Abstract
The present invention relates to a method of protecting an aircraft in approach by signalling against the risks of collision with the terrain in steep-sided environments, in order to avoid unwanted warnings emanating from the clearance sensors of the onboard TAWS system while protecting the aircraft when it fails to observe the published procedure, and this equally in a landing procedure and in a take-off procedure, and it is characterized in that it consists in modifying the characteristics of the clearance sensors according to the position deviation of the aircraft relative to the imposed RNP trajectory.
Claims15
A method of protecting an aircraft by signalling against the risks of collision with the terrain in a constrained environment consisting, when the aircraft follows an RNP procedure, in adjusting the characteristics of at least one clearance sensor of an onboard TAWS system for automatically signalling risks of collision with the terrain to the characteristics of the imposed RNP trajectory as defined in an onboard database in the aircraft.
A device for protecting by signalling against the risks of collision with the terrain in the approach of an aircraft in steep-sided environments, in order to avoid unnecessary warnings emanating from the clearance sensors of the onboard TAWS system for automatically signalling risks of collision with the terrain, comprising a conventional TAWS system for which the characteristics of the clearance sensors are adjusted locally, a device for determining entry into RNP mode, an RNP database DB and a terrain database.
