A New Algorithm of Flight Rerouting Path Planning in Severe Weather

Abstract

In order to solve the rerouting problem of air traffic management in severe weather areas, a rerouting path planning problem was researched. First, the convex polygon was used to design danger zone. Then, rerouting path planning model was established. After that, a new algorithm used to determine the initial reroute points was proposed. Finally, two examples of the rerouting problem caused by thunderstorms occurring in Southwest China were studied. Compared to the current existing method in real operation, by using this algorithm, the number of reroute points was effectively reduced, and the danger zone was avoided. Additionally, Compared to the geometric algorithm, by using this algorithm, the rerouting path length was reduced by 2.9% and 5% respectively. The results indicate that the algorithm proposed in this paper is effective and practical.
