摘要:
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.

The invention relates to an aircraft navigational aid system with 3D display including an anti-collision device, with means of storing data representing obstructions, means for calculating a representation of the obstructions in a three-dimensional space and a device for displaying the obstructions data in three dimensions. The system includes means for augmenting the display of the representation of the area of hazardous obstructions with at least two indicator objects for the said area of hazardous obstructions disposed together in such a manner as to form a third object targeting the localization of the point in the area of hazardous obstructions closest to the aircraft. The invention also relates to the method of display of the indicator objects in a three-dimensional display.

The present invention relates to the definition, in a flight plan, of the horizontal profile of an air route with vertical flight and speed profile prescribed on departure and/or on arrival, by a stringing together of check-points and/or turn points associated with local flight constraints and called “D-Fix” because they are not listed in a published navigation database like those called “Waypoints”. It consists in charting, on curvilinear distance maps, a direct curvilinear path joining the departure point to the destination point of the air route while complying with vertical flight and speed profiles prescribed on departure and/or on arrival and while guaranteeing a circumnavigation of the surrounding reliefs and compliance with regulated overfly zones, then in approximating the series of points of the direct curvilinear path by a sequence of straight segments complying with an arbitrary maximum deviation threshold relative to the points of the series and an arbitrary minimum lateral deviation threshold relative to the set of obstacles to be circumnavigated and in adopting as “D-Fix” points the points of the intermediate intersections of the rectilinear segments.

A method and device checks the conformity of a trajectory calculated by a flight management system of an aircraft in relation to reference data comprising a reference map. The method includes: geo-referencing of a reference map; determination of a reference trajectory from the geo-referenced reference map; detection of nonconformity in the trajectory calculated by the flight management system by comparison of the trajectory calculated by the flight management system with the reference trajectory; and emission of a warning if a nonconformity is detected.
