Abstract
Abstract An airplane route display system for presenting to the airplane passengers, over a television viewing monitor screen, a photographic display of a section of the route viewed by a television camera in the airplane, over which the airplane is being flown. An audio output from a pre-recorded tape describes the scene being viewed by the television camera, with the start of the audio equipment triggered by a remote signal transmitted or reflected from a ground marker serving to synchronize the audio tape. The audio output may also be connected to a microphone for use by aircraft personnel in interjecting a topical comment about the route being displayed.
