During a take-off or missed approach phase of operation the aircraft\s maximum barometric altitude is retained in a memory element and compared to the aircraft\s current altitude, and if the aircraft\s current barometric altitude should be below the maximum altitude by a predetermined amount based on the aircraft\s radio altitude, a voice warning is generated indicating that the aircraft is descending. Landing gear and flaps are monitored by the system and if the gear or flaps are down, an additional voice warning is generated indicating that the gear or flaps are down.

A ground proximity warning system for use in an aircraft having a plurality of flight configurations for generating a warning of aircraft descent during a take-off phase of flight, comprising: a source of signals representing the flight configuration of the aircraft; logic means, responsive to said configuration signals, for generating a phase of flight signal indicating that the aircraft is in a take-off phase of flight; means for generating a signal indicating that the aircraft is descending; means, responsive to said phase of flight signal and said descent signal, for generating a first warning signal when the aircraft is descending during the take-off phase of flight; and means, responsive to said configuration signals and said first warning signal, for generating a second warning signal when the aircraft is in a first predetermined configuration when the aircraft is descending during the take-off phase of flight.
