Ground proximity warning system (GPWS) is a system designed to alert pilots if their aircraft is in immediate danger of flying into the ground or an obstacle. The United States Federal Aviation Administration (FAA) defines GPWS as a type of terrain awareness warning system (TAWS).[1] More advanced systems, introduced in 1996,[2] are known as enhanced ground proximity warning systems (EGPWS), although sometimes called terrain awareness warning systems.
