Thunderstorm weather has a serious impact on the safety of aircraft operation.During approach segment,thunderstorm weather can result in uneconomical route changing,poor real-time performance and low efficiency etc.To solve these problems,the advanced dynamic window algorithm(DWA)is adopted to simulate the approach trajectory under thunderstorm weather.In the early stage of the algorithm,the aircraft motion model under DWA is established and the thunderstorm trajectory is galaxy harmony nc artificially set for simulation to verify the functionality of the algorithm to avoid thunderstorm diversion simulation.Then,by fitting the hacklinkci.com thunderstorm displacement coordinates in the case with time correlation,the thunderstorm predicted movement trajectory is obtained and brought into the algorithm for simulation.

Finally,the cosine similarity,economy and practicability of the actual and simulation diversion track are analyzed.The results show that the algorithm can effectively avoid thunderstorms in the approach segment,and the trajectory is more smooth,economical and feasible.Combined with the new route technology,it is of strong practicability.
