In order to set up the virtual air simulation, and realize the correctness of complex air-attacking action simulation, the paper designs the typical flight target track model and performs the simulating of flight. Analyzing moving track and characteristics of flight target, seven kinds of typical and universal scenario design method and mathematical model are given to describe flight track of moving target. At the same time, analyses the process flow of flight track simulation, and provide resolve method of several key technique for flight track simulation. Practice proves that the model and method show correct and good effect in Simulation application
