Vision technologies do more than help pilots see through darkness and land in fog. They show views of the surrounding terrain and alert pilots to obstacles that otherwise could not be seen. Videos from live cameras and up-to-date databases brought into the cockpit and displayed for pilots in a variety of ways are increasing situational awareness and safety on the ground and in the air.
Real-time images are projected onto a head-up display (HUD) screen in front of the pilot, or onto a visor in front of the pilot’s eyes, in the case of head-mounted displays. While enhanced vision systems (EVS) provide a real-time video image of the surrounding terrain, synthetic vision systems (SVS) are generated from a three-dimensional (3-D) map database and a synchronized rendering of the terrain. When these two systems are brought together in a combined vision system (CVS), they provide unprecedented situational awareness in all phases of flight.
Vision technologies are mainly found on busi…
