Method and avionics computer for adapting an anchor point of a terminal segment with respect to a landing threshold point, for a non-precision approach

A method for adapting an anchor point of a terminal segment of a virtual path for a non-precision Flight Management System (FMS) Landing System (FLS) approach mode of an aircraft, with a view to landing the aircraft on a runway of an aerodrome, the method being implemented in an avionics computer comprising at least a processing unit and a navigation database,

• wherein the method comprising at least the following steps, implemented by the processing unit of the avionics computer:
• comparing a distance between a first position and a second position with a predetermined distance, the first position corresponding to a position of an initial anchor point of an initial terminal segment and the second position corresponding to the position of a landing threshold point of the runway;
• checking whether the direction of the terminal segment of the virtual path crosses the landing threshold point of the runway;
• computing the landing threshold point of the runway as an anchor point if the distance between the first position and the second position is less than the predetermined distance and if the initial terminal segment of the virtual path crosses the landing threshold of the runway;
• and
• executing the FLS approach to land the aircraft on the runway at the anchor point.
