Abstract

In order to study lateral collision risk of closely spaced parallel runways (CSPRs) paired approach, a kinematic equation was established to describe motion process of aircraft and to determine time-varying intervals between them. Then, wake strength was simulated through large eddy simulation, wake vortex field characteristics of front aircraft and response mechanism of rear one which was disturbed by wake were analyzed, thus a moment balance model was established to determine safety area of wake. Finally, with lateral positioning error taken into consideration, lateral collision risk was calculated and analyzed by using basic principles of probability theory. The results show that the risk grows continuously during paired approach process and reaches maximum value at the last moment, and it increases as initial interval and positive crosswind increases. © 2020 China Safety Science Journal.
