An automatic trajectory generation system bringing a flying aircraft from a current position to a destination which: obtains polygons representing obstacles potentially encountered, each polygon associated with an altitude layer; defines two first tangential circles relative to a current direction of the aircraft flight, centered on the right and the left, relative to the aircraft current position; defining two second circles tangential relative to a direction to be followed to destination, centered on the right and the left, relative to the georeferenced destination position; defines a third circle around vertices of the polygons; and searches for a flyable lateral trajectory between the aircraft current position and the destination by bypassing the polygons by the vertices in searching for tangential trajectories between the circles, by observing a pre-established vertical trajectory profile, as well as the lateral margin and a vertical margin with the polygons.

Method and system for calculating the lateral trajectory of an aircraft

To bring an aircraft in flight to a runway, an automatic trajectory generation system obtains a procedure, called STARI procedure, which provides a final trajectory flyable by the aircraft to land on the runway, such that from the entry point of the final trajectory or from any point above it, a holding loop pattern of a predefined shape is flyable in order to dissipate energy if necessary. The automatic trajectory generation system then computes a lateral trajectory, avoiding any terrain relief, meteorological obstacles and military zones, between the current position of the aircraft and the entry point or a point above it, based on performance adapted to an operational state of the aircraft. An overall trajectory is thus obtained, by linking the computed lateral trajectory and the final trajectory of the STARI procedure, including iterations of the holding loop pattern if necessary.
