An airborne inter-arrival spacing tool was developed by NASA Langley Research Center to aid pilots in maintaining a time-based spacing interval behind another aircraft in the arrival sequence. A number of display features, including numeric speed commands, a speed pointer on the Fast/Slow Indicator, and graphical depiction of the desired aircraft position on the navigation display, were developed to assist pilots in maintaining the proper speed to achieve the required spacing interval. Because the use of such automated tools requires the acceptance of the user population, a study was conducted to assess the impact on user workload and acceptability. The tool was tested in a full-task simulation in a Boeing-757 full-mission, fixed-base simulator. Subject pilots were paired with a confederate pilot to complete tasks in both the pilot flying and pilot not flying positions. This paper presents the subjective evaluations of the inter-arrival spacing tool. The qualitative workload data from eight current B-757 airline pilots are compared from the perspectives of tool usability and acceptability, and the ability to attain and maintain the appropriate time interval spacing. Results of the study indicate that the pilots who participated in the study were comfortable using the Advanced Terminal Area Approach Spacing (ATAAS) tool and were confident in the automated spacing guidance that the tool provided. The ATAAS tool did not increase perceived pilot workload as compared to an approach conducted under standard (current-day) conditions.

The impact of unfavorable factors of aviation flight causes a significant strain in the flight crew of the functional state of the body, including various parts of the immune system. To date, research on the problems of interaction between different parts of the immune system in flight personnel in the process of professional adaptation is practically absent. In this regard, a study was conducted of immunological reactivity according to calculated data from 100 pilots of fighter aircraft and 102 pilots of other types of aircraft. The data obtained indicate significant dissociation of the flight composition in the immune system and changes in its reactivity. Studies of immunological reactivity in terms of integral leukocyte indices seem promising and, in combination with other methods of clinical and functional diagnostics, will expand the possibilities of assessing the overall functional status of pilots in the process of medical examination.

The ability for an aircraft to fly during a much extended period of time has become a key issue and a target of research, both in the domain of civilian aviation and unmanned aerial vehicles. This paper describes a new design and evaluating of solar wind aircraft with the objective to assess the impact of a new system design on overall flight crew performance. The required endurance is in the range of some hours in the case of law enforcement, border surveillance, forest fire fighting or power line inspection. However, other applications at high altitudes, such as geomatic operations for delivering geographic information, weather research and forecast, environmental monitoring, would require remaining airborne during days, weeks or even months. The design of GNSS non precision approach procedure for different airports is based on geomatic data.

Approach Route

With the air transport industry developing dramatically, the problem of flight congestion in the terminal area (TMA) has been aggravated. Particularly for arrival aircraft, the extraholding and delay not only increase the workload of air traffic controllers and aircrew but also reduce the operational efficiency. To struggle with this issue, it is crucial to study how to improve the operational efficiency of arrival aircraft. Under the background of the rapid promotion of Point Merge (PM) procedure program in the busy TMAs in the world, this paper firstly combines the optimization of PM procedure and arrival aircraft sequencing, aiming to maximize the operational benefits of arrival aircraft in TMA. Firstly, the framework of the PM procedure is set up to replace the traditional approach route known as Standard Instrument Arrival (STAR). After that, the PM procedure optimization model is established to provide a better approach route for each arrival aircraft. Then for a flow of arrival traffic, an aircraft sequencing model is established to readjust the landing sequence of arrival aircraft, thus further improving the operational benefits of arrival aircraft. Finally, taking the TMA of Shanghai Hongqiao International Airport as the case, we compare the impact of different flight procedures and different landing sequences on the operational benefits of arrival aircraft. The experimental results show that the application of the PM procedure optimization model and sequencing model can effectively improve the operational benefits on the premise of ensuring safety, thus realizing the safe and orderly approach in TMA.

Although the application of new wake turbulence categories, the so-called “RECAT (wake turbulence category re-categorization)”, will realize lower aircraft separation minima and directly increase runway throughput, the impacts of increasing arrival traffic on the surrounding airspace and arrival traffic flow as a whole have not yet been discussed. This paper proposes a data-driven simulation approach and evaluates the effectiveness of the lower aircraft separation in the arrival traffic at the target airport. The maximum runway capacity was clarified using statistics on aircraft types, stochastic distributions of inter-aircraft time and runway occupancy time, and the levels of the automation systems that supported air traffic controllers’ separation work. Based on the estimated available runway capacity, simulation models were proposed by analyzing actual radar track and flight plan data during the 6 months between September 2019 and February 2020, under actual operational constraints and weather conditions. The simulation results showed that the application of RECAT would reduce vectoring time in the terminal area by 7% to 10% under the current airspace and runway capacity when following a first-come first-served arrival sequence. In addition, increasing airspace capacity by 10% in the terminal area could dramatically reduce en-route and takeoff delay times while keeping vectoring time the same as under the current operation in the terminal area. These findings clarified that applying RECAT would contribute to mitigating air traffic congestion close to the airport, and to reducing delay times in arrival traffic as a whole while increasing runway throughput. The simulation results demonstrated the relevance of the theoretical results given by queue-based approaches in the authors’ past studies.
