Looking around at visuals

For both civil and military transport aircraft, the WIDE visual image representation system for flight simulators makes image data available over the full display width of 150 deg in azimuth, though at the expense of display resolution and scene brightness. The follow-on WIDE I system uses three TV projectors to produce an image on a curved screen above the simulator cockpit, which is then seen by the crew through a curved collimating mirror in front of the cockpit windows. A further development, WIDE II, increases the number of projectors to five. The IMAGE III System, which uses separate microprocessors for the generation of surfaces, light points, moving coordinates, etc, can furnish radar simulation and weapon effects.
