Producing an airborne digital map database is one of the key technologies that perform flight vehicle low altitude penetration. The method to produce minimal threading surfaces its fitting surfaces and digital maps are studied under the sagety limitation. The motion equations of flight vehicle are transferred to the safety surface, so that terrain and threating factors are introduced to the analysis of vehicle motion. Using minimal principle sets up a performance index of optimization on flight time to terrain avoidance (TF/TA 2). Loading model of terrain database is given, and simulation of loading height database to route planning is completed. The simulation results show that the trajectory is generated by the algorithms can automatically avoid threat and obstacle while it follows terrain.
