Aviation and climate change are often associated. The effects of climate change have increasing impact on the safe operation of airports. Due to both climate and weather conditions changes, airport winter maintenance is a significantly important activity of airports, especially in areas where a harsh winter season is expected. Continuous optimization of airport winter maintenance processes is necessary. The aim of this article is to present a possible way to optimize maintenance processes using simulation tools. The team of researchers identified key factors that are necessary for the application of the optimization. The article presents a procedure designed for safe handling of one of the model situations in winter maintenance of airports. The model of simulation defines critical points in the maintenance procedures designed for maintenance optimization using the data obtained from an international airport. Based on the determination of critical points of the maintenance procedures processed using a Gantt chart, the authors analyzed the differences of the performed procedures applied in the airport. The result of applied research is the identification of the next critical points in the simulation that may potentially represent critical activities of the winter maintenance procedure and have an influence on their optimization.

In line with the advancing airway capability, the non-aeronautical business opportunities at airports are also in growth. To attract more passengers or to generate extra income over non-aeronautical services, the airport decision-makers need to evaluate the quality of their services. This study aims at introducing an expanded approach to improve airport service quality aspects of the non-aeronautical business opportunities. Given the increasing number of airports, passengers prefer airports, which provide better or extra services compared to others. To reveal the airport service quality (ASQ) aspects, together with the quality department experts, we conducted a qualitative study that put forward six significant dimensions for an effective evaluation of airport service quality at an airport. Based on the results of the qualitative study, we designed the sector-specific questionnaire, and its empirical data is conducted over 250 passengers through a face-toface survey. Survey results introduce a practical assessment tool for the use of airport managers to gather strategic inputs on their strategic plans and quality implications. Results also contribute to the literature by presenting a comprehensive understanding of the airport service quality.

Full textAbstract:
Shortly after the passage of the Intermodal Surface Transportation Efficiency Act of 1991, the Federal Highway Administration and the Federal Aviation Administration recognized that there was very little guidance available for airport operators and metropolitan planning organizations (MPOs) to use for planning intermodal access to airports in the United States. As a result, the Intermodal Ground Access to Airports: A Planning Guide was developed. This Guide is designed to provide guidance to states, MPOs, and airport operators on the types of analyses that should be performed when airport access is being planned. It describes the airport access planning process and procedures for performing analyses. During the development of the Guide, relationships were developed between the level of originating passengers at American airports and the characteristics of airport access and landside facilities. The types of characteristics that were related to originating passengers included public parking, vehicle trips, terminal curbside design, and mode of access. Some of the relationships that were developed, how they were derived, and their importance to airport access planning are now presented. In addition, some additional relationships that should be developed are suggested.

Full textAbstract:
An airport gate is the core resource of an airport operation, which is an important place for passengers to get on and off the aircraft and for maintaining aircraft. It is the prerequisite for other related dispatch. Effective and reasonable allocation of gates can reduce airport operating costs and increase passenger satisfaction. Therefore, an airport gate assignment problem (AGAP) needs to be urgently solved in the actual operation of the airport. In this paper, considering the actual operation of the airport, we formulate an integer programming model for AGAP by considering multiple constraints. The model aims to maximize the number of passengers on flights parked at the gate. A tabu search-based algorithm is designed to solve the problem. In the process of algorithm design, an effective initial solution is obtained. A unique neighborhood structure and search strategy for tabu search are designed. The algorithm can adapt to the dynamic scheduling of airports. Finally, tests are performed using actual airport data selected from Kunming Changshui International Airport in China. The experimental results indicate that the proposed method can enhance the local search ability and global search ability and get satisfactory results in a limited time. These results provide an effective support for the actual gate assignment in airport operations.

Full textAbstract:
Community outreach and engagement efforts are critical to an airport’s role as an ever-evolving transportation infrastructure and regional economic driver. As online social media platforms continue to grow in both popularity and influence, a new engagement channel between airports and the public is emerging. However, the motivations behind and effectiveness of these social media channels remain unclear. In this work, we address this knowledge gap by better understanding the advantages, impact, and best practices of this newly emerging engagement channel available to airports. Focusing specifically on airport YouTube channels, we first document quantitative viewership metrics, and examine common content characteristics within airport YouTube videos. We then conduct interviews and site visits with relevant airport stakeholders to identify the motivations and workflow behind these videos. Finally, we facilitate sample focus groups designed to survey public perceptions of the effectiveness and value of these videos. From our four project phases, to maximize content effectiveness and community engagement potential, we synthesize the following framework of action items, recommendations, and best practices: (C) Consistency and community; (O) Organizational structure; (M) Momentum; (B) Branding and buy-in; (A) Activity; (T) Two-way engagement; (E) Enthusiasm; and (D) Depth, or as a convenient initialism, our COMBATED framework.

At this simulation, quality is built upon on a precisely defined model of airport processes are set forth by the authors as part of the process of designing a modern Departure Control System (DCS) of airports, which currently designated for automation of a complex management of processes in the field of passenger and baggage handling, the airports offer to individual air carriers. The resulting algorithms designed for the separate separate processes of the DCS will help the authors understand real processes taking place at the airport with the aim to optimize the course of actions at the airport operation. A precisely built model of airport processes is the prerequisite of proper implementation of the simulation, pointing out both the advantages and disadvantages of this models and their implementation in practice.

Full textAbstract:
Airport is a vital subsystem in the air transport system which has an important and strategic role in smoothening air traffic, so that an airport must be designed to be always ready in all situations and conditions to serve airline flights securely, orderly, smoothly, and quickly. The frequent delay faced by Indonesian domestic scheduled airlines is not fully caused by internal factor of the companies. Instead, it can be caused by the airport factor. The problems faced by airports in Indonesia which have impacts on the performance of flight punctuality among other things are capacity, slot time, quality of flight navigation devices, accessibility, professionalism of airport and ATC human resources, infrastructure, facilities, equipment, and the human resources handling security and safety of flights in airport. This article recommends that an in-depth study should be carried out to map the interrelations between the airport factor in the flight delay related to facilities integration and the airport authority in the flight activities in Indonesia.

Full textAbstract:
In this study, we describe the results of a questionnaire distributed among European airports in the autumn of 2019. The questionnaire was designed to elicit airports’ views on the practicalities of competition between airports. We received 49 responses from airports in 24 countries; the respondents represent airports of different sizes. The survey results evidence behaviours consistent with significant competition between airports. Airports are taking active steps through their resourcing and staffing, incentives and marketing to attract airline services, and clearly see themselves taking the initiative in doing so. No airport, no matter how large, appears to be able to escape competition. The main policy message of our study, consistent with other recent reviews of airport competition, is that European regulators should re-evaluate their approach to the economic regulation of airports, especially as far as regional airports are concerned.

Full textAbstract:
Abstract The present paper focuses on spatial management regulations in order to carry out investment in the field of airport facilities. The construction, upgrades, and maintenance of airports falls within the area of responsibility of local authorities. This task poses a great challenge in terms of organisation and finances. On the one hand, an active airport is a municipal landmark and drives local economic, social and cultural development, and on the other, the scale of investment often exceeds the capabilities of local authorities. The immediate environment of the airport determines its final use and prosperity. The objective of the paper is to review legislation that affects airports and the surrounding communities. The process of urban planning in Lodz and surrounding areas will be presented as a background to the problem of land use management in the vicinity of the airport. This paper seeks to address the following questions: if and how airports have affected urban planning in Lodz, does the land use around the airport prevent the development of Lodz Airport, and how has the situation changed over the time? It can be assumed that as a result of lack of experience, land resources and size of investments on one hand and legislative dissonance and peculiar practices on the other, aviation infrastructure in Lodz is designed to meet temporary needs and is characterised by achieving short-term goals. Cyclical problems are solved in an intermittent manner and involve all the municipal resources, so there’s little left to secure long-term investments.

Full textAbstract:
Abstract All of the pollutants found in stormwater runoff at airports, including surface and aircraft de-icing/anti-icing glycols, can be treated and removed to low levels in well-designed sub-surface flow (SSF) constructed wetland systems. There are two common forms of constructed wetlands used for pollution control: those where water flows over the surface among wetland plants (free water surface or marsh type wetlands); and SSF types where the wastewater flows below the normally dry surface of a gravel substrate in which the wetland plants grow. SSF wetlands have no open water to attract waterfowl and are particularly suitable for use at airports. Of the glycol used at Edmonton International Airport (EIA), 80 to 90% eventually entered surface runoff. Edmonton International Airport's operator, the Edmonton Regional Airports Authority (Edmonton Airports) evaluated a number of glycol management options, including constructed wetlands. As a result, a very large SSF wetland system was installed to handle glycol-contaminated stormwater. This paper reviews results of a feasibility study carried out to define design parameters and scale up kinetics for this wetland system, the detailed design that resulted, the SSF wetland's construction, and the start-up of the Edmonton facilities in August of 2000. It also compares the Edmonton wetland system with a similar facility at Heathrow Airport in the United Kingdom.

Full textAbstract:
Over the past few decades, digital tools have become indispensable in the field of architecture. The complex design tasks that make up architectural design methods benefit from utilizing advanced simulation software and, consequently, design solutions have become more nature-adapted and site-specific. Computer simulations and performance-oriented design enable us to address global challenges, such as climate change, in the preliminary conceptual design phase. In this paper, an innovative architectural design method is introduced. This method consists of the following: (1) an analysis of the local microclimate, specifically the wind situation; (2) the parametric shape generation of the airport terminal incorporating wind as a form-finding factor; (3) Computational Fluid Dynamics (CFD) analysis; and (4) wind-performance studies of various shapes and designs. A combination of programs, such as Rhinoceros (Rhino), and open-source plug-ins, such as Grasshopper and Swift, along with the post-processing software Paraview, are utilized for the wind-performance evaluation of a case study airport terminal in Reykjavik, Iceland. The objective of this wind-performance evaluation is to enhance the local wind situation and, by employing the proposed architectural shape, to regulate the wind pattern to find the optimal wind flow around the designed building. By utilizing the aforementioned software, or other open-source software, the proposed method can be easily integrated into regular architectural practice.

Purpose Travelers are both surrounded by and perform places, thus making places ambiguous sites that “come alive” when travelers use them and engage in various performances. A place many travelers pass through is the airport. Airports are places where travelers’ performances are restricted in many ways and waiting is a key element of the airport experience. This paper contributes with knowledge on what airport terminals “are”, not as designs or material objects but as places enacted by travelers. In doing so, the paper aims to emphasize on both how travelers “see” airports and how they use them. Design/methodology/approach The study uses different qualitative methods and notions of time and waiting. Sources of data are small-scale netnography, focus group interviews, observations done at airports and qualitative interviews. Findings The study shows that airport terminals are heterogeneously enacted environments that are heavily inscribed with the mundane act of waiting and travelers use a series of different strategies to “use”, “spend” and “kill” time. Furthermore, whereas more affluent travelers spend waiting time using airports’ commercial offerings (shopping, restaurants, bars, etc.), less affluent travelers do not have the same options. Research limitations/implications The research points to airport terminals as not only “places of movement and mobility” but also “places of waiting” inscribed with boredom and travelers actively fight boredom by spending, using and killing time in a variety of ways. Furthermore, the study points to significant differences between affluent travelers and other travelers and differences between people travelling alone and in groups. Therefore, a call is made for research focusing on less affluent travelers, people traveling in groups and on waiting and waiting time. Practical implications The study suggests that airports are more than consumerscapes and places of movement, hereby questioning the current focus on commercial revenues. Social implications The study points to airport space as space “inhabited” not only by travelers willingly taking on the roles as consumers but also by travelers that kill, spend and use waiting time in other ways, hereby questioning the idea that airports are places for the “elite”. Originality/value Travelers associate airports with boredom and inscribe them with waiting. However, travelers “fight” boredom and waiting with performances and acts designed to use, spend, pass and “kill” time. Hereby, travelers not only accept but also construct the seemingly mundane act of waiting as restricted, negotiated and confined, but nevertheless meaningful performances.

Full textAbstract:
Integrated development and operational collaboration of regional airport groups have the potential to improve capacity and safety and also reduce environmental impacts and operational costs. However, research in multiairport systems (MASs), especially in China, is still in its infancy, with the consequences of unbalanced development, inadequate coordination, unclear function partitioning, difficulty in air traffic management, and poor service quality of regional airports. Considering these characteristics influencing effective interaction and collaboration of regional airports, this paper formulates a model to optimize the flight schedules in the MAS with multiple objectives of minimizing the maximum displacement of all flights, the weighted sum of total flight adjustment of each airport, and flight delays. An improved simulated annealing algorithm (SAA) is designed to solve the proposed multiobjective optimization problem. The model is applied to a case of the Beijing-Tianjin-Hebei Airport Group. The computational results demonstrate that the model generates significant reductions in maximum displacement, average displacement, and average delay, compared to the First-Come-First-Served (FCFS) principle. The model proposed in this paper can be used by civil aviation authorities, air navigation service providers, and airlines to facilitate the integrated management of flight schedules in the MAS.

Purpose This study aims to propose a new airport gate assignment method to effectively improve the comprehensive operation capacity and efficiency of hub airport. Gate assignment is one of the most important tasks for airport ground operations, which assigns appropriate airport gates with high efficiency reasonable arrangement. Design/methodology/approach In this paper, on the basis of analyzing the characteristics of airport gates and flights, an efficient multi-objective optimization model of airport gate assignment based on the objectives of the most balanced idle time, the shortest walking distances of passengers and the least number of flights at apron is constructed. Then an improved ant colony optimization (ICQACO) algorithm based on the ant colony collaborative strategy and pheromone update strategy is designed to solve the constructed model to fast realize the gate assignment and obtain a rational and effective gate assignment result for all flights in the different period. Findings In the designed ICQACO algorithm, the ant colony collaborative strategy is used to avoid the rapid convergence to the local optimal solution, and the pheromone update strategy is used to quickly increase the pheromone amount, eliminate the interference of the poor path and greatly accelerate the convergence speed. Practical implications The actual flight data from Guangzhou Baiyun airport of China is selected to verify the feasibility and effectiveness of the constructed multi-objective optimization model and the designed ICQACO algorithm. The experimental results show that the designed ICQACO algorithm can increase the pheromone amount, accelerate the convergence speed and avoid to fall into the local optimal solution. The constructed multi-objective optimization model can effectively improve the comprehensive operation capacity and efficiency. This study is a very meaningful work for airport gate assignment. Originality/value An efficient multi-objective optimization model for hub airport gate assignment problem is proposed in this paper. An improved ant colony optimization algorithm based on ant colony collaborative strategy and the pheromone update strategy is deeply studied to speed up the convergence and avoid to fall into the local optimal solution.

The government of Indonesia plans to build new airport that is located in Temon Sub-district, Kulon Progo Regency. However, the distance of the airport is quite far from the center of Yogyakarta City, therefore it is necessary to build a railway that functioned as a connector. The operating airport railway would then means an Airport Railway Station that is located in the center of Yogyakarta City, in order to accommodate the fluency of railway operation. This paper is intended to give information on the layout design, and also the location of Airport Railway Station in the center of Yogyakarta City. To generate layout of railway that is integrated with Tugu Railway Station of Yogyakarta, the methods used were: determining the station classification, determining the zone, the circulation and wayfinding, so that the passengers could move fluently. Based on the analysis result, the Airport Railway Station has categorized a large class station, with its location was designed separately from the Tugu Railway Station, but integrated with 52 meters long tunnel in south of the Airport Railway Station. The layout design of the Airport Railway Station was designed to be two levels and with two platforms with land necessity of 9100 m2, and was predicted to serve 515 passengers per rush hour.

Full textAbstract:
To guarantee the operation safety of airport, improve the efficiency of surface operation, and enhance the fairness of taxiing route scheduling, an optimizing model is established for the airport surface taxiing route scheduling. Reducing the total aircraft taxiing route length and reducing the waiting delay time are the goals of the model by controlling the initial taxiing time of aircraft and choosing the right taxiing route. The model can guarantee the continuous taxiing for all aircraft without conflicts. The runway scheduling is taken into consideration in the model to optimize the surface operation. The improved genetic algorithm is designed for simulation and validation. The simulation results show that compared with the ant colony optimization method, the improved genetic algorithm reduces the total extra taxiing distance by 47.8% and the total waiting delay time decreases by 21.5%. The optimization model and improved genetic algorithm are feasible. The optimization of taxiing route method can provide decision support for hub airports.

The major goal of air traffic management is to strategically control the flow of airport traffic. Airport capacity management (ACM) in a dynamic environment is crucial for the optimal operation in airport environment. This paper uses the concept of dynamic receding horizon control (DRHC) to conduct real-time planning for airport capacity management. A gene algorithm is then designed from DRHC point of view. It is shown that DRHC provides a generic and flexible framework for developing real-time allocation algorithms for airport capacity in a dynamic and uncertain environment. Simulation results show that the algorithm is effective and efficient to solve the problem.

Full textAbstract:
The disturbances, caused by resource competition, weather changes, and demand uncertainties, frequently occur and result in obvious fluctuations (e.g., the increase or decrease of demand and capacity) in demand and capacity. This work addresses the problem of aircraft rerouting and rescheduling in presence of disturbances, characterized by the increase or decrease of demand and capacity, at a multi-airport terminal maneuvering area (TMA). A multi-objective optimization model is proposed to minimize the total flight delays and total extra flying time, considering the aircraft wake turbulence separation, runway operation rules, air traffic control regulations, scheduling time windows, and airport/airspace capacity, etc. Based on the non-dominated sorting genetic algorithm (NSGA-II), we designed an efficient evolutionary algorithm to solve the proposed model and search the Pareto solutions. Five scenarios are designed to analyze and compare the operation performance under normal and disturbed conditions, using the classic First-Come-First-Served (FCFS) and optimized scheduling (OPTS) methods. A case study is conducted for Shanghai Pudong and Hongqiao Airports, and the computational results show that, compared with the FCFS method, the proposed OPTS method significantly performs a overall better performance in minimizing total flight delay and total extra flying time, while slightly inferior in optimizing the delay and extra flying time of one single flight.

An optimization model of airport shuttle bus routes is constructed by taking operational reliability maximization as a main goal in this paper. Also, a hybrid genetic algorithm is designed to solve this problem. Then the theoretical method is applied to the case of Nanjing Lukou International Airport. During the research, a travel time reliability estimation method is proposed based on back propagation (BP) neural network. Absolute error and regression fitting methods are used to test the measurement results. It is proved that this method has higher accuracy and is applicable to calculate airport bus routes reliability. In algorithm design, the hill-climbing algorithm with strong local search ability is integrated into genetic algorithm. Initial solution is determined by hill-climbing algorithm so as to avoid the search process falling into a local optimal solution, which makes the accuracy of calculation result improved. However, the calculation results show that the optimization process of hybrid genetic algorithm is greatly affected by both the crossover rate and mutation rate. A higher mutation rate or lower crossover rate will decrease the stability of the optimization process. Multiple trials are required to determine the optimal crossover rate and mutation rate. The proposed method provides a scientific basis for optimizing the airport bus routes and improving the efficiency of airport’s external transportation services.

Aviation promotes trade and tourism by connecting regions, people, and countries. Having a functional and efficient airport pavement network is important to improve aviation traffic and to provide safer mobility to almost 800 million passengers travelling in the U.S. per year. The Federal Aviation Administration has initiated and actively been participating in many projects to further advance pavement design and performance to meet user requirements. To accomplish that, quantitative data are needed; such data may be collected from the pavement response to gear and environment loading. In this study, responses from four instrumented taxiway concrete slabs at John F. Kennedy International Airport were analyzed. The collected data were used to develop machine-learning (ML) based prediction models to compute the temperature, curling and bending strains within pavement. The ML models were developed using the support vector machine (SVM) algorithm. The results showed that SVM based ML models can predict pavement responses with a high accuracy and low computation time. Furthermore, in the case of feeding more data from various airports, ML models have proven to be a promising technique for pavement analysis engine for future airport pavement design frameworks. This study also produces recommendations for future data collection projects to have well-designed databases for data-driven models development.

Background: Shifting travellers from air to rail can reduce environmental impacts and is an important European Union goal. Online travel planning applications allow travellers to easily compare air and rail transport choices, however, they may not accurately consider time travellers spend at the airport or railway station since these depend on buffer times travellers use to protect against delays. Methods: This research investigated the actual time spent at airports and railway stations to analyse the accuracy of travel planning applications and help improve the quality of travel time estimates.The research used a travel time recording application to determine the time spent by passengers at airports and railway stations. Data was collected for 312 trips. The research was supplemented by an extensive literature review of dwell times and multimodal travel planning applications. Results: The research found that travellers spent an average of 157 minutes at airports and 32 minutes at railway stations. Comparing these results to travel planning application, the information shows that the applications significantly underestimate time spent at airports and slightly underestimate time spent at railway stations.The use of unrealistic airport waiting times in travel planning applications distorts traveller perception in favour of air travel. Conclusion: Therefore, railway operators should support the development of improved travel planning applications that better consider waiting times. Improving these applications would be much more cost effective than infrastructure improvements designed to save a few minutes of travel time.

Second, a low and slow small-target self-identification and tracking technology is constructed against a complex environment. Based on the You Only Look Once (YOLO) and Kernel Correlation Filter (KCF) algorithms, an autonomous target recognition and high-speed tracking plan with great robustness and high reliability is designed. Third, a PTZ controller and automatic aiming strategy based on Anti-Windup Proportional Integral Derivative (PID) algorithm is designed, and a simplified, automatic-aiming expelling device, the environmentally friendly gel ball blaster, which features high speed and high accuracy, is built. The feasibility and stability of the project can be verified through prototype experiments.

Abstract Recently urban waterlogging problems have become more and more serious, and the construction of an airport runway makes the impervious area of the airport high, which leads to the deterioration of the water environment and frequent waterlogging disasters. It is of great significance to design and construct the sponge airport with low impact development (LID) facilities. In this paper, we take catchment N1 of Beijing Daxing International Airport as a case study. The LID facilities are designed and the runoff process of a heavy rainfall in catchment N1 is simulated before and after the implementation of LID facilities. The results show that the total amount of surface runoff, the number of overflow junctions and full-flow conduits of the rainwater drainage system in catchment N1 of Beijing Daxing International Airport are significantly reduced after the implementation of the LID facilities. Therefore, the application of LID facilities has greatly improved the ability of the airport to remove rainwater and effectively alleviated the risk of waterlogging in the airport flight area. This study provides theoretical support for airport designers and managers to solve flood control and rainwater drainage problems and has vital practical significance.

Abstract The structures of the airport pavements are designed for defined operational time, assuming the predicted intensity and structure of the air traffic. The safety of air operations conducted by aircrafts on airport pavements depends mostly on their load capacity and design. Therefore, the load capacity inspections should be performed periodically, as the information about the current operational condition of the airport pavement is the basis for decisions on types of aircrafts allowed for traffic, as well as traffic intensity and dates of renovation or modernization works. Currently, the load capacity of airport pavements is assessed with the use of the ACN-PCN method, implemented by the ICAO (International Civil Aviation Organization).

At present, hub airport is facing a lot of emergency situations, e.g., the management of irregular flight, which affects the sustainable development of the airport. Most of the methods for evaluating the robustness of airport gate assignment have been proposed by giving an independent evaluation function based on their experience, and thus, subjective factors are involved in varying degrees. Therefore, this paper puts forward an objective evaluation method based on the analysis of airport flight arrival, which gives a digital transformation strategy for the airport resource scheduling. A novel evaluation method based on data analysis of flight arrival time, and a mathematical model are formulated accordingly. In order to solve the proposed NP-hard problem, a new hybrid genetic algorithm combined with a heuristic algorithm is designed. In numerical experiments, the actual flight data of an international hub airport are used to analyze and verify the effectiveness of the proposed method. The results showed the advantages in scheme stability, operating cost savings, and risk reduction of the proposed method.

Quite often there is an oversaturation of the platform with ground aircraft, which is designed for the operation of modern international airports, especially in the so-called "rush hour". The emergence of such a situation may affect the emergence of risks in the implementation of airport technologies, which are associated with a probable reduction in the level of safety of ground vehicles on the platform, the formation of clusters of aircraft maintenance at the parking lot and the possibility of damage to aircraft on the ground, psychological stress aviation personnel and other unforeseen situations. To avoid melon situations that are directly related to the possible danger at airports, it is necessary to use multifunctional models of aviation ground equipment, which will provide several technological processes for ground handling of aircraft, passengers, mail and cargo by creating hybrid structures of special vehicles and equipment. and automation. For example, the use of multifunctional telescopic ladders allows not only to ensure a high level of comfort when boarding / disembarking passengers in aircraft, but also significantly increase the parking space in the buffer area of ground maintenance of aircraft for other types of ground aircraft by reducing the latter, which will increase the level of safety of aircraft maintenance and economic efficiency in the activities of airport services and handling companies.

After outbreak of severe acute respiratory syndrome (SARS) in 2003, many international airport quarantines adopted fever-based screening to identify infected individuals using infrared thermography to control global pandemic. Unfortunately, the sensitivity of fever-based screening system did not exceed 70.4% at Narita International Airport. In order to achieve accurate onboard entry screening for highly contagious infectious diseases, the authors developed a portable system designed for onboard entry screening with linear discriminant analysis. Within several tens of seconds, the system automatically discriminates infected individuals from normal subjects using measured heart rate, respiratory rate, as well as facial surface temperature determined by thermography. The size of system is small enough to be placed on airplane tray tables. The authors tested on 68 subjects including 12 influenza patients to evaluate the system. The result showed sensitivity of 91.7% and specificity of 92.9%. The system seems to be promising for onboard infection screening to safeguard public health.

Air traffic controllers aim to optimize airport capacity, that is to increase the number of aircraft movements per hour maintaining a limited delay. There are several definitions of capacity, which depend on the considered airport element. This study focused on the development of a method that allows evaluating the impact of tower air traffic controllers’ workload on airport capacity. It adapts a model for the workload of sector controllers designed by Eurocontrol to tower controllers and tests it on a heavily busy international airport. In order to collect controllers’ working times, a campaign of data collection has been carried out from the radio frequency occupation. The results allowed us to extrapolate the hourly percentage of work of the various tower controllers using a fast-time simulation software. By imposing an hourly working threshold on tower air traffic controllers, it was possible to obtain a maximum number of manageable aircraft, which was compared with the airside capacity of the airport. The results show that the maximum traffic manageable from the airside would produce unacceptable workload for tower controllers, highlighting the link between airport capacity and the human component.

Beijing Capital International Airport is one of the busiest hub airports in the world, but its capacity is limited. Reducing the minimum radar interval during instrument approaches would be feasible to increase capacity. The airport has three parallel runways; the distance between runways 36L/18R and 01/19 is 3.485 km. Currently, because there is no final monitoring seat, the dependent parallel instrument approach mode is adopted on the two runways; approaching aircraft must maintain a 4 km safety separation. This paper focuses on whether the 4 km radar safety separation for parallel instrument approaches could be reduced to 3.485 km without the final monitoring. This would mean implementing independent instrument approach operations between the two runways. To consider this, a new collision risk model based on position error probability and aircraft kinematics is proposed. A test program to acquire data on controllers’ reaction times in abnormal situations was designed and implemented over 10 days by the North China Air Traffic Management Bureau (ATMB). Furthermore, six months of radar trajectory data was collected at the airport. This was analyzed and processed to obtain the position error, speed, and other parameters required for the calculation of the collision risk model. The results show that the independent instrument approach operations between runways 36L/18R and 01/19 would be feasible the within safety target level set by the International Civil Aviation Organization (ICO). Based on the theoretical research results, the North China ATCB implemented independent instrument approaches between runways 36L/18R and 01/19 on December 25, 2018; it has operated safely since.

At the John F. Kennedy International Airport in New York City, disaster planning has been an integral part of the airport operations for the past 28 years. Through the Medical Office, emergency medical teams have been recruited from all ranks of airport personnel and trained in rescue and resuscitation. Following the crash of a commercial B 727 aircraft in 1976 and the resulting crippling traffic jams in the vicinity of the airport, a new concept was added to the disaster plan. This concept involves bringing the hospital, its facilities and its personnel to the scene.A new piece of equipment, known as a Mobile Emergency Hospital was designed from existing airport equipment, with the cooperation of the airlines, the operating authority of the airport, and other interested parties. Two such vehicles are now in constant readiness at the airport and together provide 12 monitored ICU beds, a 16-bed burn unit, 2 operating rooms and 72 other stretcher-beds to be used for the stabilization of critically ill patients prior to their transfer to an appropriate definitive care facility. A newer modularized version which incorporates these features, for use in any type disaster, is currently being developed. These mobile hospitals, together with two inflatable structures maintained at the airport, are supplemented by Mobile Emergency Rescue Vehicles (MERV vans) maintained at local hospitals by the Emergency Medical Service Systems (EMSS) of New York City. Together they provide the on-site Resuscitation and Stabilization Center in the event of a disaster.

We describe an ongoing research effort pertaining to the development of a surface traffic automation system that will help controllers to better coordinate surface traffic movements related to arrival and departure traffic. More specifically, we describe the concept for a taxi-planning support tool that aims to optimize the routing and scheduling of airport surface traffic in such a way as to deconflict the taxi plans while optimizing delay, total taxi-time, or some other airport efficiency metric. Certain input parameters related to resource demand, such as the expected landing times and the expected pushback times, are rather difficult to predict accurately. Due to uncertainty in the input data driving the taxi-planning process, the taxi-planning tool is designed such that it produces solutions that are robust to uncertainty. The taxi-planning concept presented herein, which is based on mixed-integer linear programming, is designed such that it is able to adapt to perturbations in these input conditions, as well as to account for failure in the actual execution of surface trajectories. The capabilities of the tool are illustrated in a simple hypothetical airport.

Abstract sonAIR is a recently developed aircraft noise simulation model designed for single flight simulation while still being applicable for calculation of entire airport scenarios. This paper presents a rigorous validation exercise, wherein roughly 20’000 single flights were simulated using the 22 currently available sonAIR emission models of turbofan aircraft and compared against noise measurements. The measurements were recorded with the noise monitoring terminals at Zurich and Geneva airport, Switzerland, and with additional microphones installed by the author’s institution. Data from 22 measurement positions were analyzed, covering all departure and approach routes at distances from 1.8 to 53 kilometers from the airports. sonAIR was found to be accurate for departures and approaches under different operating conditions and aircraft configuration. The mean overall differences between simulation and measurements were well below ±1 dB in terms of noise event levels, with standard deviations of ±1.7 dB respectively ±2.4 dB, depending on the model type. A few aircraft types that displayed larger deviations are discussed individually. A sensitivity analysis on the input data found the quality and level of detail of the land cover data to be critical for the simulation accuracy. Changes in other input data such as atmospheric profiles and buildings had non-significant impacts.

Abstract Intensive exploitation of coal beds in the Upper Silesia Coal Basin led to the degradation of the Katowice-Muchowiec civilian/military airport. As a result, it became necessary to adapt the Pyrzowice military airport for use as a public transport facility. This involved reconstruction of a hangar located at the airport. As part of this process, a new hangar slab was constructed, designed in such a way as to bear the load of passenger aircraft. In the area of the greatest wheel load to the slab, three strain rosettes were installed for the purpose of monitoring the slab strain. The mointoring process - which has been automatically conducted for almost three years now - revealed deformations resulting from service load, the aging of reinforced concrete, and changes of its temperature.

Contemporary analyses of citizenship emphasise the importance of being able to occupy public space in a manner that does not compromise one’s sense of self. Moreover, they foreground individuals’ active engagement with others (e.g., being concerned about others) and the active exercise of one’s rights. We explore such issues through considering the psychological and social significance of having one’s various self-definitions mis-recognised in everyday social interactions. We do so through reporting interview and focus group data obtained from Scottish Muslims concerning their experience of surveillance at airports. Focussing on their accounts of how they orient to others’ assumptions about Muslim passengers, we consider what this means for our participants’ ability to act on terms that they recognise as their own and for their citizenship behaviours. Our analysis is organised in two sections. First, we examine the strategies people use to avoid painful encounters inside the airport. These include changes in micro-behaviours designed to avert contact, and where this was not possible, identity performances that are, in various ways, inauthentic. Second, we examine citizenship-related activities and how these may be curtailed in the airport. These include activities that entail the individual reaching out and making positive connections with others (e.g., through helping others) and exercising the right to criticise and complain about one’s treatment. Our analyses highlight the psychological and social consequence of identity misrecognition, and how this impacts on individuals’ abilities to act in terms of their own valued identifications and enact citizenship behaviours.
