  2. Radiation exposure from civil aviation

    International Nuclear Information System (INIS)

    The question as to whether civil air crews and frequent air passengers ought to be classified among the group of occupationally exposed persons has in principle been decided by the recommendations adopted by the ICRP, the competent bodies of the EU, and national authorities. Measurements for more information on the radiation fields involved are planned. The German Radiation Protection Office (BfS) recently published a statement on dose commitments, assuming a maximum annual dose of approx. 8 mSv in addition to the mean value already determined. Legal provisions, which ought to be adopted also on EU level since civil aviation is a transboundary traffic system, have yet to come. (orig./HP)

  7. Risk assessment techniques for civil aviation security

    International Nuclear Information System (INIS)

    Following the 9/11 terrorists attacks in New York a strong economical effort was made to improve and adapt aviation security, both in infrastructures as in airplanes. National and international guidelines were promptly developed with the objective of creating a security management system able to supervise the identification of risks and the definition and optimization of control measures. Risk assessment techniques are thus crucial in the above process, since an incorrect risk identification and quantification can strongly affect both the security level as the investments needed to reach it. The paper proposes a set of methodologies to qualitatively and quantitatively assess the risk in the security of civil aviation and the risk assessment process based on the threats, criticality and vulnerabilities concepts, highlighting their correlation in determining the level of risk. RAMS techniques are applied to the airport security system in order to analyze the protection equipment for critical facilities located in air-side, allowing also the estimation of the importance of the security improving measures vs. their effectiveness.

  13. Evolution of civil aeromedical helicopter aviation.

    Science.gov (United States)

    Meier, D R; Samper, E R

    1989-07-01

    The rapid increase in the use of helicopters for hospital transport during the 1980s is the culmination of several hundred years of military medical innovation. Mass battefield casualties spurred both technologic and medical changes necessary for today's sophisticated helicopter systems in use worldwide, particularly in the United States. The Napoleonic Era and the American Civil War provided the framework for the evolution of today's state-of-the-art emergency medical techniques. The use of airplanes to evacuate the wounded eventually led to using helicopters for rescue missions in World War II. The combat experiences of the United States in Korea, the British in Malaya, and the French in Indochina proved that rotary-wing aircraft were invaluable in reducing battlefield death rates. Any skepticism about the efficacy of helicopter medical evacuation was erased during the Vietnam conflict. As an integral part of the modern battlefield, these specialized aircraft became a necessity. The observations and experience of American servicemen and medical personnel in Vietnam established the foundation for the acceptance of helicopter transport in modern hospital systems. PMID:2665130

    Full Text Available Polish accession to the EU and which consequently adapt Polish law to EU standards drew attention to the aviation community on the need for training and improvement of the quality of work people employed at the airport. Similarly, the subject was developed in the protection of civil aviation. Here, however, the direct stimulus for the formation of all kinds of regulations were the events in the USA 11.09.2001 r. It was then that apart from the obvious need to introduce more restrictive rules related to the security control of passengers and their luggage, it was also noted for staff training, their skills, threat detection and appropriate response to all types of custom passenger behavior. Then also placed special emphasis on quality control work, which is reflected in even the National Training Programme and the National Quality Control Programme, which are designed, on the one hand, professional prepare of the screeners for the implementation of the their statutory tasks, on the other hand, has created a tool to supervise the quality of the work done by this group of workers. Awareness of the human factor as an element that could significantly affect the level of airport security makes this factor is particularly treated in the protection of civil aviation. The consequences of human error, resulting from an act of conscious or unintentional, may in fact be catastrophic for the airport, the carrier and passengers.

  6. 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.

    2012-06-01

    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.

  8. EU Accession and Civil Aviation Regimes: Malta and Cyprus as a Case Study

    Science.gov (United States)

    Papatheodorou, Andreas; Busuttil, Louis

    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

  14. Civil aviation management during explosive volcanic eruptions: A survey on the stakeholders' perspective on the use of tephra dispersal models

    Science.gov (United States)

    Scaini, Chiara; Bolić, Tatjana; Folch, Arnau; Castelli, Lorenzo

    2015-03-01

    Impacts of explosive volcanic eruptions on civil aviation were reconsidered after the 2010 Eyjafjallajökull eruption in Iceland, which caused unprecedented disruptions of air traffic operations in Europe. During and after the aviation breakdown of April-May 2010, communication between the involved stakeholders was recognized as a major concern. Due to the complexity and multidisciplinary nature of the topic, a great number of actors are involved, which often have little interaction outside these exceptional events. In this work, we aim at identifying the relationships between the stakeholders involved in aviation management during eruptions, as well as their needs and priorities. We perform an anonymous on-line survey, focused mainly on the use of tephra dispersal models for civil aviation purposes. We collect feedback on recent developments including our current impact assessment research, which produced a GIS-based software tool to estimate impacts on aviation based on tephra dispersal forecasts. Answers allow identifying stakeholders' requirements on ash dispersal forecasts and their use for aviation management purposes. We underline the main differences between three homogeneous groups (aviation managers and employees, modellers and field scientists, other stakeholders) and identify main end-user requirements for developing tools similar to ours. This work provides useful insights for the development of tools to support aviation stakeholders during volcanic eruptions.

  15. 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.

    2015-01-01

    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

  17. Radar Tracking with an Interacting Multiple Model and Probabilistic Data Association Filter for Civil Aviation Applications

    Directory of Open Access Journals (Sweden)

    Shau-Shiun Jan

    2013-05-01

    Full Text Available The current trend of the civil aviation technology is to modernize the legacy air traffic control (ATC system that is mainly supported by many ground based navigation aids to be the new air traffic management (ATM system that is enabled by global positioning system (GPS technology. Due to the low receiving power of GPS signal, it is a major concern to aviation authorities that the operation of the ATM system might experience service interruption when the GPS signal is jammed by either intentional or unintentional radio-frequency interference. To maintain the normal operation of the ATM system during the period of GPS outage, the use of the current radar system is proposed in this paper. However, the tracking performance of the current radar system could not meet the required performance of the ATM system, and an enhanced tracking algorithm, the interacting multiple model and probabilistic data association filter (IMMPDAF, is therefore developed to support the navigation and surveillance services of the ATM system. The conventional radar tracking algorithm, the nearest neighbor Kalman filter (NNKF, is used as the baseline to evaluate the proposed radar tracking algorithm, and the real flight data is used to validate the IMMPDAF algorithm. As shown in the results, the proposed IMMPDAF algorithm could enhance the tracking performance of the current aviation radar system and meets the required performance of the new ATM system. Thus, the current radar system with the IMMPDAF algorithm could be used as an alternative system to continue aviation navigation and surveillance services of the ATM system during GPS outage periods.

    Mayo, L. H.

    1971-01-01

    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.

    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

    . 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.

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

    Science.gov (United States)

    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

    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

    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. PMID:22858009

    2012-01-01

    As a result of the serious consequences of the 2010 Eyjafjallajökull eruption (Iceland) on civil aviation, 52 volcanologists, meteorologists, atmospheric dispersion modellers and space and ground-based monitoring specialists from 12 different countries (including representatives from 6 Volcanic Ash Advisory Centres and related institutions) gathered to discuss the needs of the ash dispersal modelling community, investigate new data-acquisition strategies (i.e. quantitative measurements and observations) and discuss how to improve communication between the research community and institutions with an operational mandate. Based on a dedicated benchmark exercise and on 3 days of in-depth discussion, recommendations have been made for future model improvements, new strategies of ash cloud forecasting, multidisciplinary data acquisition and more efficient communication between different communities. Issues addressed in the workshop include ash dispersal modelling, uncertainty, ensemble forecasting, combining dispersal models and observations, sensitivity analysis, model variability, data acquisition, pre-eruption forecasting, first simulation and data assimilation, research priorities and new communication strategies to improve information flow and operational routines. As a main conclusion, model developers, meteorologists, volcanologists and stakeholders need to work closely together to develop new and improved strategies for ash dispersal forecasting and, in particular, to: (1) improve the definition of the source term, (2) design models and forecasting strategies that can better characterize uncertainties, (3) explore and identify the best ensemble strategies that can be adapted to ash dispersal forecasting, (4) identify optimized strategies for the combination of models and observations and (5) implement new critical operational strategies.

    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

    With the rapid development of China’s civil aviation, aircraft noise has become a rigorous problem. International Civil Aviation Organization (ICAO) is developing a much more stringent noise standard, and now Chapters 4-7 EPN dB program has been implemented. This article studies the impact of the Chapters 4-7 EPN dB program on Chinese fleet. In order to make China’s civil aviation manufacturing industry to meet the highly stringent standard, it is necessary to adjust the structure of Chinese fleet. Namely, the number of aircrafts with different seat classes needs to be adjusted to meet seat demand. Some aircrafts which can not meet the stringent requirement of ICAO standard in noise control must be improved in their structures.%随着我国民航事业的发展,飞机噪声问题日益突出。国际民航组织正在制定更为严格的噪声标准,如今已经实施了第4章-7的方案。为了能够满足更高要求的标准,需要对中国机队的结构进行调整,即通过调整不同的座位等级的飞机数量来满足机队的需求。一些满足不了高的噪声严格度要求的飞机项目,就必须采取措施,例如改进飞机结构以降低噪声。研究第4章-7方案对中国机队的影响是有益的。

    Aviation is integral to the global economy but it is also one of the main obstacles to environmentally sustainable development. It is one of the world's fastest growing - and most polluting - industries. What can be done to retain the economic and other benefits it brings, without the associated pollution, noise, congestion and loss of countryside? In this volume, industry, policy and research experts examine how to address the problems, and what it would take to achieve genuinely sustainable aviation - looking at technological, policy and demand-management options. Without far-reaching changes the problems caused by aviation can only multiply and worsen. This work seeks to take an important step in diagnosing the problems and in pointing towards their 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.

    Throughout the 20th Century, NASA has defined the forefront of aeronautical technology, and the aviation industry owes much of its prosperity to this knowledge and technology. In recent decades, centralized aeronautics has become a mature discipline, which raises questions concerning the future aviation innovation frontiers. Three transformational aviation capabilities, bounded together by the development of a Free Flight airspace management system, have the potential to transform 21st Century society as profoundly as civil aviation transformed the 20th Century. These mobility breakthroughs will re-establish environmental sustainable centralized aviation, while opening up latent markets for civil distributed sensing and on-demand rural and regional transportation. Of these three transformations, on-demand aviation has the potential to have the largest market and productivity improvement to society. The information system revolution over the past 20 years shows that vehicles lead, and the interconnecting infrastructure to make them more effective follows; that is, unless on-demand aircraft are pioneered, a distributed Air Traffic Control system will likely never be established. There is no single technology long-pole that will enable on-demand vehicle solutions. However, fully digital aircraft that include electric propulsion has the potential to be a multi-disciplinary initiator of solid state technologies that can provide order of magnitude improvements in the ease of use, safety/reliability, community and environmental friendliness, and affordability.

The contribution under consideration reports on an extension of this model to the aviation, so that current and differentiated emission results can be produced in future in order to meet the requirements of the reporting. The updated emission values are transferred to the Central System of Emissions (CSE).

    1988-01-01

    The fundamental principles of human-factors (HF) analysis for aviation applications are examined in a collection of reviews by leading experts, with an emphasis on recent developments. The aim is to provide information and guidance to the aviation community outside the HF field itself. Topics addressed include the systems approach to HF, system safety considerations, the human senses in flight, information processing, aviation workloads, group interaction and crew performance, flight training and simulation, human error in aviation operations, and aircrew fatigue and circadian rhythms. Also discussed are pilot control; aviation displays; cockpit automation; HF aspects of software interfaces; the design and integration of cockpit-crew systems; and HF issues for airline pilots, general aviation, helicopters, and ATC.

  20. 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.

    2008-04-01

    Full Text Available “Aviation English” is not only confined to pilots and air traffic controllers (ATC, it also refers to English on general terms in aeronautical and/or aviation universities. 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.

    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.

  19. Entrepreneurship within General Aviation

    Science.gov (United States)

    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.

  1. Radiation protection of aviation personnel at exposure by cosmic radiation

    International Nuclear Information System (INIS)

    For determination of radiation dose of aviation personnel we used the software EPCARD (European Program Package for the Calculation of Aviation Route Doses) developed by National Research Center for Environmental Health - Institute of Radiation Protection (Neuherberg, Germany) and the software CARI 6, developed by the FAA's Civil Aerospace Medical Institute (USA). Both codes are accomplished by the Joint Aviation Authorities. Experimental measurement and estimation of radiation doses of aviation personnel at exposure by cosmic radiation were realised in the period of lowered solar activity. All-year effective dose of pilots, which worked off at least 11 months exceeds the value 1 mSv in 2007. The mean all-year effective dose of member of aviation personnel at exposure by cosmic radiation is 2.5 mSv and maximal all-year effective dose, which we measured in 2007 was 4 mSv. We assumed that in the period of increased solar activity the all-year effective doses may by higher

  2. International aviation emissions to 2025. Can emissions be stabilised without restricting demand?

    International Nuclear Information System (INIS)

    International aviation is growing rapidly, resulting in rising aviation greenhouse gas emissions. Concerns about the growth trajectory of the industry and emissions have led to calls for market measures such as emissions trading and carbon levies to be introduced to restrict demand and prompt innovation. This paper provides an overview of the science on aviation's contribution to climate change, analyses key trends in the industry since 1990, projects international civil aviation emissions to 2025 and analyses the emission intensity improvements that are necessary to offset rising international demand. The findings suggest international aviation carbon dioxide (CO2) emissions will increase by more than 110 per cent between 2005 and 2025 (from 416 Mt to between 876 and 1013 Mt) and that it is unlikely emissions could be stabilised at levels consistent with risk averse climate targets without restricting demand.

    Aircrew fatigue is a major contributor to operational errors in civil and military aviation. Objective detection of pilot fatigue is thus critical to prevent aviation catastrophes. Previous work has linked fatigue to changes in oculomotor dynamics, but few studies have studied this relationship in critical safety environments. Here we measured the eye movements of US Marine Corps combat helicopter pilots before and after simulated flight missions of different durations.We found a decrease in saccadic velocities after long simulated flights compared to short simulated flights. These results suggest that saccadic velocity could serve as a biomarker of aviator fatigue. PMID:26597121

  6. Methanol commercial aviation fuel

    International Nuclear Information System (INIS)

    Southern California's heavy reliance on petroleum-fueled transportation has resulted in significant air pollution problems within the south Coast Air Basin (Basin) which stem directly from this near total dependence on fossil fuels. To deal with this pressing issue, recently enacted state legislation has proposed mandatory introduction of clean alternative fuels into ground transportation fleets operating within this area. The commercial air transportation sector, however, also exerts a significant impact on regional air quality which may exceed emission gains achieved in the ground transportation sector. This paper addresses the potential, through the implementation of methanol as a commercial aviation fuel, to improve regional air quality within the Basin and the need to flight test and demonstrate methanol as an environmentally preferable fuel in aircraft turbine engines

  13. Safer Aviation Materials Tested

    Science.gov (United States)

    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

    automobiles. ?? Community Noise: Hub and smaller GA airports are facing increasing noise restrictions, and while commercial airliners have dramatically decreased their community noise footprint over the past 30 years, GA aircraft noise has essentially remained same, and moreover, is located in closer proximity to neighborhoods and businesses. ?? 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

    During the development of their work, the aviator pilots are exposed at high levels of natural radiation of bottom caused mainly by the cosmic radiation of galactic origin and lot. For such reason, the Metropolitan Autonomous University (UAM) and the Union Association of Aviator Pilots (ASPA), subscribed an agreement with the purpose of to measure the doses of ionizing radiation received by the aviator pilots of diverse air companies that man different types of airships and to determine if these doses surpass the one limit of 0.11 mSv/h settled down by the IAEA for the public in general; and if therefore, these workers should be considered as personnel occupationally exposed. In this work the obtained results when measuring the absorbed dose received by Mexican civil aviator pilots during the development of their work, using thermoluminescent dosemeters of LiF:Mg,Cu,P + Ptfe of national production are presented. The obtained results during the years of 2001 and 2002 show that the monthly doses received by the pilots surpass the one it limits established for the public in general, for what they should be considered as personnel occupationally exposed.

    2007-01-01

    Interventions or technologies developed to improve aviation safety often focus on specific causes or accident categories. Evaluation of the potential effectiveness of those interventions is dependent upon mapping the historical aviation accidents into those same accident categories. To that end, the United States civil aviation accidents occurring between 1988 and 2004 (n=26,117) were assigned accident categories based upon the taxonomy developed by the CAST/ICAO Common Taxonomy Team (CICTT). Results are presented separately for four main categories of flight rules: Part 121 (large commercial air carriers), Scheduled Part 135 (commuter airlines), Non-Scheduled Part 135 (on-demand air taxi) and Part 91 (general aviation). Injuries and aircraft damage are summarized by year and by accident category.

  10. Distributed Aviation Concepts and Technologies

    Science.gov (United States)

    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

  12. Emissions trading in international aviation. Possible design options for an emissions trading scheme and their impact on climate change and the aviation industry

    International Nuclear Information System (INIS)

    According to the Intergovernmental Panel on Climate Change (IPCC), the contribution of aviation to global warm-ing was 3.5 % in 1992. Considering the average growth rate of 4 % per year, the share might be more than doubled by the end of the first commitment period of the Kyoto Protocol (2012). However, due to difficulties in allocating emissions from international aviation to individual countries, these emissions are exempt from commitments under the Kyoto Protocol, although in Article 2.2 the Parties to the Protocol are obliged to stabilize and reduce greenhouse gas emissions from international aviation. To comply with this obligation, the introduction of emissions trading in international aviation is being discussed within the International Civil Aviation Organisation (ICAO). This paper analyses the design options of such an emissions trading scheme and its impact on climate change and the aviation industry. Among other matters, it discusses issues such as open and closed emissions trading schemes, coverage of gases, initial allocation of allowances and possible caps for the aviation industry. It is based on a re-search project that has been carried out on behalf of the German Federal Environmental Agency. The paper reveals that despite complex tropospheric and stratospheric interactions, as well as allocation problems, there are adequate structural options for the design of an emissions trading scheme. Given an adequate structure, emissions trading offers a great incentive to optimise flight routes not only according to economic but also to climatic factors. Consequently, the system would effectively reduce the contribution of aviation to climate change

    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. PMID:21633764

  1. Greenhouse gas emissions from international aviation and allocation options

    International Nuclear Information System (INIS)

    Annex I shall pursue limitation or reduction of emissions of greenhouse gases not controlled by the Montreal Protocol from international aviation and marine bunker fuels, working through the International Civil Aviation Organisation (ICAO) and the International Maritime Organisation (IMO), respectively' (UNFCCC 1997). As yet, the ICAO Assembly has not agreed upon new initiatives specifically aimed at reducing greenhouse gas emissions, but ICAOs Committee on Aviation Environmental Protection (CAEP) is investigating several options. Some of these options may have implications for the airlines' reporting requirements as well as the allocation issue. For example, CAEP is currently discussing the possibility of negotiating with the airline industry on options to set up a voluntary scheme for improving the fuel efficiency of airlines. Such a scheme may involve the need for airlines to engage in a reporting scheme for fuel consumption and emissions. CAEP is furthermore discussing the possibility of setting up an emissions trading scheme based on a system where airlines are allowed to buy emission quotas in other sectors included under the Kyoto Protocol. Such a framework may involve the setting of a cap for aviation emissions and allocation of emission permits to airlines and probably also the allocation of the emissions of CO2 from international aviation to Parties as well as the need for airlines to engage in a reporting scheme for fuel consumption and emissions. Therefore, the discussion on data availability and requirements seems to be closely connected to the issues of options for allocation and control. This explains why this report focuses broadly on all these issues. (au)

  2. Temporal and spatial variability in the aviation NOx-related O3 impact

    International Nuclear Information System (INIS)

    Aviation NOx emissions promote tropospheric ozone formation, which is linked to climate warming and adverse health effects. Modeling studies have quantified the relative impact of aviation NOx on O3 in large geographic regions. As these studies have applied forward modeling techniques, it has not been possible to attribute O3 formation to individual flights. Here we apply the adjoint of the global chemistry–transport model GEOS-Chem to assess the temporal and spatial variability in O3 production due to aviation NOx emissions, which is the first application of an adjoint to this problem. We find that total aviation NOx emitted in October causes 40% more O3 than in April and that Pacific aviation emissions could cause 4–5 times more tropospheric O3 per unit NOx than European or North American emissions. Using this sensitivity approach, the O3 burden attributable to 83 000 unique scheduled civil flights is computed individually. We find that the ten highest total O3-producing flights have origins or destinations in New Zealand or Australia. The top ranked O3-producing flights normalized by fuel burn cause 157 times more normalized O3 formation than the bottom ranked ones. These results show significant spatial and temporal heterogeneity in environmental impacts of aviation NOx emissions. (letter)

  4. Scientific Contributions to Aviation Safety: A User's Perspective

    Science.gov (United States)

    Stills, M.; Guffanti, M.; Salinas, L.

    2009-12-01

    Volcanic ash poses a significant threat to aviation, and steps are taken by commercial operators to avoid encounters in order to protect the safety of passengers and crews. To minimize the risk of damage to aircraft, pilots, dispatchers, and meteorologists plan routes that avoid ash and sometimes execute fuel stops and/or diversions when necessary. Preventing damaging encounters to ensure safety is paramount, but route changes and diversions need to be as efficient as possible in terms of time and fuel expended. Many airlines have experience dealing with possible ash hazards, and dispatchers, pilots, and weather units rely heavily on information from volcano and meteorological scientists. Formal warning messages from civil aviation authorities and aviation weather offices also are an integral part of all operational decisions. Airline operation centers need a range of products and services from scientific groups, including: global synoptic views of activity that may impact flight routes; specific forecasts (predictions) of impending volcanic activity; clear descriptions of ash-dispersion model capabilities and remote-sensing detection techniques. More in-depth issues may also need to be addressed such as dispersion model differences; satellite sensor inadequacy, as it relates to the detection of specific physical phenomena; clarity of labeling of time-series data, such as sequential remote-sensing imagery; and direct access to subject matter experts during events. Information flow needs to be consistent and issued at specific intervals and in specific formats to facilitate procedural development in the aviation community. These issues provide a strong argument in the United States for continued collaboration among air carriers, Volcano Observatories, and Volcanic Ash Advisory Centers.

  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

From a historical point of view, civil society demands not only the absent domination of state but also liberates individuals from the hegemony of state. The article shows that in Indonesia and Malaysian discourse, masyarakat madani is often used to represent the term of civil society. Using this conception, major values of civil society also share with basic ideas within the Medina Treaty in the history of Islam. These ideas include egalitarianism, human rights protection, participation, law and justice enforcement and pluralism. In this frame, the question on whether or not Islam is compatible with the concept of civil society is clearly answered. Muslims could benefit such a concept to build their awareness of being progressive and adaptive to social changes.

    2011-01-01

    This article re-conceptualizes the notion of civil regulation, through an analysis of 775 projects by firms located in 21 Asian countries, wherein we map the state of civil regulation initiatives in the region. We challenge two established assumptions in the Corporate Social Responsibility...... literature. First, contrary to what is commonly argued, we claim that strong states in Asia promote civil regulation in what we call the “paradox of the weak state”. Second, we not only argue that civil regulation is mainly enforced by multinational enterprises willing to promote international social and...... environmental standards; but also that local, small and medium companies play a key role in the development of Asian civil regulation. We call this second finding the “CSR importation trap”. Our findings are supported by evidence on the limitations in the interchangeable properties of business and governments...

    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

    Hoogenstrijd, G.J.

    1993-10-01

    The objective of the title study is to determine whether limits will arise to the predicted growth of commercial aviation because of its associated environmental impact. First, a general description of aviation is given, followed by an outline of the current world aviation fuel consumption, which mainly consists of kerosene consumption in the Northern hemisphere. Also the nature and scale of emissions, caused by aviation, are reviewed. Next, attention is paid to the chemical and physical processes in the atmosphere, related to the aircraft emissions, as well as the environmental effects of the different gases. Model studies show that the impact of emissions can be substantial. Subsequently, the developments of aviation of the last decade and the expected potential developments are considered. During the last decade the emission indices of CO, VOC and soot decreased, whereas the index of NO[sub x] increased. Most of the forecasts assume a doubling of the volume of world civil aviation in the period 1988-2000. No saturation of growth is expected after the year 2000. An average annual fuel growth rate of 2.5% in the period 1990-2010 is forecasted by the International Civil Aviation Organization (ICAO). Finally, the energy consumption and emissions of different modes of transportation are compared with data for aviation. The comparisons show that there is a strong difference in emissions. Per passenger kilometer NO[sub x] emissions by aircraft are in between the emissions of cars and trains and the CO[sub 2] emissions are in the same order of magnitude as those caused by road transport. From the results of the title study it appears that data on emissions and environmental impact of aviation are unreliable. It is concluded that the (current potential) environmental impact of aviation may be significant and that an increase is likely to occur. 30 figs., 25 tabs., 1 appendix, 80 refs.

  18. Nuclear energy and civilization

    International Nuclear Information System (INIS)

    The role of energy is indeed very important since without it there will be no living-things in this world. A country's ability to cultivate energy determines the levels of her civilization and wealth. Sufficient energy supply is needed for economic growth, industrialization, and modernization. In a modern civilization, the prosperity and security of a country depends more on the capability of her people rather than the wealth of her natural resources. Energy supplies the wealth, prosperity and security, and sufficient reliable continuous supply of energy secures the sustainable development. The energy supply to sustain the development has to improve the quality of life covering also the quality of environment to support the ever increasing demand of human race civilization. Energy has a closer relationship with civilization in a modern society and will have to become even closer in the future more civilized and more modern society. The utilization of nuclear energy has, however, some problems and challenges, e.g. misleading information and understanding which need serious efforts for public information, public relation, and public acceptance, and possible deviation of nuclear materials for non-peaceful uses which needs serious efforts for technological and administrative barriers, precaution, prevention, safety, physical protection, safeguard, and transparency. These require cooperation among nuclear community. The cooperation should be more pronounced by heterogeneous growing Asian countries to reach harmony for mutual benefits toward better civilization.

  1. Searching for extraterrestrial civilizations.

    Kuiper, T B; Morris, M

    1977-05-01

    We have argued that planning for a search for extraterrestrial intelligence should involve a minimum number of assumptions. In view of the feasibility (at our present level of understanding) of using nuclear fusion to effect interstellar travel at a speed of 0.1c, it appears unwarranted (at this time) to assume that it would not occur for at least some technologically advanced civilizations. One cannot even conclude that humans would not attempt this within the next few centuries. On the contrary, the most likely future situation, given the maintenance of technological growth and the absence of extraterrestrial interference, is that our civilization will explore and colonize our galactic neighborhood. A comparison of the time scales of galactic evolution and interstellar travel leads to the conclusion that the galaxy is either essentially empty with respect to technological civilizations or extensively colonized. In the former instance, a SETI would be unproductive. In the latter, a SETI could be fruitful if a signal has been deliberately directed at the earth or at an alien outpost, probe, or communication relay station in our solar system. In the former case, an existing antenna would probably be sufficient to detect the signal. In the latter case, success would depend on the way in which the communications were coded. Failure to detect a signal could permit any of the following conclusions: (i) the galaxy is devoid of technological civilizations, advanced beyond our own, (ii) such civilizations exist, but cannot (for some reason which is presently beyond our ken) engage in interstellar colonization, or (iii) such civilizations are not attempting overt contact with terrestrial civilizations and their intercommunications, if present, are not coded in a simple way. To plan at this time for a high-cost, large-array SETI based on the last two possibilities appears to be rather premature. PMID:17760037

    2016-01-01

    The simulation and analysis of global air traffic is limited due to a lack of simulation tools and the difficulty in accessing data sources. This paper provides a global simulation of aviation operations combining flight plans and real air traffic data with historical commercial city-pair aircraft type and schedule data and global atmospheric data. The resulting capability extends the simulation and optimization functions of NASA's Future Air Traffic Management Concept Evaluation Tool (FACET) to global scale. This new capability is used to present results on the evolution of global air traffic patterns from a concentration of traffic inside US, Europe and across the Atlantic Ocean to a more diverse traffic pattern across the globe with accelerated growth in Asia, Australia, Africa and South America. The simulation analyzes seasonal variation in the long-haul wind-optimal traffic patterns in six major regions of the world and provides potential time-savings of wind-optimal routes compared with either great circle routes or current flight-plans if available.

    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

  12. ASEAN SINGLE AVIATION MARKET AND INDONESIA - WILL IT SURVIVE AGAINST THE GIANTS?

    Directory of Open Access Journals (Sweden)

    Ruwantissa Indranath Abeyratne

    2014-11-01

    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.

    1996-12-31

    In the last 15 years, the technical and the economic feasibility of biomass based fuels for general aviation piston engines has been proven. Exhaustive ground and flight tests performed at the Renewable Aviation Fuels Development Center (RAFDC) using ethanol, ethanol/methanol blends, and ETBE have proven these fuels to be superior to aviation gasoline (avgas) in all aspects of performance except range. Two series of Lycoming engines have been certified. Record flights, including a transatlantic flight on pure ethanol, were made to demonstrate the reliability of the fuel. Aerobatic demonstrations with aircraft powered by ethanol, ethanol/methanol, and ETBE were flown at major airshows around the world. the use of bio-based fuels for aviation will benefit energy security, improve the balance of trade, domestic economy, and environmental quality. The United States has the resources to supply the aviation community`s needs with a domestically produced fuel using current available technology. The adoption of a renewable fuel in place of conventional petroleum-based fuels for aviation piston and turbine engines is long overdue.

    2008-12-01

    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.

    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

    We present an overview of research conducted by NASA Aeronautics Research Mission Directorate to evaluate the performance and emissions of "drop-in" alternative jet fuels, highlighting experiment design and results from the Alternative Aviation Fuel Experiments (AAFEX-I & -II) and Alternative Fuel-Effects on Contrails and Cruise Emissions flight series (ACCESS-I & II). These projects included almost 100 hours of sampling exhaust emissions from the NASA DC-8 aircraft in both ground and airborne operation and at idle to takeoff thrust settings. Tested fuels included Fischer-Tropsch (FT) synthetic kerosenes manufactured from coal and natural-gas feedstocks; Hydro-treated Esters and Fatty-Acids (HEFA) fuels made from beef-tallow and camelina-plant oil; and 50:50 blends of these alternative fuels with Jet A. Experiments were also conducted with FT and Jet A fuels doped with tetrahydrothiophene to examine the effects of fuel sulfur on volatile aerosol and contrail formation and microphysical properties. Results indicate that although the absence of aromatic compounds in the alternative fuels caused DC-8 fuel-system leaks, the fuels did not compromise engine performance or combustion efficiency. And whereas the alternative fuels produced only slightly different gas-phase emissions, dramatic reductions in non-volatile particulate matter (nvPM) emissions were observed when burning the pure alternative fuels, particularly at low thrust settings where particle number and mass emissions were an order of magnitude lower than measured from standard jet fuel combustion; 50:50 blends of Jet A and alternative fuels typically reduced nvPM emissions by ~50% across all thrust settings. Alternative fuels with the highest hydrogen content produced the greatest nvPM reductions. For Jet A and fuel blends, nvPM emissions were positively correlated with fuel aromatic and naphthalene content. Fuel sulfur content regulated nucleation mode aerosol number and mass concentrations within aging

    1977-01-01

    Three interrelated assumptions are critically examined in an attempt to outline a productive strategy for a search for extraterrestrial intelligence. Questions concerning the feasibility of interstellar travel are investigated. It is concluded that the probability of interstellar travel is high enough that, given a modest number of advanced civilizations, at least one of them will engage in interstellar voyages and colonize the galaxy. Assuming, however, that technological civilizations are rare the galaxy would be essentially unpopulated. Attention is given to the present lack of contact with extraterrestrial beings and frequencies for interstellar beacons.

  2. Economic conditions of technical changes in world civil air transport

    2008-01-01

    Full Text Available The world economic environment of the turn of the century produced many new challenges to civil aviation in expectation of a continued growth in the transportation of passengers and cargo. To meet this growing demand, it will be necessary to increase the fleet and to modernise infrastructure – a process hampered by finances and capacity constraints.Such constraints are especially pressing with regard to the acquisition of new types of large aircraft such as the Airbus A380 and the Boeing 787 and 747-8. Future dominance of the market is, however, difficult to predict, as this will be the outcome of a combination of uncertain parameters.

  3. Emerging trends in alternative aviation fuels

    Science.gov (United States)

    Corbett, Cody

    The days of petroleum-based aviation fuels are numbered. New regulations to be set in place in the coming years will force current fuels to be phased out in favor of cleaner fuels with less toxic emissions. The alternative fuel industry has already taken its foothold in other modes of transportation, and aviation will soon follow suit. Many companies have cropped up over the last decade, and a few have been around longer, that work hard to develop the alternative aviation fuels of the future. It is important, however, for the aviation community to know what to expect and when to expect it concerning alternative fuels. This study investigates where various companies in the alternative aviation fuel industry currently stand in their development and production processes, and how their products will affect aircraft owners and operators. By interviewing representatives from these companies and analyzing their responses to identify trends, an educated prediction can be made about where the industry is headed and when the aviation community can expect these fuel to be available. The findings of this study indicate that many companies are still in their developmental stages, with a few notable outliers, and that most of these companies expect to see production of their product by 2017. Also, the fuel manufacturers are dealing with all the legal hurdles regarding alternative fuels, so little to no effort will be required on the part of the consumer. These findings, along with their analysis, will enable the aviation community to make educated decisions concerning fuel and their aircraft, as well and do their part to help these beneficial fuels get to market.

    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.

    Aviation alters the composition of the atmosphere globally and can thus drive climate change and ozone depletion. The last major international assessment of these impacts was made by the Intergovernmental Panel on Climate Change (IPCC) in 1999. Here, a comprehensive updated assessment of aviation is provided. Scientific advances since the 1999 assessment have reduced key uncertainties, sharpening the quantitative evaluation, yet the basic conclusions remain the same. The climate impact of aviation is driven by long-term impacts from CO 2 emissions and shorter-term impacts from non-CO 2 emissions and effects, which include the emissions of water vapour, particles and nitrogen oxides (NO x). The present-day radiative forcing from aviation (2005) is estimated to be 55 mW m -2 (excluding cirrus cloud enhancement), which represents some 3.5% (range 1.3-10%, 90% likelihood range) of current anthropogenic forcing, or 78 mW m -2 including cirrus cloud enhancement, representing 4.9% of current forcing (range 2-14%, 90% likelihood range). According to two SRES-compatible scenarios, future forcings may increase by factors of 3-4 over 2000 levels, in 2050. The effects of aviation emissions of CO 2 on global mean surface temperature last for many hundreds of years (in common with other sources), whilst its non-CO 2 effects on temperature last for decades. Much progress has been made in the last ten years on characterizing emissions, although major uncertainties remain over the nature of particles. Emissions of NO x result in production of ozone, a climate warming gas, and the reduction of ambient methane (a cooling effect) although the overall balance is warming, based upon current understanding. These NO x emissions from current subsonic aviation do not appear to deplete stratospheric ozone. Despite the progress made on modelling aviation's impacts on tropospheric chemistry, there remains a significant spread in model results. The knowledge of aviation's impacts on cloudiness

    Science.gov (United States)

    Connell, Linda J.

    1997-01-01

    The Aviation Safety Reporting System (ASRS) was established in 1976 under an agreement between the Federal Aviation Administration (FAA) and the National Aeronautics and Space Administration (NASA). This cooperative safety program invites pilots, air traffic controllers, flight attendants, maintenance personnel, and others to voluntarily report to NASA any aviation incident or safety hazard. The FAA provides most of the program funding. NASA administers the program, sets its policies in consultation with the FAA and aviation community, and receives the reports submitted to the program. The FAA offers those who use the ASRS program two important reporting guarantees: confidentiality and limited immunity. Reports sent to ASRS are held in strict confidence. More than 350,000 reports have been submitted since the program's beginning without a single reporter's identity being revealed. ASRS removes all personal names and other potentially identifying information before entering reports into its database. This system is a very successful, proof-of-concept for gathering safety data in order to provide timely information about safety issues. The ASRS information is crucial to aviation safety efforts both nationally and internationally. It can be utilized as the first step in safety by providing the direction and content to informed policies, procedures, and research, especially human factors. The ASRS process and procedures will be presented as one model of safety reporting feedback systems.

    Full Text Available Resumen: La crisis económica de Argentina en años recientes derivó en la pérdida de legitimidad de las instituciones políticas del país. La medida de suspensión de las libertades y garantías de derechos individuales provocó una desobediencia civil generalizada que llevó a miles de personas a manifestar pacíficamente su repudio al gobierno de Fernando de la Rúa. Este gesto ciudadano espontáneo, desorganizado y voluntario sirvió, entre otras cosas, para formar una autodeterminación primaria directa de la voluntad popular y una autocomprensión del carácter democrático de la sociedad civil. La justificación de la desobediencia se basaba en una cuestión de derechos. Todos los manifestantes afirmaban que tenían derecho a desobedecer porque la desobediencia, en ciertas circunstancias, era un derecho humano. ¿Pero puede ser la desobediencia civil, en un Estado de derecho, un auténtico derecho? ¿En qué circunstancias, en el contexto legal y fuera de los derechos habituales de resistencia como huelga, manifestación, etcétera, se puede desobedecer una norma legal? Abstract: The recent economic crisis in Argentina led to the loss of identity of the country’s political institutions. The measure of the suspension of freedom and of the guarantee of individual rights provoked a generalized civil disobedience which led thousands of people to peacefully demonstrate their repudiation of Fernando de la Rúa’s government. This spontaneous, unorganized and voluntary action by the citizens served, among other things, to form a direct primary self-determination of the will of the people and a self-understanding of the democratic character of civil society. The justification of the disobedience was based on a question of rights. All the demonstrators asserted that they had the right to disobey because disobedience, in certain circumstances, was a human right. However, can civil disobedience, in a constitutional state, be an authentic right

  18. A volcanic activity alert-level system for aviation: review of its development and application in Alaska

    Science.gov (United States)

    2013-01-01

    An alert-level system for communicating volcano hazard information to the aviation industry was devised by the Alaska Volcano Observatory (AVO) during the 1989–1990 eruption of Redoubt Volcano. The system uses a simple, color-coded ranking that focuses on volcanic ash emissions: Green—normal background; Yellow—signs of unrest; Orange—precursory unrest or minor ash eruption; Red—major ash eruption imminent or underway. The color code has been successfully applied on a regional scale in Alaska for a sustained period. During 2002–2011, elevated color codes were assigned by AVO to 13 volcanoes, eight of which erupted; for that decade, one or more Alaskan volcanoes were at Yellow on 67 % of days and at Orange or Red on 12 % of days. As evidence of its utility, the color code system is integrated into procedures of agencies responsible for air-traffic management and aviation meteorology in Alaska. Furthermore, it is endorsed as a key part of globally coordinated protocols established by the International Civil Aviation Organization to provide warnings of ash hazards to aviation worldwide. The color code and accompanying structured message (called a Volcano Observatory Notice for Aviation) comprise an effective early-warning message system according to the United Nations International Strategy for Disaster Reduction. The aviation color code system currently is used in the United States, Russia, New Zealand, Iceland, and partially in the Philippines, Papua New Guinea, and Indonesia. Although there are some barriers to implementation, with continued education and outreach to Volcano Observatories worldwide, greater use of the aviation color code system is achievable.

    Evolutionary arguments are presented in favor of the existence of civilization on a galactic scale. Patterns of physical, chemical, biological, social and cultural evolution leading to increasing levels of complexity are pointed out and explained thermodynamically in terms of the maximization of free energy dissipation in the environment of the organized system. The possibility of the evolution of a global and then a galactic human civilization is considered, and probabilities that the galaxy is presently in its colonization state and that life could have evolved to its present state on earth are discussed. Fermi's paradox of the absence of extraterrestrials in light of the probability of their existence is noted, and a variety of possible explanations is indicated. Finally, it is argued that although mankind may be the first occurrence of intelligence in the galaxy, it is unjustified to presume that this is so.

    Jakub Kociubiński

    2011-06-01

    Full Text Available The purpose of this paper is to provide a brief overview of the issue of definition of relevant market in civil aviation within the European Union. The liberalization of the market since the early 1990s has led to a rapid increase in the number of airlines operating in the EU. The increase in the competitiveness of the market has brought many positive changes for passengers, such as lower fares and a better network of connections. At the same time it has created a risk that the airlines, in order to gain a competitive edge, would infringe the rules of competition. This is especially important in the context of the phenomenon that is the development of the airline alliances, which could lead to an abuse of a dominant position. A clear definition of the relevant market is a first step in an assessment of whether such an abuse occurred. This paper focus on the elements that Internal Market regulator, the European Commission, takes into consideration when defining relevant market in the airline industry.

    Carpentier, J. [Comite Avion-Ozone, 75 - Paris (France)

    1997-12-31

    The commercial air traffic, either for business or for tourism will induce a special increase of long haul flights, with cruising altitudes of about 10 to 12 km. These altitudes correspond to the upper troposphere for the low latitudes (tropical zones) and to the lower stratosphere for middle and high latitudes. The prospect of a world air traffic multiplied by a factor 2 within the next fifteen years, with an increasing part of the long-haul flights, raises the problem of the impact of aircraft emissions on the upper troposphere and on the lower stratosphere. The air traffic growth which is forecast for the next two decades as well as for long term will be larger than the GDP growth. But technical progress concerning airframes, engines, navigation systems and improvements of air traffic control and airports will keep the aircraft emissions growth at a rate which will not exceed the GDP growth rate. The aviation`s share of global anthropogenic emissions will remain lower than 3 percent. The regulations related to NO{sub x} emissions from aircraft will reduce the aviation`s share of nitrogen oxides from human sources at a level of 1 percent. (R.P.)

Countries around the world, but mainly the Brazil, Russia, India, China and South Africa group (BRICS and the US, denounced the EU's initiate as illegal and unilateral. Following a decade of frustrated negotiations at the International Civil Aviation Organization (ICAO, this paper interrogates why such measure, in principle climate-friendly, inspired so much global resentment. I argue that concerns with competitiveness and risks of legal inconsistency are important, but insufficient elements to explain the core of the conflict. The paper suggests that the EU was strongly criticized because third countries perceived this action as an imposed solution, which fostered an environment of distrust. Therefore, I claim that the problem has more to do with a normative divide than with a substantive divergence on what should be done regarding aviation emissions. My analysis is informed by the present literature on the links between trade and climate change, but gives particular weight to first-hand information through interviews with key stakeholders. The paper is divided in three parts. First, it presents the scope of the EU directive in historical perspective. Second, it explores the EU's measure through three different angles: legal, economical and political. The final part explores some possible solutions to overcome these divergences.

  3. Review of aviation safety measures which have application to aviation accident prevention.

    Science.gov (United States)

    Doughtery, J D

    1975-01-01

    Introduction of certain human-factors techniques has been followed by market reduction in military and airline accident rates. In this study, these safety measures are analyzed to determine the value of their application to general aviation activity. Some techniques are already in use. They are: 1. medical evaluation of iarcrews; 2. aeronautical innovations which tailor the machine to the man; 3. imporvement of precision navigational air traffic control and flight procedures; 4. standardization of flight training and flight procedures. A remaining field of interest, and one which appears to be underused, is that of supervision. After ending his association with the flight instructor, the general aviation pilot is essentially unsupervised. Accident data gathered over several years show that with increases in the proportion of pilots who have not maintained an association with a flight instructor, the general aviation fatal accident rate is increased. Current regulations, which require revalidation of airman's certificates, provide a method by which this association can be maintained. The flight instructor, or some similar aviation professional, can maintain an element of supervision with otherwise independent general aviation pilots. Data from previous years supports the hypothesis that such a program would make a substantial improvement in general aviation safety. PMID:1115703

  5. General Aviation Pilots' Perceived Usage and Valuation of Aviation Weather Information Sources

    Science.gov (United States)

    Latorella, Kara; Lane, Suzanne; Garland, Daniel

    2002-01-01

    Aviation suffers many accidents due to the lack of good weather information in flight. Existing aviation weather information is difficult to obtain when it is most needed and is not well formatted for in-flight use. Because it is generally presented aurally, aviation weather information is difficult to integrate with spatial flight information and retain for reference. Efforts, by NASA's Aviation Weather Information (AWIN) team and others, to improve weather information accessibility, usability and decision aiding will enhance General Aviation (GA) pilots' weather situation awareness and decision-making and therefore should improve the safety of GA flight. Consideration of pilots' economic concerns will ensure that in-flight weather information systems are financially accessible to GA pilots as well. The purpose of this survey was to describe how aviation operator communities gather and use weather information as well as how weather related decisions are made between flight crews and supporting personnel. Pilots of small GA aircraft experience the most weather-related accidents as well as the most fatal weather related accident. For this reason, the survey design and advertisement focused on encouraging participation from GA pilots. Perhaps as a result of this emphasis, most responses, 97 responses or 85% of the entire response set, were from GA pilots, This paper presents only analysis of these GA pilots' responses. The insights provided by this survey regarding GA pilots' perceived value and usage of current aviation weather information. services, and products provide a basis for technological approaches to improve GA safety. Results of this survey are discussed in the context of survey limitations and prior work, and serve as the foundation for a model of weather information value, guidance for the design of in-flight weather information systems, and definition of further research toward their development.

  6. Which future for aviation bio-fuels?

    International Nuclear Information System (INIS)

    This collective report proposes a detailed overview of the evolution of aviation fuels and bio-fuels from technological, regulatory and economic points of view. It also proposes a road-map for possible future evolutions, and outlines the different assessments between American and European countries regarding the predictions for the beginning of industrial production and use of bio-jet-fuel. After having recalled international objectives, an overview of European and French commitments for technological and operational advances, and a discussion of the role of bio-fuels in the carbon cycle, the report presents various technical constraints met in aircraft industry and describes the role bio-fuels may have. The next part proposes an overview of bio-fuels which are industrially produced in the world in 2013. The authors then focus on aviation bio-fuels (main production processes, thermo-chemical processes), discuss the political context, and examine obstacles, partnerships and the role of public authorities

  7. Cosmic rays and dosimetry at aviation altitudes

    International Nuclear Information System (INIS)

    Recent concerns regarding the effects of the cosmic radiation field at aircraft altitudes on aircrew have resulted in a renewed interest in detailed measurements of the neutral and charged particle components in the atmosphere. CR-39 nuclear track detectors have been employed on a number of subsonic and supersonic aircraft to measure charge spectra and LET spectra at aircraft altitudes. These detectors are ideal for long term exposures required for these studies and their passive nature makes them suitable for an environment where interference with flight instrumentation could be a problem. We report here on measurements and analysis of short range tracks which were produced by high LET particles generated mainly by neutron interactions at aviation altitudes. In order to test the overall validity of the technique measurements were also carried out at the CERN-CEC field which simulates the radiation field at aviation altitudes and good agreement was found with dose values obtained using mainly heavy ion calibration

  1. The rivers of civilization

    Science.gov (United States)

    Macklin, Mark G.; Lewin, John

    2015-04-01

    The hydromorphic regimes that underpinned Old World river-based civilizations are reviewed in light of recent research. Notable Holocene climatic changes varied from region to region, whilst the dynamics of floodplain environments were equally diverse, with river channel changes significantly affecting human settlement. There were longer-term trends in Holocene hydroclimate and multi-centennial length 'flood-rich' and 'flood-poor' episodes. These impacted on five identified flooding and settlement scenarios: (i) alluvial fans and aprons; (ii) laterally mobile rivers; (iii) rivers with well-developed levees and flood basins; (iv) river systems characterised by avulsions and floodouts; and (v) large river-fed wetlands. This gave a range of changes that were either more or less regular or incremental from year-to-year (and thus potentially manageable) or catastrophic. The latter might be sudden during a flood event or a few seasons (acute), or over longer periods extending over many decades or even centuries (chronic). The geomorphic and environmental impacts of these events on riparian societies were very often irreversible. Contrasts are made between allogenic and autogenic mechanism for imposing environmental stress on riverine communities and a distinction is made between channel avulsion and contraction responses. Floods, droughts and river channel changes can precondition as well as trigger environmental crises and societal collapse. The Nile system currently offers the best set of independently dated Holocene fluvial and archaeological records, and the contrasted effects of changing hydromorphological regimes on floodwater farming are examined. The persistence of civilizations depended essentially on the societies that maintained them, but they were also understandably resilient in some environments (Pharaonic Egypt in the Egyptian Nile), appear to have had more limited windows of opportunity in others (the Kerma Kingdom in the Nubian Nile), or required

    During the development of their work, the aviator pilots are exposed at high levels of natural radiation of bottom caused mainly by the cosmic radiation of galactic origin and lot. For such reason, the Metropolitan Autonomous University (UAM) and the Union Association of Aviator Pilots (ASPA), subscribed an agreement with the purpose of to measure the doses of ionizing radiation received by the aviator pilots of diverse air companies that man different types of airships and to determine if these doses surpass the one limit of 0.11 mSv/h settled down by the IAEA for the public in general; and if therefore, these workers should be considered as personnel occupationally exposed. In this work the obtained results when measuring the absorbed dose received by Mexican civil aviator pilots during the development of their work, using thermoluminescent dosemeters of LiF:Mg,Cu,P + Ptfe of national production are presented. The obtained results during the years of 2001 and 2002 show that the monthly doses received by the pilots surpass the one it limits established for the public in general, for what they should be considered as personnel occupationally exposed.

    The Aviation Data Integration System (ADIS) of Ames Research Center has been established to promote analysis of aviation data by airlines and other interested users for purposes of enhancing the quality (especially safety) of flight operations. The ADIS is a system of computer hardware and software for collecting, integrating, and disseminating aviation data pertaining to flights and specified flight events that involve one or more airline(s). The ADIS is secure in the sense that care is taken to ensure the integrity of sources of collected data and to verify the authorizations of requesters to receive data. Most importantly, the ADIS removes a disincentive to collection and exchange of useful data by providing for automatic removal of information that could be used to identify specific flights and crewmembers. Such information, denoted sensitive information, includes flight data (here signifying data collected by sensors aboard an aircraft during flight), weather data for a specified route on a specified date, date and time, and any other information traceable to a specific flight. The removal of information that could be used to perform such tracing is called "deidentification." Airlines are often reluctant to keep flight data in identifiable form because of concerns about loss of anonymity. Hence, one of the things needed to promote retention and analysis of aviation data is an automated means of de-identification of archived flight data to enable integration of flight data with non-flight aviation data while preserving anonymity. Preferably, such an automated means would enable end users of the data to continue to use pre-existing data-analysis software to identify anomalies in flight data without identifying a specific anomalous flight. It would then also be possible to perform statistical analyses of integrated data. These needs are satisfied by the ADIS, which enables an end user to request aviation data associated with de-identified flight data. The ADIS

  13. Software in military aviation and drone mishaps: Analysis and recommendations for the investigation process

    International Nuclear Information System (INIS)

    Software plays a central role in military systems. It is also an important factor in many recent incidents and accidents. A safety gap is growing between our software-intensive technological capabilities and our understanding of the ways they can fail or lead to accidents. Traditional forms of accident investigation are poorly equipped to trace the sources of software failure, for instance software does not age in the same way that hardware components fail over time. As such, it can be hard to trace the causes of software failure or mechanisms by which it contributed to accidents back into the development and procurement chain to address the deeper, systemic causes of potential accidents. To identify some of these failure mechanisms, we examined the database of the Air Force Accident Investigation Board (AIB) and analyzed mishaps in which software was involved. Although we have chosen to focus on military aviation, many of the insights also apply to civil aviation. Our analysis led to several results and recommendations. Some were specific and related for example to specific shortcomings in the testing and validation of particular avionic subsystems. Others were broader in scope: for instance, we challenged both the investigation process (aspects of) and the findings in several cases, and we provided recommendations, technical and organizational, for improvements. We also identified important safety blind spots in the investigations with respect to software, whose contribution to the escalation of the adverse events was often neglected in the accident reports. These blind spots, we argued, constitute an important missed learning opportunity for improving accident prevention, and it is especially unfortunate at a time when Remotely Piloted Air Systems (RPAS) are being integrated into the National Airspace. Our findings support the growing recognition that the traditional notion of software failure as non-compliance with requirements is too limited to capture the

  14. Civil liberties and nuclear terrorism

    International Nuclear Information System (INIS)

    The importance of preventing nuclear terrorism is so great that it is easy to believe that the usual concern with civil liberties must take a back seat. But it is precisely when emergencies are invoked that the authors must not forget the importance of freedoms. Emergency powers are easily abused, and, even in the absence of abuse, mistakes can be made. It is hard to understand why they care about civil liberties if every suspect is guilty, every wiretap is necessary, and every search is justified. But sometimes suspects are innocent, wiretaps are used for political ends, and searches disrupt lives to no end. Civil liberties do not exist in a vacuum. If society is destroyed, civil liberties are likely to be destroyed as well. Virtually every legal doctrine this study addresses involves a recognition that individual rights must be balanced against valid social needs. The civil liberties focus on here fall under the general headings of freedom of speech and association, privacy, due process rights for suspects, and freedom from unreasonable searches and seizures. One essential point applied to all these areas: although a counterterrorist activity is legal, that does not mean the activity has no impact on civil liberties. It may be legal, for example, to have a massive federal police force that provides hundreds of guards for every shipment of plutonium. Even so, that procedure still raises civil liberties concerns, since many Americans would feel less free in a society of that type

  15. Technical Civilizations in the Galaxy

    Science.gov (United States)

    Jones, Harry

    2005-01-01

    Are there other technical civilizations in the galaxy? Past analyses come to different conclusions. Cocconi and Morrison demonstrated in 1959 that interstellar radio communication was possible and Drake conducted the first search for beacons in 1960. The Drake equation estimates the number of galactic civilizations that are transmitting beacons as the product of the rate of star formation in the galaxy, the fraction of stars with planets, their average number of earthlike planets, the fraction with intelligent life and interstellar communication, and the average lifetime of a technical civilization. The Drake model of the galaxy contains many technical civilizations with communication but no interstellar travel. Michael Hart in 1975 strongly challenged this model. Starting with the fact that no extraterrestrials have been observed on Earth, and assuming that interstellar colonization is possible, he concluded that it was very likely that we are the first civilization in our galaxy and that searching or beacons is probably a waste of time and money. The Fermi paradox similarly reasons that if extraterrestrials exist: they should be here, and asks, Where are they? The Hart/Fermi model of the galaxy contains only our civilization and suggests we may colonize the galaxy. A third galactic model is that we are alone but will never develop interstellar travel. The fourth alternate model has many technical civilizations, with interstellar travel and colonization. The possibilities are clear and momentous. Either we are the only technical civilization in the galaxy or there are others. Technical civilizations will colonize the galaxy or not. We have four cosmic conjectures - one or many, colonization or not - but however unlikely they seem based on our limited evidence, one of these four models must be collect.

  16. Aviation graduates' competencies, 2000--2007: Perceptions of aviation educators and industry representatives in the United States

    Science.gov (United States)

    Bridewell, John B.

    This study surveyed the perceptions of collegiate aviation educators, collegiate aviation institution representatives, and aviation industry stakeholders who were members of the University Aviation Association as of February 5, 2007. Survey forms were sent to 353 prospective participants and there was an overall response rate of 47.6%. The survey consisted of a list of 16 knowledge and skill competencies with Likert-type responses for each participant to indicate the level of importance each placed upon those competencies for collegiate aviation graduates and of the level of satisfaction each had that collegiate aviation graduates actually possessed those competencies upon graduation. Two open-ended questions pertained to the strengths and weaknesses of collegiate aviation programs or their graduates. Another allowed for general comments. The statistical analyses indicated that all three groups were most satisfied with graduates' technical skills and least satisfied with communications skills. Analyses indicated that a balance of technical skills and a liberal education was essential for program success. All knowledge and skill competencies were shown to have high to very high importance levels, but only medium to high satisfaction levels. Results indicated that graduates were perceived to possess all stated competencies, but to a lesser degree than desired. Successful collegiate aviation programs existed, but there was room for improvement. Success was program or graduate speck, with no ubiquitous definition of what constituted a successful collegiate aviation program. Aviation industry needs must be addressed by academia for any collegiate aviation program to be successful, but results indicated that the aviation industry needs to take a larger role in the development and refinement of collegiate aviation programs. Finances for institutions, programs, and students were a major concern for the foreseeable future. Administrators should consider how their actions

    2016-05-01

    In this paper, a review of the background and some drivers are provided for X-ray screening for aviation security. Some of the key considerations are highlighted along with impacts of the image-based approaches and signature approaches. The role of information theory is discussed along with some recent work that may influence the technical direction by posing the question: "what measurements, parameters and metrics should be considered in future system design?" A path forward should be based on information theory, however electronic machines will likely interface with humans and be dollar-cost driven, so ultimately solutions must consider additional parameters other than only technical performance factors.

    Plots and tables, compiled from Department of Energy (and predecessor agency) inspection reports from 1969 to 1980, present ranges, averages, extremes, and trends for most of the 22 properties of Jet A aviation turbine fuel. In recent years, average values of aromatics content, mercaptan sulfur content, distillation temperature of 10 percent recovered, smoke point, and freezing point show small but recognizable trends toward their specification limits. About 80 percent of the fuel samples had at least one property near specification, defined as within a standard band about the specification limit. By far the most common near-specification properties were aromatics content, smoke point, and freezing point.

    Our focus is the evolution of business strategies and network structure decisions in the commercial passenger aviation industry. The paper reviews the growth of hub-and-spoke networks as the dominant business model following deregulation in the latter part of the 20 century, followed by the emergence of value-based airlines as a global phenomenon at the end of the century. The paper highlights the link between airline business strategies and network structures, and examines the resulting competition between divergent network structure business models. In this context we discuss issues of market structure stability and the role played by competition policy.

  2. A psychologist's view of validating aviation systems

    Science.gov (United States)

    Stein, Earl S.; Wagner, Dan

    1994-01-01

    All systems, no matter what they are designed to do, have shortcomings that may make them less productive than was hoped during the initial development. Such shortcomings can arise at any stage of development: from conception to the end of the implementation life cycle. While systems failure and errors of a lesser magnitude can occur as a function of mechanical or software breakdown, the majority of such problems, in aviation are usually laid on the shoulders of the human operator and, to a lesser extent, on human factors. The operator bears the responsibility and blame even though, from a human factors perspective, error may have been designed into the system. Human factors is not a new concept in aviation. The name may be new, but the issues related to operators in the loop date back to the industrial revolution of the nineteenth century and certainly to the aviation build-up for World War I. During this first global confrontation, military services from all sides discovered rather quickly that poor selection and training led to drastically increased personnel losses. While hardware design became an issue later, the early efforts were primarily focused on increased care in pilot selection and on their training. This actually involved early labor-intensive simulation, using such devices as sticks and chairs mounted on rope networks which could be manually moved in response to control input. The use of selection criteria and improved training led to more viable person-machine systems. More pilots survived training and their first ten missions in the air, a rule of thumb arrived at by experience which predicted ultimate survival better than any other. This rule was to hold through World War II. At that time, personnel selection and training became very sophisticated based on previous standards. Also, many psychologists were drafted into Army Air Corps programs which were geared towards refining the human factor. However, despite the talent involved in these programs

    Hayhurst, Kelly J.; Maddalon, Jeffrey M.; Morris, A. Terry; Neogi, Natasha; Verstynen, Harry A.

    2014-01-01

    While progress is being made on integrating unmanned aircraft systems (UAS) into our national airspace on a broad scale, much work remains to establish appropriate certification standards and operational procedures, particularly with respect to routine commercial operations. This paper summarizes research to examine the extent to which today's civil aircraft taxonomy applies to UAS, and, if needed, how that taxonomy could be amended to better cover different UAS designs and operations. Factors that shape the current taxonomy, as defined in the Federal Aviation Regulations, were assessed for applicability to UAS, potential incompatibilities were identified, and additional factors were proposed that might be useful for an updated aircraft taxonomy intended to cover UAS. The results suggest the possibility of constructing new groups in the taxonomy for UAS under a restricted category that share common airworthiness standards. Establishing distinct groups for UAS and associated standards that enable low risk operations for compensation or hire could be a timely step toward full integration. Such a step would allow the civil aviation industry and regulators to gain valuable experience with UAS while carefully controlling access and potential harm to the aviation system as a whole.

  3. Accident-precipitating factors for crashes in turbine-powered general aviation aircraft.

    Science.gov (United States)

    Boyd, Douglas D; Stolzer, Alan

    2016-01-01

    General aviation (14CFR Part 91) accounts for 83% of civil aviation fatalities. While much research has focused on accident causes/pilot demographics in this aviation sector, studies to identify factors leading up to the crash (accident-precipitating factors) are few. Such information could inform on pre-emptive remedial action. With this in mind and considering the paucity of research on turbine-powered aircraft accidents the study objectives were to identify accident-precipitating factors and determine if the accident rate has changed over time for such aircraft operating under 14CFR Part 91. The NTSB Access database was queried for accidents in airplanes (turbine engines and occurring between 1989 and 2013. We developed and utilized an accident-precipitating factor taxonomy. Statistical analyses employed logistic regression, contingency tables and a generalized linear model with Poisson distribution. The "Checklist/Flight Manual Not Followed" was the most frequent accident-precipitating factor category and carried an excess risk (OR 2.34) for an accident with a fatal and/or serious occupant injury. This elevated risk reflected an over-representation of accidents with fatal and/or serious injury outcomes (pturbine aircraft accident rate over the study period was likely due, in part, to a 6-fold increased representation of single engine airplanes. In conclusion, our study is the first to identify novel precursive factors for accidents involving turbine aircraft operating under 14CFR Part 91. This research highlights areas that should receive further emphasis in training/recurrency in a pre-emptive attempt to nullify candidate accident-precipitating factor(s). PMID:26590507

  4. Incentive-based regulation of CO2 emissions from international aviation

    International Nuclear Information System (INIS)

    We explore the possibilities of using incentive-based environmental regulations of CO2 emissions from international civil aviation. In theory incentive-based instruments such as an emission charge or a tradable emission permit system are better regulations than so-called command-and-control regulations such as emission limits or technology standards. However, the implementation of these instruments is a complex issue. We therefore describe and discuss how an emission charge and a tradable emission permit system for international aviation should be designed in order to improve efficiency. We also compare these two types of regulations. In brief, we find that an emission charge and a tradable emission permit system in which the permits are auctioned have more or less the same characteristics. The main advantage of a tradable emission permit system is that the effect, in terms of emission reductions, is known. On the other hand, we show that under uncertainty an emission charge is preferred. The choice of regulation is a political decision and it does not seem likely that an environmental charge or a tradable emission permit system would be implemented without consideration of the costs of the regulation. Revenue-neutral charges or gratis distribution of permits would, for this reason, be realistic choices of regulations. However, such actions are likely to result in less stringent regulations and other negative welfare effects.(author)

  5. An airfoil for general aviation applications

    Science.gov (United States)

    Selig, Michael S.; Maughmer, Mark D.; Somers, Dan M.

    1990-01-01

    A new airfoil, the NLF(1)-0115, has been recently designed at the NASA Langley Research Center for use in general-aviation applications. During the development of this airfoil, special emphasis was placed on experiences and observations gleaned from other successful general-aviation airfoils. For example, the flight lift-coefficient range is the same as that of the turbulent-flow NACA 23015 airfoil. Also, although beneficial for reducing drag and having large amounts of lift, the NLF(1)-0115 avoids the use of aft loading which can lead to large stick forces if utilized on portions of the wing having ailerons. Furthermore, not using aft loading eliminates the concern that the high pitching-moment coefficient generated by such airfoils can result in large trim drags if cruise flaps are not employed. The NASA NLF(1)-0115 has a thickness of 15 percent. It is designed primarily for general-aviation aircraft with wing loadings of 718 to 958 N/sq m (15 to 20 lb/sq ft). Low profile drag as a result of laminar flow is obtained over the range from c sub l = 0.1 and R = 9x10(exp 6) (the cruise condition) to c sub l = 0.6 and R = 4 x 10(exp 6) (the climb condition). While this airfoil can be used with flaps, it is designed to achieve c(sub l, max) = 1.5 at R = 2.6 x 10(exp 6) without flaps. The zero-lift pitching moment is held at c sub m sub o = 0.055. The hinge moment for a .20c aileron is fixed at a value equal to that of the NACA 63 sub 2-215 airfoil, c sub h = 0.00216. The loss in c (sub l, max) due to leading edge roughness, rain, or insects at R = 2.6 x 10 (exp 6) is 11 percent as compared with 14 percent for the NACA 23015.

    Predictions are made concerning the development of alternative energy sources in the light of the present national energy situation. Particular emphasis is given to the impact of alternative fuels development on aviation fuels. The future outlook for aircraft fuels is that for the near term, there possibly will be no major fuel changes, but minor specification changes may be possible if supplies decrease. In the midterm, a broad cut fuel may be used if current development efforts are successful. As synfuel production levels increase beyond the 1990's there may be some mixtures of petroleum-based and synfuel products with the possibility of some shale distillate and indirect coal liquefaction products near the year 2000.

    Full Text Available The most applicable models in safety management put the human factors, employers’ attitudes and behaviors at the center. This study reports an investigation of job satisfaction among business aviation technicians. A demographic information form and Job Satisfaction Survey (JSS were used to collect data from 44 individuals. Data was analyzed using ANOVA and Student’s t-test. Our results show that there is significant difference in total job satisfaction levels with regard to marital status while other personal factors are not related to the total job satisfaction levels. However several sub dimensions of job satisfaction are affected by the workers’ military or civilian origin, their training background, types of companies they work in or their license category. No difference is found in age and position groups. Secondly, study shows that technicians are the most satisfied from the nature of their work, while they are the least satisfied by operational procedures.

  15. Urgent epidemic control mechanism for aviation networks

    Peng, Chengbin

    2011-01-01

    In the current century, the highly developed transportation system can not only boost the economy, but also greatly accelerate the spreading of epidemics. While some epidemic diseases may infect quite a number of people ahead of our awareness, the health care resources such as vaccines and the medical staff are usually locally or even globally insufficient. In this research, with the network of major aviation routes as an example, we present a method to determine the optimal locations to allocate the medical service in order to minimize the impact of the infectious disease with limited resources. Specifically, we demonstrate that when the medical resources are insufficient, we should concentrate our efforts on the travelers with the objective of effectively controlling the spreading rate of the epidemic diseases. © 2011 Springer-Verlag Berlin Heidelberg.

    2011-01-01

    Full Text Available The aerospace environment is a dynamic interaction between man, machine and the environment. Skin diseases are not particularly significant aeromedically, yet they could permanently affect an aviator′s status for continued flying duty. A number of dermatological conditions lend themselves to flying restrictions for the aviator. Aircrew and ground crew are exposed to a myriad of elements that could also adversely impact their flying status. Inflight stresses during flights as well as space travel could impact certain behaviors from a dermatological standpoint. With the advent of space tourism, dermatological issues would form an integral part of medical clearances. With limited literature available on this subject, the review article aims to sensitize the readers to the diverse interactions of dermatology with the aerospace environment.

  17. Federal Aviation Administration retained savings program proposal

    International Nuclear Information System (INIS)

    Federal legislation allows federal agencies to retain up to 50% of the savings associated with implementing energy efficiency and water conservation measures and practices. Given budget pressures to reduce expenditures, the use of retained savings to fund additional projects represents a source of funds outside of the traditional budget cycle. The Southwest Region Federal Aviation Administration (FAA) has tasked Pacific Northwest National Laboratory (PNNL) to develop a model retained savings program for Southwest Region FAA use and as a prototype for consideration by the FAA. PNNL recommends the following steps be taken in developing a Southwest Region FAA retained savings program: Establish a retained savings mechanism. Determine the level at which the retained savings should be consolidated into a fund. The preliminary recommendation is to establish a revolving efficiency loan fund at the regional level. Such a mechanism allows some consolidation of savings to fund larger projects, while maintaining a sense of facility ownership in that the funds will remain within the region

  1. Considerations of Unmanned Aircraft Classification for Civil Airworthiness Standards

    Maddalon, Jeffrey M.; Hayhurst, Kelly J.; Morris, A. Terry; Verstynen, Harry A.

    2013-01-01

    The use of unmanned aircraft in the National Airspace System (NAS) has been characterized as the next great step forward in the evolution of civil aviation. Although use of unmanned aircraft systems (UAS) in military and public service operations is proliferating, civil use of UAS remains limited in the United States today. This report focuses on one particular regulatory challenge: classifying UAS to assign airworthiness standards. Classification is useful for ensuring that meaningful differences in design are accommodated by certification to different standards, and that aircraft with similar risk profiles are held to similar standards. This paper provides observations related to how the current regulations for classifying manned aircraft, based on dimensions of aircraft class and operational aircraft categories, could apply to UAS. This report finds that existing aircraft classes are well aligned with the types of UAS that currently exist; however, the operational categories are more difficult to align to proposed UAS use in the NAS. Specifically, the factors used to group manned aircraft into similar risk profiles do not necessarily capture all relevant UAS risks. UAS classification is investigated through gathering approaches to classification from a broad spectrum of organizations, and then identifying and evaluating the classification factors from these approaches. This initial investigation concludes that factors in addition to those currently used today to group manned aircraft for the purpose of assigning airworthiness standards will be needed to adequately capture risks associated with UAS and their operations.

    Aviation maintenance was vital for the safety of flight. With the continuing development of civil aviation, the lack of aviation maintenance ability was increasingly serious, so it was necessary to carry out risk management. The SHELL model was taken as the risk identification tool at first. The aviation maintenance risk factors were classified and analyzed in accordance with life (L) factors/Life and life (L-L) factors/ Life and Software (L-S) factors/ Life and Hardware ( L-H) factors/ Life and Environmental factors ( L-E) factors to get the muster of risk factors. Then the fuzzy analytic network process was applied as the tool of risk assessment to quantitatively analyze the importance of risk factors according to the characteristic that risk factors influence each other. Based on the results of risk assessment, the corresponding risk control measures were put forward such as reinforcing maintenance resources management; making the just safety culture; perfecting the construction of the aviation maintenance technicians ; improving the aviation maintenance condition. The result indicated that the study was significant for the aviation maintenance risk management because it could help to systemically identify risk factors, scientifically assess risk factors and make reasonable risk control measures.%机务维修是影响飞行安全的重要环节,随着我国民航业的不断发展,机务维修能力不足的问题日益严重,急需进行风险管理研究.首先选择SHELL模型进行风险因素识别,从人员(L)、人员与人员(L-L)、人员与软件(L-S)、人员与硬件(L-H)、人员与环境(L-E)方面系统的识别出机务维修风险因素;在此基础上,针对机务维修风险因素相互影响的特点,选择模糊网络分析法进行风险评价,得出权重排序;针对评价结果,提出相应的风险控制措施:加强维修资源管理、建立良好的安全文化、强化维修队伍建设、改善维修工作条件.最终结果

The main research trends are also pointed out in the end. The paper provides an overview of the advances of artificial intelligence applied in civil engineering.

  4. Challenges in PFBR civil construction

    International Nuclear Information System (INIS)

    Civil works of PFBR has posed numerous design and construction challenges. Eight safety related nuclear buildings of PFBR are founded on a single raft, first of its kind in Indian nuclear Reactors. Construction of eight interconnected buildings on the common raft has been challenge for construction material transportation. Thus Herculean task, require storage of massive quantities of raw materials and ice. The civil construction scope in PFBR expanded to critical steel fabricated structures integrated with civil works. This includes huge embedment erected to very close tolerances. Large size panels for upper lateral, lower lateral and bottom shields were to be fabricated to intricate contours with tight tolerances and were required to be transported to locations from far off distances; this was well accomplished without loss of tolerances of fabricated structures. Novel construction practices and stringent quality control procedures were implemented to accomplish this critical requirement. Integration of cooling coils inside the safety vessel flanges after completing the reactor vault and safety vessel erection, required special contour bending for numerous reinforcement and development of special construction methodology. The neutron detector box integration with bottom shield was also a construction challenge posed and well addressed by site. Many mock ups were to be carried out for demonstrating the construction procedures and methodology for critical construction activities. Maintaining the stringent requirements such as clean room conditions was a major challenge and was met effectively. Equipment erection in parallel to civil works too required innovative solutions for clean condition maintenance while civil works are in progress. it can be said that the civil construction of PFBR has emerged as a marvel of technology handled professionally by competent engineers deploying scientific construction techniques and stringent quality control procedures.

    Full Text Available Aviation emissions are unique from other transportation emissions, e.g., from road transportation and shipping, in that they occur at higher altitudes as well as at the surface. Aviation emissions of carbon dioxide, soot, and water vapor have direct radiative impacts on the Earth's climate system while emissions of nitrogen oxides (NOx, sulfur oxides, carbon monoxide (CO, and hydrocarbons (HC impact air quality and climate through their effects on ozone, methane, and clouds. The most accurate estimates of the impact of aviation on air quality and climate utilize three-dimensional chemistry-climate models and gridded four dimensional (space and time aviation emissions datasets. We compare five available aviation emissions datasets currently and historically used to evaluate the impact of aviation on climate and air quality: NASA-Boeing 1992, NASA-Boeing 1999, QUANTIFY 2000, Aero2k 2002, and AEDT 2006 and aviation fuel usage estimates from the International Energy Agency. Roughly 90% of all aviation emissions are in the Northern Hemisphere and nearly 60% of all fuelburn and NOx emissions occur at cruise altitudes in the Northern Hemisphere. While these datasets were created by independent methods and are thus not strictly suitable for analyzing trends they suggest that commercial aviation fuelburn and NOx emissions increased over the last two decades while HC emissions likely decreased and CO emissions did not change significantly. The bottom-up estimates compared here are consistently lower than International Energy Agency fuelburn statistics although the gap is significantly smaller in the more recent datasets. Overall the emissions distributions are quite similar for fuelburn and NOx with regional peaks over the populated land masses of North America, Europe, and East Asia. For CO and HC there are relatively larger differences. There are however some distinct differences in the altitude distribution

  18. Aviation in the EU Emissions Trading Scheme. A first step towards reducing the impact of aviation on climate change

    International Nuclear Information System (INIS)

    The European Commission's proposal of September 2005 to include the aviation sector in the EU Emissions Trading Scheme can be seen as a step forward in taking up the aviation sector in climate policy. The environmental impacts of including aviation in the EU-ETS will depend fully on the design of the trading system, with particular emphasis on the total CO2 emission allowances to be determined. In September 2005 the European Commission published its proposal in a Communication on policy instruments to reduce the climate change impacts of aviation. In this MNP report we are addressing Dutch negotiators and members of the Dutch and European parliaments who are not familiar with the details of the policy field with an overview of the main aspects of the policy issue. So far, aviation has not been included in European or international climate policies. However, as the overall climate impact of aviation is estimated at a factor of 2 to 4 higher than the impact of CO2 emissions alone, it is significant enough to be brought forward. If the aviation sector is included in the EU emissions trading system, in the short term the sector is expected to account for carbon emission reductions by purchasing CO2 allowances from other sectors. Impacts on the economy and the environment in the Netherlands are not expected to differ fundamentally from other countries. Kerosene tax and emissions charges may be worthwhile considering, although politically sensitive at international level

    The manifestations of climate change can result in humanitarian impacts that reverse progress in poverty- reduction, create shortages of food and resources, lead to migration, and ultimately result in civil violence and conflict. Within the continent of Africa, we have found that environmentally-related variables are either the cause or the confounding factor for over 80% of the civil violence events during the last 10 years. Using predictive climate models and land-use data, we are able to identify populations in Africa that are likely to experience the most severe climate-related shocks. Through geospatial analysis, we are able to overlay these areas of high risk with assessments of both the local population's resiliency and the region's capacity to respond to climate shocks should they occur. The net result of the analysis is the identification of locations that are becoming particularly vulnerable to future civil violence events (vulnerability hotspots) as a result of the manifestations of climate change. For each population group, over 600 social, economic, political, and environmental indicators are integrated statistically to measures the vulnerability of African populations to environmental change. The indicator time-series are filtered for data availability and redundancy, broadly ordered into four categories (social, political, economic and environmental), standardized and normalized. Within each category, the dominant modes of variability are isolated by principal component analysis and the loadings of each component for each variable are used to devise composite index scores. Comparisons of past vulnerability with known environmentally-related conflicts demonstrates the role that such vulnerability hotspot maps can play in evaluating both the potential for, and the significance of, environmentally-related civil violence events. Furthermore, the analysis reveals the major variables that are responsible for the population's vulnerability and therefore

    The greenhouse gas emissions of international aviation and maritime transport are projected to increase rapidly over the coming decades, despite significant improvements in the fuel efficiency of aircraft and ships. In order to address their growth, Market Based Measures (MBMs) have been proposed to complement technical and operational measures. These measures are being discussed in ICAO (the UN organization for civil aviation) and IMO (the UN organization for maritime transport). One of the main issues in the debate has been the impact of MBMs on developing countries and especially on remote economies. This report quantifies the economic impacts of MBMs on ten case study economies and globally. The case study economies have been selected in the expectation that they would be relatively highly impacted because of their remoteness and/or dependence on international aviation or maritime transport. This report shows that the decrease in GDP is less than 0.01% on average and significantly less than 0.1% for all but a few of the case study countries. Countries with a higher dependency on tourism and trade are likely to experience greater economic impacts as market-based measures raise the costs of aviation and maritime transport; they impact economies due to increased prices for passenger travel and exported and imported goods. Some of these countries are small island states that are also vulnerable to climate change impacts. Undesired economic impacts on developing countries can be addressed effectively by a combination of measures such as exemptions of certain routes, lump sum rebates, and investments in infrastructure efficiency and development of more efficient ships and aircraft.

  2. The rebound effect in the aviation sector

    International Nuclear Information System (INIS)

    The rebound effect, i.e., the (partial) offset of the energy efficiency improvement potential due to a reduction in marginal usage costs and the associated increase in consumer demand, has been extensively studied for residential energy demand and automobile travel. This study presents a quantitative estimate of the rebound effect for an air traffic network including the 22 busiest airports, which serve 14 of the highest O–D cities within the domestic U.S. aviation sector. To satisfy this objective, passenger flows, aircraft operations, flight delays and the resulting energy use are simulated. Our model results indicate that the average rebound effect in this network is about 19%, for the range of aircraft fuel burn reductions considered. This is the net impact of an increase in air transportation supply to satisfy the rising passenger demand, airline operational effects that further increase supply, and the mitigating effects of an increase in flight delays. Although the magnitude of the rebound effect is small, it can be significant for a sector that has comparatively few options for reducing greenhouse gas emissions. - Highlights: ► We estimate the rebound effect for an air traffic network of 22 airports in the US. ► Passenger flows, aircraft operations, flight delays and energy use are simulated. ► Our model results indicate that the rebound effect in this network is about 19%. ► This is primarily due to an increase in flights to satisfy rising passenger demand

    Multivariate Time-Series (MTS) are ubiquitous, and are generated in areas as disparate as sensor recordings in aerospace systems, music and video streams, medical monitoring, and financial systems. Domain experts are often interested in searching for interesting multivariate patterns from these MTS databases which can contain up to several gigabytes of data. Surprisingly, research on MTS search is very limited. Most existing work only supports queries with the same length of data, or queries on a fixed set of variables. In this paper, we propose an efficient and flexible subsequence search framework for massive MTS databases, that, for the first time, enables querying on any subset of variables with arbitrary time delays between them. We propose two provably correct algorithms to solve this problem (1) an R-tree Based Search (RBS) which uses Minimum Bounding Rectangles (MBR) to organize the subsequences, and (2) a List Based Search (LBS) algorithm which uses sorted lists for indexing. We demonstrate the performance of these algorithms using two large MTS databases from the aviation domain, each containing several millions of observations Both these tests show that our algorithms have very high prune rates (>95%) thus needing actual

  4. Dosimetry at aviation altitudes (2006-2008)

    International Nuclear Information System (INIS)

    Based upon the European Union (EU)-Directive 96/29/EURATOM, legal regulations on the radiation protection of aircrew had to be implemented into the corresponding national law within the member states of the EU by 13 May 2000. In Article 42 the directive stipulates, among other things, that the exposure of the crew concerned shall be assessed. This requirement has been implemented by dose calculations for most aircrew members in the EU. Some airlines and research institutes regularly spot check the calculated doses by measuring flights. The solar minimum is a time period of particular interest since the dose rates at aviation altitudes reach their maximum within the 11-year solar cycle. For this reason, the German Aerospace Center (DLR) performed repeated measuring flights in cooperation with several German airlines during the past solar minimum from March 2006 to August 2008. The measuring devices used consisted of a tissue equivalent proportional counter, various types of Liulin semiconductor detectors and several bubble detectors. (authors)

  5. Sustainability Reporting in the Aviation sector

    Energy Technology Data Exchange (ETDEWEB)

    Katherine Miles Hill [Global Reporting Initiative (Netherlands)

    2008-09-30

    The Global Reporting Initiative (GRI) G3 Guidelines are the de-facto standard for sustainability reporting. Thousands of organizations around the world base their annual sustainability report on the GRI G3 Guidelines, including many within the aviation sector, including leading airports, aerospace manufacturers and airlines. The Guidelines are principles based and contain Disclosures on Management Approach and Performance Indicators. To report on the performance indicators a company needs to measure and manage its entities. By doing so targets can be set to improve performance over the years, on sustainability topics ranging from community investment to CO{sub 2} emissions. Each company is different and therefore each company needs to conduct a materiality test to assess which indicators to use, based on Stakeholder Assessments and Decisions and Significance of Economic, Environmental and Social Impacts. Using the Guidelines means that you have a tool for clear and comparable communication with your stakeholders and measuring your performance on sustainability topics like CO{sub 2} emissions. By measuring CO{sub 2} emissions overtime in a uniform way and publishing the emissions in your sustainability report, your stakeholders will appreciate your honesty and better understand when you experience difficulties in meeting your targets to limit the emissions. Additionally it will allow you to be able to benchmark your company against other companies in your sector.

  6. Asymptotic procedures for aviation constructions calcul

    International Nuclear Information System (INIS)

    Theory of elasticity equations for statics, dynamics, stability of aviation constructions are very complex and very difficult to decide. To get the solution engineers pass on to the applied theories -- ones of bars, plates, shells. In this case some hypothesises are input. A quantity of the ones in vague, and its might be excessive and even contradicting. In this work some procedures permitting to establish the necessary and sufficient quantity of hypothesises, estimating each member contribution into equation, throwing off secondary members and keeping of principals. For example, in such a manner all without exception applied theories of bar, plates and shells are obtained from three-dimensional theory of elasticity. The fact is interesting that all the theories are obtained on a basis of the mapping contracting principle. The proposed approach essence is contained in that some small parametres are singled out of the input equations and the ones are rewritten in the suitable aspect small parametre to the some power value is attached to the symbols of differentiation. This unknown power is determined from the condition of coincidence of the starting approximation, power with the one of the first approximation. As the first example the problem for the unit width long rectangular strip with the fixed short edges (x=1,1) and the free longitudinal edges (y=+1, -1) is considered. The longitudinal edges are loaded with some distributed charge

  7. Refining and blending of aviation turbine fuels.

    White, R D

    1999-02-01

    Aviation turbine fuels (jet fuels) are similar to other petroleum products that have a boiling range of approximately 300F to 550F. Kerosene and No.1 grades of fuel oil, diesel fuel, and gas turbine oil share many similar physical and chemical properties with jet fuel. The similarity among these products should allow toxicology data on one material to be extrapolated to the others. Refineries in the USA manufacture jet fuel to meet industry standard specifications. Civilian aircraft primarily use Jet A or Jet A-1 fuel as defined by ASTM D 1655. Military aircraft use JP-5 or JP-8 fuel as defined by MIL-T-5624R or MIL-T-83133D respectively. The freezing point and flash point are the principle differences between the finished fuels. Common refinery processes that produce jet fuel include distillation, caustic treatment, hydrotreating, and hydrocracking. Each of these refining processes may be the final step to produce jet fuel. Sometimes blending of two or more of these refinery process streams are needed to produce jet fuel that meets the desired specifications. Chemical additives allowed for use in jet fuel are also defined in the product specifications. In many cases, the customer rather than the refinery will put additives into the fuel to meet their specific storage or flight condition requirements. PMID:10189575

    Hugh Collins argues that the European Union should develop a civil code to provide uniform rules for contracts, property rights and protection against civil wrongs, thus drawing together the differing national traditions with respect to the detailed regulation of civil society. The benefits of such a code would lie not so much in facilitating cross border trade, but in establishing foundations for a denser network of transnational relations of civil society, which in turn would help to overco...

  12. Investment Strategy Based on Aviation Accidents: Are there abnormal returns?

    Directory of Open Access Journals (Sweden)

    Marcos Rosa Costa

    2013-06-01

    Full Text Available This article investigates whether an investment strategy based on aviation accidents can generate abnormal returns. We performed an event study considering all the aviation accidents with more than 10 fatalities in the period from 1998 to 2009 and the stock market performance of the respective airlines and aircraft manufacturers in the days after the event. The tests performed were based on the model of Campbell, Lo & MacKinlay (1997 for definition of abnormal returns, by means of linear regression between the firms’ stock returns and the return of a market portfolio used as a benchmark. This enabled projecting the expected future returns of the airlines and aircraft makers, for comparison with the observed returns after each event. The result obtained suggests that an investment strategy based on aviation accidents is feasible because abnormal returns can be obtained in the period immediately following an aviation disaster.

  15. Estimated revenues of VAT and fuel tax on aviation

    Energy Technology Data Exchange (ETDEWEB)

    Korteland, M.; Faber, J.

    2013-07-15

    International aviation is exempt from VAT, both on their inputs (e.g. on fuel or aircraft) and on their revenues (e.g. on tickets). In the EU, aviation fuel is also exempt from the minimum fuel excise tariffs. This report calculates the potential revenues of VAT on tickets and fuel tax on jet fuel. If VAT were to be levied on tickets while other aviation taxes were simultaneously abolished, this would yield revenues in the order of EUR 7 billion. Excise duty on jet fuel would raise revenues in the order of EUR 20 billion. These figures do not take into account the impact of the cost increases on demand for aviation into account. Since higher costs will reduce demand, the estimates can be considered an upper bound.

  19. 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

  8. Determination of service life of aviation lubricants

    Energy Technology Data Exchange (ETDEWEB)

    Kuznetsov, V.G.; Novosartov, G.T.; Echin, A.I.; Bakunin, V.N.

    1985-11-01

    A method of evaluating the quality of expensive lubricants was developed based on determination of thermo-oxidative stability on a TSM-1 apparatus. This allowed measurement of the content of additives and qualitative properties associated with them during oxidation under laboratory conditions. By developing graphs showing dependence of operating properties sharply degrade was determined. This minimum additive content became the criterion for assessing the working capability of the lubricant and determining the limiting length of its service. Thus, for lubricant B-3V, the most important operating characteristics are thermooxidative stability and critical loading. Samples were tested for the additives PODFA and kaptaks and for indicators of antioxidative and antiseizing properties. Experiments showed little change in characteristics during 10 h of oxidation. Laboratory tests showed that the critical loading began to drop when the kaptaks level fell below 0.2%, so this was taken as the minimal acceptable level. Similarly, for lubricant IPM-10, the most important operating property is its thermo-oxidative stability. Tests showed that indicators of thermo-oxidative stability all began to fall when the antioxidative additive fell below 0.1%. This approach allows rapid determination of service criteria for any aviation lubricant with critical additives. In a practical test, B-3V lubricant had been changed in the MI-8 helicopter every 200-300 h, although its kaptaks level was still 0.65%; even at 900 hours it had fallen to only 0.36%. This would allow the service life to be tripled, a conclusion verified by determination of physicochemical and operating properties of the lubricant at that point. 4 references, 2 figures.

  9. Challenges in PFBR civil construction

    International Nuclear Information System (INIS)

    Civil works of PFBR has posed numerous design and construction challenges. Eight safety related nuclear buildings of PFBR are founded on a single raft, first of its kind in Indian nuclear Reactors. Construction of eight interconnected buildings on the common raft has been challenge for construction material transportation. The construction of Nuclear Island Connected Buildings (NICB) raft was completed in three and a half months. This massive 100mx100m raft for NICB, requiring 35000 cubic meter of concrete was undertaken in twelve pours. This Herculean task required storage of massive quantities of raw materials and ice. The construction of Turbo Generator (TG) building including TG mat and deck and interconnection with NICB posed enormous construction challenges that were well planned and executed. The intake and outfall structures too are exemplary construction handled effectively at PFBR. The excavation for the nuclear and power islands was large and deep. Rock out crops were found starting at various depths of excavation, requiring extensive planning controlled blasting and mechanization in excavation. This also required innovative dewatering procedures in sandy terrain often mixed with clay. Ground water table at PFBR site being high, water proofing for massive underground structure of PFBR was required to be carefully engineered and handled. This started with innovative grouting of excavated strata below the raft till required permeability was met and bone dry condition was achieved for laying of waterproofing membranes. Concurrent construction and regulatory reviews and stage wise clearance for civil construction required dynamic construction planning and sequencing. The scope of civil construction in PFBR expands to critical steel fabricated structures integrated with civil works. This includes huge embedment erected to very close tolerances. Large size panels for upper lateral, lower lateral and bottom shields were fabricated to intricate contours with

  13. Domesticating the Drone: The Demilitarisation of Unmanned Aircraft for Civil Markets.

    Boucher, Philip

    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.

  2. Civil Applications of Safeguards Equipment

    International Nuclear Information System (INIS)

    The events of September 11 have cast a new light on the perceived security of the world's nuclear facilities. Although concerns have persisted that governments might want to divert nuclear material from civil use to secret weapons programs - recent developments in North Korea validate such concerns - the terrorist attacks on US soil have inspired new fears for nuclear sites of insider threats that, if acted upon, could result in either outright sabotage of the facility or diversion of materials, potentially for future terrorist activities. Further, these concerns have increased the importance of preventing material stolen from nuclear facilities in countries with relatively weak security measures from being trafficked illicitly to and used against prime terrorist targets (industrialized countries of Europe and North America). Without international agreements and standards to guide their efforts, the international nonproliferation community now faces these newly emerged challenges of how to protect nuclear materials from insider threats and how to block diverted materials from reaching terrorist hands. The following paper will explore opportunities for agreed-upon and proven integrated safeguards equipment to be used both to counter the insider threat at nuclear facilities by automatically supervising oversight authorities, and to prevent illicit trafficking of nuclear materials by observing personnel and procedures at civil installations. To conclude, the paper will look to future civil applications of safeguards equipment as support for international counter-terrorism and security efforts

    1981-01-01

    Studies carried out within the last ten years on the nature and distribution of extraterrestrial intelligent life are reviewed. Arguments for the absence of intelligent life in the Galaxy based on the assumption that at least some of these would have engaged in colonization and for the presence of colonies of extraterrestrials in some undiscovered location in the solar system are presented, and it is noted that both these views rest on the notion that interstellar travel can be achieved at high velocities in very large vehicles, which has been questioned. Alternative suggestions concerning interstellar exploration by automated probes and the possible extended time scale and motivation for galactic colonization are pointed out. Attention is then given to arguments for the extreme smallness of one of the factors in the Drake equation used to estimate the number of communicative extraterrestrial civilizations in the Galaxy, including the frequency of single stars, the likelihood that planets with the correct initial composition and conditions for life are at the proper distance from their stars, the probability of the formation of DNA and the origin of life, and the time for the evolution of intelligence. It is concluded that it seems likely that other civilizations exist in the Galaxy, although the number and distribution of such civilizations may only be determined by the detection of one or more examples.

    Turney, Mary Ann; Bishop, James C.; Karp, Merrill R.; Niemczyk, Mary; Sitler, Ruth L.; Green, Mavis F.

    2002-01-01

    Since the numbers of women pursuing technical careers in aviation continues to remain very low, a study on retention of women was undertaken by a team of university faculty from Embry Riddle Aeronautical University, Arizona State University, and Kent State University. The study was initiated to discover the factors that influence women once they have already selected an aviation career and to ascertain what could be done to support those women who have demonstrated a serious interest in an aviation career by enrolling in a collegiate aviation program. This paper reports preliminary results of data collected in the first and second years of the study. The data was collected from surveys of 390 college students (195 women and 195 men) majoring in aviation programs in nine colleges and universities, representing widely varied geographic areas and including both two- and four-year institutions. Results revealed significant areas of concern among women in pilot training. When queried about these concerns, differences were evident in the responses of the male and female groups. These differences were expected. However, a surprising finding was that women in early stages of pilot training responded differently from women in more experienced stages, These response differences did not occur among the men surveyed. The results, therefore, suggest that women in experienced stages of training may have gone through an adaptation process and reflect more male-like attitudes about a number of objects, including social issues, confidence, family, and career.

  5. Science in Support of Aviation-Risk Management since the April 2010 Eruption of Eyjafjallajökull, Iceland

    Science.gov (United States)

    Guffanti, M.; Mastin, L. G.; Schneider, D. J.; Tupper, A.

    2010-12-01

    The nearly week-long airspace closure over large parts of Europe and the North Atlantic in April 2010 that resulted from dispersion of ash from the eruption of Eyjafjallajökull prompted a shift from the accepted global policy of strict avoidance by aircraft of ash-contaminated airspace to one of allowing flight through zones of dilute ash under some circumstances. This shift was made in a crisis environment of rapidly mounting economic losses and social disruptions extending well beyond the European region. To get the global air transportation system moving again, European aviation authorities and associated meteorological offices created a new type of advisory product depicting forecasted zones of low ash concentrations in Eyjafjallajökull’s clouds that could be transited with expectation of no or minimal risk of aircraft damage, under the condition of more frequent aircraft inspections and enhanced risk management by airlines. Preliminary data of the European Aviation Safety Agency indicate that transit through Eyjafjallajökull’s dilute ash clouds caused some wear (primarily abrasion) to a few aircraft, but not to the severity of degraded engine performance in flight; after inspections the aircraft were returned to service and continued to operate without problems. Following the crisis, recognizing that such a fundamental shift in risk management requires sound scientific and engineering bases, the International Civil Aviation Organization (ICAO) formed an International Volcanic Ash Task Force that, in conjunction with the World Meteorological Organization (WMO), will incorporate advice and recommendations from scientific, aviation, and engineering experts worldwide about ways to improve (1) situational awareness to aviation users of impending volcanic eruptions, (2) characterization of critical eruption source parameters for incorporation in forecast modeling, (3) detection and characterization of volcanic clouds, (4) accuracy of volcanic ash transport

  9. Human-Centered Aviation Automation: Principles and Guidelines

    Science.gov (United States)

    Billings, Charles E.

    1996-01-01

    This document presents principles and guidelines for human-centered automation in aircraft and in the aviation system. Drawing upon operational experience with highly automated aircraft, it describes classes of problems that have occurred in these vehicles, the effects of advanced automation on the human operators of the aviation system, and ways in which these problems may be avoided in the design of future aircraft and air traffic management automation. Many incidents and a few serious accidents suggest that these problems are related to automation complexity, autonomy, coupling, and opacity, or inadequate feedback to operators. An automation philosophy that emphasizes improved communication, coordination and cooperation between the human and machine elements of this complex, distributed system is required to improve the safety and efficiency of aviation operations in the future.

    Science.gov (United States)

    Prather, C. Daniel

    2007-01-01

    The Council on Aviation Accreditation (CAA) was established in 1988 in response to the need for formal, specialized accreditation of aviation academic programs, as expressed by institutional members of the University Aviation Association (UAA). The first aviation programs were accredited by the CAA in 1992, and today, the CAA lists 60 accredited programs at 21 institutions nationwide. Although the number of accredited programs has steadily grown, there are currently only 20 percent of UAA member institutions with CAA accredited programs. In an effort to further understand this issue, a case study of the CAA was performed, which resulted in a two-part case study report. Part one addressed the historical foundation of the organization and the current environment in which the CAA functions. Part two focuses on the following questions: (a) what are some of the costs to a program seeking CAA accreditation (b) what are some fo the benefits of being CAA accredited; (c) why do programs seek CAA accreditation; (d) why do programs choose no to seek CAA accreditation; (e) what role is the CAA playing in the international aviation academic community; and (f) what are some possible strategies the CAA may adopt to enhance the benefits of CAA accreditation and increase the number of CAA accredited programs. This second part allows for a more thorough understanding of the contemporary issued faced by the organization, as well as alternative strategies for the CAA to consider in an effort to increase the number of CAA accredited programs and more fully fulfill the role of the CAA in the collegiate aviation community.

  19. SHM reliability and implementation - A personal military aviation perspective

    Science.gov (United States)

    Lindgren, Eric A.

    2016-02-01

    Structural Health Monitoring has been proposed as a solution to address the needs of military aviation to reduce the time and cost to perform nondestructive inspections. While the potential to realize significant benefits exist, there are considerations that have to be addressed before such systems can be integrated into military platforms. Some considerations are pervasive to all aviation, such as how to assess the reliability and reproducible capability of these systems. However, there are other challenges unique to military aviation that must be overcome before these types of systems can be used. This presentation and paper are intended as a complement to the review of the outcome of the SAE G-11 SHM committee special workshop on SHM reliability in April of 2015. It will address challenges unique to military aviation that stem from different approaches to managing structural integrity (i.e. safety), frequency of use, design differences, various maintenance practices, and additional descriptions addressing differences in the execution of inspections. The objective of this presentation is to improve the awareness of the research and development community to the different and unique requirements found in military aviation, including the differences between countries, services, and aircraft type. This information should assist the research and development community in identifying and attacking key challenges. It is not intended to be comprehensive overview of all stakeholders' perspectives, but to serve as a launch point for additional discussion and exploration of opportunities to realize the potential of Structural Health Monitoring to assist in the management of military aviation assets. The views expressed in this publication are those of the author and do not reflect the official policy or position of the United States Air Force, Department of Defense, or the United States Government.

    2012-05-01

    Full Text Available We debated in this article the civil liability for environmental damages as stipulated in ourlegislation with reference to Community law. The theory of legal liability in environmental law is basedon the duty of all citizens to respect and protect the environment. Considering the importance ofenvironment in which we live, the liability for environmental damages is treated by the Constitution as aprinciple and a fundamental obligation. Many human activities cause environmental damages and, in linewith the principle of sustainable development, they should be avoided. However, when this is notpossible, they must be regulated (by criminal or administrative law in order to limit their adverse effectsand, according to the polluter pays principle, to internalize in advance their externalities (through taxes,insurances or other forms of financial security products. Communication aims to analyze these issues andlegal regulations dealing with the issue of liability for environmental damage.

    International Nuclear Information System (INIS)

    The technical requirements for the radiation meters used in civil defence are specified in the guide. The aim of the requirements is to quarantee sufficient measurement accuracy and reliable operation even in extreme environmental conditions. The guide is based on the following standards: (1) IEC 846 'Beta, X and gamma radiation dose equivalent and dose equivalent rate meters for use in radiation protection', (2) IEC 1017-1 'Portable, transportable of installed X or gamma radiation ratemeters for environmental monitoring, part 1: Ratemeters', and (3) IEC 45 B (Secretariat) 104 'Direct reading, personnel dose equivalent and/or dose equivalent rate monitors for X, gamma and high energy beta radiation'.

  12. Civil defense should be mandatory

    International Nuclear Information System (INIS)

    In this paper, the author exposes myths about the effects of nuclear weapons so that the U.S. can begin the necessary task of a mandatory civil defense program. An all-out nuclear war between Russia and the United States would be the worst catastrophe in history, a tragedy so huge it is difficult to comprehend. Even so, it would be far from the end of human life on earth. The dangers from nuclear weapons have been distorted and exaggerated for varied reasons. These exaggerations have become demoralizing myths, believed by millions of Americans. The author has found that many people see no sense in talking about details of survival skills. Only after they have begun to question the truth of these myths do they become interested, under normal peacetime conditions, in acquiring nuclear war survival skills. The author examines the most harmful of the myths about nuclear war dangers, along with some of the grim facts

  4. Aviation safely management, Valdez oil spill clean-up

    International Nuclear Information System (INIS)

    The March 24, 1989 Exxon Valdez oil spill in Alaska's Prince William Sound (PWS) resulted in an unprecedented mobilization of personnel and oil spill clean-up equipment. This paper describes the comprehensive safety management system implemented for aviation operations supporting the clean-up response in PWS and the Gulf of Alaska (GOA). Aviation support operations quickly expanded to over 100 aircraft obtained from numerous sources. Beginning with early surveillance flights, aviation operations were subject to comprehensive safety management programs, including safety assessments, minimum flight weather criteria, operational standards and procedures, air carrier qualifications, equipment and procedure audits, and emergency response. Communication networks and flight following procedures were established, arctic survival training was conducted, and a full complement of survival equipment was required. These programs were largely responsible for safety performance of the spill response effort-during the 1989-92 response activities, over 56,000 flight hours, 159,000 equivalent passengers, and 20,000 tons of cargo were handled without an aviation related injury. The programs are applicable to offshore development and operational activities, particularly those located in more remote, severe environments
