On flight route planning method of the terrain avoidance system

It is an important step for flight route planning in the process of air terrain avoidance. A reference air route that can guarantee the flight safety, meet flight quality is the basis to accomplish the flying task. This paper research the air route planning for flight terrain avoidance, classify and model to the terrain sampled point by using k mean-value algorithm, and set up the feasible point space. And then using the Dijkstra algorithm to find a high quality air route, based on considering the restrained conditions of flight. Through the simulation, the feasibility and rationality of the scheme was verified.
