Abstract : The patent application relates to a human head trackable wide angle visual system which probes any given terrain constructed on a model board and causes selected image portions thereof to be projected on a trio of display sectors located on the inside surface of a spherical screen, with the view thereof being displayed thereon in accordance with control signals that are respectively portional to the turning of said head about a predetermined axis thereof. A head position sensor, a cockpit, a switching logic circuit, a synchronization signals generator, a trio of video switches, the aforesaid screen, and left, middle, and right light projectors are uniquely combined to provide such effects and, thus, simulate a real-life pilot training environment from a model thereof.
