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...

Abstract

The invention relates to a method for automatically assisting, by means of data processing equipment onboard said aircraft, an aircraft landing on a runway from a return point (A) to a terminal point (D) where the aircraft makes contact with the runway, the The data processing device is configured to be connected to an altimeter and a deviation gauge, the method comprising: an assisted return navigation phase comprising a position based on the position of the aircraft transmitted by said deviation gauge relative to a connection between said return point (A) and the deviation gauge The measurement of the azimuth deviation from the reference direction (E) to guide the aircraft from the point of return (A) towards the position of the deviation gauge (E), making sure that it is aligned with the point of return (A) and the position of the deviation gauge (E) The position of the aircraft at the predetermined collection point (B), and based on the altitude data provided by the altimeter and the heading and speed data associated with the aircraft, along the predetermined path from the collection point (B) to the predetermined point approximately aligned with the axis of the runway. The standby point (C) guides the aircraft; the assisted landing phase includes guidance from the standby point (C) to the terminal 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 ...
