摘　　要：航班改航飞行是在空域受危险天气及飞行冲突影响时的一种重要策略。针对初始改航航迹的生成,提出了改进的几何圆切法,用其规划出临时航线,绕过危险区。为避免潜在的飞行冲突,应用几何线性规划法进行了改航策略修正。最后,通过对我国现有航路的仿真分析,表明了算法的有效性。Flight rerouting is an important conflict. Improved tangent to circles arithmetic planning the temporary route and bypassing the gramming was applyed to correct rerouting strat strategy in the airspace with the limit of heavy weather and flight is proposed based on the initial rerouting flight path, which helps dangerous areas. To avoid potential conflicts, geometry linear proegy. Finally, study the existing route with the proposed method. Simulation results show that the algorithm is effective.
