The transport aircraft integrated training simulator has the characteristics of complex flight scene, many virtual instruments, large amount of information for man-machine interactive and so on. Setting up virtual simulation environment is vital for the simulator development. This paper introduces the architecture of the integrated training simulator and the development method of the virtual simulation environment. It also uses the method of dynamic interpolation for the whole flight envelope pneumatic parameter to set up quasi-steady six degree of freedom for entire quantity airplane movement model which gives attention to simulation accuracy. It builds the scene model and expounds the frame of visual driver, the development route of virtual instrument and implementation method of man-machine interaction. Testing with the whole system indicates that the simulation system is reasonable and reliable, the mathematic model and simulation algorithm also completely satisfy the system requirements of real-time nature and accuracy, the image display is lifelike.
