In order to improve the development of safety behavior of flight cadets and enhance the level of flight training, conduct an indepth exploration of the relationship and intrinsic mechanism between authentic leadership style and safety behavior of flight cadets, a theoretical model of the safety behavior of flight cadets based on the authentic leadership style theory was constructed. The questionnaire was developed by drawing on established scales and consulting experts to align it with the current training conditions of aviation schools. AMOS26.0 software was used to test the mediating effect of authentic follow and the moderating effect of basic psychological needs satisfaction, and verify the effect on all constructs, the applicability of the theoretical model of flight cadets safety behavior in different stages of learning to fly, flight level, instructor job groups and work environment. The results show that there is a positive correlation between the authentic leadership style of flight instructors and the safety behavior of flight cadets, and the authentic follow of flight cadets plays a mediating role between the two. The authentic leadership style has a positive impact on authentic follower, and the basic psychological needs satisfaction plays a moderating role in this process. Different groups between the four dimensions of stages of learning to fly, flight level, instructor job groups and work environment have no moderating effect on the model, further verifying the structural stability of the model.
