Charles D Bateman, Michael M Grove, Lyle J Noland, Wallace E Ward: Position based ground proximity warning system for aircraft. Sundstrand Data Control, Mason Kolehmainen Rathburn & Wyss, January 28, 1986: US04567483 (44 worldwide citation)

In order to reduce nuisance warnings and to increase the effectiveness of real warnings produced by a ground proximity warning system, the criteria for generating a warning is varied for certain airport areas to take into account the terrain in those areas. Along with position data, certain flight p ...

Charles D Bateman, Michael M Grove: Ground proximity approach warning system without landing flap input. Sundstrand Data Control, Mason Kolehmainen Rathburn & Wyss, April 3, 1990: US04914436 (42 worldwide citation)

A ground proximity warning system is disclosed which can recognize when an aircraft is on a final approach to an airport without utilizing a landing flap signal input. Airports together with the surrounding terrain topography are modeled by a simple geometric shape, such as, an inverted truncated co ...

Charles D Bateman, J H Glover, Hans R Muller: Ground proximity warning system for use with aircraft having egraded performance. Sundstrand Corporation, Fitch Even Tabin & Flannery, June 15, 1993: US05220322 (35 worldwide citation)

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 wa ...

Charles D Bateman, Hans Rudolf Muller: Aircraft ground proximity warning system having speed versus altitude compensation. Sundstrand Data Control, Ted E Killingsworth, Michael B McMurry, March 16, 1976: US03944968 (25 worldwide citation)

The warning system includes a function generator for generating a signal representative of a minimum altitude over terrain as a function of the aircraft's speed. This signal is combined with a signal representing the aircraft's actual altitude over the terrain and if the aircraft is below this minim ...
