For improving the quality of the exercises, X model remote control simulation aircraft three dimensional flight simulation system is established. The system is based on the computer visualization simulation technology. It is developed using visualization procedure development kit software VB6.0 and application procedure programming interface DirectX. The system has the man-machine interaction function. The moves towards realizing the three dimensional flight simulation system includes importing of 3D models, loading of DirectX and the realization of flying simulation and man-machine interaction. It was shown that the system can lifelike emulate X model remote control simulated aircraft’s operating and control actions, and improve the operator’s fly operate control exercises level when using the simulation system in training.
