Abstract:
1. A method of selecting an aircraft access point into a zone of free lateral deployment, comprising: a computer determining a minimum cost for a selection, by an aircraft, of an access point to a zone of free lateral deployment, using a criterion of minimum cost, wherein the criterion of minimum cost includes a cost of an initial turning maneuver at a start of a joining trajectory leading from a current position of the aircraft to the access point, the aircraft providing information on its current position and its current course, its angle, current roll acceleration and rate, and a location of the aircraft, with respect to its current position, of at least one of relief contours, of threatening on ground obstacles, and forbidden zones, wherein the determining a minimum cost includes: evaluating a situation of the aircraft in its environment, comprising: selecting at least one point of access to a zone of free lateral deployment, comprising: wherein one the determined costs of the initial maneuvers of turning to the right and to the left is the lag required in order for the aircraft to attain a permitted maximum roll angle, to the right for a turn to the right or to the left for a turn to the left.
