Embodiment Construction
[0061] Such as figure 1 As shown, one embodiment of the invention relates to a method for automatically assisting an aircraft 1 to land on a runway from a return point A until an end point D, at which point the aircraft makes contact with the runway.
[0062] This method is passed as figure 2 The data processing device 2 of the assisted landing system 3 shown is implemented. The assisted landing system 3 may also comprise an altimeter 4 onboard the aircraft, to which data processing equipment may be connected.
[0063] refer to figure 1 , you can also define the following points:
[0064] - Return point A: at this point the aircraft is detected by the assisted landing system 3 . It should be noted that, in the present invention, the point is defined as the position (altitude, distance, etc.) of the unknown aircraft;
[0065] - Acquisition point B: at this point the aircraft enters the phase of alignment with the landing runway;
[0066] - Standby point C: the point alig...

The present invention relates to a method for automatically assisting with the landing of an aircraft on a runway from a return point (A) to a completion point (D), at which the aircraft touches the runway, by means of a data-processing device on-board said aircraft, which device is configured to be connected to an altimeter and a deviation meter, the method including: a return-navigation assistance phase including guidance of the aircraft, on the basis of measurements of the azimuth deviation of the aircraft relative to a reference direction linking said return point (A) and the position of the deviation meter (E) transmitted by said deviation meter, from the return point (A) towards the position of the deviation meter (E), determination of the position of the aircraft at a predeterminedcapture point (B) that is aligned with the return point (A) and the position of the deviation meter (E), and guidance of the aircraft along a predetermined path from the capture point (B) to a predetermined holding point (C), which is approximately aligned with the axis of the runway, on the basis of altitude data provided by the altimeter and heading and speed data relating to the aircraft, a landing assistance phase including guidance from the holding point (C) to the completion point (D).
Description
technical field [0001] The invention relates to the field of aircraft guidance. [0002] The subject of the invention is more particularly a method for automatically guiding an aircraft, such as an unmanned aircraft, from a position remote from an airport until the aircraft lands on a runway. Background technique [0003] Existing drone guidance systems enable the automatic guidance of the drone along predetermined trajectories, for example corresponding to the path of the observation mission. In order to obtain such guidance, the position of the aircraft is determined at regular time intervals and compared with the trajectory to be followed. This position is typically determined using a receiver of an absolute positioning system by satellite, such as GPS or the Galileo system, known as the GNSS system ("Global Navigation Satellite System"). [0004] However, it may happen that the aircraft's computer is unable to determine the aircraft's current position due to a failure ...
