A Diversion Path Planning Method of Waypoint Based on Flight Traffic Conduction

Based on flight operation data, this paper constructs a diversion path planning method for busy waypoints by analyzing the relationship of flight traffic conduction between waypoints. Taking busy waypoint KHN as an example, a total of two diversion paths are planned, specifically one in the east-west direction and one in the north-south direction, and the two diversion paths are evaluated in terms of safety and economy, and the results of the evaluations are within the acceptable range. The method of this paper can improve the capacity of airspace resources without changing the existing air route network; at the same time, this method can also assist in identifying the bottleneck of airspace resources, which means identifying the key waypoints affecting the flow of diversion paths, so as to provide certain theoretical references for China to enhance the total number of flights, and to improve the utilization rate of airspace resources and operational efficiency.
