Claim Text:
1. A method of determining and forwarding an offset lateral trajectory for an aircraft from an initial lateral trajectory comprising initial waypoints, the method being executed by a flight management system comprising at leak one processor and a storage device storing a navigation database storing waypoints, the offset lateral trajectory rejoining the initial lateral trajectory at first and second junction points, the method comprising: determining the first junction point within the initial lateral trajectory, the first junction point being different from the initial waypoints and from a current position of the aircraft, the first junction point being determined based on: determining, and storing in the navigation database, an offset waypoint for each initial waypoint situated between the first and second junction points; defining a portion of the offset lateral trajectory passing through the offset waypoints, such that the portion of the offset lateral trajectory is the same offset distance from a corresponding portion of the initial lateral trajectory in the predetermined direction; and forwarding the determined offset lateral trajectory from the flight management system to an autopilot system of the aircraft to guide the aircraft along the determined offset lateral trajectory, wherein the first junction point is determined such that:
