Multipurpose Visualization System

This paper deals with the design and architecture of the low cost multipurpose flight visualization system (MFVS). The MFVS system was originally developed as a passive IFR approach system for general aviation small planes. A relatively high adaptability is one of the main advantages. It can be easily used with many types of avionics devices. The GPS/INS system is used as the primary data source. The data from the GPS/INS system are preprocessed by proprietary neural network unit that feeds the 3D visualization system. The neural network unit is responsible for adaptation of this system and can eliminate problems caused by data delays and data dropouts. The 3D visualization unit processes data from the neural network unit and eventually from the 6DOF tracker that is placed on the pilot´s HMD (head mounted display). The unit then generates a 3D view of the surrounding environment that is similar to the 3D environment the pilot knows from flight simulators. The source of environment data is the terrain and object/obstacle database. The image output can be displayed on HUD, MFD or HMD
