ABSTRACT:
A ground proximity warning system monitors the descent rate of an aircraft and generates a warning if the descent rate is excessive for the current altitude above ground of the aircraft according to a predetermined relationship. The predetermined relationship is altered as a function of the deviation of the aircraft from the glidescope to generate the warning earlier if the aircraft is below the glidescope and later if the aircraft is above the glidescope. The warning is given as a specific aural message indicating the specific flight parameters of the aircraft.
