Research on Approach Flight Sequencing for Point Merge System under RECAT-CN Wake Separation
In order to enhance the operation efficiency of terminal area approach flights,an approach flight sequencing model is designed for the terminal area point merge system of Dalian airport.The genetic algo-rithm is improved to solve the optimal sequencing of the actual flight sequence,proposing a flight se-quence switching operation mode.The following conclusions were drawn by comparing the operational effi-ciency of the flight sequence switching operation mode with the First Come First Served(FCFS)operat-ing mode at the RECAT-CN separation and the CAAC separation,respectively:1)The implementation of the flight sequence switching operation mode under the CAAC separation optimizes the total flight waiting time,total flight time,and total flight stream operation time compared with the FCFS operation mode.2)The use of RECAT-CN separation in the flight sequence switching operation mode can further improve the operation efficiency.3)The flight sequence switching operation mode can somewhat alleviate the prob-lem of gradual accumulation of flight delays under the FCFS operation mode.
