Research on instrument approach segment path planning under Thunderstorm weather

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, this theory adopt advanced dynamic window algorithm (DWA) 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 artificially set for simulation to verify the functionality of the algorithm to avoid thunderstorm diversion simulation. Then, by fitting the thunderstorm displacement coordinates in the case with time correlation, the thunderstorm predicted movement trajectory is obtained and brought into the algorithm for simulation. Finally, analyse the cosine similarity, economy and practicability of the actual and simulation diversion track. 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 has strong practicability.
