The present invention relates to the field of avionics. It relates notably to a method for automatically calculating a trajectory for an aircraft to re-join of a reference route of the aircraft executed iteratively, in particular when the aircraft is no longer locked onto its reference route, each iteration comprising a step of detection of deviation from the active segment of said route; if the deviation from the active segment of said route is detected, the method comprises a step of selection of a route segment to be re-joined, a step of calculation of a re-joining trajectory between a starting point and said route segment to be re-joined, and a step of validation of the trajectory of said route segment to be re-joined. In the case where this trajectory is validated, the method according to the invention comprises a step of assignment of the re-joining trajectory for the segment to the re-joining trajectory for the route. Otherwise, it comprises a step of verification of the existence of a next route segment fulfilling a selection condition. If a next route segment fulfils a selection condition, it comprises a step of selection of said next route segment as route segment to be re-joined, and a return to the step of calculation of a re-joining trajectory for the route segment to be re-joined. If no route segment fulfils the selection condition, it comprises a step of application of an exit procedure. The invention relates also to a system and a computer program for implementing this method. |
