In order to adequately verify the equipment performance, discriminate the equipment design defects as early as possible, accelerate the development of equipment, provide more useful test results for army combat training, the design of the flight test for military avionics/weapon systems based on operational use was proposed in this paper. A tree-type test structure was constructed through combat mission analysis, and the design of realistic operational test environment was pointed out. The purpose of this paper is to provide more meaningful result data by carrying out task oriented flight test.
