Abstract
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.
