Patent ID: 7499771

Claim:
A flight management system for aircraft providing a crew of the aircraft with information on diversion airport joining trajectories staggered along the path of the aircraft, said flight management system comprising: a flight management computer for plotting a flight plan on the basis of a trajectory skeleton having a series of waypoints associated with various flight constraints on heading, altitude, speed, introduced by the crew, individually or in subsets, a redirection point database accessible from the aircraft, cataloging associations of waypoints, and of skeletons of trajectories for joining diversion airports starting from said waypoints termed redirection points, and providing links between previous said waypoints and said skeletons of trajectories, and a decision engine activating, when the aircraft passes above or in proximity to the redirection point and under particular flight conditions, a modification of the flight plan followed by the flight management computer for following said trajectory for joining a diversion airport associated with said redirection point, said trajectory being constructed on the basis of the information stored for said redirection point in the redirection point database.
