3D Optimization Method for Terminal Arrival and DepartureRoute Network

In order to improve the safety efficiency and automation level of the design of flight path in terminal airspace,the optimization method of 3D routes network is studied. In view of optimizing independent route, this paper uses ant-colony algorithm to optimize safe and economic route horizontally. According to the vertical profile data of the routes in the terminal airspace, the paper presents an optimal method of 3D routes vertical profile based on the Kernel Density Estimation. After the analysis, obtain the principle of the optimization sequence in the arrival and departure routes, optimize the route gradually, and achieve total optimization of the route network ultimately. Example results show that to ensure the safety and economic efficiency of the route at the same time, the algorithm is not affected by the number of routes, and the operating efficiency is improved significantly.
