This paper describes the full color out-the-window visual system simulator for the Navy's A7E Weapons System Trainer (WST), based on the Vought - developed Computer Animated Photographic Terrain View (CAPTV) concept. The system has excellent scene realism due to its real-world photographic data base. Any geographic area can be ‘flown over' in the simulator with virtually no restrictions on aircraft attitude, position, altitude, heading or velocity. The flyspace can be increased indefinitely by additions to the terrain library. The display field of view is modularly expandable up to nearly the full encircling sphere while maintaining resolution of all parts of the scene.
