What happens if the pilots screw up and try to land a mile before the runway and instead are heading right into a mountain. You're telling me there would be no GPWS warning?!
Advanced GPWS has like 8 modes. The one with the landing gear down, is less sensitive to being close to the ground though. Advanced GPWS uses GPS and a map of terrain + towers to determine what a safe altitude should be according to the configuration of the aircraft..
