Enhanced flight vision system

An Enhanced flight vision system (EFVS, sometimes EVS) is a system for imaging the external world from an aircraft, and to provide an image in which objects can be better detected. In other words, an EFVS is a system to provide and image which is better than unaided human vision. An EFVS includes sensors (one or many) such as a color camera, infrared camera or radar, and typically a display for the pilot, which can be a head-up display or head-down display. An EFVS may be combined with a synthetic vision system to create a combined vision system. ^[1]
