Abstract :
This 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 small general aviation 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 pre-processed by proprietary neural network units that feed the 3-D visualization system. The neural network unit is responsible for adaptation of this system and can eliminate problems caused by data delays and data drop-outs. The 3D visualization unit processes data from the neural network unit and eventually from the 6DOF tracker that is placed on the pilot´s Head Mounted Display (HMD). Thbe 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.
