Operation Strategies of the End-around Taxiway for Short-distance Parallel Runways
In order to provide theoretical basis for developing and optimizing aircraft surface operation strategies for close range par-allel runway airports,improve the safety and efficiency of runway operation,reduce airport operation surface conflicts,and reduce safe-ty hazards.Based on the goal of the minimum average ground taxiing time for inbound and outbound flights,an operation strategy model of the end-around taxiway(EAT)was analyzed and established.The feasibility of the model was verified by performing both numerical calculations and software simulations run by AirTOp software using two close parallel runways at an airport with the EAT as an example.The results of the numerical calculations show that the EAT strategies determined by the model can simultaneously reduce the delay level of inbound and outbound flights and improve ground taxiing efficiency.Through further study on the flight operation data of the airport demonstrates that a more obvious positive correlation exists between takeoff runway traffic density and the EAT utilization rate.Therefore,a EAT operation strategy was proposed for this airport under peak hourly operating sorties and variations in takeoff/landing ratios.
