ABSTRACT:
A ground proximity warning system (GPWS) for a rotary-wing aircraft provides a warning of excessive barometric altitude loss as a function of the product of time and the terrain clearance. The warning system is only enabled during a take-off mode of flight and is disabled during other modes of flight. The mode warning logic monitors the speed of the aircraft, the terrain clearance of the aircraft as well as the position of the landing gear to enable the altitude loss warning logic. When the barometric altitude loss as a function of the time product of the terrain clearance exceeds a predetermined value, the mode switching logic switches to an approach mode of flight to disable the excessive altitude loss warning system to minimize nuisance warnings during various maneuvers including ship-to-ship and oil platform-to-oil platform flight maneuvers.
