Document Type and Number:
WIPO Patent Application WO/2016/107853
Kind Code:
A3
Abstract:
Method for automatically re-joining a route of an aircraft 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 (310) 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 (320) of a route segment to be re-joined, a step of calculation (330) of a re-joining trajectory between a starting point and said route segment to be re-joined, and a step of validation (340) 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 (350) of the re-joining trajectory for the segment to the re-joining trajectory for the route. Otherwise, it comprises a step of verification (360) 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 (370) of said next route segment as route segment to be re-joined, and a return to the step of calculation (330) 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 (380) of an exit procedure. The invention relates also to a system and a computer program for implementing this method.
