The F-4 radar altimeter has a red warning light that lights up when the aircraft goes below a selected altitude. This light is small and will not attract the pilot's attention if it is not in his field of view. Numerous accidents have occurred in which aircraft have struck the ground in level terrain when the mission required primarily straight and level flight. It has been postulated that an aural warning supplied by the radar altimeter would have alerted the aircrew in sufficient time to avoid contact with the ground. (Author)
