Abstract: To approach the real air war for the air fighter simulator and air combat simulation, the design method that adopts air combat plan to control target plane is presented.The simulation of air combat plan includes both the combat decision simulation and the aircraft simulation.After analyzing the buildup and construction of combat plan, the design concept is put forward that air combat plan can be seen as a series of maneuvers under certain tactics;then its realization method and 4 steps are presented, the problems of multi-aircraft combat plan is discussed;and simulation model is built based on 3-degree-freedom motion equation and basic maneuver library;and the simulation process is expatiated.Finally, the usability is verified through the joint test with the certain flight training simulator.
