Ground proximity warning system for use with aircraft having egraded performance |
June 15, 1993 |
| 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 improv |
