The configuration and characteristics of the flight management and control system of an UAV is quite different from that of manned aircraft. A visual flight simulation is a most important way to improve the performance and effectiveness of UAVs in practical field use. In this paper, a visual flight real time simulation environment (RTSE) for UAVs is programmed in Java combined with the Virtual Reality Modeling Language (VRML) and C++ language. The advantages of Java in this project are introduced. Its disadvantages are overcome through a three layer program. The bottom layer is the device-driven system layer with hardware access capability programmed in C language. The middle layer is the dynamical link library that is made up of the native methods of Java application programmed in C++ language. The top layer is the application program programmed in Java language and VRML. The RTSE has the ability to provide significant training, demonstration and assessment of the UAVs economically, and reduce the operator workload.
