Abstract
The ground proximity warning system and method provide a number of alerts based upon a substantially reduced list of input parameters relative to a conventional ground proximity warning system and method. The ground proximity warning system and method generally constructs alert envelopes and generates alerts if the upcoming terrain or other obstacles pierce the alert envelopes. The ground proximity warning system and method can also generate alerts if the aircraft has an excessive descent rate at a relatively low altitude and if the aircraft descends immediately following takeoff in a similar fashion to Mode and Mode alerts. Further, the ground proximity warning system and method can provide altitude call outs at predefined altitudes above a target runway and can provide alerts if the aircraft appears to be landing short of a runway. The ground proximity warning system and method are capable of providing the various warnings based upon only a pressure altitude, GPS signals and, in some embodiments, the external air temperature. Thus, the ground proximity warning system and method can be independent of a radio altimeter, an ADC, a glideslope receiver and signals indicative of the configuration of the landing gear and flaps.
