Abstract
Described is a method of protecting an aircraft in approach by signalling against risks of collision with a terrain in steep-sided environments in order to avoid unwanted warnings emanating from clearance sensors of the on-board TAWS (Terrain Awareness and Warning System) while protecting the aircraft when the aircraft fails to observe a published procedure which includes a landing procedure and a take-off procedure. The method, in some embodiments, includes modifying characteristics of at least one of the clearance sensors according to the position deviation of the aircraft relative to a published RNP (Required Navigation Performance) trajectory.
