Abstract
AbstractAlthough the application of new, reduced aircraft separation minima can directly increase runway throughput, the impact thereof on the traffic flow of aircraft arriving at the destination airport has not been discussed yet. This paper proposes a data-driven and queue-based modeling approach and presents an analysis of the impact on the delay time of arriving aircraft in the airspace within a radius of 100 nautical miles around an airport. The parameters of our queuing model were estimated by analysing the data contained in the radar tracks and flight plans for flights that arrived at Tokyo International Airport during the 2 years of 2016 and 2017. The results clarified the best arrival strategy according to the distance from the arrival airport: The combination of airspace capacity control and reduction of the flight time and separation variance is the most powerful solution to mitigate delays experienced by arriving traffic while also allowing an increase in the amount of arrival traffic. The application of new wake vortex categories would enable us to increase the arrival traffic to 120%. In addition, the arrival delay time could be minimised by implementing the proposed arrival traffic strategies together with automation support for air traffic controllers.
Highlights
Increasing the runway throughput is one of the most promising solutions to accommodate future air traffic growth
We model the traffic flow of aircraft arriving from within a radius of 100NM from the destination airport by means of a G/G/c queue, and provide a microscopic view of the analysis to clarify the optimal balance between increasing the arrival rate considering the airspace capacity, with the ultimate aim of minimising the delay in arrival time
This study has analysed arrival strategies to minimise the delay in aircraft arrival while allowing future growth in the amount of arrival traffic
Summary
Increasing the runway throughput is one of the most promising solutions to accommodate future air traffic growth. We model the traffic flow of aircraft arriving from within a radius of 100NM from the destination airport by means of a G/G/c queue, and provide a microscopic view of the analysis to clarify the optimal balance between increasing the arrival rate considering the airspace capacity, with the ultimate aim of minimising the delay in arrival time. This remainder of the paper is organised as follows. The total number of arrivals between 8:00AM and 11:00PM is slightly below the maximum allowed daily traffic threshold, and the most congested period is between 5:00PM and 10:00PM
