On the other hand, the operation of the aircraft maintenance support VR training subsystem is sent to the virtual simulation central processing unit through the external network, and the simulation subsystems connected to the platform also perform simulation solutions according to the input, and then the solution results are fed back to the semi-physical simulation cockpit and the aircraft maintenance support VR training subsystem respectively. The instructor can monitor and control the entire training process through the training control and management system software of the training console. The trainees' operations in the simulated cockpit can be synchronously displayed on the training console, and the instructor can intervene and provide guidance based on the training situation.
