    It has been suggested that exposure to high-noise levels near major airports may cause increased incidence of birth defects in the offspring of parents residing near these airports. Using data gathered in Metropolitan Atlanta during 1970 to 1972, we compared the rates of seventeen categories of defects in high- and low-noise census tracts. No significant differences were observed. However, when we subdivided the category of central nervous system defects into several subcategories of specific defects, we noted a significantly increased incidence of spina bifida without hydrocephalus in the high-noise areas. Because of the small number of cases associated with this finding we did a matched case-control study using all cases of central nervous system defects born during the years 1968 to 1976. No significantly increased risk for residents in the high-noise areas was noted in this study. It is our opinion that noise or other factors associated with residence near airports are unlikely to be important environmental teratogens.

    Full Text Available Purpose: On the topic of sustainable aviation a study was carried out to measure the difference between the actual change in air traffic noise and the airport’s residents’ perception of the noise change at Vienna International Airport. Therefore, a questionnaire was developed in cooperation with the airport and an online survey was conducted. Design/methodology/approach: For the survey of the opinion of the affected population of the surrounding communities, a web based online questionnaire is created and distributed via various channels including e-mail, and online forums. After the basic structure of the questionnaire had been defined, the questions were developed in cooperation with employees form the environmental department of VIE, who had a sustainable influence on the questions’ order and formulation. As the survey was supposed to be answered by residents around VIE. Findings: Results of the online study show that only parts of the participants are affected by air traffic noise at VIE. Even less experienced a significant change over the last five years. About one third of the participants stated that they are affected by air traffic noise in one way or another. The majority of these people live in Lower Austria, the federal state in which the airport is located. The participants obviously judge air traffic noise during day time more importantly than air traffic noise at night. Research limitations/implications: Due to the low number of returns, no statistically relevant conclusions can be drawn, the results of the survey can be used to make some general statements. Originality/value: Economic growth and deregulation lead to growing aircraft operations. Vienna International Airport with its approximately 260,000 flight movements per year is the biggest airport in Austria and a major hub in Europe. The combination of constantly growing air transport and the resulting noise exposure, as well as the steadily increasing

    Full Text Available There have always been conflicts among airports and local communities due to the aeronautical noise generated by airport operations. In fact, this is a factor that - if not properly managed - could severely cut down the growth of air traffic in an airport with direct effects on the economic and territorial system. Beside this, in the last decade the critical issues related to the impact of aeronautical noise on airport operations have greatly reduced, thanks to technological improvements in aircraft design. Nevertheless, the reduction of noise emissions during a single aircraft operation does not make the issue of the airports’ location less important. This is the case of regional airports in EU, which have recently experimented a large traffic increase due to the development of low-cost traffic. It is now clear that the problem cannot be reduced to its mere technological aspect, but it ought to be dealt with the involvement of the various stakeholders in order to mitigate the emissions and adequately compensate the impacts to local communities. Typically, there are two possible countermeasures to mitigate the effects of aircraft noise: operational measures, based on the application of technological and organizational devices and market-based measures. The application of noise taxes, aiming at compensating the negative externalities generated by airport operations is becoming increasingly widespread in EU. In this paper, a methodology for the application of noise taxes based on the actual noise of aircraft operating into an airport is discussed and implemented in a test case.

  4. Airport Noise Tech Challenge Overview

    2011-01-01

    The Supersonics Project, operating under NASA Aeronautics Mission Directorate#s Fundamental Aero Program, has been organized around the Technical Challenges that have historically precluded commercial supersonic flight. One of these Challenges is making aircraft that are capable of such high aerodynamic performance quiet enough around airports that they will not be objectionable. It is recognized that a successful civilian supersonic aircraft will be a system where many new technologies will come together, and for this to happen not only will new low noise propulsion concepts be required, but new engineering tools that predict the noise of the aircraft as these technologies are combined and compromised with the rest of the aircraft design. These are the two main objectives of the Airport Noise Tech Challenge. " ! As a Project in the Fundamental Aero Program, we work at a relatively low level of technology readiness. However, we have high level milestones which force us to integrate our efforts to impact systems-level activities. To keep the low-level work tied to delivering engineering tools and low-noise concepts, we have structured our milestones around development of the concepts and organized our activities around developing and applying our engineering tools to these concepts. The final deliverables in these milestones are noise prediction modules validated against the best embodiment of each concept. These will then be used in cross-disciplinary exercises to demonstrate the viability of aircraft designs to meet all the Technical Challenges. Some of the concepts being developed are shown: Fan Flow Diverters, Multi-jet Shielding, High-Aspect Ratio Embedded Nozzles, Plasma Actuated Instability Manipulation, Highly Variable Cycle Mixer- Ejectors, and Inverted Velocity Profiles. These concepts are being developed for reduced jet noise along with the design tools which describe how they perform when used in various aircraft configurations. Several key upcoming

    Full Text Available ABSTRACT OBJECTIVE To perform a quantitative analysis of the background noise at Congonhas Airport surroundings based on large sampling and measurements with no interruption. METHODS Measuring sites were chosen from 62 and 72 DNL (day-night-level noise contours, in urban sites compatible with residential use. Fifteen sites were monitored for at least 168 hours without interruption or seven consecutive days. Data compilation was based on cross-reference between noise measurements and air traffic control records, and results were validated by airport meteorological reports. Preliminary diagnoses were established using the standard NBR-13368. Background noise values were calculated based on the Sound Exposure Level (SEL. Statistic parameters were calculated in one-hour intervals. RESULTS Only four of the fifteen sites assessed presented aircraft operations as a clear cause for the noise annoyance. Even so, it is possible to detect background noise levels above regulation limits during periods of low airport activity or when it closes at night. CONCLUSIONS All the sites monitored showed background noise levels above regulation limits between 7:00 and 21:00. In the intervals between 6:00-6:59 and 21:00-22:59 the noise data, when analyzed with the current airport operational characteristics, still allow the development of additional mitigating measures.

    In a survey of 2,312 residents living near Frankfurt Airport aircraft noise annoyance and disturbances as well as environmental (EQoL) and health-related quality of life (HQoL) were assessed and compared with data on exposure due to aircraft, road traffic, and railway noise. Results indicate higher noise annoyance than predicted from general exposure-response curves. Beside aircraft sound levels source-related attitudes were associated with reactions to aircraft noise. Furthermore, aircraft noise affected EQoL in general, although to a much smaller extent. HQoL was associated with aircraft noise annoyance, noise sensitivity and partly with aircraft noise exposure, in particular in the subgroup of multimorbid residents. The results suggest a recursive relationship between noise and health, yet this cannot be tested in cross-sectional studies. Longitudinal studies would be recommendable to get more insight in the causal paths underlying the noise-health relationship. PMID:20948931

    1985-01-01

    Sources of information about noise environments at different times of the day at civilian and military airports are identified. Information about movements of scheduled flights are available in machine readable form from the Official Airline Guide. Information about permanent noise monitoring sites is readily obtained from individual airports. Limited data on the timing of flights are available at centralized locations for military airports. An examination of scheduled flights at commercial airports leads to the conclusion that differences between daytime and nighttime noise levels (measured in Equivalent Continuous Noise Level, LEQ) vary from 7 to 15 decibels. Data from 128 permanent noise monitoring sites at 11 airports are also examined. Differences between daytime and nighttime noise levels at these 128 noise monitoring sites vary from 3 to 17 decibels (LEQ). Preliminary analyses suggest that accurate estimates of time-of-day weights could not be obtained from conventional social surveys at existing airports.

    ZHANG Bang-jun; GUO Chun-yan; Di Guo-qing

    2004-01-01

    Noise contours are used to describe the extent of airport noise pollution and to plan land use around airports. The LwEcPN (weighted equivalent continuous perceive noise level) recommended by ICAO(International Civil Aviation Organization ) is adopted as airport noise rating parameter in this paper. With the help of various mathematical models in the software Surfer, noise contours can be drawn automatically by the completed program in Visual C++ Code. Corrections for thrust, velocity, atmospheric temperature, humidity and lateral ground attenuation are also considered in the new method, which can improve the efficiency of drawing contours. An example of its use for drawing noise contours of an airport in Zhejiang Province of China is proposed and the predictions and the measurements show agreements well.

  9. On Physical Aeroacoustics with Some Implications for Low-Noise Aircraft Design and Airport Operations

    Directory of Open Access Journals (Sweden)

    Luís M. B. C. Campos

    2015-02-01

    Full Text Available Air traffic is growing at a steady rate of 3% to 5% per year in most regions of the world, implying a doubling every 15–25 years. This requires major advances in aircraft noise reduction at airports, just not to increase the noise exposure due to the larger number of aircraft movements. In fact it can be expected, as a consequence of increased opposition to noise by near airport residents, that the overall noise exposure will have to be reduced, by bans, curfews, fines, and other means and limitations, unless significantly quieter aircraft operations are achieved. The ultimate solution is aircraft operations inaudible outside the airport perimeter, or noise levels below road traffic and other existing local noise sources. These substantial noise reductions cannot come at the expense of a degradation of cruise efficiency, that would affect not just economics and travel time, but would increase fuel consumption and emission of pollutants on a global scale. The paper reviews the: (i current knowledge of the aircraft noise sources; (ii the sound propagation in the atmosphere and ground effects that determine the noise annoyance of near-airport residents; (iii the noise mitigation measures that can be applied to current and future aircraft; (iv the prospects of evolutionary and novel aircraft designs towards quieter aircraft in the near term and eventually to operations inaudible outside the airport perimeter. The 20 figures and 1 diagram with their legends provide a visual summary of the review.

    Airport noise and its impact on the surrounding areas are major issues in the aviation industry. The İstanbul Atatürk Airport is a major global airport with passenger numbers increasing rapidly per annum. The noise levels for day, evening and night times were modeled around the İstanbul Atatürk Airport according to the European Noise Directive using the actual data records for the year 2011. The "ECAC Doc. 29-Interim" method was used for the computation of the aircraft traffic noise. In the setting the noise model for the local airport topography was taken into consideration together with the noise source data, the airport loadings, features of aircraft and actual air traffic data. Model results were compared with long-term noise measurement values for calibration. According to calibration results, classifications of the aircraft type and flight tracks were revised. For noise model validation, the daily noise measurements at four additional locations were used during the verification period. The input data was re-edited only for these periods and the model was validated. A successful model performance was obtained in several zones around the airport. The validated noise model of the İstanbul Atatürk Airport can be now utilized both for determining the noise levels in the future and for producing new strategies which are about the land use planning, operational considerations for the air traffic management and the noise abatement procedures.

    The Fraction Impact Method (FIM), developed by the National Research Council (NRC) for assessing the amount and physiological effect of noise, is described. Here, the number of people exposed to a given level of noise is multiplied by a weighting factor that depends on noise level. It is pointed out that the Aircraft-noise Levels and Annoyance MOdel (ALAMO), recently developed at NASA Langley Research Center, can perform the NRC fractional impact calculations for given modes of operation at any U.S. airport. The sensitivity of these calculations to errors in estimates of population, noise level, and human subjective response is discussed. It is found that a change in source noise causes a substantially smaller change in contour area than would be predicted simply on the basis of inverse square law considerations. Another finding is that the impact calculations are generally less sensitive to source noise errors than to systematic errors in population or subjective response.

    Aircraft noise perception is related to several variables that are tangible and objective, such as the number of operations, flight schedules. Other variables, instead, are more subjective, such as preferences. However, although their elusiveness, they contribute to determine the individuals' perception of this type of externality. Despite the fact that the complaints related to aeronautical noise have been registered since the decade of 50, it has been observed that the perception of noise seems to have grown, especially since the 80's. It has been argued that this change in noise perception has its roots on the accelerated expansion of air traffic. But, it is necessary to point out the important role played on modeling preferences, by the growing environmental conscience and the higher welfare and quality of life standards and expectations. In that context, the main objective of this paper is to study the aeronautical noise perception in the neighborhoods of the Aeroporto Internacional de Sao Paulo - AISP (the biggest airport of South America). Specifically, it analyzes the relationship between aircraft noise perception and social class, which is expected to be positive. Since noise perception is an intangible variable, this study chose as a proxy the value losses of residential properties, caused by aeronautical noise. The variable social class has been measured utilizing average per capita income of the population who live nearby the airport. The comparison of both, the lowest and the highest social class suggests that the relationship between social class and noise perception is positive in the AISP region. Moreover, it was observed that all social classes are very susceptible to aircraft noise annoyance. In fact, the magnitude of the noise perception proxy for both social classes -the residential value losses- was found to be comparable to levels encountered in developed countries.

    The level of aircraft noise exposure around İstanbul Atatürk Airport was calculated according to the European Noise Directive. These calculations were based on the actual flight data for each flight in the year 2011. The study area was selected to cover of 25km radius centered on the Aerodrome Reference Point of the airport. The geographical data around İstanbul Atatürk Airport was used to prepare elevation, residential building, auxiliary building, hospital and school layers in SoundPlan software. It was found that 1.2% of the land area of İstanbul City exceeds the threshold of 55dB(A) during daytime. However, when the exceedance of threshold of 65dB(A)is investigated, the affected area is found quite small (0.2% of land area of city). About 0.3% of the land area of İstanbul City has noise levels exceeding 55dB(A) during night-time. Our results show that about 4% of the resident population was exposed to 55dB(A) or higher noises during daytime in İstanbul. When applying the second threshhold criteria, nearly 1% of the population is exposed to noise levels greater than 65dB(A). At night-time, 1.3% of the population is exposed to 55dB(A) or higher noise levels.

      机场噪声预测对机场噪声控制、航班计划制定和机场规划设计具有十分重要的作用.现有的机场噪声预测模型都是以飞机的噪声距离曲线(NPD 曲线)为核心,用相应的数学模型将其修正至与具体机场的特定环境条件相关的噪声传播模型,存在预测成本高和误差大的缺点.针对这种情况,提出一种使用 BP 神经网络利用机场噪声历史监测数据进行NPD 曲线修正计算方法,从而建立适用于特定机场环境条件的机场噪声预测模型.实验表明,在特定机场的特定环境条件下,允许误差为0.5 dB 时,该模型预测准确率高达91.5%以上,具有预测成本小、准确度高的特点.%Airport noise prediction plays an important role in airport noise controlling, flight planning and airport designing. The airport noise prediction models are usually built based on aircraft noise distance curve(NPD), and the NPD curves are little by little revised to the noise propagation model under the specific airport environmental conditions by using a variety of mathematical models. In this way, there are shortcomings of the high cost and great prediction error. This paper presents an airport noise pre-diction model for particular airport environmental conditions. The proposed model applies BP neural network and history data of the airport noise monitoring to modifying the NPD curves. Experiment results show that in particular specific airport environ-mental conditions, the accuracy rate of noise prediction is more than 91.5% in the case of ±0.5 dB error. The proposed model has the features of lower cost and high accuracy.

    The existing methods to evaluate the airport noise are mainly designed for fixed wing aircraft.In view of the different characters of military helicopter noise,these methods have some shortages and the noise evaluation index can not reflect the whole influence of military helicopter noise on the environment. In order to solve this problem,the characteristics of the military helicopter noise are discussed and the ex-isting index is analyzed.And then a method of multi-index evaluation to evaluate the military helicopter airport noise is proposed by using LAmax and LWCEPN at the same time.This multi-index evaluation method can reflect both total noise level and single burst noise at the same time.The test result shows that this method can reflect the real feeling of the neighbor residents about the noise,which verifies that this multi-index evaluation method is more effective.%现有的机场噪声评价指标主要是针对固定翼飞机设计的,并不能很好地反映军用直升机噪声对机场周围目标的影响。首先分析了军用直升机机场噪声的特殊性,然后研究了现有机场噪声评价指标的内涵和联系,最后采用最大噪声级L Am ax和加权等效连续感觉噪声级L WCEPN联合评价的方法对军用直升机机场噪声进行评价。该联合评价方法可以同时反映总噪声级与单次突发噪声的影响,能较为完备地对军用直升机场噪声进行评价。实测案例表明,此方法能更准确有效反映附近居民对噪声影响的感受。

    In this paper, a case study was conducted in Guangban Airport to research the airport noise adopting the Weighted Equivalent Continuous Perceive Noise Level (LWECPN) recommended by International Civil Aviation Organization (ICAO) as a rating parameter. By means of quantitative analysis using MATLAB, a linear equation was set up to describe the aircraft noise level at monitoring points around the airport versus the logarithms of the distances between the monitoring points and the nmway centerline. Then the linear equation was used to predict the LWECPN of the points else and compared with the data determined. The results showed that the predicted values were close to the measured values with relative error ranging in 1.0% ~ 2.0%. It should be emphasized that this method is easy to operation and it is quick to obtain the results. It provides a new prediction method for noise prediction, having practical significance.%本文以机场飞机噪声为研究对象,采用国际民航组织推荐使用的计权等效连续感觉噪声级(LWECPN)为评价量,以广汉机场为例,通过定量分析,利用MATLAB拟合出机场周围各监测点飞机噪声与跑道中心线对数距离的线性方程,然后将该方程用于对未知监测点的LWECPN预测,并与实测数据对比检验其准确度。结果表明,采用该线性拟合预测方法所得到的未知监测点的噪声预测值与实测值较为接近,两者的相对误差保持在1.0%到2.0%之间,预测准确度较好。值得一提的是,该方法操作相对简便,可以达到快速预测机场周边噪声敏感点LWECPN的目的,为今后飞机噪声的预测研究提出一种新的预测方法,具有一定的实际意义。

    A study has been conducted of the future noise environment of Patric Henry Airport and its neighboring communities projected for the year 1990. An assessment was made of the impact of advanced noise reduction technologies which are currently being considered. These advanced technologies include a two-segment landing approach procedure and aircraft hardware modifications or retrofits which would add sound absorbent material in the nacelles of the engines or which would replace the present two- and three-stage fans with a single-stage fan of larger diameter. Noise Exposure Forecast (NEF) contours were computed for the baseline (nonretrofitted) aircraft for the projected traffic volume and fleet mix for the year 1990. These NEF contours are presented along with contours for a variety of retrofit options. Comparisons of the baseline with the noise reduction options are given in terms of total land area exposed to 30 and 40 NEF levels. Results are also presented of the effects on noise exposure area of the total number of daily operations.

    Acute noise exposure may acutely increase blood pressure but the hypothesis that acute exposure to aircraft noise may trigger cardiovascular events has not been investigated. This study took advantage of a six-day closure of a major airport in April 2010 caused by volcanic ash to examine if there was a decrease in emergency cardiovascular hospital admissions during or immediately after the closure period, using an interrupted daily time-series study design. The population living within the 55dB(A) noise contour was substantial at 0.7 million. The average daily admission count was 13.9 (SD 4.4). After adjustment for covariates, there was no evidence of a decreased risk of hospital admission from cardiovascular disease during the closure period (relative risk 0.97 (95% CI 0.75-1.26)). Using lags of 1-7 days gave similar results. Further studies are needed to investigate if transient aircraft noise exposure can trigger acute cardiovascular events.

Adaboost method was used to airport noise data sampling,and then multiple SVR forecasting models were trained. With the help of a sorting method,forecasting models selec-tive ensemble was achieved and used to predict the final airport noise value,proved has a good prediction effect.

  17. Airport Heterotopia

    DEFF Research Database (Denmark)

    Christiansen, Steen Ledet

    Airports are areas of transit, places of in-between-ness where mobility is key; airports function not just as transfer points where people are moved from one place to another, but also as areas where mobile technology is critically important to make sure that travellers can stay connected....... The airport serves as a node in the network of flows that is air travel. Airports orchestrate social life into distinct movements and behaviors. The ontology of the airport is peculiarly split between a sense of placelessness, while at the same time being a place of material organization and social complexity....... It is a system of interconnected material worlds, and thus a heterotopia; a blending space of overlapping ontologies. Ursula Le Guin playfully examines this concept of overlapping ontologies in her short story collection Changing Planes, where airport travellers can shift realities due to the unpleasantries...

    准确预测机场噪声对控制噪声影响、制定航班计划和规划机场周边环境具有重要意义。而现有机场噪声预测模型复杂,需要监测和采集较多高精度数据作为输入参数,给机场噪声预测增加了困难。针对上述问题该文提出基于动态集成学习的预测模型,该模型基于粗糙集理论对历史监测数据集进行约简分组并构造属性子集,然后对由3维空间向量拟合属性子集生成的基模型进行动态集成。实验结果表明,预测参数完整时,该模型针对特定机型的预测准确性优于现有模型。即使预测参数部分缺失,预测结果也能随参数的增多逐渐逼近真实值。%The prediction of airport noise plays an important role in airport noise control, flight schedule planning and surrounding designs of airport. However, the existing prediction models are complex and need so many highly accurate parameters that are monitored and collected as input of the model, hence adding difficulties to the prediction of airport noise. In order to solve these problems, this paper presents a prediction model based on the rough set and ensemble learning. Accordingly, the attributes of monitored noise data around airport is first reduced by the rough set and the subsets of attributes is produced then, the dynamic ensemble learning is used to combine base learners which are presented in three-dimensional coordinates based on the subsets of attributes. The results of experiments show that the proposed model can predict the noise of specific aircraft with full parameters being more accurately than existing models. And even if there is a lack in part of parameters, the prediction outcome of the model is able to approach the real value of airport noise while gradually increasing parameters.

Based on the data provided by the French Civil Aviation Authority, a weighted average exposure to aircraft noise (L den AEI was computed at the commune level. A Poisson regression model with commune-specific random intercepts, adjusted for potential confounding factors including air pollution, was used to investigate the association between mortality rates and L den AEI. Positive associations were observed between L den AEI and mortality from cardiovascular disease [adjusted mortality rate ratio (MRR per 10 dB(A increase in L den AEI = 1.18; 95% confidence interval (CI: 1.11-1.25], coronary heart disease [MRR = 1.24 (1.12-1.36], and myocardial infarction [MRR = 1.28 (1.11-1.46]. Stroke mortality was more weakly associated with L den AEI [MRR = 1.08 (0.97-1.21]. These significant associations were not attenuated after the adjustment for air pollution. The present ecological study supports the hypothesis of an association between aircraft noise exposure and mortality from cardiovascular disease, coronary heart disease, and myocardial infarction. However, the potential for ecological bias and the possibility that this association could be due to residual confounding cannot be excluded.

    近年来国内民航迅速发展,机场的新建、扩建和航空运输量的持续增长使得机场噪声污染事件不仅持续上升,而且噪声污染程度也日益加重,因而强化机场附近噪声污染的监测对机场建设及其环境评估十分重要。针对机场噪声污染监测问题,提出一种基于非负矩阵分解(NMF)方法对机场噪声监测点布局问题进行优化求解。该方法以大量网格点作为候选监测点,对单个飞机噪声事件候选监测点的噪声值所形成的矩阵按非负矩阵分解进行区域划分,得到噪声影响子区域。进一步以各子区域的中心点作为该区域的噪声影响代表点,以此确定机场噪声监测点数目和位置。研究结果表明所获得的解比贪心算法得到的解更优,需要的监测点更少。%With the rapid development of domestic civil aviation in recent years, noise pollution of airports is becoming a serious problem. Thus, strengthening the noise monitoring in the airport vicinity is very important for airport construction and environmental evaluation. Aiming at the monitoring of airport noise pollution, an optimization method based on non-negative matrix factorization (NMF) is put forward to optimize the layout of the noise monitoring sites. In this method, large number of the grid nodes is employed as the candidate monitoring points, and the non-negative matrix composed of the noise values from single flight event at the candidate monitoring points is formed. Then, the non-negative matrix is factorized to obtain the effective subdivision of noise. Furthermore, the location and number of the noise monitoring sites are determined by the representative central point of the effective subdivisions. It is shown that this method needs fewer monitoring locating sites and can get better results than the greedy algorithm.

    Traditional airport noise prediction models are insufficient for their high modeling cost and poor practicability. In this paper, the time series phase space reconstruction theory is introduced, and a novel integrated airport noise prediction model based on fast extreme learning machine and differential evolution is proposed. In the proposed model, the airport noise time series is reconstructed based on the phase space reconstruction theory, and the fast extreme learning machine is used to model the reconstructed phase space vector. Meanwhile, an improved differential evolution algorithm is adopted to search for the optimal parameter combination of phase space reconstruction parameter and model parameter simultaneously. The whole modeling process of the integrated prediction model is very simple and efficient without any manual intervention. Experimental results demonstrate that the proposed model can track the variation tendency of airport noise well and can achieve much more accurate prediction results than its counterparts.%该文针对传统机场噪声预测模型存在的建模成本高、实用性差的不足,引入时间序列相空间重构理论,提出一种新的基于快速极限学习机和差分进化算法的机场噪声一体化预测模型。该模型利用相空间重构理论对机场噪声时间序列进行重构,并使用快速极限学习机对重构的相空间矢量进行学习建模,同时采用改进的差分进化算法实现对重构参数和模型参数的同步优化选择,整个建模过程简洁高效,无需人工干预。实验结果表明,该一体化预测模型能较好地跟踪机场噪声的变化趋势,且具有较同类模型更小的预测误差。

    2013-01-01

    Many noise-assessment methods for airport are used and their threshold criteria are different from each other. A new method based on land use category was proposed to resolve the difficulty of comparison of these threshold criteria. The land around airport was classified into three categories according to use type. Various major threshold criteria were analyzed, and reunified by land use category. The relationship between threshold criteria and land use category was defined. Comparison of different threshold criteria was accomplished by comparing the area of land. Case study showed the threshold criterion for Weighted Equivalent Continuous Perceived Noise Level (WECPNL) was the most rigorous, followed by Australia Noise Exposure Forecast(ANEF), and Day-Night Average Noise Level(DNL) was the most lenient. To make WECPNL threshold criteria more effective, the minimum of it is suggested to adjust to 74 dB, and the maximum to 80 dB. Results showed the method based on land use category for comparison of different airport-noise-assessment threshold criteria is feasible.%现行的机场噪声评价方法众多,其限值标准各不相同.针对限值标准间难以相互比较这一问题,提出了一种基于土地使用分类的比较方法.将受机场噪声影响的区域按照土地使用类型划分为3类,结合不同评价方法的特点,将限值标准统一到一致的土地使用类型.定义限值区间和土地使用类型的关系,进而通过计算并比较同类型土地所占面积实现不同限值标准的比较.基于某大型繁忙机场的实例得出记权等效连续感觉噪声级(WECPNL)限值标准最严,澳大利亚噪声暴露预报(ANEF)次之,昼夜平均噪声级(DNL)最为宽松.限值标准过严不利于实施,建议将WECPNL限值标准下限调整为74 dB,上限调整为80dB.验证结果表明通过土地使用分类对不同机场噪声评价限值标准进行比较的方法切实可行.

    为监测和分析中小型机场附近噪声污染状况,提出一种基于单个飞机噪声事件最小顶点覆盖模型的机场噪声监测点分布方法.该方法以大量网格点作为候选监测点,形成顶点集合,利用INM噪声预测软件计算各顶点在每个噪声事件发生时的噪声值,根据单个飞机噪声事件的限值确定各项点监测到的噪声事件,从而建立最小顶点覆盖模型,然后采用改进的贪心算法求得近似最优解,使得顶点能覆盖所有噪声事件并且个数最少,实验证明改进的贪心算法比传统的贪心算法得到的解更优,需要的监测点更少.%In order to monitor and analyze the noise pollution around a small and medium scale airport, a locating method of airport noise monitoring points based on minimum vertex cover model of single aircraft noise event was proposed. First of all, a large number of grid points constituting the vertex set were assumed as candidate monitoring points. The INM noise prediction software was used to calculate the noise values of these vertices when each event happened. According to the noise threshold of single event, one could determine whether a vertex monitors the event or not. Then the minimum vertex cover model could be established. After that, the minimum number of vertices which cover all noise events could be obtained by employing the improved greedy algorithm. Experimental results show that the improved greedy algorithm is better than traditional greedy algorithm. It needs less monitoring points for covering all noise events.

    2009-01-01

    Volcanic activity has caused significant hazards to numerous airports worldwide, with local to far-ranging effects on travelers and commerce. Analysis of a new compilation of incidents of airports impacted by volcanic activity from 1944 through 2006 reveals that, at a minimum, 101 airports in 28 countries were affected on 171 occasions by eruptions at 46 volcanoes. Since 1980, five airports per year on average have been affected by volcanic activity, which indicates that volcanic hazards to airports are not rare on a worldwide basis. The main hazard to airports is ashfall, with accumulations of only a few millimeters sufficient to force temporary closures of some airports. A substantial portion of incidents has been caused by ash in airspace in the vicinity of airports, without accumulation of ash on the ground. On a few occasions, airports have been impacted by hazards other than ash (pyroclastic flow, lava flow, gas emission, and phreatic explosion). Several airports have been affected repeatedly by volcanic hazards. Four airports have been affected the most often and likely will continue to be among the most vulnerable owing to continued nearby volcanic activity: Fontanarossa International Airport in Catania, Italy; Ted Stevens Anchorage International Airport in Alaska, USA; Mariscal Sucre International Airport in Quito, Ecuador; and Tokua Airport in Kokopo, Papua New Guinea. The USA has the most airports affected by volcanic activity (17) on the most occasions (33) and hosts the second highest number of volcanoes that have caused the disruptions (5, after Indonesia with 7). One-fifth of the affected airports are within 30 km of the source volcanoes, approximately half are located within 150 km of the source volcanoes, and about three-quarters are within 300 km; nearly one-fifth are located more than 500 km away from the source volcanoes. The volcanoes that have caused the most impacts are Soufriere Hills on the island of Montserrat in the British West Indies

    This report is about the market for airline travel in northern New Mexico. Interest in developing a northern New Mexico regional airport has periodically surfaced for a number of years. The New Mexico State Legislature passed a memorial during the 1998 Second Session calling for the conduct of a study to determine the feasibility of building a new regional airport in NNM. This report is a study of the passenger market feasibility of such an airport. In addition to commercial passenger market feasibility, there are other feasibility issues dealing with siting, environmental impact, noise, economic impact, intermodal transportation integration, region-wide transportation services, airport engineering requirements, and others. These other feasibility issues are not analyzed in any depth in this report although none were discovered to be show-stoppers as a by-product of the authors doing research on the passenger market itself. Preceding the need for a detailed study of these other issues is the determination of the basic market need for an airport with regular commercial airline service in the first place. This report is restricted to an in-depth look at the market for commercial passenger air service in NNM. 20 figs., 8 tabs.

    Full Text Available Increased air transport volumes force carriers to make more frequent flights as well as airport operations. Unfortunately, such progress has some negative effects which the main is environment nuisances. Due to its reach, aircraft noise is one of the most important and unpleasant effects of airport operations. The problem of protecting the environment against noise is becoming increasingly more important on the international market. A lot is being done here by the European Union, which urges or obliges Member States to comply with certain rules, laws and standards aimed at preventing too much interference of socio-economic development with nature 19]. Considering how air transport is growing, it is necessary to conduct studies into airport throughput including throughput environment. This throughput is determined by Restricted Use Area and it is defined as acceptable daily number of performed air operations resulting from the noise limit at airport. There are the following noise level limits classification: noise level limits per flight which is measured at monitoring points, with special attention paid to those measures specific to night-time and noise volume limits over a time-period, particularly at night-time.

    Full Text Available Air traffic density in India and the world at large is growing fast and posing challengingproblems. The problems encountered can be parameterized as flight delay, workload of air trafficcontrollers and noise levels in and around aerodromes. Prediction and quantification of theseparameters aid in developing strategies for efficient air traffic management. In this study, themethod used for quantifying is by simulation and analysis of the selected aerodrome and airspace. This paper presents the results of simulation of HAL Bangalore International Airport,which is used by civil as well as military aircraft. With the test flying of unscheduled militaryaircraft and the increase in the civil air traffic, this airport is hitting the limit of acceptable delay.The workload on air traffic controllers is pushed to high during peak times. The noise contourprediction, especially for the test flying military aircraft is sounding a wake up call to thecommunities living in the vicinity of the Airport.

    Full Text Available In the last twenty years the number of flights at the busiestairports in the world has doubled, which, in the meantime hasled to a situation in which runways and taxi ways (manoeuvringareas cannot follow such substantial increase. As the result,many airports could not use their capacities in the full range interms of handling passengers and cargo. As a consequence,there were delays and traffic congestion, fuel was unnecessarilywasted, all of which caused negative impact on the environment.Traffic capacity increase on the ground cannot be consideredwithout the development and implementation of thesystem infrastructure that would optimize traffic flows and itsdistribution on the airport itself In these terms, and for positivesolution of these problems, a new system for surveillance andcontrol of aircraft on the airport manoeuvring areas is necessary,one which could be implemented fairly quickly, would becomplementary with the existing international standards andwould be upgraded to the existing and available technology andinfrastructure. With the implementation of the Advanced SurfaceMonitoring and Control System (A-SMGCS the aircrafttaxiing time could be significantly shortened and could be determinedmore accurately, which would have positive impacton the flight schedule. The unnecessary aircraft braking actionscould be also avoided, and this would reduce the fuel consumption,as well as noise and environmental pollution.

  16. CYBER SECURITY FOR AIRPORTS

    2013-12-01

    Full Text Available In today’s information age, government organizations and business enterprises are heavily relying on interconnected computer systems to manage a variety of public services including energy, transportation, water, etc. While this increased connectivity has many operational advantages benefitting the public, they have also become vulnerable to cyber attacks such as Corporate Security Breaches, Spear Phishing, and Social Media Fraud. The aviation sector is one the critical infrastructure systems that is not only vulnerable to physical threats, but also cyber threats, especially with the increased use of Bring Your Own Device (BYOD at airports. It has been recognized that there is currently no cyber security standards established for airports in the United States as the existing standards have mainly focused on aircraft Control System (CS. This paper summarizes the need, background, ongoing developments and research efforts with respect to the establishment of cyber-security standards and best practices at U.S. airports with special emphasis on cyber security education and literacy.

  19. Airport Pricing Strategies

    Science.gov (United States)

    Pels, Eric; Verhoef, Erik T.

    2003-01-01

    Conventional economic wisdom suggests that congestion pricing would be an appropriate response to cope with the growing congestion levels currently experienced at many airports. Several characteristics of aviation markets, however, may make naive congestion prices equal to the value of marginal travel delays a non-optimal response. This paper has developed a model of airport pricing that captures a number of these features. The model in particular reflects that airlines typically have market power and are engaged in oligopolistic competition at different sub-markets; that part of external travel delays that aircraft impose are internal to an operator and hence should not be accounted for in congestion tolls. We presented an analytical treatment for a simple bi-nodal symmetric network, which through the use of 'hyper-networks' would be readily applicable to dynamic problems (in discrete time) such as peak - off-peak differences, and some numerical exercises for the same symmetric network, which was only designed to illustrate the possible comparative static impacts of tolling, in addition to marginal equilibrium conditions as could be derived for the general model specification. Some main conclusions are that second-best optimal tolls are typically lower than what would be suggested by congestion costs alone and may even be negative, and that the toll as derived by Brueckner (2002) may not lead to an increase in total welfare. While Brueckner (2002) has made clear that congestion tolls on airports may be smaller than expected when congestion costs among aircraft are internal for a firm, our analysis adds to this that a further downward adjustment may be in order due to market power. The presence of market power (which causes prices to exceed marginal costs) may cause the pure congestion toll to be suboptimal, because the resulting decrease in demand is too high (the pure congestion tall does not take into account the decrease in consumer surplus). The various

  20. The employment and income benefits of airport operation on the country in transition

    Directory of Open Access Journals (Sweden)

    2013-03-01

    Full Text Available Background: The air transport market in Poland is undergoing significant changes, which take place both on the demand and supply side. Polish airports have experienced the unprecedented growth of air traffic. However, the increase in the number of airline connections - which benefits airports, passengers, aircraft industry and, indirectly, the whole society - at the same time results in the growth of social costs reflected by the intensification of noise and environmental pollution. The benefits of airport operation are reflected in the generation of employment and income. Existing literature reveals a gap in the knowledge in respect of impact of aviation in countries in transition. Material and methods: This paper investigates the applicability of socio-economic impact of air transport model to country in transition. In particular, it presents the employment and income benefits of airport operation. The input-output model is employed to measure the economic benefits of airport operation. The largest airport in Poland, Warsaw Chopin Airport is used as a case study. Results: The estimation results for the income and employment effects are found to be significant.  The operations of Warsaw Chopin Airport contributed to the generation of 527.8m EUR in current prices in 2011. Altogether, 19,349 jobs have been generated as the result of the direct, indirect and induced impact of Warsaw Chopin Airport.  Conclusion:  The size of production in the airport expressed in the number of aircraft operations and the number of passengers and goods serviced is positively correlated with the level of economic impact. The restriction on the development of the airport reflected by the inability to meet transport needs expressed by the society may generate opportunity costs.

  11. Airport electric vehicle powered by fuel cell

    Science.gov (United States)

    Fontela, Pablo; Soria, Antonio; Mielgo, Javier; Sierra, José Francisco; de Blas, Juan; Gauchia, Lucia; Martínez, Juan M.

    Nowadays, new technologies and breakthroughs in the field of energy efficiency, alternative fuels and added-value electronics are leading to bigger, more sustainable and green thinking applications. Within the Automotive Industry, there is a clear declaration of commitment with the environment and natural resources. The presence of passenger vehicles of hybrid architecture, public transport powered by cleaner fuels, non-aggressive utility vehicles and an encouraging social awareness, are bringing to light a new scenario where conventional and advanced solutions will be in force. This paper presents the evolution of an airport cargo vehicle from battery-based propulsion to a hybrid power unit based on fuel cell, cutting edge batteries and hydrogen as a fuel. Some years back, IBERIA (Major Airline operating in Spain) decided to initiate the replacement of its diesel fleet for battery ones, aiming at a reduction in terms of contamination and noise in the surrounding environment. Unfortunately, due to extreme operating conditions in airports (ambient temperature, intensive use, dirtiness, …), batteries suffered a very severe degradation, which took its toll in terms of autonomy. This reduction in terms of autonomy together with the long battery recharge time made the intensive use of this fleet impractical in everyday demanding conditions.

[ Methods] The noise intensity was measured in noise exposed workshops, 808 noise exposed workers were tested in terms of the pure tone audibility threshold, and the statistical analysis was carried out to identify the correlation between hearing loss and service length/type of work. [ Results ] There was the largest number of workers who suffered from hearing loss of 4 000 Hz high frequency audibility threshold; The heating loss detected rate rose along with the increase of service length , The hearing loss was significantly different between groups with different service length ( P <0.01). The hearing loss was not significantly different between worker of different type of work ( P > 0.05 ). [ Conclusion ] The noise exposed workers' high frequency audibility threshold is evidently influenced by the noise exposed working conditions. The hearing loss detected rate rises along with the increase of noise exposed length. It is recommended to strengthen self- protection and establish a health monitoring and protection record to avoid hearing loss induced by occupational noise.

    Full Text Available Purpose: Airport Surface Access faces two main opposite issues: (1 cars, being the main transport mode, contribute to the increasing level of congestion and pollution of cities; and (2 simultaneously, parking fees are one important source of airports commercial revenue, creating a dilemma for airports when facing the problem. Following the recent trend of air passengers travelling with Smartphone (78% in 2013, the purpose of this paper is to monitor the adoption of mobile Applications (Apps by airports and to analyze if the information and functions provided in those Apps can help to overcome the above two issues. Design/methodology/approach: 31 iPhone App of some of the largest European airports were evaluated in the lab using the evaluation model of Destinations Mobile Applications (Scolari and Fernández-Cavia 2014 adapted for for the Airport Surface Access on Airport Apps Findings and Originality/value: The Apps evaluated provided a very limited functionality to help passengers to plan and book their trips to/from the airports on public transports and gave high priority to parking information and services. Originality/value: Although Airport Surface Access has been a widely researched, the originality of this paper is the analysis of airport mobile Apps as a potential tool for airports to deal with the surface airport access problems.Access, Airports, Mobile Internet, Commercial Revenues

    Full Text Available Data Envelopment Analysis (DEA has been one of the most important tools on measuring the relative efficiency of different similar units such as transportation systems using terminals, airports, etc. In this study, we perform an empirical analysis on Iranian airports based on DEA methods to measure the efficiencies of various airports. One of the primary issues on many traditional DEA methods is that the data are almost always contaminated with noise. We use a DEA method which could handle the uncertainty associated with input and output data. The results of this comprehensive study show that most of the active airlines are practically inefficient and the government could significantly increase the efficiencies of the airports by setting new regulations and rules.

    2011-01-01

    With the rapid development of economy and the accelerated globalization process, the aviation industry plays more and more critical role in today's world, in both developed and developing countries. As the infrastructure of aviation industry, the airport network is one of the most important indicators of economic growth. In this paper, we investigate the evolution of Chinese airport network (CAN) via complex network theory. It is found that although the topology of CAN remains steady during the past several years, there are many dynamic switchings inside the network, which changes the relative relevance of airports and airlines. Moreover, we investigate the evolution of traffic flow (passengers and cargoes) on CAN. It is found that the traffic keeps growing in an exponential form and it has evident seasonal fluctuations. We also found that cargo traffic and passenger traffic are positively related but the correlations are quite different for different kinds of cities.

    Science.gov (United States)

    Fields, James M.

    1990-01-01

    Most surveys of residents' reactions to aircraft noise were conducted in the vicinity of airports. The findings in those surveys have supported planning and regulatory actions for the airport noise environment. Now, however, aircraft noise planning and regulations are being considered for a new environment, the en route environment. As policy makers search for bases for public policy in these new noise environments, it is appropriate to ask whether the same scientific evidence which supports airport noise policy can also support en route noise policy. Several aspects of that question are considered. An introduction establishes the scope of the present study and examines alternative study methodologies. Next, the selected study methodology is described and important assumptions are listed. The body of the paper then consists of the findings on en route issues. The final section presents findings on relevant research methods and considers priorities for further research.

    Iavicoli, Ivo; Fontana, Luca; Ancona, Carla; Forastiere, Francesco

    2014-01-01

    Airport is an extremely complex emission source of airborne pollutants that can have a significant impact on the environment. Indeed, several airborne chemicals emitted during airport activities may significantly get worse air quality and increase exposure level of both airport workers and general population living nearby the airports. In recent years airport traffic has increased and consequently several studies investigated the association between airport-related air pollution and occurrence of adverse health effects, particularly on respiratory system, in exposed workers and general population resident nearby. In this context, we carried out a critical evaluation of the studies that investigated this correlation in order to obtain a deeper knowledge of this issue and to identify the future research needs. Results show that the evidence of association between airport-related air pollution and health effects on workers and residents is still limited.

    Full Text Available Along with an increase in the aircraft engine power and growth in air traffic, noise level at airports and their surrounding environs significantly increases. Aircraft noise is high level noise spreading within large radius and intensively irritating the human body. Air transport is one of the main sources of noise having a particularly strong negative impact on the environment. The article deals with activities and noises taking place in the largest nationwide Vilnius International Airport.The level of noise and its dispersion was evaluated conducting research on the noise generated by emerging and descending aircrafts in National Vilnius Airport. Investigation was carried out at 2 measuring points located in a residential area. There are different types of aircrafts causing different sound levels. It has been estimated the largest exceedances that occur when an aircraft is approaching. In this case, the noisiest types of aircrafts are B733, B738 and AT72. The sound level varies from 70 to 85 dBA. The quietest aircrafts are RJ1H and F70. When taking off, the equivalent of the maximum sound level value of these aircrafts does not exceed the authorized limits. The paper describes the causes of noise in aircrafts, the sources of origin and the impact of noise on humans and the environment.Article in Lithuanian

  16. SOME ISSUES OF THE AIRPORT MANAGEMENT

    Directory of Open Access Journals (Sweden)

    Marian Ovidiu

    2012-07-01

    Full Text Available Internationally, the recommended standards for the operation and management of civil-use airports are provided by the International Civil Aviation Organization (ICAO. In most individual countries, airports are managed directly by the government, most often under the ministry of transport. In some countries, including EU countries, some airports are privately owned and operated, although, despite private ownership, they are still subject to much of the country’s regulations regarding aviation operations. The complex system of civil airports is made up of individual airport facilities of varying sizes, serving various purposes, all organized into plans of regional, national, and international levels. The range of rules, regulations, and policies, administered from varying levels of government, cover the full spectrum of airport and aviation system operations. Furthermore, a large number of professional and industry organizations play a large part in influencing the policies by which airport management must operate their facilities. By understanding where an airport manager’s airport falls within the civil aviation system, what rules must be followed, and what sources of support and assistance exist, the task of efficiently managing the complex system that is an airport, becomes highly facilitated.

  20. How to assess the compensations for home relocation: the case of the Malpensa airport

    Directory of Open Access Journals (Sweden)

    Alessandra Oppio

    2016-01-01

    Full Text Available The development of the Malpensa airport into a Hub for the Central and South Europe has produced on one side relevant economic impacts, on the other one considerable environmental problems, due to the noise and atmospheric pollution, especially for the inhabitants who live within a distance of 400 meters from the airport.  In the face of this difficult situation, the Lombardy Region has endorsed an agreement for relocating and compensating households affected by the environmental negative externalities. In this context the paper introduces the appraisal procedure used for estimating compensations and discusses the results, mostly in terms of deviation from the expected values and effectiveness of the model.

  15. Siting Solar Photovoltaics at Airports: Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Kandt, A.; Romero, R.

    2014-06-01

    Airports present a significant opportunity for hosting solar technologies due to their open land; based on a 2010 Federal Aviation Administration study, the US Department of Agriculture, and the US Fish and Wildlife Service, there's potential for 116,704 MW of solar photovoltaics (PV) on idle lands at US airports. PV has a low profile and likely low to no impact on flight operations. This paper outlines guidance for implementing solar technologies at airports and airfields, focusing largely on the Federal Aviation Administration's policies. The paper also details best practices for siting solar at airports, provides information on the Solar Glare Hazard Analysis Tool, and highlights a case study example where solar has been installed at an airport.

    Full Text Available A survey of community annoyance induced by aircraft noise exposure was carried out around Hangzhou Xiaoshan International Airport. To investigate the relationship curves between aircraft noise and the percentage of "highly annoyed" persons in China and also to get annoyance threshold of aircraft noise in China. Noise annoyance induced by aircraft noise exposure was assessed by 764 local residents around the airport using the International Commission on Biological Effect of Noise (ICBEN scale. The status quo of aircraft noise pollution was measured by setting up 39 monitoring points. The interpolation was used to estimate the weighted effective continuous perceived noise levels (LWECPN in different areas around the airport, and the graph of equal noise level contour was drawn. The membership function was used to calculate the annoyance threshold of aircraft noise. Data were analyzed using SPSS 16.0 and Origin 8.0. The results showed that if LWECPN was 64.3 dB (Ldn was 51.4 dB, then 15% respondents were highly annoyed. If LWECPN was 68.1 dB (Ldn was 55.0 dB, then 25% respondents were highly annoyed. The annoyance threshold of aircraft noise (LWECPN was 73.7 dB, while the annoyance threshold of a single flight incident instantaneous noise level (LAmax was 72.9 dB. People around the airport had felt annoyed before the aircraft noise LWECPN reached the standard limit.

  8. Environmental noise and human prenatal growth

    Energy Technology Data Exchange (ETDEWEB)

    Schell, L.M.

    1981-09-01

    To determine whether chronic exposure to relatively loud noise has demonstrable biological effects in humans, a study was conducted on the effect of mother's exposure to airport noise while pregnant, and of social and biological characteristics of the family upon birthweight and gestation length. The sample of births was drawn from a community located adjacent to an international airport in the U.S., where noise levels had been measured previously. Mother's noise exposure was based upon noise levels near her residence in the community while she was pregnant. Data from 115 births were used, these being from mothers whose noise exposure history was most complete throughout the pregnancy. Using multivariate analysis to correct for family characteristics, the partial correlation coefficient for noise exposure and gestation length was negative, large, and significant in girls (r . -0.49, p less than 0.001). In boys the partial correlation coefficient was also negative but was smaller and did not quite reach statistical significance. Partial correlations with birthweight were smaller in both boys and girls and not significant. These results agree best with previous studies that suggest that noise may reduce prenatal growth. The size of the observed effects may be related to a conservative research design biased towards underestimation, as well as to the real effects of noise upon human prenatal growth.

  9. The associations between noise sensitivity, reported physical and mental health, perceived environmental quality, and noise annoyance

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available One hundred and ninety residents around Frankfurt Airport (46% female; 17-80 years were interviewed concerning noise annoyance due to transportation noise (aircraft, road traffic, perceived mental and physical health, perceived environmental quality, and noise sensitivity. The aim of the analyses was to test whether noise sensitivity reflects partly general environmental sensitivity and is associated with an elevated susceptibility for the perception of mental and physical health. In this study, the reported physical and mental health variables were not associated with noise exposure but with noise annoyance, and were interpreted to reflect nonspecific codeterminants of annoyance rather than noise effects. Noise sensitivity was found to influence total noise annoyance and aircraft noise annoyance but to a lesser degree annoyance due to road traffic noise. Noise sensitivity was associated with reported physical health, but not with reported mental health. Noise-sensitive persons reported poorer environmental quality in their residential area than less sensitive persons in particular with regard to air traffic (including the facets noise, pollution, and contaminations and quietness. Other aspects of the perceived quality of the environment were scarcely associated with noise sensitivity. This indicates that noise sensitivity is more specific and a reliable predictor of responses to noise from the dominant source (in this case air traffic rather than a predictor of the individual perception of the environmental quality in general.

  13. Airport Gate Assignment: New Model and Implementation

    CERN Document Server

    Li, Chendong

    2008-01-01

    Airport gate assignment is of great importance in airport operations. In this paper, we study the Airport Gate Assignment Problem (AGAP), propose a new model and implement the model with Optimization Programming language (OPL). With the objective to minimize the number of conflicts of any two adjacent aircrafts assigned to the same gate, we build a mathematical model with logical constraints and the binary constraints, which can provide an efficient evaluation criterion for the Airlines to estimate the current gate assignment. To illustrate the feasibility of the model we construct experiments with the data obtained from Continental Airlines, Houston Gorge Bush Intercontinental Airport IAH, which indicate that our model is both energetic and effective. Moreover, we interpret experimental results, which further demonstrate that our proposed model can provide a powerful tool for airline companies to estimate the efficiency of their current work of gate assignment.

    From left to right:Carlo Lamprecht, Luciano Maiani and Jean-Pierre Jobin. When you step off your plane at Geneva Airport there's a good chance you'll come face-to-face with an advertising hoarding bearing the message 'CERN, the world's largest particle physics research laboratory, where the World Wide Web was born...five minutes from here'. This may be obvious to you, but it certainly isn't to the majority of the 7 million travellers who pass through the gates of Geneva Airport every year. On the initiative of the Chairman of its Board of Directors, State Councillor Carlo Lamprecht, Geneva International Airport has therefore come up with the idea of highlighting CERN's presence by giving the Laboratory its own hoarding. The hoarding was inaugurated on 24 May by Carlo Lamprecht, Airport Director Jean-Pierre Jobin and CERN Director-General Luciano Maiani.

  15. Aircraft engine exhaust emissions and other airport-related contributions to ambient air pollution: A review

    Science.gov (United States)

    Masiol, Mauro; Harrison, Roy M.

    2014-10-01

    Civil aviation is fast-growing (about +5% every year), mainly driven by the developing economies and globalisation. Its impact on the environment is heavily debated, particularly in relation to climate forcing attributed to emissions at cruising altitudes and the noise and the deterioration of air quality at ground-level due to airport operations. This latter environmental issue is of particular interest to the scientific community and policymakers, especially in relation to the breach of limit and target values for many air pollutants, mainly nitrogen oxides and particulate matter, near the busiest airports and the resulting consequences for public health. Despite the increased attention given to aircraft emissions at ground-level and air pollution in the vicinity of airports, many research gaps remain. Sources relevant to air quality include not only engine exhaust and non-exhaust emissions from aircraft, but also emissions from the units providing power to the aircraft on the ground, the traffic due to the airport ground service, maintenance work, heating facilities, fugitive vapours from refuelling operations, kitchens and restaurants for passengers and operators, intermodal transportation systems, and road traffic for transporting people and goods in and out to the airport. Many of these sources have received inadequate attention, despite their high potential for impact on air quality. This review aims to summarise the state-of-the-art research on aircraft and airport emissions and attempts to synthesise the results of studies that have addressed this issue. It also aims to describe the key characteristics of pollution, the impacts upon global and local air quality and to address the future potential of research by highlighting research needs.

  17. Energy Research in Airports: A Review

    Directory of Open Access Journals (Sweden)

    Sergio Ortega Alba

    2016-05-01

    Full Text Available The main function of an airport is to provide access to air transport both for passengers and cargo. The number of air operations over the past 20 years has increased rapidly, and this has led to a rise in the energy needs of airports to satisfy this demand. As a consequence, the cost of energy supply for airport managers has escalated. At the same time, global energy consumption has soared due to the needs of emerging countries like China and India, with the consequent environmental impact. This complex scenario of environmental and economic factors has made airport managers become aware of the need to reduce energy consumption as well as a more efficient use of it. The aim of this article is to analyze the main behaviors and energy trends at airports in more recent research, starting with the description of the main energy sources and consumers, the application of energy conservation and energy efficiency measures, the establishment of energy indicators and benchmarking between airports, as well as energy modeling and simulation.

  18. Airport Merchandising Using Micro Services Architecture

    Directory of Open Access Journals (Sweden)

    Hari Bhaskar Sankaranarayanan

    2016-06-01

    Full Text Available Airport offers an ecosystem where passengers, airlines, airport, and merchants meet under one roof during travel. During the journey, there is a good amount of time spent by passengers on waiting or transit before boarding the flight. Passengers look for spending that time by shopping, dining, and entertainment. Airport merchants and airlines look for merchandising opportunities to acquire new customers, up-sell, and cross-sell their products and services. Highly personalized merchandising offers can be generated on the fly by combining contextual information from passenger profile, likes and interests, merchant offers, and location specific events, seasons, and festivals. To achieve this, a strong airport merchandising platform is needed. The goal of the airport merchandising platform is to exchange information in a seamless manner across travel systems. The platform is designed on microservices design principles that use information from airlines, airport, social media, and merchant systems. Microservices can promote quick development, deployment, and realization of services. Microservices also improve the time to market capabilities. Mobile and desktop applications consume them to offer a personalized shopping experience to the passengers.

    2015-09-01

    Full Text Available Airports are a key link of the air transport infrastructure, which is a part of the whole transportation system. Their potential is determined by a network of airlines relations and affects the long-term, strategic position in the market of aviation services. The most possible scenario of the macro-environment of the Gdansk Airport has a relatively high predictability and generally positive influencing on the potential for development in the next years. Only international and demographic areas can constitute a barrier to achieving the strategic objectives. Gdansk Airport takes permanently the third position on the Polish market. Strategic gap analysis leads to the conclusion that, compared to its main competitors Airport Gdansk has a gap of compliance trends, but in relation to smaller regional airports excess gap. GDN services are located in the square "Star" in the BCG matrix. This airport has prepared an investment program till 2035. The dynamics of the projected increase in the number of passengers and air operations in Gdansk is generally slightly higher than the growth nationwide forecasts. The strategic challenge for next years will be to strengthen the status of the GDN as a Polish aviation gateway to Scandinavia.

  20. Aviation Impacts on Property Values and Management: The Case of Suvarnabhumi International Airport

    Directory of Open Access Journals (Sweden)

    Patcharin Limlomwongse Suksmith

    2015-07-01

    Full Text Available Many countries have developed policies and measures to deal with the external impact of aviation on the wider community. There is, however, often controversy and lack of acceptance of some measures, such as compensation, in the communities affected by aviation. Such measures are often felt to be ineffective and perceived as unfair. A clear and objective model for determining compensation would be helpful to reduce controversy. The objective of this study is therefore to examine the relationship between aviation impacts and property values in the case of Thailand's Suvarnabhumi Airport for application to the possible improvement of compensation packages. Multiple regression analysis was used to determine the relationship between five common impacts of aviation (safety, noise, scenery, air pollution, and traffic and property value change, with data from a survey of sample communities around the airport. The results, both for the overall neighborhood and for separate land used types, show that only noise and air pollution demonstrate significant negative relations with property value. The effect of noise drives a higher impact on property price than the effect of air pollution. The main contribution of this research is to improve developing country compensation models by applied measurement from regression analysis to identify factors with significant impacts, using property value change as proxy to measure the impact of the airport. For example, in the case of Thailand, a compensation model should consider noise and air pollution as the main factors rather than consider only noise contour area. The higher weight on noise should be designed to reflect land use types. Furthermore the market value of property loss should be taken into account when designing a compensation package. The survey and regression method used in this study can be adapted for finding relevant factors and suggesting appropriate compensation for other environmental and

  2. Sampling for global epidemic models and the topology of an international airport network.

    Directory of Open Access Journals (Sweden)

    Georgiy Bobashev

    Full Text Available Mathematical models that describe the global spread of infectious diseases such as influenza, severe acute respiratory syndrome (SARS, and tuberculosis (TB often consider a sample of international airports as a network supporting disease spread. However, there is no consensus on how many cities should be selected or on how to select those cities. Using airport flight data that commercial airlines reported to the Official Airline Guide (OAG in 2000, we have examined the network characteristics of network samples obtained under different selection rules. In addition, we have examined different size samples based on largest flight volume and largest metropolitan populations. We have shown that although the bias in network characteristics increases with the reduction of the sample size, a relatively small number of areas that includes the largest airports, the largest cities, the most-connected cities, and the most central cities is enough to describe the dynamics of the global spread of influenza. The analysis suggests that a relatively small number of cities (around 200 or 300 out of almost 3000 can capture enough network information to adequately describe the global spread of a disease such as influenza. Weak traffic flows between small airports can contribute to noise and mask other means of spread such as the ground transportation.

    The scope of this project was changed during the course of the project. Phase I of the project was designed to have the National Alternative Fuels Training Consortium (NAFTC), together with its partners, manage the Hydrogen Vehicle Test Project at the Yeager Airport in conjunction with the Central West Virginia Regional Airport Authority (CWVRAA) in coordination with the United States Department of Energy National Energy Technology Laboratory (U.S. DOE NETL). This program would allow testing and evaluation of the use of hydrogen vehicles in the state of West Virginia utilizing the hydrogen fueling station at Yeager Airport. The NAFTC and CWVRAA to raise awareness and foster a greater understanding of hydrogen fuel and hydrogen-powered vehicles through a targeted utilization and outreach and education effort. After initial implementation of the project, the project added, determine the source(s) of supply for hydrogen powered vehicles that could be used for the testing. After completion of this, testing was begun at Yeager Airport. During the course of the project, the station at Yeager Airport was closed and moved to Morgantown and the West Virginia University Research Corporation. The vehicles were then moved to Morgantown and a vehicle owned by the CWVRAA was purchased to complete the project at the new location. Because of a number of issues detailed in the report for DE-FE0002994 and in this report, this project did not get to evaluate the effectiveness of the vehicles as planned.

  5. Location of airports - selected quantitative methods

    2016-09-01

    Full Text Available Background: The role of air transport in  the economic development of a country and its regions cannot be overestimated. The decision concerning an airport's location must be in line with the expectations of all the stakeholders involved. This article deals with the issues related to the choice of  sites where airports should be located. Methods: Two main quantitative approaches related to the issue of airport location are presented in this article, i.e. the question of optimizing such a choice and the issue of selecting the location from a predefined set. The former involves mathematical programming and formulating the problem as an optimization task, the latter, however, involves ranking the possible variations. Due to various methodological backgrounds, the authors present the advantages and disadvantages of both approaches and point to the one which currently has its own practical application. Results: Based on real-life examples, the authors present a multi-stage procedure, which renders it possible to solve the problem of airport location. Conclusions: Based on the overview of literature of the subject, the authors point to three types of approach to the issue of airport location which could enable further development of currently applied methods.

    2003-11-01

    To prevent SARS from spreading through air travel and in order to rebuild the confidence of the traveling public in the safety of air travel, ICAO has set up an "Anti-SARS Airport Evaluation Project." The first phase of this project was to develop a set of protective measures for international airports in affected areas to adopt and implement and then to send out, on the request of Contracting States, a team of inspectors to evaluate and assess airports and issue a "statement of evaluation" that the airport inspected complies with the ICAO anti-SARS protective measures. In cooperation with the World Health Organization (WHO), the first part of phase 1 was completed in early June this year, and the second part of phase 1 followed soon after. By mid-July, five international airports in Southeast Asia had been inspected and found to be in full compliance with the ICAO anti-SARS protective measures. The success of this ICAO project is believed to have contributed significantly to the recovery of international air travel and related industries now taking place. Phase 2 of the project is now being developed. It is aimed at preventing a resurgence of SARS, but it also contains elements to make the methodology developed applicable to future outbreaks of any other communicable disease in which the mode of transmission could involve aviation and/or the need to prevent the spread of the disease by air travel.

    Full Text Available The paper attempts to characterize changes occurring in EU transport policy, taking into account innovation of airports and aerodromes. To face challenges like: increase in air traffic, ensuring safety of flight operations, regional development or requirements of passengers it is necessary to determine desired direction network of airports and aerodromes within the aviation policy, which is part of the national and European transport policy. Overview of national and EU studies, strategies and legislative plans enable to specify changes taking place in the EU aviation policy, as well as to create potential scenarios of its development with particular attention to the innovation of aerodromes and airports. Based on the above analysis it should be noted, that aims of the European institutions and agencies are: reduction amount of restrictive rules on general aviation (including GA aerodromes, spread concepts of multimodality and Small Aircraft Transport Systems, enhance competitiveness of the EU aviation sector but also reduction investment funding at airports. Conclusions may be a theoretical inspiration in the process of updating master plans of aerodromes and airports.

    This circumstance leads to considerable mistakes it creation of SPZ borders of the airports, in some cases it impedes development of the latters and causes objective difficulties for hygienic assessment of projects. In this article the results of studies on the creation and validation of two new domestic methods for the construction of impact zones of aircraft noise and dispersion of the concentrations of pollutants in assessing the negative impact of airports are considered. Both branch methods agreed upon with the Ministry of Transport have been harmonized with ICAO (International Civil Aviation Organization) requirements. The results of full-scale measurements have confirmed the possibilities of developed software for their implementation in the formation of a common SPZ border of an airport.

    Full Text Available Air transportation industry is a globally growing industry. As an inseparable part of this industry, airport management is also becoming more crucial issue to be dealt with. Airports offer economic and social benefits to the society, but also environmental impacts of airport operations are increasing due to high traffic growth. While airport capacity is increasing, airport operators are being responsible for mitigating environmental constraints. Today to implement airport environmental management system is seen as a critical way of solution. To ensure effective implementation of this system, an organizational change with definite roles, responsibilities and structure are needed. This study illustrates a way of organizational response to market forces and national regulations guiding the achievement of sustainable airports by determining the structure and the roles in an airport organization.

  15. Productivity Analysis of Public and Private Airports: A Causal Investigation

    Science.gov (United States)

    Vasigh, Bijan; Gorjidooz, Javad

    2007-01-01

    Around the world, airports are being viewed as enterprises, rather than public services, which are expected to be managed efficiently and provide passengers with courteous customer services. Governments are, increasingly, turning to the private sectors for their efficiency in managing the operation, financing, and development, as well as providing security for airports. Operational and financial performance evaluation has become increasingly important to airport operators due to recent trends in airport privatization. Assessing performance allows the airport operators to plan for human resources and capital investment as efficiently as possible. Productivity measurements may be used as comparisons and guidelines in strategic planning, in the internal analysis of operational efficiency and effectiveness, and in assessing the competitive position of an airport in transportation industry. The primary purpose of this paper is to investigate the operational and financial efficiencies of 22 major airports in the United States and Europe. These airports are divided into three groups based on private ownership (7 British Airport Authority airports), public ownership (8 major United States airports), and a mix of private and public ownership (7 major European Union airports. The detail ownership structures of these airports are presented in Appendix A. Total factor productivity (TFP) model was utilized to measure airport performance in terms of financial and operational efficiencies and to develop a benchmarking tool to identify the areas of strength and weakness. A regression model was then employed to measure the relationship between TFP and ownership structure. Finally a Granger causality test was performed to determine whether ownership structure is a Granger cause of TFP. The results of the analysis presented in this paper demonstrate that there is not a significant relationship between airport TFP and ownership structure. Airport productivity and efficiency is

    Full Text Available In response to global energy problems (e.g., the oil crisis, the Fukushima accident, the Paris Agreement, the South Korean government has executed a strict renewable energy plan to decrease the country’s dependence on fossil fuel. Public facilities, such as international airports, which use substantial amounts of electricity, are the most in need of government regulation. In this study, we attempt to determine the optimal hybrid electricity generation system for South Korea’s largest airport: Incheon International Airport. In the analysis, we use three scenarios: the current load, 120% of the current load, and 140% of the current load, according to the plan to expand Incheon International Airport. According to the COE (cost of electricity and the NPC (net present cost of the result, it is economically feasible to completely cover the potential increase in the electric load with PV power. Government policy implications and limitations are discussed.

    2014-01-01

    Full Text Available Airport gate assignment is core task for airport ground operations. Due to the fact that the departure and arrival time of flights may be influenced by many random factors, the airport gate assignment scheme may encounter gate conflict and many other problems. This paper aims at finding a robust solution for airport gate assignment problem. A mixed integer model is proposed to formulate the problem, and colony algorithm is designed to solve this model. Simulation result shows that, in consideration of robustness, the ability of antidisturbance for airport gate assignment scheme has much improved.

  4. Fluctuations in airport arrival and departure traffic: A network analysis

    Institute of Scientific and Technical Information of China (English)

    Li Shan-Mei; Xu Xiao-Hao; Meng Ling-Hang

    2012-01-01

    Air traffic is a typical complex system,in which movements of traffic components (pilots,controllers,equipment,and environment),especially airport arrival and departure traffic,form complicated spatial and temporal dynamics.The fluctuations of airport arrival and departure traffic are studied from the point of view of networks as the special correlation between different airports.Our collected flow volume data on the time-dependent activity of US airport arrival and departure traffic indicate that the coupling between the average flux and the fluctuation of an individual airport obeys a certain scaling law with a wide variety of scaling exponents between 1/2 and 1.These scaling phenomena can explain the interaction between the airport internal dynamics (e.g.queuing at airports,a ground delay program and following flying traffic) and a change in the external (network-wide) traffic demand (e.g.an increase in traffic during peak hours every day),allowing us to further understand the mechanisms governing the collective behaviour of the transportation system.We separate internal dynamics from external fluctuations using a scaling law which is helpful for us to systematically determine the origin of fluctuations in airport arrival and departure traffic,uncovering the collective dynamics.Hot spot features are observed in airport traffic data as the dynamical inhomogeneity in the fluxes of individual airports.The intrinsic characteristics of airport arrival and departure traffic under severe weather is discussed as well.

  8. Effects of Changed Aircraft Noise Exposure on the Use of Outdoor Recreational Areas

    Directory of Open Access Journals (Sweden)

    Norun Hjertager Krog

    2010-11-01

    Full Text Available This paper examines behavioural responses to changes in aircraft noise exposure in local outdoor recreational areas near airports. Results from a panel study conducted in conjunction with the relocation of Norway’s main airport in 1998 are presented. One recreational area was studied at each airport site. The samples (n = 1,264/1,370 were telephone interviewed about their use of the area before and after the change. Results indicate that changed aircraft noise exposure may influence individual choices to use local outdoor recreational areas, suggesting that careful considerations are needed in the planning of air routes over local outdoor recreational areas. However, considerable stability in use, and also fluctuations in use unrelated to the changes in noise conditions were found. Future studies of noise impacts should examine a broader set of coping mechanisms, like intra- and temporal displacement. Also, the role of place attachment, and the substitutability of local areas should be studied.

    Full Text Available Noise is a public health problem and, more than that, a source of discomfort perceived strongly by population. World Health Organization (WHO has undertaken studies that have underlined the harmful aspects of noise on the human body, and EU regulations have aligned their requirements to both WHO standards and the standards set by International Civil Aviation Organization (ICAO. At national level, Romania has adopted rules on controlling noise, which transposed the European directives in the field. This study presents the legal measures taken by France to mitigate noise pollution around airports, of which the act establishing compensations for residents for soundproofing homes would be a good example for Romania.

  12. Characterization and Analysis of Energy Demand Patterns in Airports

    Directory of Open Access Journals (Sweden)

    Sergio Ortega Alba

    2017-01-01

    Full Text Available Airports in general have high-energy consumption. Influenced by many factors, the characteristics of airport energy consumption are stochastic, nonlinear and dynamic. In recent years, airport managers have made huge efforts to harmonize airport operation with environmental sustainability by minimizing the environmental impact, with energy conservation and energy efficiency as one of their pillars. A key factor in order to reduce energy consumption at airports is to understand the energy use and consumption behavior, due to the multiple parameters and singularities that are involved. In this article, a 3-step methodology based on monitoring methods is proposed to characterize and analyze energy demand patterns in airports through their electric load profiles, and is applied to the Seve Ballesteros-Santander Airport (Santander, Spain. This methodology can be also used in airports in order to determine the way energy is used, to establish the classification of the electrical charges based on their operation way as well as to determine the main energy consumers and main external influencers. Results show that airport present a daily energy demand pattern since electric load profiles follow a similar curve shape for every day of the year, having a great dependence of the terminal building behavior, the main energy consumer of the airport, and with heating, ventilation and air conditioning (HVAC and lighting being the most energy-intensive facilities, and outside temperature and daylighting the main external influencers.

  16. RISK ASSESSMENT PROCEDURE FOR CIVIL AIRPORT

    Directory of Open Access Journals (Sweden)

    Natalia Distefano

    2014-03-01

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

    1998-08-01

    At the direction of the US Congress, following the Pan Am 103 and TWA 800 crashes, the Federal Aviation Administration funded development of non-invasive techniques to screen airline passengers for explosives. Such an explosives detection portal, developed at Sandia National Laboratories, was field tested at the Albuquerque International airport in September 1997. During the 2-week field trial, 2,400 passengers were screened and 500 surveyed. Throughput, reliability, maintenance and sensitivity were studied. Follow-up testing at Sandia and at Idaho National Engineering and Environmental Laboratory was conducted. A passenger stands in the portal for five seconds while overhead fans blow air over his body. Any explosive vapors or dislodged particles are collected in vents at the feet. Explosives are removed from the air in a preconcentrator and subsequently directed into an ion mobility spectrometer for detection. Throughput measured 300 passengers per hour. The non-invasive portal can detect subfingerprint levels of explosives residue on clothing. A survey of 500 passengers showed a 97% approval rating, with 99% stating that such portals, if effective, should be installed in airports to improve security. Results of the airport test, as well as operational issues, are discussed.

  3. Environmental impacts on soil and groundwater at airports: origin, contaminants of concern and environmental risks.

    Science.gov (United States)

    Nunes, L M; Zhu, Y-G; Stigter, T Y; Monteiro, J P; Teixeira, M R

    2011-11-01

    Environmental impacts of airports are similar to those of many industries, though their operations expand over a very large area. Most international impact assessment studies and environmental management programmes have been giving less focus on the impacts to soil and groundwater than desirable. This may be the result of the large attention given to air and noise pollution, relegating other environmental descriptors to a second role, even when the first are comparatively less relevant. One reason that contributes to such "biased" evaluation is the lack of systematic information about impacts to soil and groundwater from airport activities, something the present study intends to help correct. Results presented here include the review of over seven hundred documents and online databases, with the objective of obtaining the following information to support environmental studies: (i) which operations are responsible for chemical releases?; (ii) where are these releases located?; (iii) which contaminants of concern are released?; (iv) what are the associated environmental risks? Results showed that the main impacts occur as a result of fuel storage, stormwater runoff and drainage systems, fuel hydrant systems, fuel transport and refuelling, atmospheric deposition, rescue and fire fighting training areas, winter operations, electrical substations, storage of chemical products by airport owners or tenants, and maintenance of green areas. A new method for ranking environmental risks of organic substances, based on chemical properties, is proposed and applied. Results show that the contaminants with the highest risks are the perfluorochemicals, benzene, trichloroethylene and CCl(4). The obtained information provides a basis for establishing the planning and checking phases of environmental management systems, and may also help in the best design of pollution prevention measures in order to avoid or reduce significant environmental impacts from airports.

    Richard Ramaroson1,4, Klaus Schaefer2, Stefan Emeis2, Carsten Jahn2, Gregor Schürmann2, Maria Hoffmann2, Mikhael Zatevakhin3, Alexandre Ignatyev3. 1ONERA, Châtillon, France; 4SEAS, Harvard University, Cambridge, USA; 2FZK, Garmisch, Germany; (3)FSUE SPbAEP, St Petersburg, Russia. 2-month field campaigns have been organized at CDG airports in autumn 2004 and summer 2005. Air quality and ground air traffic emissions have been monitored continuously at terminals and taxi-runways, along with meteorological parameters onboard trucks and with a SODAR. This paper analyses the commercial engine emissions characteristics at airports and their effects on gas pollutants and airborne particles coupled to meteorology. LES model results for PM dispersion coupled to microphysics in the PBL are compared to measurements. Winds and temperature at the surface and their vertical profiles have been stored with turbulence. SODAR observations show the time-development of the mixing layer depth and turbulent mixing in summer up to 800m. Active low level jets and their regional extent have been observed and analyzed. PM number and mass size distribution, morphology and chemical contents are investigated. Formation of new ultra fine volatile (UFV) particles in the ambient plume downstream of running engines is observed. Soot particles are mostly observed at significant level at high power thrusts at take-off (TO) and on touch-down whereas at lower thrusts at taxi and aprons ultra the UFV PM emissions become higher. Ambient airborne PM1/2.5 is closely correlated to air traffic volume and shows a maximum beside runways. PM number distribution at airports is composed mainly by volatile UF PM abundant at apron. Ambient PM mass in autumn is higher than in summer. The expected differences between TO and taxi emissions are confirmed for NO, NO2, speciated VOC and CO. NO/NO2 emissions are larger at runways due to higher power. Reactive VOC and CO are more produced at low powers during idling at

  7. A Geometric Fuzzy-Based Approach for Airport Clustering

    Directory of Open Access Journals (Sweden)

    Maria Nadia Postorino

    2014-01-01

    Full Text Available Airport classification is a common need in the air transport field due to several purposes—such as resource allocation, identification of crucial nodes, and real-time identification of substitute nodes—which also depend on the involved actors’ expectations. In this paper a fuzzy-based procedure has been proposed to cluster airports by using a fuzzy geometric point of view according to the concept of unit-hypercube. By representing each airport as a point in the given reference metric space, the geometric distance among airports—which corresponds to a measure of similarity—has in fact an intrinsic fuzzy nature due to the airport specific characteristics. The proposed procedure has been applied to a test case concerning the Italian airport network and the obtained results are in line with expectations.

  10. Sleep disturbance due to noise: Current issues and future research

    Directory of Open Access Journals (Sweden)

    Ken Hume

    2010-01-01

    Full Text Available There is growing interest in carrying out further research to understand and reduce the impact of aircraft noise on airport neighborhood in anticipation of the projected substantial increase in global aviation. Soundscapes provide new analytical methods and a broader, more comprehensive appreciation of the aural environment, which may have a useful role in understanding noise-induced sleep disturbance and annoyance. Current noise metrics like Leq do not provide a common language to report noise environment to residents, which is a key obstacle to effective noise management and acceptance. Non-auditory effects complicate the production of consistent dose-response functions for aircraft noise affecting sleep and annoyance. There are various end-points that can be chosen to assess the degree of sleep disturbance, which has detracted from the clarity of results that has been communicated to wider audiences. The World Health Organization (WHO-Europe has produced Night Noise Guidelines for Europe, which act as a clear guide for airports and planners to work towards. Methodological inadequacies and the need for simpler techniques to record sleep will be considered with the exciting potential to greatly increase cost-effective field data acquisition, which is needed for large scale epidemiological studies

  11. Flight Schedule Recovery under Uncertain Airport Capacity

    2016-01-01

    Airlines adj ust their flight schedules to satisfy more stringent airport capacity constraints caused by in-clement weather or other unexpected disruptions.The problem will be more important and complicated if uncertain disruptions occur in hub airports.A two-stage stochastic programming model was established to deal with the real-time flight schedule recovery and passenger re-accommodation problem.The first-stage model represents the flight re-timing and re-fleeting decision in current time period when capacity information is deterministic,while the sec-ond-stage recourse model evaluates the passenger delay given the first-stage solutions when one future scenario is realized.Aiming at the large size of the problem and requirement for quick response,an algorithmic framework combining the sample average approximation and heuristic method was proposed.The computational results indi-cated of that the proposed method could obtain solutions with around 5% optimal gaps,and the computing time was linearly positive to the sample size.

    Science.gov (United States)

    Lucas, Michael J.; Lee, Robert A.

    Whenever there is a reallocation of DOD fixed- or rotary-wing aircraft or a change in the use of the airspace requirements, either an Environmental Assessment or an Environmental Impact Statement must be prepared. These environmental studies require an analysis of the noise impacts resulting from aircraft operations surrounding the airports and under Military Training Routes (MTR's), Military Operating Areas (MOA's), and Ranges. NOISEMAP and ROUTEMAP were developed for the purpose of estimating the noise levels around military airports and under MTR's. Neither of these programs is suitable for estimating noise levels under MOA's or Ranges. MR NMAP is a PC-based computer model that has been developed to calculate the noise levels under MOA's and ranges. The program calculates L(sub dn), CNEL, L(sub eq), SEL, L(sub max), and where appropriate L(sub dnmr). The program output is a tabular form or in graphics suitable for inclusion in reports. The computer program is designed for use by environmental planning personnel who are familiar with MOA and range operations and with noise, but are not necessarily expert. The program will be widely distributed to DOD planners and contractors that have a requirement to make noise estimates. A companion graphical user interface (GUI) computer program called MR OPS has been developed that allows the user to draw the airspace, specify areas of high/medium/low activity, and draw the specific flight tracks for bombing runs and military training routes. MR OPS writes an ASCII file that is read by MR NMAP. Contained in this ASCII file is the operation data and keywords that control the computational features in MR NMAP. MR NMAP is written in FORTRAN; executable versions are available under DOS, Windows, and Windows NT. MR OPS is written in the C programming language and will run under Windows and Windows NT.

    The competition among airlines or among airports aiming at to increase the demand for its services has been more and more incited. Knowledge the perception of the users for the offered services means to meet the customer's needs and expectations in order either to keep the customer, and therefore keep a significant advantage over competitors. The passenger of the air transportation wants rapidity, security and convenience. Convenience can be translated by comfort that the passenger wants for the price that he can pay. In this paper had been identified. as a result of a survey achieved in six Brazilian airports during 2002, the best indicators in the passenger's perception. These indicators among any others were listed m the handbook of Airports Council International (ACI). Distinctive perceptions were observed among passengers with different travel motivations. This survey had been carried through in the airports of Brasilia, Porto Alegre, Salvador. Fortaleza, Curitiba and Bel6m. Considering this survey we can identified the most attractive airport among them. This work is a way to help improve quality of service, in particular, m these six airports of the Brazilian network. The results should be published and made available to all the parties concerned (airport authority, airlines and service providers) and should lead to corrective action when the passenger is not satisfied with the service.

    2012-03-01

    Scaling up for alternative energy such as solar, wind, and biofuel raises a number of environmental issues, notably changes in land use and adverse effects on wildlife. Airports offer one of the few land uses where reductions in wildlife abundance and habitat quality are necessary and socially acceptable, due to risk of wildlife collisions with aircraft. There are several uncertainties and limitations to establishing alternative energy production at airports, such as ensuring these facilities do not create wildlife attractants or other hazards. However, with careful planning, locating alternative energy projects at airports could help mitigate many of the challenges currently facing policy makers, developers, and conservationists.

  8. Characterization of aircraft noise during thrust reverser engagement

    Science.gov (United States)

    Gutierrez, Remy M.; Atchley, Anthony A.; Hodgdon, Kathleen K.

    2005-09-01

    Airport noise impact on communities has been an area of considerable study. However, it has been determined that thrust reverser engagement is an area requiring further research. This paper presents findings on thrust reverser from a noise study done at Washington-Dulles International Airport (IAD) in October of 2004. Previous studies have found that high levels of acoustic energy in commercial aircraft during takeoff are contained below 300 Hz [Sharp, Ben H., Guovich, Yuri A., and Albee, William, W., ``Status of Low-Frequency Aircraft Noise Research and Mitigation,'' Wyle Report WR 01-21, San Francisco, September 2001]. Preliminary analysis of thrust reverser signatures indicates similar findings. A categorization of aircraft noise during thrust reverser engagement is given and looks at factors that may affect the noise characteristics. Some of these factors include: plane type, engine type, and thrust ratings. In addition, a brief analysis of frequency weightings of the Equivalent Sound Level (Leq) and Sound Exposure Level (SEL) metrics, and their application to thrust reverser noise is discussed.

    Full Text Available Noise in the workplace has traditionally been linked to both auditory and non-auditory disorders in people exposed. Recently the noise around airports has been linked to di erent pathologies, primarily cardiovascular-related. In recent years, environmental noise in large cities, due, to a large extent, to tra c, has been linked to various cardiovascular and respiratory diseases, and even to diabetes. In this article, in addition to giving a brief description of studies linking ambient noise and morbidity and of the di erent biological mechanisms involved that may explain these associations, we present the results of a series of studies which link by means of time-series analysis link tra c noise in the city of Madrid and daily mortality for cardiovascular, respiratory and diabetes-related reasons in the group of 65+ year-olds, as well as the annual mortality attributable to tra c noise in Madrid and its comparison with that attributable to PM2.5.

  13. The economic impact of South Africa’s international airports

    Full Text Available Infrastructure is strongly linked to economic growth and plays a major role in providing greater mobility and choice, leading to an improvement in incomes and welfare. Transport infrastructure such as highways, bridges, ports, airports and railways is critical in achieving economic growth. If the supply of these facilities does not keep up with rising demand, the cost of moving goods will increase, and there will be a downward pressure on profits and growth. Airports play a critical role in generating employment within an economy, creating wealth, contributing to the tax base, stimulating tourism and contributing to world trade. While the latter two are less easily measured, it is possible to determine a base impact that an airport has on an economy by measuring the direct and indirect gross domestic product, employment and taxation impacts. This study quantifies these for the three main international airports in South Africa.

    Air traffic is increasing, raising concern about local pollution and its adverse health effects on the people living in the vicinity of large airports. However, the highest risk is probably occupational exposure due to proximity. Jet exhaust is one of the main concerns at an airport and may have a health impact, particularly on the respiratory tract. Current studies are neither numerous enough nor strong enough to prove this kind of association. Yet, more and more people work in airports, and occupational exposure to jet exhaust is a fact. The aim of this review was to evaluate the existing knowledge regarding the impact of airport pollution on respiratory health.

    Full Text Available It is imperative for airport operators and airlines to have a clear understanding of the factors which influence the passenger’s decision with regard to which airport/airline combination to use in a multi-airport scenario. Interactions between demographic variables, such as gender and purpose of travel, and the choice attributes in the decision-making process exist. The extent to which specific attributes influence the passenger’s decision could be invaluable to service providers (airport operators and airlines in allocating and employing limited resources. The purpose of this article is to investigate the extent of the interactions between passenger demographics and attribute evaluation by taking into account the ordinal nature of the measurement scale.

    Full Text Available Purpose: The main objective of this paper is to determine the annual cyclical flight delays at Hartsfield-Jackson Atlanta International Airport. Then using other data such as annual precipitation, passenger and aircraft traffic volumes and other factors, we attempted to correlate these factors with overall delays. These data could assist airport management in predicting periods of flight delay.Design/methodology/approach: Data were taken and analyzed from the data base “Research and Innovation Technology Administration” (RITA for the years 2005-2011 for Hartsfield-Jackson Atlanta International Airport. The data included 2.8 million flights originating and departing from this airport. Data were also gathered from the National Oceanic and Atmospheric Administration (NOAA showing precipitation. Additional data were gathered from the FAA regarding delay causes, number and types of delays and changes to the infrastructure of ATL airportFindings: There is a repeatable annual pattern of delays at ATL that can be modeled using delay data from the Bureau of Transportation Statistics. This pattern appears to be caused primarily by the frequency and amount of precipitation that falls at ATL and by the amount of flights that arrive and depart at ATL.Originality/value: This information could assist airport operations personnel, FAA air traffic controllers and airlines in anticipating and mitigating delays at specific times of the year.

  12. An Algorithm for Managing Aircraft Movement on an Airport Surface

    Directory of Open Access Journals (Sweden)

    Giuseppe Maresca

    2013-08-01

    Full Text Available The present paper focuses on the development of an algorithm for safely and optimally managing the routing of aircraft on an airport surface in future airport operations. This tool is intended to support air traffic controllers’ decision-making in selecting the paths of all aircraft and the engine startup approval time for departing ones. Optimal routes are sought for minimizing the time both arriving and departing aircraft spend on an airport surface with engines on, with benefits in terms of safety, efficiency and costs. The proposed algorithm first computes a standalone, shortest path solution from runway to apron or vice versa, depending on the aircraft being inbound or outbound, respectively. For taking into account the constraints due to other traffic on an airport surface, this solution is amended by a conflict detection and resolution task that attempts to reduce and possibly nullify the number of conflicts generated in the first phase. An example application on a simple Italian airport exemplifies how the algorithm can be applied to true-world applications. Emphasis is given on how to model an airport surface as a weighted and directed graph with non-negative weights, as required for the input to the algorithm.

Besides, the monitoring points and monitoring range is not cleared in the new standard. Many factors restrict the monitoring data effectively and timely, such as doubled monitoring time, the 1 class of monitoring instruments, more strict requirements for the effective statistical monitoring data. So if there is no standard noise monitoring technology supporting this new standard, we will encounter great technical obstacles in the implementation process.%《机场周围区域飞机噪声环境标准》征求意见稿),将原来的“计权等效连续感觉噪声级(LWECPN)”,而改为“昼夜等效声级(Ldn)”,又不同于声环境质量功能区的Ldn ,监测点位及监测范围未明确;监测时间成倍增加,监测仪器要求为1级,监测有效数据统计要求更严格。由于这些因素都会制约监测数据的及时有效性,如果没有与新标准配套的噪声监测技术规范,新标准实施过程中会遇到很大技术障碍。

    2003-01-01

    By entraining large quantities of ambient air into advanced ejector nozzles, the jet noise of the proposed High Speed Civil Transport (HSCT) is expected to be reduced to levels acceptable for airport-vicinity noise certification. Away from the airport, however, this entrained air is shut off and the engines are powered up from their cutback levels to provide better thrust for the climb to cruise altitude. Unsuppressed jet noise levels propagating to the ground far from the airport are expected to be high. Complicating this problem is the HSCT's relative noise level with respect to the subsonic commercial fleet of 2010, which is expected to be much quieter than it is today after the retirement of older, louder, domestic stage II aircraft by the year 2000. In this study, the classic energy state approximation theory is extended to calculate trajectories that minimize the climb to cruise noise of the HSCT. The optimizer dynamically chooses the optimal altitude velocity trajectory, the engine power setting, and whether the ejector should be stowed or deployed with respect to practical aircraft climb constraints and noise limits.

    Human exposure to ultrafine particles (UFP) has been postulated to be associated with adverse health effects, and there is interest regarding possible measures to reduce primary emissions. One important source of UFP are airport activities, with aircraft take-offs being the most relevant one. We implemented two measurement campaigns of total particle number concentrations (PNC), a proxy for UFP, near a medium-size airport in central Italy. One-minute PNC averages were collected on June 2011 and January 2012 concurrently with 30-min average meteorological data on temperature and wind speed/direction. Data on minute-specific take-offs and landings were obtained by the airport authorities. We applied statistical regression models to relate PNC data to the presence of aircraft activities while adjusting for time trends and meteorology, and estimated the increases in PNC ±15 min before and after take-offs and landings. We repeated the analyses considering prevalent wind direction and by size of the aircraft. We estimated PNC increases of 5400 particles/cm3/minute during the 15 min before and after take-offs, with a peak of 19,000 particles/cm3/minute within 5 min after take-offs. Corresponding figures for landings were 1300 and 1000 particles, respectively. The highest PNC estimates were obtained when the prevailing wind came from the runway direction, and led to estimated PNC increases of 60,000 particles/cm3/minute within 5 min after take-offs. No main differences were noted from the exhaust of different types of aircrafts. The area surrounding Ciampino airport is densely inhabited, raising concerns about the potential adverse effects of long-term and short-term exposure to airport-borne UFP. A close monitoring of airport activities and emissions is mandatory to reduce the public health impact of the airport on the nearby population.

    1981-01-01

    The results of solar system performance studies carried out on the final construction of a passive space heating system for the Gunnison County Airport Terminal are presented. The principal topic discussed is the economic performance of the system with supporting material on thermal performance and system design. The conclusions of this study, using the methods of computer modeling and life-cycle economics are: (1) the final design passive solar heating system with night insulation will provide, on the average, 41% of the annual heating load for the terminal, (2) the passive system will result in a saving of 154 million Btu per year or, equivalently, 45,122 kWh per year, and (3) over a 40-year period the system is expected to save 3.1 million dollars in heating energy costs after the solar system investment has been paid off. Over the first 20-year period the net savings are approximately $100,000. The simple payback period is 13 years.

  2. Night time aircraft noise exposure and children′s cognitive performance

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Chronic aircraft noise exposure in children is associated with impairment of reading and long-term memory. Most studies have not differentiated between day or nighttime noise exposure. It has been hypothesized that sleep disturbance might mediate the association of aircraft noise exposure and cognitive impairment in children. This study involves secondary analysis of data from the Munich Study and the UK Road Traffic and Aircraft Noise Exposure and Children′s Cognition and Health (RANCH Study sample to test this. In the Munich study, 330 children were assessed on cognitive measures in three measurement waves a year apart, before and after the switchover of airports. Self-reports of sleep quality were analyzed across airports, aircraft noise exposure and measurement wave to test whether changes in nighttime noise exposure had any effect on reported sleep quality, and whether this showed the same pattern as for changes in cognitive performance. For the UK sample of the RANCH study, night noise contour information was linked to the children′s home and related to sleep disturbance and cognitive performance. In the Munich study, analysis of sleep quality questions showed no consistent interactions between airport, noise, and measurement wave, suggesting that poor sleep quality does not mediate the association between noise exposure and cognition. Daytime and nighttime aircraft noise exposure was highly correlated in the RANCH study. Although night noise exposure was significantly associated with impaired reading and recognition memory, once home night noise exposure was centered on daytime school noise exposure, night noise had no additional effect to daytime noise exposure. These analyses took advantage of secondary data available from two studies of aircraft noise and cognition. They were not initially designed to examine sleep disturbance and cognition, and thus, there are methodological limitations which make it less than ideal in giving

    This work reviewed existing literature on airport related activities that could worsen surrounding air quality; its aim is to underline the progress coming from recent-year studies, the knowledge emerging from new approaches, the development of semi-empiric analytical methods as well as the questions still needing to be clarified. To estimate pollution levels, spatial and temporal variability, and the sources relative contributions integrated assessment, using both fixed point measurement and model outputs, are needed. The general picture emerging from the studies was a non-negligible and highly spatially variable (within 2-3 km from the fence line) airport contribution; even if it is often not dominant compared to other concomitant pollution sources. Results were highly airport-specific. Traffic volumes, landscape and meteorology were the key variables that drove the impacts. Results were thus hardly exportable to other contexts. Airport related pollutant sources were found to be characterized by unusual emission patterns (particularly ultrafine particles, black carbon and nitrogen oxides during take-off); high time-resolution measurements allow to depict the rapidly changing take-off effect on air quality that could not be adequately observed otherwise. Few studies used high time resolution data in a successful way as statistical models inputs to estimate the aircraft take-off contribution to the observed average levels. These findings should not be neglected when exposure of people living near airports is to be assessed.

  4. Z Specification of Gate and Apron Control Management at Airport

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Modelling of an air traffic control (ATC system is an open issue and has become a challenging problem due to its complexity and increase of traffic at airports and in airspace. Consequently, automated ATC systems are suggested to improve efficiency ensuring the safety standards. It is reported that the number of collisions that occurred at airports surface is three times larger than in airspace. Further, it is observed that gates and aprons congestions cause significant delays at airports; hence, effective monitoring and guidance mechanisms are required to control ground air traffic. In this paper, formal procedure of managing air traffic from gate to enter in the active area of airport for taxiing is provided using Z notation. An integration of gate and apron controllers is described to manipulate the information for correct decision making and flow management. Graph theory is used for representation of airport topology and appropriate routs. In static part of the model, safety properties are described in terms of invariants over the critical data types. In dynamic model, the state space is updated by defining pre- and postconditions ensuring the safety. Formal specification is analysed using Z/Eves tool.

    Moreno, Marcelo Baena; Muller, Carlos

    2003-01-01

    Using the conditional LOGIT model, this paper addresses the airport choice in the Sao Paulo Metropolitan Area. In this region, Guarulhos International Airport (GRU) and Congonhas Airport (CGH) compete for passengers flying to several domestic destinations. The airport choice is believed to be a result of the tradeoff passengers perform considering airport access characteristics, airline level of service characteristics and passenger experience with the analyzed airports. It was found that access time to the airports better explain the airport choice than access distance, whereas direct flight frequencies gives better explanation to the airport choice than the indirect (connections and stops) and total (direct plus indirect) flight frequencies. Out of 15 tested variables, passenger experience with the analyzed airports was the variable that best explained the airport choice in the region. Model specifications considering 1, 2 or 3 variables were tested. The model specification most adjusted to the observed data considered access time, direct flight frequencies in the travel period (morning or afternoon peak) and passenger experience with the analyzed airports. The influence of these variables was therefore analyzed across market segments according to departure airport and flight duration criteria. The choice of GRU (located neighboring Sao Paulo city) is not well explained by the rationality of access time economy and the increase of the supply of direct flight frequencies, while the choice of CGH (located inside Sao Paulo city) is. Access time was found to be more important to passengers flying shorter distances while direct flight frequencies in the travel period were more significant to those flying longer distances.

    Full Text Available The method of generating the SAR raw data of complex airport scenes is studied in this paper. A formulation of the SAR raw signal model of airport scenes is given. Via generating the echoes from the background, aircrafts and buildings, respectively, the SAR raw data of the unified SAR imaging geometry is obtained from their vector additions. The multipath scattering and the shadowing between the background and different ground covers of standing airplanes and buildings are analyzed. Based on the scattering characteristics, coupling scattering models and SAR raw data models of different targets are given, respectively. A procedure is given to generate the SAR raw data of airport scenes. The SAR images from the simulated raw data demonstrate the validity of the proposed method.

  9. A Novel Surveillance System Applied in Civil Airport

    Directory of Open Access Journals (Sweden)

    Sun Hua Bo

    2016-01-01

    Full Text Available Conventional security monitoring of civil airport usually uses a fixed camera to acquire images. There are several problems with performance including difficulties introduced in the information transmission, storage, and analysis of the process. Insect compound eyes offer unique advantages for moving target capture and these have attracted the attention of many researchers in recent years. This paper contributes to this research by proposing a new surveillance system applied in civil airport. We discuss the finished bionic structure of the system, the development of the bionic control circuit, and introduce the proposed mathematical model of bionic compound eyes for data acquisition and image mosaic. Image matching for large view is also illustrated with different conditions. This mode and algorithm effectively achieve safety surveillance of airport with large field of view and high real-time processing.

    Airport operations are significantly impacted by low visibility concerned with fog. Generation of accurate and timely nowcast products is a basis of early warning automated system providing information about significant weather conditions for decision-makers. Nowcasting system MeteoExpert has been developed that provides aviation forecasters with 0-6 hour nowcasts of the weather conditions including fog and low visibility. The system has been put into operation at the airport Irkutsk since August 2014. Aim is to increase an accuracy of fog forecasts, contributing to the airport safety, efficiency and capacity improvement. Designed for operational use numerical model of atmospheric boundary layer runs with a 10-minute update cycle. An important component of the system is the use of AWOS at the airdrome and three additional automatic weather stations at fogging sites in the vicinity of the airdrome. Nowcasts are visualized on a screen of forecaster's workstation and dedicated website. Nowcasts have been verified against actual observations.

  16. Vulnerability analysis for airport networks based on fuzzy soft sets: From the structural and functional perspective

    Directory of Open Access Journals (Sweden)

    Li Shanmei

    2015-06-01

    Full Text Available Recently, much attention has been paid to the reliability and vulnerability of critical infrastructure. In air traffic systems, the vulnerability analysis for airport networks can be used to guide air traffic administrations in their prioritization of the maintenance and repair of airports, as well as to avoid unnecessary disturbances in the planning of flight schedules. In this paper, the evaluation methods of airport importance and network efficiency are established. Firstly, the evaluation indices of airport importance are proposed from both the topological and functional perspectives. The topological characteristics come from the structure of airport network and the functional features stem from the traffic flow distribution taking place inside the network. Secondly, an integrated evaluation method based on fuzzy soft set theory is proposed to identify the key airports, which can fuse together importance indices over different time intervals. Thirdly, an airport network efficiency method is established for the purpose of assessing the accuracy of the evaluation method. Finally, empirical studies using real traffic data of US and China’s airport networks show that the evaluation method proposed in this paper is the most accurate. The vulnerability of US and China’s airport networks is compared. The similarities and differences between airport geography distribution and airport importance distribution are discussed here and the dynamics of airport importance is studied as well.

  11. Smoking restrictions in large-hub airports --- United States, 2002 and 2010.

    Science.gov (United States)

    2010-11-19

    Secondhand smoke (SHS) exposure causes death and disease in both nonsmoking adults and children, including cancer, cardiovascular and respiratory diseases. SHS exposure causes an estimated 46,000 heart disease deaths and 3,400 lung cancer deaths among U.S. nonsmoking adults annually. Adopting policies that completely eliminate smoking in all indoor areas is the only effective way to eliminate involuntary SHS exposure. In 2009, an estimated 696 million aircraft passenger boardings occurred in the United States. A 2002 survey of airport smoking policies found that 42% of 31 large-hub U.S. airports had policies requiring all indoor areas to be smoke-free. To update that finding, CDC analyzed the smoking policies of airports categorized as large-hub in 2010. This report summarizes the results of that analysis, which found that, although 22 (76%) of the 29 large-hub airports surveyed were smoke-free indoors, seven airports permitted smoking in certain indoor locations, including three of the five busiest airports. Although a majority of airports reported having specifically designated smoking areas outdoors in 2010 (79%) and/or prohibiting smoking within a minimum distance of entryways (69%), no airport completely prohibited smoking on all airport property. Smoke-free policies at the state, local, or airport authority level are needed for all airports to protect air travelers and workers at airports from SHS.

    Transportation infrastructure plays a vital role in the development of a country’s economy and is regarded as one of the most important indicators of its economic growth. In this study, we analyse the Airport Network of Pakistan (ANP), which represents Pakistan’s domestic civil aviation infrastructure, as a weighted complex network. We find that ANP is a small-world network and is disassortative in nature. We further analyse the dynamic properties of the network and compare them to their topological counterparts. Although small in size, the ANP does show similar properties as compared to the US, China and especially the Indian airport network.

    2010-01-01

    Full Text Available In this paper, an attempt is made to establish the direction of causality between a range of psychological factors and aircraft noise annoyance. For this purpose, a panel model was estimated within a structural equation modeling approach. Data were gathered from two surveys conducted in April 2006 and April 2008, respectively, among the same residents living within the 45 Level day-evening-night contour of Amsterdam Airport Schiphol, the largest airport in the Netherlands (n=250. A surprising result is that none of the paths from the psychological factors to aircraft noise annoyance were found to be significant. Yet 2 effects were significant the other way around: (1 from ′aircraft noise annoyance′ to ′concern about the negative health effects of noise′ and (2 from ′aircraft noise annoyance′ to ′belief that noise can be prevented.′ Hence aircraft noise annoyance measured at time 1 contained information that can effectively explain changes in these 2 variables at time 2, while controlling for their previous values. Secondary results show that (1 aircraft noise annoyance is very stable through time and (2 that changes in aircraft noise annoyance and the identified psychological factors are correlated.

    In this paper, a new method is proposed for airport recognition in complex environments. The algorithm takes all advantages of essential characteristics of the airport target. Structural characteristics of the airport are used to establish assumption process. Improved Hough transformation (HT) is used to check out those right straight-lines which stand for actual position and direction of runways. Morphological processing is used to remove road segments and isolated points. Finally, we combine these segments carefully to describe the whole airport area, and then our automatic recognition of airport target is realized.

  6. NASA's Aeroacoustic Tools and Methods for Analysis of Aircraft Noise

    Science.gov (United States)

    Rizzi, Stephen A.; Lopes, Leonard V.; Burley, Casey L.

    2015-01-01

    Aircraft community noise is a significant concern due to continued growth in air traffic, increasingly stringent environmental goals, and operational limitations imposed by airport authorities. The ability to quantify aircraft noise at the source and ultimately at observers is required to develop low noise aircraft designs and flight procedures. Predicting noise at the source, accounting for scattering and propagation through the atmosphere to the observer, and assessing the perception and impact on a community requires physics-based aeroacoustics tools. Along with the analyses for aero-performance, weights and fuel burn, these tools can provide the acoustic component for aircraft MDAO (Multidisciplinary Design Analysis and Optimization). Over the last decade significant progress has been made in advancing the aeroacoustic tools such that acoustic analyses can now be performed during the design process. One major and enabling advance has been the development of the system noise framework known as Aircraft NOise Prediction Program2 (ANOPP2). ANOPP2 is NASA's aeroacoustic toolset and is designed to facilitate the combination of acoustic approaches of varying fidelity for the analysis of noise from conventional and unconventional aircraft. The toolset includes a framework that integrates noise prediction and propagation methods into a unified system for use within general aircraft analysis software. This includes acoustic analyses, signal processing and interfaces that allow for the assessment of perception of noise on a community. ANOPP2's capability to incorporate medium fidelity shielding predictions and wind tunnel experiments into a design environment is presented. An assessment of noise from a conventional and Hybrid Wing Body (HWB) aircraft using medium fidelity scattering methods combined with noise measurements from a model-scale HWB recently placed in NASA's 14x22 wind tunnel are presented. The results are in the form of community noise metrics and

    This work is a first look at acoustic data acquired in the NASA Glenn Research Center Aero-Acoustic Propulsion Laboratory using the Price Induction DGEN380 small turbofan engine, with particular emphasis on broadband combustor (core) noise. Combustor noise is detected by using a two-signal source separation technique employing one engine-internal sensor and one semi-far-field microphone. Combustor noise is an important core-noise component and is likely to become a more prominent contributor to overall airport community noise due to turbofan design trends, expected aircraft configuration changes, and advances in fan-noise-mitigation techniques.

    Full Text Available Ambient noise harms a number of citizens in Europe. The major sources of environmental noise are that generated by cars in streets, parking lots, railway lines and airports as well as noise from local sources (fans, transformers. According to the methodology for noise measurement, engine testing has been carried out. The conducted analysis has been focused on engine capacity and the distance between vehicles and equipment. Equivalent, maximum and minimum sound levels at different frequencies have been measured accepting that errors may range up to 2 %. Maximum sound level has been reached using the engine of 2000 cm3 petrol capacity. At a half-meter distance, the equivalent sound level reaches 89 dB(A, whereas the noise level decreases moving away from the car. The obtained results of tested cars disclose that according to engine capacity, the majority of the investigated cars are technically faulty and therefore significantly exceed noise levels.Article in Lithuanian

  1. A New Method for Automatically Labeling Aircrafts in Airport Video

    2015-01-01

    Full Text Available For the problem that the airport video monitoring could only provide the image information while the label information including the flight number is not provided, a new method for automatically labeling aircrafts in airport video through the fusion of video and ADS-B data has been proposed. First, the image coordinates of aircrafts will be obtained through the image tracking of video. Then, the homography matrix between two projection planes will be calculated with the four and above point and line correspondences selected from the airport map and video image, respectively to the map image coordinates into the map coordinates. Finally, the aircrafts in video can be automatically labeled through the fusion of image tracking data and ADS-B monitoring data. Because an image coordinate measurement error exists at the time of selecting points from the image, the resulting coordinate conversion error is derived and the impact of point correspondence geometric layout on mesh coordinate mapping error is analyzed. Experiments have been conducted based on the actual data of Chengdu Shuangliu International Airport. The results show that the method can automatically label aircrafts in video in an effective way.

During this period a total of 71 raptors of 9 species were observed, including one breeding species – the Eurasian Marsh Harrier (Circus aeruginosus. The seasonal population dynamics and species composition of Birds of Prey on the territory of the airport was studied. The highest population density and species number occurred during end of June – July, in September and in April. The summer population peak was caused by regular observations of hunting birds, whose nests were located on the territory of the airport and in the close vicinity. Young birds also made a contribution to this peak. Autumn and spring population peaks were caused by more frequent observations of migrating raptors during the seasonal migrations. The lowest number of raptors in the airport was observed in winter.

    2016-10-01

    The results of air quality monitoring carried out over several years (2008-2012) in two international airports near Rome (labelled as A and B) are reported and discussed. Airport A serves regular flights, airport B operates low-cost flights and, during the period investigated, had about 17% of airport A aircraft traffic load. Diffusive sampling of gaseous species (NO2, SO2, BTX and O3) was performed at several sites inside the airports. During 2012 the investigation was improved by including PM10 and polycyclic aromatic hydrocarbons (PAHs). Higher concentrations of NO2 (+18%) and lower of SO2 (-20%) were found at airport B, compared to A, over the whole period investigated. The maximum concentrations of SO2 were measured in 2011 at both airports (13.4 μg/m3 and 10.8 μg/m3 respectively for A and B), despite the decrease of aircraft traffic load recorded. Statistical analysis of PM10 data showed that there was no significant difference between the average concentrations measured at the two airports (25.7 μg/m3 and 27.4 μg/m3 for A and B respectively) and among the sites investigated. The concentration of PAHs at airport B (4.3 ng/m3) was almost twice that of airport A (2.2 ng/m3), though the respective percentages of compounds were similar. Airport B seemed to be negatively influenced by its surroundings, in particular by vehicular traffic flows of two major roads, whereas airport A was positively influenced by the proximity to the seaside. PCA data analysis showed that airport A sites are differently impacted by the LTO flight phases according to their position, whereas at airport B it was impossible to find similar relationships.

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available Cortical neurons in vivo may operate in high-conductance states, in which the major part of the neuron's input conductance is due to synaptic activity, sometimes several-fold larger than the resting conductance. We examine here the contribution of inhibition in such high-conductance states. At the level of the absolute conductance values, several studies have shown that cortical neurons in vivo are characterized by strong inhibitory conductances. However, conductances are balanced and spiking activity is mostly determined by fluctuations, but not much is known about excitatory and inhibitory contributions to these fluctuations. Models and dynamic-clamp experiments show that, during high-conductance states, spikes are mainly determined by fluctuations of inhibition, or by inhibitory noise. This stands in contrast to low-conductance states, in which excitatory conductances determine spiking activity. To determine these contributions from experimental data, maximum likelihood methods can be designed and applied to intracellular recordings in vivo. Such methods indicate that action potentials are indeed mostly correlated with inhibitory fluctuations in awake animals. These results argue for a determinant role for inhibitory fluctuations in evoking spikes, and do not support feed-forward modes of processing, for which opposite patterns are predicted.

    Full Text Available As issued in the Competition Policy Brief on the new state aid rules for a competitive aviation industry by the Competition Directorate-General of the European Commission in February 20141, it will be more difficult for unprofitable airports, to obtain financial public subsidies on EU, national or regional level. Although the positive impact of small airports on the regional development and general accessibility was mentioned, still the operating aid to the airports shall be cut out over a maximum of 10 years. It has been further stated that the vast majority of small and regional airports experience problems to cover their running operative costs, as a result from an intensive market competition and overlapping of airports’ catchment areas preventing even some promising airports from growth. Public subsidies are mostly used by the airport management for infrastructural investments, to cover operating losses or to attract price-sensitive airlines. Herewith, among other things, the EU Commission is pointing out at the lack of cooperation structures and network strategies among the regional airports and at rather isolated and individual approach during elaboration of the airport development scenarios. However, the Competition Policy Brief permits public aid to regional airports, among other things if there is sufficient transports need to establish transition periods for small airports; the need for more flexibility of the regional airports in the remote areas has been underlined. The EU Commission is expecting herewith not to close the regional airports, but to stimulate them to operate on cost efficient and profitable basis, and that only the most inefficient airports will be closed.

    Occupational noise is a frequently encountered on-the-job health hazard. This guide presented the responsibilities and regulatory requirements related to business activities where noise above 80 decibels is present. The guide provided a definition of noise and discussed noise hazards, types of noise, and on-the-job noise exposure. A risk assessment to noise in the work environment was also discussed. A guide to a hearing conservation program was also included. The main purpose of a hearing conservation program is the prevention of noise induced hearing loss for employees exposed to occupational noise. The components of such a program were outlined, with particular reference to noise monitoring; noise exposure control; worker education and training; hearing (audiometric) testing; and annual program review and record keeping. It was concluded that in terms of record keeping, it can be very helpful to file noise exposure assessments, particularly personal exposure measurements, with hearing test records to facilitate for future reference. refs., appendices.

    2011-03-01

    The first phase of noise mapping and action planning in Ireland, in accordance with EU Directive 2002/49/EC, is now complete. In total this included one agglomeration, one airport and approximately 600 km of major roads outside the agglomeration. These noise maps describe the level of noise exposure of approximately 1.25 million people. The first phase of noise mapping was dealt with by five noise mapping bodies while 26 action planning authorities were involved in the development of the associated action plans. The second phase of noise mapping, due to be completed in 2012, sees a reduction in the defined thresholds describing the required agglomerations, roads and railways that have to be mapped. This will have a significant impact on the extent of mapping required. In Ireland this will result in an increased number of local authorities being required to develop strategic noise maps for their area along with the further development of associated action plans. It is appropriate at this point to review the work process and results from the first phase of noise mapping in Ireland in order to establish areas that could be improved, throughout the noise mapping project. In this paper a review of the implementation procedures focussing on (dominant) road traffic noise is presented. It is identified that more standardisation is needed and this could be achieved by the establishment of a national expert steering group.

    Results are presented of numerical experiments modeling meteorology, multiple pollutant sources, and nonlinear photochemical reactions for the case of an airport in a large urban area with complex terrain. A planetary boundary-layer model which predicts the mixing depth and generates wind, moisture, and temperature fields was used; it utilizes only surface and synoptic boundary conditions as input data. A version of the Hecht-Seinfeld-Dodge chemical kinetics model is integrated with a new, rapid numerical technique; both the San Francisco Bay Area Air Quality Management District source inventory and the San Jose Airport aircraft inventory are utilized. The air quality model results are presented in contour plots; the combined results illustrate that the highly nonlinear interactions which are present require that the chemistry and meteorology be considered simultaneously to make a valid assessment of the effects of individual sources on regional air quality.

    Full Text Available There is a lack of studies assessing the exposure-response relationship between transportation noise and annoyance in North America. Our aims were to investigate the prevalence of noise annoyance induced by road traffic, trains and airplanes in relation to distance to transportation noise sources, and to total environmental noise levels in Montreal, Canada; annoyance was assessed as noise-induced disturbance. A telephone-based survey among 4336 persons aged >18 years was conducted. Exposure to total environmental noise (A-weighted outdoor noise levels—LAeq24h and day-evening-night equivalent noise levels—Lden for each study participant was determined using a statistical noise model (land use regression—LUR that is based on actual outdoor noise measurements. The proportion of the population annoyed by road traffic, airplane and train noise was 20.1%, 13.0% and 6.1%, respectively. As the distance to major roads, railways and the Montreal International Airport increased, the percentage of people disturbed and highly disturbed due to the corresponding traffic noise significantly decreased. When applying the statistical noise model we found a relationship between noise levels and disturbance from road traffic and total environmental noise, with Prevalence Proportion Ratios (PPR for highly disturbed people of 1.10 (95% CI: 1.07–1.13 and 1.04 (1.02–1.06 per 1 dB(A Lden, respectively. Our study provides the first comprehensive information on the relationship between transportation noise levels and disturbance in a Canadian city. LUR models are still in development and further studies on transportation noise induced annoyance are consequently needed, especially for sources other than road traffic.

  6. Minimum Climb to Cruise Noise Trajectories Modeled for the High Speed Civil Transport

    Berton, Jeffrey J.

    1998-01-01

    The proposed U.S. High Speed Civil Transport (HSCT) will revolutionize commercial air travel by providing economical supersonic passenger service to destinations worldwide. Unlike the high-bypass turbofan engines that propel today's subsonic airliners, HSCT engines will have much higher jet exhaust speeds. Jet noise, caused by the turbulent mixing of high-speed exhaust with the surrounding air, poses a significant challenge for HSCT engine designers. To resolve this challenge, engineers have designed advanced mixer rejector nozzles that reduce HSCT jet noise to airport noise certification levels by entraining and mixing large quantities of ambient air with the engines' jet streams. Although this works well during the first several minutes of flight, far away from the airport, as the HSCT gains speed and climbs, poor ejector inlet recovery and ejector ram drag contribute to poor thrust, making it advantageous to turn off the ejector. Doing so prematurely, however, can cause unacceptable noise levels to propagate to the ground, even when the aircraft is many miles from the airport. This situation lends itself ideally to optimization, where the aircraft trajectory, throttle setting, and ejector setting can be varied (subject to practical aircraft constraints) to minimize the noise propagated to the ground. A method was developed at the NASA Lewis Research Center that employs a variation of the classic energy state approximation: a trajectory analysis technique historically used to minimize climb time or fuel burned in many aircraft problems. To minimize the noise on the ground at any given throttle setting, high aircraft altitudes are desirable; but the HSCT may either climb quickly to high altitudes using a high, noisy throttle setting or climb more slowly at a lower, quieter throttle setting. An optimizer has been programmed into NASA's existing aircraft and noise analysis codes to balance these options by dynamically choosing the best altitude-velocity path and

  10. Calculation of odour emissions from aircraft engines at Copenhagen Airport.

    Science.gov (United States)

    Winther, Morten; Kousgaard, Uffe; Oxbøl, Arne

    2006-07-31

    In a new approach the odour emissions from aircraft engines at Copenhagen Airport are calculated using actual fuel flow and emission measurements (one main engine and one APU: Auxiliary Power Unit), odour panel results, engine specific data and aircraft operational data for seven busy days. The calculation principle assumes a linear relation between odour and HC emissions. Using a digitalisation of the aircraft movements in the airport area, the results are depicted on grid maps, clearly reflecting aircraft operational statistics as single flights or total activity during a whole day. The results clearly reflect the short-term temporal fluctuations of the emissions of odour (and exhaust gases). Aircraft operating at low engine thrust (taxiing, queuing and landing) have a total odour emission share of almost 98%, whereas the shares for the take off/climb out phases (2%) and APU usage (0.5%) are only marginal. In most hours of the day, the largest odour emissions occur, when the total amount of fuel burned during idle is high. However, significantly higher HC emissions for one specific engine cause considerable amounts of odour emissions during limited time periods. The experimentally derived odour emission factor of 57 OU/mg HC is within the range of 23 and 110 OU/mg HC used in other airport odour studies. The distribution of odour emission results between aircraft operational phases also correspond very well with the results for these other studies. The present study uses measurement data for a representative engine. However, the uncertainties become large when the experimental data is used to estimate the odour emissions for all aircraft engines. More experimental data is needed to increase inventory accuracy, and in terms of completeness it is recommended to make odour emission estimates also for engine start and the fuelling of aircraft at Copenhagen Airport in the future.

    2005-01-01

    A joint flight experiment is conducted by China Aviation Establishment and German Aerospace Center on an Aerospatiale AS350B2 helicopter to investigate rotorcraft flight acoustics at Pingfang airport, Harbing City, China. This paper briefly introduces the methodologies and facilities used in the flight tests. The flight exposure noise levels for ten test flight conditions are showed in the paper and harmonic spectrum and wavelet analysis methods are used for the noise test data processing, which are measured in the flight test in taking off, climbing, forward and descent flight conditions. Results show that the flight noise levels are relatively higher in the climbing and descending flight conditions. The flight noise comes mainly from the tail rotor for the climbing and from the main rotor due to the blade vortex interaction (BVI) for the descending flight conditions. The highest noise level occurs in the forward rotating blade side when the helicopter flys at moderate speed with about 6° descending slide angle.

  15. Noise analysis for near field 3-D FM-CW radar imaging systems

    2015-06-19

    Near field radar imaging systems are used for several applications including concealed weapon detection in airports and other high-security venues. Despite the near-field operation, phase noise and thermal noise can limit the performance in several ways including reduction in system sensitivity and reduction of image dynamic range. In this paper, the effects of thermal noise, phase noise, and processing gain are analyzed in the context of a near field 3-D FM-CW imaging radar as might be used for concealed weapon detection. In addition to traditional frequency domain analysis, a time-domain simulation is employed to graphically demonstrate the effect of these noise sources on a fast-chirping FM-CW system.

    2013-01-01

    Complex networks provide a suitable framework to model air traffic. Previous works described the world air-traffic network as a graph with direct flights between airports as edges and passenger commercial airports as vertices. In this work we study the US airport network, in the time period 2005-2011. We characterize the topological structure of the network and identify how the plane rotations adjust to it. The reactionary delays are supposed to propagate following the structure of this network. We analyze the properties of flight delays including the total distribution of delays, the delays per day of the week and the hour-by-hour evolution of the delays within each day. We pay special attention to the long-delayed flights, those accumulating delays longer than 12 hours, and study when and where this type of incidences is most common. The goal of this work is to gain a better understanding of the factors contributing to the reactionary delay propagation with the aim of developing models able to realistically...

  17. A New Intelligent Airplane Landing Planning Method in Congested Airports

    Full Text Available Nowadays considering many advantages of air traveling, we notice that traffic congestion has significantly increased in airspace of countries, and it is expected that this growth rate, increases even more in the forthcoming years.This growth rate and different limitations posed on developing some airports led to the problem of landing airplanes to become one of the most important issues formed in the field of aviation. In this paper, in the form of a new approach based on CPSO algorithm for intelligent landing planning, determining optimal landing times, optimal allocation of runways, and at last the order of successive landings of planes has been done in a way that appropriately fulfills the main goal of the problem (minimizing the total flights delays; thus helping significantly to controlling air traffic congestion in airports approaches. The simulation results show that compared to the last presented methods, including methods based on genetic algorithms, GLS and Bionomic, has decreased the total amounts of flight delays considerably. Getting zero for total amount of flight delays for the two problems with real data of DFW airport in Texas, United States, confirms the more capability of CPSO algorithm compared to the other intelligent methods for obtaining optimal solutions to the problem.

    Full Text Available The literature indicates that sound and visual stimuli interact in the impression of landscapes. This paper examines the relationship between annoyance with sound from aircraft and annoyance with other area problems (e.g., careless bicycle riding, crowding, etc., and how changes in noise exposure influence the perceived overall recreational quality of outdoor recreational areas. A panel study (telephone interviews conducted before and after the relocation of Norway’s main airport in 1998 examined effects of decreased or increased noise exposure in nearby recreational areas (n = 591/455. Sound from aircraft annoyed the largest proportion of recreationists, except near the old airport after the change. The decrease in annoyance with sound from aircraft was accompanied by significant decreases in annoyance with most of the other area problems. Near the new airport annoyance with most factors beside sound from aircraft increased slightly, but not significantly. A relationship between aircraft noise annoyance and perceived overall recreational quality of the areas was found.

The two other cases were inhabitants of a city at 7 km. Entomological investigations suggest that cars of airport employees served to disseminate anophelines outside the airport areas. The six cases were very severe. One patient died. Apparently, W.H.O. recommendations on aircraft disinsecting procedures have not been fully followed. There is obviously a threat for areas near the airports.

  2. Airport operator and aircraft operator in case of bird strike. Relations, obligations and liability

    Sylwia KACZYŃSKA-ADAMCZYK

    2011-01-01

    Full Text Available Air transport is subject to various risks. One of them is bird strike hazard. Despite numerous regulations concerning prevention from this type of occurrence, it is not possible to eliminate them entirely.Bird strikes most often take place during take-off and landing, that is on or in the vicinity of an airport. For that reason airport operators are the first parties that can be made accountable for this occurence. International law imposes numerous responsibilities on airport operators in terms of bird strike hazard prevention on air operations, thus placing airport operators in a “key position” in the system of safety. However, the party that suffers significant damages in the first instance, is the aircraft operator. If a bird strike takes place on or in the vicinity of an airport, an aicraft operator can sue the airport operator for compensation of damages. Generally, the issue of indemnity is subject to out of court negotiations, however instances in which there is a lack of agreement between the parties, i.e. airport operator, aircraft operator or their insurers, lead to legal proceedings for compensation.This article attempts to illustrate the relationship between air traffic participants such as airport operators and aircraft operators in connection with their obligations and liability, particulary taking into account the legal obligations of an airport operator.

    2009-01-01

    Continuing advances in airport surface management and improvements in airport surface safety are required to enable future growth in air traffic throughout the airspace, as airport arrival and departure delays create a major system bottleneck. These airport management and safety advances will be built upon improved communications, navigation, surveillance, and weather sensing, creating an information environment supporting system automation. The efficient movement of the digital data generated from these systems requires an underlying communications network infrastructure to connect data sources with the intended users with the required quality of service. Current airport surface communications consists primarily of buried copper or fiber cable. Safety related communications with mobile airport surface assets occurs over 25 kHz VHF voice and data channels. The available VHF spectrum, already congested in many areas, will be insufficient to support future data traffic requirements. Therefore, a broadband wireless airport surface communications network is considered a requirement for the future airport component of the air transportation system. Progress has been made on defining the technology and frequency spectrum for the airport surface wireless communications network. The development of a test and demonstration facility and the definition of required testing and standards development are now underway. This paper will review the progress and planned future work.

    The dishwasher is a useful home appliance and continually used for automatically washing dishes. It's commonly placed in the kitchen with built-in style for practicality and better use of space. In this environment, people are easily exposed to dishwasher noise, so it is an important issue for the consumers, especially for the people living in open and narrow space. Recently, the sound power levels of the noise are about 40 - 50 dBA. It could be achieved by removal of noise sources and passive means of insulating acoustical path. For more reduction, such a quiet mode with the lower speed of cycle has been introduced, but this deteriorates the washing capacity. Under this background, we propose active noise control for dishwasher noise. It is observed that the noise is propagating mainly from the lower part of the front side. Control speakers are placed in the part for the collocation. Observation part of estimating sound field distribution and control part of generating the anti-noise are designed for active noise control. Simulation result shows proposed active noise control scheme could have a potential application for dishwasher noise reduction.

    Incheon International Airport (ICN) is one of the hub airports in East Asia. Airport operations at ICN have been growing more than 5 percent per year in the past five years. According to the current airport expansion plan, a new passenger terminal will be added and the current cargo ramp will be expanded in 2018. This expansion project will bring 77 new stands without adding a new runway to the airport. Due to such continuous growth in airport operations and future expansion of the ramps, it will be highly likely that airport surface traffic will experience more congestion, and therefore, suffer from efficiency degradation. There is a growing awareness in aviation research community of need for strategic and tactical surface scheduling capabilities for efficient airport surface operations. Specific to ICN airport operations, a need for A-CDM (Airport - Collaborative Decision Making) or S-CDM (Surface - Collaborative Decision Making), and controller decision support tools for efficient air traffic management has arisen since several years ago. In the United States, there has been independent research efforts made by academia, industry, and government research organizations to enhance efficiency and predictability of surface operations at busy airports. Among these research activities, the Spot and Runway Departure Advisor (SARDA) developed and tested by National Aeronautics and Space Administration (NASA) is a decision support tool to provide tactical advisories to the controllers for efficient surface operations. The effectiveness of SARDA concept, was successfully verified through the human-in-the-loop (HITL) simulations for both spot release and runway operations advisories for ATC Tower controllers of Dallas-Fort Worth International Airport (DFW) in 2010 and 2012, and gate pushback advisories for the ramp controller of Charlotte-Douglas International Airport (CLT) in 2014. The SARDA concept for tactical surface scheduling is further enhanced and is being

    Wildlife incidents with aircraft cost the United States (U.S.) civil aviation industry >US1.4 billion in estimated damages and loss of revenue from 1990 to 2009. Although terrestrial mammals represented only 2.3 % of wildlife incidents, damage to aircraft occurred in 59 % of mammal incidents. We examined mammal incidents (excluding bats) at all airports in the Federal Aviation Administration (FAA) National Wildlife Strike Database from 1990 to 2010 to characterize these incidents by airport type: Part-139 certified (certificated) and general aviation (GA). We also calculated relative hazard scores for species most frequently involved in incidents. We found certificated airports had more than twice as many incidents as GA airports. Incidents were most frequent in October ( n = 215 of 1,764 total) at certificated airports and November ( n = 111 of 741 total) at GA airports. Most (63.2 %) incidents at all airports ( n = 1,523) occurred at night but the greatest incident rate occurred at dusk (177.3 incidents/hr). More incidents with damage ( n = 1,594) occurred at GA airports (38.6 %) than certificated airports (19.0 %). Artiodactyla (even-toed ungulates) incidents incurred greatest (92.4 %) damage costs ( n = 326; US51.8 million) overall and mule deer ( Odocoileus hemionus) was the most hazardous species. Overall, relative hazard score increased with increasing log body mass. Frequency of incidents was influenced by species relative seasonal abundance and behavior. We recommend airport wildlife officials evaluate the risks mammal species pose to aircraft based on the hazard information we provide and consider prioritizing management strategies that emphasize reducing their occurrence on airport property.

  11. Auxiliary power unit noise of Boeing B737 and B747 aircraft

    Science.gov (United States)

    Kwan, Jimmy S. W.; Yang, S. J. Eric

    Most modern civil aircraft have an Auxiliary Power Unit (APU) which provides compressed air for engine starting and the air-conditioning system on ground and electrical power for aircraft use both on-ground and in-fligth. It is basically a gas turbine engine and it consists of a compressor section, a turbine section, and an accessory drive section. For Boeing B737 and B747 aircraft, the APU is located inside a compartment in the tail section of the aircraft and is completely enclosed by a sound-reduction fire-proof titanium shroud. APU noise is one of the major noise sources at many airports and is extremely important for a densely populated city such as Hong Kong. The noise from APU can affect many people, including ground crew aircraft maintenance staff, and people living in the vicinity of the airport. However, there is very little information available in the literature about APU noise. This paper describes the noise measurement method and presents the measurement results for APUs of one B747 and two B737 aircraft under both 'loaded' and 'no-load' conditions.

  20. Input-Output Modeling and Control of the Departure Process of Congested Airports

    Science.gov (United States)

    Pujet, Nicolas; Delcaire, Bertrand; Feron, Eric

    2003-01-01

    A simple queueing model of busy airport departure operations is proposed. This model is calibrated and validated using available runway configuration and traffic data. The model is then used to evaluate preliminary control schemes aimed at alleviating departure traffic congestion on the airport surface. The potential impact of these control strategies on direct operating costs, environmental costs and overall delay is quantified and discussed.
