Airborne embedded training system is an onboard equipment that can realize scene-oriented combat training anytime and anywhere. Through flight test, its index compliance, design consistency and use effectiveness can be comprehensively evaluated. Firstly, the working mode and system function of embedded training system were analyzed. Secondly, the requirement analysis method of flight test based on three-dimensional structure and the scene design method of flight test oriented to combat mission were put forward. Furthermore, a quantitative index evaluation method based on Sigmoid function and a qualitative index evaluation method based on fuzzy comprehensive evaluation were formed. Finally, based on the actual test flight, the results show that the proposed test design method and evaluation method are feasible and reasonable.
