ABSTRACT:
Performance of an aircraft ground proximity warning system can be improved, especially where the performance of the aircraft itself has been degraded by a factor such as wind shear, by extending Mode 1 and Mode 3 warning envelopes down to within five feet of the ground. Additional improvements in warnings can be made by monitoring flight path angle, stall margin, angle of attack and deceleration profile, when the aircraft is close to the ground.
