircraft

    Interactive computer graphics is a fast growing area of computer application, due to such factors as substantial cost reductions in hardware, general availability of software, and expanded data communication networks. In addition to allowing faster and more meaningful input/output, computer graphics permits the use of data in graphic form to carry out parametric studies for configuration selection and for assessing the impact of advanced technologies on general aviation designs. The incorporation of interactive computer graphics into a NASA developed general aviation synthesis program is described, and the potential uses of the synthesis program in preliminary design are demonstrated.

    1997-01-01

    This report documents the progress achieved over the past 6 to 12 months on four graduate student projects conducted within the NASA-UVA Light Aerospace Alloy and Structures Technology Program. These studies were aimed specifically at light metallic alloy issues relevant to the High Speed Civil Transport. Research on Hydrogen-Enhanced Fracture of High-Strength Titanium Alloy Sheet refined successfully the high resolution R-curve method necessary to characterize initiation and growth fracture toughnesses. For solution treated and aged Low Cost Beta without hydrogen precharging, fracture is by ductile transgranular processes at 25 C, but standardized initiation toughnesses are somewhat low and crack extension is resolved at still lower K-levels. This fracture resistance is degraded substantially, by between 700 and 1000 wppm of dissolved hydrogen, and a fracture mode change is affected. The surface oxide on P-titanium alloys hinders hydrogen uptake and complicates the electrochemical introduction of low hydrogen concentrations that are critical to applications of these alloys. Ti-15-3 sheet was obtained for study during the next reporting period. Research on Mechanisms of deformation and Fracture in High-Strength Titanium Alloys is examining the microstructure and fatigue resistance of very thin sheet. Aging experiments on 0. 14 mm thick (0.0055 inch) foil show microstructural agility that may be used to enhance fatigue performance. Fatigue testing of Ti-15-3 sheet has begun. The effects of various thermo-mechanical processing regimens on mechanical properties will be examined and deformation modes identified. Research on the Effect of Texture and Precipitates on Mechanical Property Anisotropy of Al-Cu-Mg-X and Al-Cu alloys demonstrated that models predict a minor influence of stress-induced alignment of Phi, caused by the application of a tensile stress during aging, on the yield stress anisotropy of both modified AA2519 and a model Al-Cu binary alloy.

  10. The engineering options for mitigating the climate impacts of aviation.

    Science.gov (United States)

    Williams, Victoria

    2007-12-15

    Aviation is a growing contributor to climate change, with unique impacts due to the altitude of emissions. If existing traffic growth rates continue, radical engineering solutions will be required to prevent aviation becoming one of the dominant contributors to climate change. This paper reviews the engineering options for mitigating the climate impacts of aviation using aircraft and airspace technologies. These options include not only improvements in fuel efficiency, which would reduce carbon dioxide (CO2) emissions, but also measures to reduce non-CO2 impacts including the formation of persistent contrails. Integrated solutions to optimize environmental performance will require changes to airframes, engines, avionics, air traffic control systems and airspace design. While market-based measures, such as offset schemes and emissions trading, receive growing attention, this paper sets out the crucial role of engineering in the challenge to develop a 'green air traffic system'.

    2017-01-01

    The existing National Airspace System (NAS) communications capabilities are largely unsecured, are not designed for efficient use of spectrum and collectively are not capable of servicing the future needs of the NAS with the inclusion of new operators in Unmanned Aviation Systems (UAS) or On Demand Mobility (ODM). SNAC will provide a ubiquitous secure, network-based communications architecture that will provide new service capabilities and allow for the migration of current communications to SNAC over time. The necessary change in communication technologies to digital domains will allow for the adoption of security mechanisms, sharing of link technologies, large increase in spectrum utilization, new forms of resilience and redundancy and the possibly of spectrum reuse. SNAC consists of a long term open architectural approach with increasingly capable designs used to steer research and development and enable operating capabilities that run in parallel with current NAS systems.

    2013-01-01

    Based on the review of the current status and perspectives of worldwide agricultural aviation (AA) and completive analysis of the technology demand, the development strategies of aviation plant protection in China were recommended. The main restricting factors to the development of AA industry in China were pointed out, which including the imperfect policies and regulations of AA at present, lack of supporting core technologies, qualified AA professionals, understanding on AA, public support to the development of AA, and defective social service system in AA, etc. And then the countermeasures to promote the rapid and healthy development of AA in China were put forward, which including the adoption of multi-type and multi-operation models to improve the applicability of AA, increasing the capital investment to enhance the core technologies research, fortifying targeted policies to strengthen and standardize the management of AA. Finally, the demand prediction of agricultural aircraft type in China was conducted by using empiric estimation demand prediction method. The demand prediction analysis shows that the AA industry in China has not really started, and the market will dramatically increase. In the coming 15 years, the AA aircraft type in China will mainly include manned fixed-wing aircraft, manned helicopter, gasoline-powered unmanned aerial vehicle (UAV), battery-power UAV and others, and the working area to the whole cultivated area of all of these aircraft type will be about 5%by the end of 2015, 20%by 2020, 40%by 2025, 50%by 2030 respectively. It was estimated about 46.5 billion RMB of the new investment on AA aircraft type in next 15 years. With the relevant system and supporting core technologies improving continuously, the AA industry will get a healthy, orderly and rapid development in China.%农业航空是现代农业的重要组成部分和反映农业现代化水平的重要标志之一。该文在分析中国农业现代化建设中对航空植保

    Aviation is responsible for 3% of global anthropogenic CO2 emissions, but 2-14% of anthropogenic induced climate warming due to contributions from short lived climate forcers. The global civil aviation fleet is projected to double by 2026 in relation to a 2006 baseline and so will play a substantial role in future climate change. Uncertainty in the net impact of aviation on climate is largely due to uncertainty in the impacts of aviation emissions on ozone and aerosol. To study the impact of aviation emissions we use the GLOMAP-mode global aerosol microphysics model coupled to the 3-D chemical transport model TOMCAT. GLOMAP-mode has been extended to include treatment of nitrate aerosol. We include a full suite of non-CO2 aviation emissions (including NOX, SO2, HCs, BC and OC) in the model. We combined the simulated changes in ozone and aerosol with a 3D radiative transfer model to quantify the radiative effect due to aviation non-CO2 emissions. We find that aviation emissions increase O3 concentrations by up to 5.3% in the upper troposphere (UT), broadly matching previous studies. Black carbon (BC) and organic carbon (OC) concentrations increase by 26.5% and 14.6% respectively in the UT, whereas nitrate aerosol is reduced in some regions due to co-emission of NOX and SO2 In the UT, aviation emissions increase both total aerosol number as well as the concentration of particles greater than 70 nm diameter (N70). Entrainment of these particles into the free troposphere results in aviation emissions also increasing N70 in the boundary layer, causing a cooling through the first aerosol indirect effect. We explore differences in these responses compared with those simulated when using the recommended aviation emissions from CMIP5 (5th Climate Model Intercomparison Project), which only include NOX and BC emissions. Our results suggest that aviation emissions of SO2 and HCs neglected by CMIP5 produce important effects on ozone, aerosol number, and N70. We suggest CMIP5

    To meet its objective of assisting the U.S. aviation industry with the technological challenges of the future, NASA must identify research areas that have the greatest potential for improving the operation of the air transportation system. Therefore, NASA is developing the ability to evaluate the potential impact of various advanced technologies. By thoroughly understanding the economic impact of advanced aviation technologies and by evaluating how the new technologies will be used in the integrated aviation system, NASA aims to balance its aeronautical research program and help speed the introduction of high-leverage technologies. To meet these objectives, NASA is building the Aviation System Analysis Capability (ASAC). NASA envisions ASAC primarily as a process for understanding and evaluating the impact of advanced aviation technologies on the U.S. economy. ASAC consists of a diverse collection of models and databases used by analysts and other individuals from the public and private sectors brought together to work on issues of common interest to organizations in the aviation community. ASAC also will be a resource available to the aviation community to analyze; inform; and assist scientists, engineers, analysts, and program managers in their daily work. The ASAC differs from previous NASA modeling efforts in that the economic behavior of buyers and sellers in the air transportation and aviation industries is central to its conception. Commercial air carriers, in particular, are an important stakeholder in this community. Therefore, to fully evaluate the implications of advanced aviation technologies, ASAC requires a flexible financial analysis tool that credibly links the technology of flight with the financial performance of commercial air carriers. By linking technical and financial information, NASA ensures that its technology programs will continue to benefit the user community. In addition, the analysis tool must be capable of being incorporated into the

    Crew resource management (CRM) programs were developed to address team and leadership aspects of piloting modern airplanes. The goal is to reduce errors through team work. Human factors research and social, cognitive, and organizational psychology are used to develop programs tailored for individual airlines. Flight crews study accident case histories, group dynamics, and human error. Simulators provide pilots with the opportunity to solve complex flight problems. CRM in the simulator is called line-oriented flight training (LOFT). In automated cockpits CRM promotes the idea of automation as a crew member. Cultural aspects of aviation include professional, business, and national culture. The aviation CRM model has been adapted for training surgeons and operating room staff in human factors.

    Quality control measures for aviation gasoline, and some of the differences between quality control on avgas and mogas are discussed. One thing to keep in mind is that with motor gasoline you can always pull off to the side of the road. It's not so easy to do in an airplane. Consequently, there are reasons for having the tight specifications and the tight quality control measures on avgas as compared to motor gasoline.

    The rising cost of oil coupled with the need to reduce pollution and dependence on foreign suppliers has spurred great interest and activity in developing alternative aviation fuels. Although a variety of fuels have been produced that have similar properties to standard Jet A, detailed studies are required to ascertain the exact impacts of the fuels on engine operation and exhaust composition. In response to this need, NASA acquired and burned a variety of alternative aviation fuel mixtures in the Dryden Flight Research Center DC-8 to assess changes in the aircraft s CFM-56 engine performance and emission parameters relative to operation with standard JP-8. This Alternative Aviation Fuel Experiment, or AAFEX, was conducted at NASA Dryden s Aircraft Operations Facility (DAOF) in Palmdale, California, from January 19 to February 3, 2009 and specifically sought to establish fuel matrix effects on: 1) engine and exhaust gas temperatures and compressor speeds; 2) engine and auxiliary power unit (APU) gas phase and particle emissions and characteristics; and 3) volatile aerosol formation in aging exhaust plumes

    Full Text Available The research progress of heat resistance, cold resistance, electrical conductivity and damping properties of aviation silicone rubber were reviewed in this article. The heat resistance properties of silicone rubber can be enhanced by changing the molecular structure (main chain, end-group, side chain and molecular weight of the gum and adding special heat-resistance filler. The cold resistance of aviation silicone rubber can be enhanced by adjusting the side chain molecular structure of the gum and the content of different gum chain. The electrical conductivity of silicone rubber can be improved by optimizing, blending and dispersing of conductive particles. The damping property of silicone rubber can be improved by designing and synthesizing of high-molecular polysiloxane damping agent. Furthermore, the application of aviation silicone rubber used in high-low temperature seal, electrical conduction and vibration damping technology are also summarized, and the high performance (for example long-term high temperature resistance, ultralow temperature resistance, high electromagnetic shelding, long-term fatigue resistance vibration damping, quasi constant modulus and so on of special silicone rubber is the future direction of aviation silicone rubber.

  14. Taxation of United States general aviation

    Science.gov (United States)

    Sobieralski, Joseph Bernard

    General aviation in the United States has been an important part of the economy and American life. General aviation is defined as all flying excluding military and scheduled airline operations, and is utilized in many areas of our society. The majority of aircraft operations and airports in the United States are categorized as general aviation, and general aviation contributes more than one percent to the United States gross domestic product each year. Despite the many benefits of general aviation, the lead emissions from aviation gasoline consumption are of great concern. General aviation emits over half the lead emissions in the United States or over 630 tons in 2005. The other significant negative externality attributed to general aviation usage is aircraft accidents. General aviation accidents have caused over 8000 fatalities over the period 1994-2006. A recent Federal Aviation Administration proposed increase in the aviation gasoline tax from 19.4 to 70.1 cents per gallon has renewed interest in better understanding the implications of such a tax increase as well as the possible optimal rate of taxation. Few studies have examined aviation fuel elasticities and all have failed to study general aviation fuel elasticities. Chapter one fills that gap and examines the elasticity of aviation gasoline consumption in United States general aviation. Utilizing aggregate time series and dynamic panel data, the price and income elasticities of demand are estimated. The price elasticity of demand for aviation gasoline is estimated to range from -0.093 to -0.185 in the short-run and from -0.132 to -0.303 in the long-run. These results prove to be similar in magnitude to automobile gasoline elasticities and therefore tax policies could more closely mirror those of automobile tax policies. The second chapter examines the costs associated with general aviation accidents. Given the large number of general aviation operations as well as the large number of fatalities and

    Aviation emissions contribute to the radiative forcing (RF) of climate. Of importance are emissions of carbon dioxide (CO2), nitrogen oxides (NOx), aerosols and their precursors (soot and sulphate), and increased cloudiness in the form of persistent linear contrails and induced-cirrus cloudiness. Aviation operations have grown strongly over the past years and further growth is expected. This presentation will provide an updated perspective on new research and understanding of the role of aviation in climate and where uncertainties and gaps remain.

  16. METHOD IMPROVEMENT FOR DETERMINING THE TECHNICAL LEVEL OF CIVIL AIRCRAFT

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Aircraft are high-tech engineering products which are characterized by a wide range of properties including the two most important groups that respectively characterize the efficiency and technical level.Improving the aircraft efficiency is an essential factor for air transport development, but the efficiency can not be fully describe the technical system, especially in forecasting and new technology requirements development. Aircraft de- signer must evaluate the prospects of a technical solution, but it’s not always possible to calculate the efficiency accuratelyat the design stage. The operator should be able to choose the most technically-advanced aircraft available in the market inorder not to let it grow obsolete quickly. This determines the need for non-economic evaluation of technical systems that can be done by assessment of their technical level.The technical level is a general index that includes a set of technical perfection indicators. Technical perfection is reflected in terms of material and energy intensity, in terms of ergonomics, safety, etc. and is achieved as a result of origi- nal design solutions, the use of new high-strength low-density materials, the introduction of advanced technological pro-cesses, calculation methods, verification, testing, etc.There is a tight connection between the product properties and its weight, because weight is the material reflection of these properties. Therefore, improvement of the product properties usually leads to an intense increase of its weight. To deal with this phenomenon is only possible with widely using scientific and technical progress results. In accordance with this, the technical perfection can be interpreted as a major component of quality that is created without the weight increase. This approach requires investment in research and testing new technical solutions.The method was developed to determine the technical level of civil long-haul aircraft which has been modified to

    Full Text Available A practical problem in air transport is how to manage risk and safety. In recent years have been developed special technical and managerial skills to the systematic, forward looking identification and control of hazards throughout the life cycle of a project, program, or activity. Safety Management System (SMS involves identifying, evaluating, and addressing of hazards or risk. Its sole purpose is to prevent accidents. Safety risk assessment is defined as the systematic identification and evaluation of the risk posed by the complete spectrum of possible accident scenarios. Risk assessment is a tool that supports decision making and as such supports risk management. Risk management comprises the safety optimization of the system, the verification process and risk acceptance, which support airport operations. This paper proposed a quantitative methodology for the risk assessment for a civil airport, which is based on historical data of aircraft accidents, contained in the Aviation Safety Network database, from 1 January 1980 to 31 December 2010.

    Due to the characteristic of large ratio wing of civil aircrafts, gust load often composes of the severe conditions of civil aircrafts. And it must be emphasized by all countries' airworthiness regulations. Moreover, owing to the elasticity of the aircraft structure, gust disturbance induces the elastic vibrations, reduces the structure stress, produces the fatigue damage, and even promote flutter. Thus it is of very importance and significance to investigate and research in gust load and gust load alleviation technologies in flight load design. This paper gives a brief introduction of gust load theories and the relevant technologies and also puts forward a type of gust load alleviation of method direct lift control to carry out gust load alleviation of the wing.%由于民用飞机机翼具有大展弦比的特点,因此阵风载荷经常成为民用飞机飞行载荷的严重情况,是各国适航标准重点考察的飞行情况。而且,阵风干扰还会因飞机机体的自身弹性引起结构弹性振动,使飞机结构刚度降低,造成机体疲劳损伤,甚至引起颤振。因此,在民用飞机载荷设计过程中对阵风载荷及其减缓技术进行研究具有非常重要的意义。介绍了民用飞机阵风载荷的原理及相关技术,以及阵风载荷减缓技术中用直接升力控制方法来实现机翼的阵风载荷减缓。

    With the end of cold war, race for economic development and technology has replaced military competition for weighing the strength of a country. Hence Russia strategically adopts measures to divert the national defense technology partially or wholly into civil industry use. Deifnitely, Russia achieved a lot by taking measures compatible with the situation in Russia and integrating military use with civil use. However, due to absence of a macro level map, sufifcient ifnancial support and corresponding legal regime, Russia has witnessed defeats and failures during the process. China shall learn from Russia while addressing corresponding issues.%冷战结束后,经济发展和科技竞赛取代军事竞争,成为各国实力较量的焦点,俄罗斯也分阶段采取策略,将国防工业转轨生产民用产品或军民两用产品。在立足本国实际、实施军民一体化战略方面,俄罗斯的经验是值得肯定的,也取得了一定的成效。但是,由于没有宏观规划,缺乏充足的资金支持以及配套的体系化法律制度保障,其教训也是惨痛的。这些经验和教训对我国处理相关问题的启示意义很大。

    Kutz, Mary N. Hill

    Scope and method of study. The purpose of the study was to examine the personal traits, skills, practices, behaviors, background, academic, and career success patterns of selected aviation leaders in Oklahoma. A purposive sample of 18 leaders who had achieved a top-ranked position of aviation leadership in an organization or a position of influence in the community was selected for interview. The leaders chosen for interview came from a variety of aviation organizations including government, academia, military, corporate aviation, and air carrier leadership as well as community leadership (specifically those aviation personnel who were engaged in a political or civic leadership role). Findings and conclusions. This study identified no common career choices, educational, family, or other background factors exclusively responsible for leadership success of all of the participants. Some of the more significant findings were that a high percentage of the leaders held undergraduate and advanced degrees; however, success had been achieved by some who had little or no college education. Aviation technical experience was not a prerequisite for aviation leadership success in that a significant number of the participants held no airman rating and some had entered positions of aviation leadership from non-aviation related careers. All had received some positive learning experience from their family background even those backgrounds which were less than desirable. All of the participants had been involved in volunteer civic or humanitarian leadership roles, and all had received numerous honors. The most frequently identified value expressed by the leaders was honesty; the predominant management style was participative with a strong backup style for directing, the most important skills were communication and listening skills, and the most frequently mentioned characteristics of success were honesty, credibility, vision, high standards, love for aviation and fiscal

    Today carries approximately 23,000 flights over 2.2 billion passengers annually. On a global basis air travel accounts for almost 2 to 2.5 percent of the total anthropogenic Co2 emissions. Domestic civil aviation in Norway emitted 1.05 million tonnes of Co2 in 2008, according to reporting to the United Nations Framework Convention on Climate Change (UNFCCC, 2011). Emissions from international aviation from Norwegian airports in 2008 was just under 1.2 million tonnes of Co2 (National Inventory Report, 2010). Aviation is a sector that has been growing: in Norway the emissions from domestic aviation increased by 55 percent from 1990 to 2008, and also globally emissions have increased. There has been an even more powerful increase in traffic, but this increase did not been steady: The development is closely linked to the economy and the reduction is observed in periods of economic downturn. New technology and streamlining flight patterns made aircraft more energy efficient, which has helped to reduce emissions, but it has not been enough to compensate for the strong growth in traffic. If this trend continues, the total emissions from aviation increase further. In addition to Co2 consists emissions from airplanes a variety of other components that affect the climate, either directly or indirectly through chemical and physical processes in the atmosphere. This is not unique to aviation, but also apply to other sectors. The impact is complex and complicated, some mechanisms provide a cooling, others warming. Some effects are regional and have a geographic (and per day) variation in radiative forcing. Regional heterogeneous forcing can potentially change temperature and pressure distribution in the atmosphere and hence circulation patterns. The various emissions also have very different lifetimes in the atmosphere and affects the climate of the different time scales. For a number of mechanisms providing climate change are the chemical and meteorological conditions in the

  5. CIVIL SOCIETY AS A RESOURSE FOR DEVELOPMENT OF RUSSIA

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available The article is based on research on civil society in Russia conducted for the Committee of Civil Initiatives by the Centre of Political Technologies in June-July 2013. It compares the Western model of civil society with its understanding in non-Western nations. The author analyses historical evolution of the Russian society and provides assessment of its current standing. He concludes that non-governmental organisations and civil activities in Russia develop under conditions of low mutual trust among the population and between society and state. The lack of trust of governmental bodies to civil initiatives is clearly reflected in the latest legislation on “foreign agents”. The remaining unfavourable conditions are likely to continue to hinder progress of Russian civil society for the years to come. The foundation for the research created the data from surveys, in-depth interviews and group discussions.

    For the past few years, innovation in the field of General Aviation (GA) has declined. The reason for this decline has not been because of a lack of ideas, but rather a lack of funds necessary to convert these ideas into reality. NASA implemented the Small Business Innovative Research (SBIR) program in an effort to promote new technology in General Aviation. Under this program, small business with good ideas present them to NASA who reviews them and determines their value potential in the GA market. If the company's idea proves worthy, NASA subsidizes their research in three phases that include the research, testing, development, and production of their product. The purpose of my internship this summer was to use the Internet to promote the work of SBIR companies globally to prospective investors.

    Das, Kumer Pial; Dey, Asim Kumer

    2016-12-01

    Air travel is considered a safe means of transportation. But when aviation accidents do occur they often result in fatalities. Fortunately, the most extreme accidents occur rarely. However, 2014 was the deadliest year in the past decade causing 111 plane crashes, and among them worst four crashes cause 298, 239, 162 and 116 deaths. In this study, we want to assess the risk of the catastrophic aviation accidents by studying historical aviation accidents. Applying a generalized Pareto model we predict the maximum fatalities from an aviation accident in future. The fitted model is compared with some of its competitive models. The uncertainty in the inferences are quantified using simulated aviation accident series, generated by bootstrap resampling and Monte Carlo simulations.

    Full Text Available  To say that Indonesia is an enigma in air transport is an understatement.  On the one hand,  the  demand for air transport in Indonesia is higher in proportion to its GDP per capita.  Its economy can be expected to grow 6% to 10% annually. A single aviation market could add another 6% to 10% growth in sheer demand.  It is one of the wealthiest countries in the world, being the 16th richest country currently, and, according to an Airbus forecast,   will be the 7th richest in 2030.  Yet its airports are badly in need of expansion, its infrastructure is bursting at its seems, and above all, its airlines are strongly resisting liberalization of air transport in the region for fear of being wiped out by stronger contenders in the region.  Against this backdrop, it is incontrovertible that Indonesia's civil aviation is intrinsically linked to regional and global considerations.  Indonesia's archipelagic topography makes its people heavily reliant on safe, regular and reliable air services that may connect them not only internally but also to the outside world.A single aviation market in the ASEAN region will bring both benefits to Indonesia and challengers to its air transport sector. This article discusses the economic and regulatory challenges that Indonesia faces with the coming into effect of the ASEAN Single Aviation market in 2015.

  8. A Formal Messaging Notation for Alaskan Aviation Data

    Rios, Joseph L.

    2015-01-01

    Data exchange is an increasingly important aspect of the National Airspace System. While many data communication channels have become more capable of sending and receiving data at higher throughput rates, there is still a need to use communication channels efficiently with limited throughput. The limitation can be based on technological issues, financial considerations, or both. This paper provides a complete description of several important aviation weather data in Abstract Syntax Notation format. By doing so, data providers can take advantage of Abstract Syntax Notation's ability to encode data in a highly compressed format. When data such as pilot weather reports, surface weather observations, and various weather predictions are compressed in such a manner, it allows for the efficient use of throughput-limited communication channels. This paper provides details on the Abstract Syntax Notation One (ASN.1) implementation for Alaskan aviation data, and demonstrates its use on real-world aviation weather data samples as Alaska has sparse terrestrial data infrastructure and data are often sent via relatively costly satellite channels.

    Industry associations have set goals to reduce greenhouse gas (GHG) emissions and increase fuel efficiency. One focal area for reducing GHG emissions is in the use of aviation biofuel. This study examines assumptions under which the United States could see large production in aviation biofuel. Our results suggest that a high penetration (6 billion gallons) of aviation biofuels by 2030 could be possible, but factors around policy design (in the absence of high oil prices) contribute to the timing and magnitude of aviation biofuels production: 1) Incentives targeted towards jet fuel production such as financial incentives (e.g., producer tax credit, carbon tax) can be sufficient; 2) Investment in pre-commercial cellulosic technologies is needed to reduce the cost of production through learning-by-doing; 3) Reduction of investment risk through loan guarantees may allow production to ramp up more quickly through accelerating industry learning. In cases with high levels of incentives and investment in aviation biofuels, there could be a 25 percent reduction in overall GHG emissions from the aviation sector.

    Full Text Available The article elaborates the proposals to improve the systems for monitoring performance of the equipment at the enterprises of aviation instrument. The relevance of the study due to the fact that the aviation instrument-making industry of the Russian Federation can play a role as a key factor in enhancing the competitiveness of the national economy. Currently, the global aviation market is fairly saturated, it competition is not between individual companies and between the aviation powers. The role of an efficient industrial production is largely dependent on the amount, structure, technical condition and the level of utilization of fixed assets. Specificity of high-tech high-tech production presupposes the existence of a specific fleet of expensive and unique equipment; a high degree of novelty products, single or small-scale type of production that determines the high cost of production of a unit of production; high demands on the staff . The paper noted that the production capacity is an essential tool for production planning process, which allows to determine the optimal work shifts Park main technological equipment and production program to justify the enterprises of sphere of aviation instrument. On the basis of the modification of OEE method, a stochastic model is proposed, which allows to display the efficiency of the productive capacity of the high-tech enterprises of sphere of aviation instrument in the form of multi-dimensional size and much more accurately identify the relationship between its elements.

  11. Flight plan: taking responsibility for aviation emissions

    2007-07-01

    Aviation emissions make up less than 2 per cent of the world total, but are rising fast. These environmental costs must be balanced with development gains, however: air travel can hugely benefit poor countries' economies. The good news is that much can be done to curb emissions while keeping those benefits on board. Workable tools and guidelines for passengers, travel providers, government and airlines are waiting in the wings. A vital area for improvement is the way emissions are reported and calculated. Airlines, travel providers and carbon companies currently report emissions using a hotchpotch of methods, all producing varying results. Basing reports on fuel usage will make standardised ecolabelling possible. With an informed choice, passengers can buy tickets strategically and so encourage airlines to use more efficient technology. Airports can integrate ways of limiting emissions into their daily operations, while governments can invest in better air traffic control. Collective responsibility — and action — could make flying a much more sustainable means of travel.

    Full Text Available Avionics is a very crucial and important technology, not only for civil/military aircraft but also for missiles, spacecraft, micro air vehicles (MAVs and unmanned aerial vehicles (UAVs. Even for ground-based vehicles and underwater vehicles (UWVs, avionics is a very important segment of their successful operation and mission accomplishment. The advances in many related and supporting technologies, especially digital electronics, embedded systems, embedded algorithms/software, mobile technology, sensors and instrumentation, computer (network-communication, and realtime operations and simulation, have given a great impetus to the field of avionics. Here, for the sake of encompassing many other applications as mentioned above, the term is used in an expanded sense: Aerospace Avionics (AA, although it is popularly known as Aviation Electronics (or Avionics. However, use of this technology is not limited to aircraft, and hence, we  can incorporate all the three types-ground, land, and underwater vehicles-under the term avionics.Defence Science Journal, 2011, 61(4, pp.287-288, DOI:http://dx.doi.org/10.14429/dsj.61.1122

  14. PLANNING THE WORK OF AVIATION UNITS USING PROJECT MANAGEMENT TOOLS

    Directory of Open Access Journals (Sweden)

    Dmitry Valerievich Bogomolov

    2017-01-01

    Full Text Available The article deals with the problematic issues of planning the work of aviation units and offers one of the possible variants of their solutions by means of project management tools implementation in aviation units.As a key concept in the theory of planning, the author proposes introducing the concept of a project as a complex, non-repeating one-time action, limited in time, budget, resources and in clear guidance throughout the process, followingthe customer requirements. In aviation engineering service work, this also includes such works as operational preparationstypes, routine maintenance, aviation technology improvements, military repair etc.The use of network models can also easily specify the sequence of some of the actions (events, to make process flow charts and organizational charts.The main advantage of linear graphs is their clarity and simplicity. Linear graphs make it possible to optimize the work on a variety of criteria, including the equability of labor force, machinery, building materials, etc. At the same time,the main drawback of linear graphs is that they are difficult to correct in case of non-compliance with the deadlines or a change in their arrangement. These drawbacks are eliminated by a different form of scheduling - network charts.The scheme of planning the work of units using project management tools is given. To carry out the scheme theauthor proposes to use modern tools of project management, which allow to structure the process of maintenance activities through its decomposition into phases, tasks and subtasks, then to identify critical path tasks, construct the chart of imple- mentation. The process model as a project allows to make the prognostic analysis and to improve the process according to it, for what a number of modern software packages that automate the functions of planning and planned types of work schedule control.

  15. Diffusing aviation innovations in a hospital in The Netherlands.

    Many authors have advocated the diffusion of innovations from other high-risk industries into health care to improve safety. The aviation industry is comparable to health care because of its similarities in (a) the use of technology, (b) the requirement of highly specialized professional teams, and (c) the existence of risk and uncertainties. For almost 20 years, The Rotterdam Eye Hospital (Rotterdam, the Netherlands) has been engaged in diffusing several innovations adapted from aviation. A case-study methodology was used to assess the application of innovations in the hospital, with a focus on the context and the detailed mechanism for each innovation. Data on hospital performance outcomes were abstracted from the hospital information data management system, quality and safety reports, and the incident reporting system. Information on the innovations was obtained from a document search; observations; and semistructured, face-to-face interviews. Aviation industry-based innovations diffused into patient care processes were as follows: patient planning and booking system, taxi service/valet parking, risk analysis (as applied to wrong-site surgery), time-out procedure (also for wrong-site surgery), Crew Resource Management training, and black box. Observations indicated that the innovations had a positive effect on quality and safety in the hospital: Waiting times were reduced, work processes became more standardized, the number of wrong-site surgeries decreased, and awareness of patient safety was heightened. A near-20-year experience with aviation-based innovation suggests that hospitals start with relatively simple innovations and use a systematic approach toward the goal of improving safety.

  2. Developing Quantum Dot Phosphor-Based Light-Emitting Diodes for Aviation Lighting Applications

    Directory of Open Access Journals (Sweden)

    Fengbing Wu

    2012-01-01

    Full Text Available We have investigated the feasibility of employing quantum dot (QD phosphor-based light-emitting diodes (LEDs in aviation applications that request Night Vision Imaging Systems (NVIS compliance. Our studies suggest that the emerging QD phosphor-based LED technology could potentially be superior to conventional aviation lighting technology by virtue of the marriage of tight spectral control and broad wavelength tunability. This largely arises from the fact that the optical properties of semiconductor nanocrystal QDs can be tailored by varying the nanocrystal size without any compositional changes. It is envisioned that the QD phosphor-based LEDs hold great potentials in cockpit illumination, back light sources of monitor screens, as well as the LED indicator lights of aviation panels.

  3. Single-Lever Power Control for General Aviation Aircraft Promises Improved Efficiency and Simplified Pilot Controls

    Science.gov (United States)

    Musgrave, Jeffrey L.

    1997-01-01

    General aviation research is leading to major advances in internal combustion engine control systems for single-engine, single-pilot aircraft. These advances promise to increase engine performance and fuel efficiency while substantially reducing pilot workload and increasing flight safety. One such advance is a single-lever power control (SLPC) system, a welcome departure from older, less user-friendly, multilever engine control systems. The benefits of using single-lever power controls for general aviation aircraft are improved flight safety through advanced engine diagnostics, simplified powerplant operations, increased time between overhauls, and cost-effective technology (extends fuel burn and reduces overhaul costs). The single-lever concept has proven to be so effective in preliminary studies that general aviation manufacturers are making plans to retrofit current aircraft with the technology and are incorporating it in designs for future aircraft.

  12. Re-thinking civil disobedience

    Directory of Open Access Journals (Sweden)

    Theresa Züger

    2013-11-01

    Full Text Available This article points out a struggle of today’s societies with the traditional concepts of civil disobedience and stresses the need for reevaluation of the concept of civil disobedience for policy making and public discourse. Starting with a minimal definition of civil disobedience, the article introduces Hannah Arendt’s approach for a legitimisation of civil disobedience and discusses her ideas for digital actions, which are increasingly framed as digital forms of civil disobedience. Addressing WikiLeaks as an example of digital civil disobedience, the author problematises the internal secrecy of WikiLeaks and the focus on Julian Assange as a single decision-maker. Both aspects challenge Arendt’s understanding of legitimate civil disobedience. Even though traditional criteria of civil disobedience need to be revisited in the digital age, organisations or disobedience actors might themselves in their actions be well-advised to comply with the principles they fight for.

    2011-01-01

    The Civil Partnership Act 2004, which came into force in December 2005 allowing same-sex couples in the UK to register their relationship for the first time, celebrated its fifth anniversary in December 2010. This article examines civil partnership in England and Wales, five years on from its introduction. The characteristics of those forming civil partnerships between 2005 and 2010 including age, sex and previous marital/civil partnership status are examined. These are then compared with the characteristics of those marrying over the same period. Further comparisons are also made between civil partnership dissolutions and divorce. The article presents estimates of the number of people currently in civil partnerships and children of civil partners. Finally the article examines attitudes towards same-sex and civil partner couples both in the UK and in other countries across Europe.

  14. Using random forests to diagnose aviation turbulence

    OpenAIRE

    2013-01-01

    Atmospheric turbulence poses a significant hazard to aviation, with severe encounters costing airlines millions of dollars per year in compensation, aircraft damage, and delays due to required post-event inspections and repairs. Moreover, attempts to avoid turbulent airspace cause flight delays and en route deviations that increase air traffic controller workload, disrupt schedules of air crews and passengers and use extra fuel. For these reasons, the Federal Aviation Administration and the N...

    Currently it is not unusual for general aviation pilots in the United States to continue to fly beyond the age of 70, even into their 80s and 90s. Pilots have regular examinations according to protocols which do not specify special or additional requirements for pilots over 70 yr of age. Additionally, the third class medical reforms passed by the U.S. Senate on 15 July 2016 could potentially result in even less stringent medical certification requirements for general aviation pilots. Accident rates, medical parameters, autopsy findings, and toxicological findings from the U.S. National Transportation Safety Board (NTSB) general aviation (GA) accident database were analyzed to assess potential risk factors with accident outcomes. During 2003-2012, there were 114 (113 men, 1 woman) general aviation fatal accidents involving pilots ages 70 to 92 yr. A combination of 3 or more drugs were found in 13 (13%) of deceased pilots. The most frequent drugs were first generation antihistamines and antidepressants represented the next highest proportion of possible performance-affecting medications. This study indicates that there are critical medical factors that may contribute to fatal accidents among elderly pilots. Polypharmacy use should be taken into consideration, especially during periodic health examinations and fatal aviation investigations involving elderly pilots.Vuorio A, Asmayawati S, Budowle B, Griffiths R, Strandberg T, Kuoppala J, Sajantila A.

    In 2004, the global commercial aircraft fleet included more than 13,000 aircraft flying over 30 billion km, burning more than 100 million tons of fuel. All this activity incurs substantial amounts of fossil-fuel combustion products at the cruise altitude within the upper troposphere and lower stratosphere that could potentially affect the atmospheric composition and climate. These emissions; such as CO, CO2, PM, NOx, SOx, are not distributed uniformly over the earth, so understanding the temporal and spatial distributions is an important component for modeling aviation climate impacts. Previous studies for specific years have shown that nearly all activity occurs in the northern hemisphere, and most is within mid-latitudes. Simply scaling older data by the annual global industry growth of 3-5 percent may provide emission trends which are not representative of geographically varying growth in aviation sector that has been noted over the past years. India, for example, increased its domestic aviation activity recently by 46 percent in one year. Therefore, it is important that aircraft emissions are best characterized and represented in the atmospheric models for impacts analysis. Data containing all global commercial flights for 2004 was computed using the Federal Aviation Administration's Aviation Environmental Design Tool (AEDT) and provided by the Volpe National Transportation Systems Center. The following is a summary of this data which illustrates the global aviation footprint for 2004, and provides temporal and three-dimensional spatial distribution statistics of several emissions constituents.

  18. Initial Cognitive Performance Predicts Longitudinal Aviator Performance

    Objectives. The goal of the study was to improve prediction of longitudinal flight simulator performance by studying cognitive factors that may moderate the influence of chronological age. Method. We examined age-related change in aviation performance in aircraft pilots in relation to baseline cognitive ability measures and aviation expertise. Participants were aircraft pilots (N = 276) aged 40–77.9. Flight simulator performance and cognition were tested yearly; there were an average of 4.3 (± 2.7; range 1–13) data points per participant. Each participant was classified into one of the three levels of aviation expertise based on Federal Aviation Administration pilot proficiency ratings: least, moderate, or high expertise. Results. Addition of measures of cognitive processing speed and executive function to a model of age-related change in aviation performance significantly improved the model. Processing speed and executive function performance interacted such that the slowest rate of decline in flight simulator performance was found in aviators with the highest scores on tests of these abilities. Expertise was beneficial to pilots across the age range studied; however, expertise did not show evidence of reducing the effect of age. Discussion. These data suggest that longitudinal performance on an important real-world activity can be predicted by initial assessment of relevant cognitive abilities. PMID:21586627

    2000-01-01

    Weather is one of the major causes of aviation accidents. General aviation (GA) flights account for 92% of all the aviation accidents, In spite of all the official and unofficial sources of weather visualization tools available to pilots, there is an urgent need for visualizing several weather related data tailored for general aviation pilots. Our system, Aviation Weather Data Visualization Environment AWE), presents graphical displays of meteorological observations, terminal area forecasts, and winds aloft forecasts onto a cartographic grid specific to the pilot's area of interest. Decisions regarding the graphical display and design are made based on careful consideration of user needs. Integral visual display of these elements of weather reports is designed for the use of GA pilots as a weather briefing and route selection tool. AWE provides linking of the weather information to the flight's path and schedule. The pilot can interact with the system to obtain aviation-specific weather for the entire area or for his specific route to explore what-if scenarios and make "go/no-go" decisions. The system, as evaluated by some pilots at NASA Ames Research Center, was found to be useful.

  20. Nobody seems to speak English here today: Enhancing assessment and training in aviation English

    Directory of Open Access Journals (Sweden)

    Dan Douglas

    2014-07-01

    Full Text Available In 2003 the International Civil Aviation Organization (ICAO strengthened the provisions that English be made available for international radiotelephony communication. ICAO also developed standards for English proficiency for international pilots and air traffic controllers. However, these standards are applied variably from country to country and in no country are native speakers of English tested for their ability to employ what has been termed "interactional competence" when using English for intercultural communication. Problems with this situation are reviewed and suggestions made for improving English assessment and training.
