AIRCRAFT FLIGHT PLAN JOINT ASSISTANCE METHOD BY INTERCEPTING A FLIGHT SEGMENT CLOSE TO THE AIRCRAFT

摘要

The assistance method of an aircraft joined to a flight plan, the flight plan being composed of an N number of flight segments (LEGi, ic [1, N]), the LEGietant flight segment defined by a departure end (WPTi-1) and an end of arrival (WPTi), in a navigation mode called "managed mode", the aircraft having momentarily left the managed mode and having moved away from the flight plan after passing through a waypoint (WPTp, p ⊂ [1, N]), the aircraft occupying a position (PPOS) and seeking to join the flight plan to follow it in managed mode, said method comprising a distance evaluation step of separation (Dj, ic [p + 1, N]) between the position (PPOS) of the aircraft and each of the waypoints (WPTj, ic [p + 1, N]) is characterized in that it comprises the determination of local minimums of the distance between the position (PPOS) of the aircraft and the waypoints (WPTj, ic [p + 1, N]) of the flight plan.
