METHOD FOR DETERMINING THE HORIZONTAL PROFILE OF A FLIGHT PLAN RESPECTING A VERTICAL FLIGHT PROFILE IMPOSE

摘要

The present invention relates to the definition, in a flight plan, of the horizontal profile of an air route with a vertical profile of flight and speed imposed at the departure and / or arrival, by means of a sequence of waypoints. and / or revolutions associated with local flight constraints and referred to as "D-Fix" because they are not listed in a published navigation database, such as those called "Waypoints". It consists in locating, on curvilinear distance maps, a direct curvilinear path (15) joining the starting point (10) to the destination point (20) of the air route by respecting the vertical flight and speed profiles imposed at the start and / or on arrival and bypassing the surrounding reliefs and respecting restricted overflight zones (3), then approximating the sequence of points of the direct curvilinear path (15) by a chain of straight segments respecting an arbitrary threshold distance from the points of the sequence (15) and an arbitrary threshold of minimum lateral spacing with respect to the set of obstacles to be circumvented (3) and to adopt for points "D-Fix" the points (151 to 154) intermediate junctions of the rectilinear segments.
