Research On Runway Capacity Estimation Based On Wake Turbulence

The continuous increase of civil aviation transportation demand makes the evaluation of runway capacity very critical.The wake separation has a great impact on runway capacity.This paper studies the multi-runway capacity of an airport in Southwest China based on historical statistical data,mathematical model and computer simulation model.Mainly by analyzing the structure of large busy multi-runway airports in China,the runway capacity model is obtained.At the same time,the runway capacity models under different operating modes are analyzed in detail and constructed respectively.Ultimately,The results of the dependent parallel approach-independent departure mode and independent parallel approach-independent departure mode for different runway directions are obtained.Then,the Airtop simulation platform was used to simulate the runway capacity of the three-runway airports,and the simulation-based runway capacity was compared to historical data and mathematical model-based capacity.The theoretical maximum runway capacity for three-runway airports under different methods is obtained.Finally,the aircraft wake separation is analyzed as a key factor to improve the runway capacity based on the constructed three-runway airport runway capacity model.Then the airport runway capacity model based on the wake separation is obtained.And the airport runway capacity based on the ICAO and RECAT wake separation are compared and draw corresponding conclusions.
