| 1. 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.
