Enhanced Vision System

An Evs Increases Situational Awareness Using Tiny, Lightweight Sensors That Can See Through Most Weather and Lighting Conditions

If you’ve flown in reduced visibility or on a clear, moonless night and wondered what was ahead, you’re not alone. Pilots flying aircraft equipped with an enhanced vision system receive increased situational awareness information delivered to the cockpit in limited-visibility situations both day and night.

Manufacturers such as Max-Viz, Kollsman and Rockwell Collins produce infrared sensors like those in forward-looking infrared (FLIR) cameras used by the military and law enforcement.

EVS infrared cameras detect the heat of objects to create a Black and-white image of the world ahead, whether it’s a person standing on the ramp, mountains to either side of the approach path or lights on the active runway .
