Claim 1:
2. The method according to claim 1, wherein the backward search comprises:
exploring, in trajectory sections of a predefined length, paths formed of a sequence of turns and/or straight segments, considering a descent slope, a turn radius and a speed of the aircraft in line with the operational state of the aircraft;
evaluating whether it is safe to implement the holding loop pattern, based on the information about the elevation of the terrain surrounding the runway, by placing the entry point of the STARI procedure on an end of an explored path;
considering the entry point of the STARI procedure to be appropriate when it is safe to implement the holding loop pattern in light of the information about the elevation of the terrain surrounding the runway, and establishing a joining trajectory between said appropriate entry point of the STARI procedure and the entry of the final approach trajectory; and
extending the explored paths with new sections and re-evaluating an implementation of the holding loop pattern when it is not safe to implement the holding loop pattern in light of the information about the elevation of the terrain surrounding the runway.
