Abstract
A system for automatically modifying a lateral flight plan of an aircraft includes modifying means adapted to modify the flight plan by an action to chosen among the following actions: deleting, adding and moving at least one waypoint of an initial flight plan (T1). The modified flight plan (T3) includes one downstream waypoint (P6) defined as the waypoint on which the aircraft gets back to the initial flight plan (T1), and one upstream waypoint (P4) preceding the downstream waypoint (P6). By defining an intermediate point (P5′) between the upstream (P4) and downstream (P6) waypoints, the coordinates are calculated in order to allow the aircraft to reach the downstream waypoint (P6) with the same course as the initial flight plan (T1).
