Planning of arrival and departure routes in terminal maneuvering area based on high dimensionality reduction environment modeling method

Abstract

The efficient design of arrival and departure routes in the terminal maneuvering area plays a key role in increasing airport capacity and reducing traffic congestion. In our study, we establish an arrival and departure route planning model in the terminal maneuvering area, taking into account the airspace environmental constraints and aircraft operational constraints. Then the three-dimensional environment modeling method with a high degree of dimensionality reduction is introduced to improve the efficiency of route planning, and routes are planned sequentially using the A* algorithm in a dimensionally reduced environment. Numerical simulation tests, performed on the terminal maneuvering area of Chengdu Shuangliu Airport in China, show the effectiveness of the proposed method. Each route is given two planning schemes considering the maximum and minimum takeoff or descent slope, and a total of seven routes is generated.
