Piloting assistance method for facilitating landing an aircraft on a landing zone, the method comprising a selection step for selecting said landing zone on which said aircraft has to land, characterised in that said method comprises the following steps: - activating a guiding mode of an automatic piloting system in order to automatically guide the aircraft towards the landing zone during an approach, - capturing an image stream of the landing zone by means of a video acquisition system comprising at least one camera, and transmitting said image stream to a first imaging system and to a second imaging system, said image stream comprising a real image of the landing zone at a current calculation time, - calculating position information of the landing zone on the basis of at least said real image by means of the first imaging system, said position information defining a relative position of the landing zone with respect to the aircraft, and transmitting said position information to the automatic piloting system, - determining, by means of the automatic piloting system: ∘ a current position of the landing zone at the current calculation time by feeding said position information into a Kalman filter estimator, ∘ a target position of the landing zone which will be reached by the landing zone when the aircraft lands on said landing zone, which position is determined by means of said estimator, ∘ a consolidated path leading towards the target position of the landing zone depending on at least one stored approach model, - transmitting at least the current position and the consolidated path to the second imaging system, - verifying, by means of the second imaging system, that a landing zone is present at said current position in said real image, - generating an alarm if said presence is not verified, - displaying the real image and a first symbol positioned at said current position on a first display for visual comparison by a pilot. - activating a guiding mode of an automatic piloting system in order to automatically guide the aircraft towards the landing zone during an approach, - capturing an image stream of the landing zone by means of a video acquisition system comprising at least one camera, and transmitting said image stream to a first imaging system and to a second imaging system, said image stream comprising a real image of the landing zone at a current calculation time, - calculating position information of the landing zone on the basis of at least said real image by means of the first imaging system, said position information defining a relative position of the landing zone with respect to the aircraft, and transmitting said position information to the automatic piloting system, - determining, by means of the automatic piloting system: ∘ a current position of the landing zone at the current calculation time by feeding said position information into a Kalman filter estimator, ∘ a target position of the landing zone which will be reached by the landing zone when the aircraft lands on said landing zone, which position is determined by means of said estimator, ∘ a consolidated path leading towards the target position of the landing zone depending on at least one stored approach model, ∘ a current position of the landing zone at the current calculation time by feeding said position information into a Kalman filter estimator, ∘ a target position of the landing zone which will be reached by the landing zone when the aircraft lands on said landing zone, which position is determined by means of said estimator, ∘ a consolidated path leading towards the target position of the landing zone depending on at least one stored approach model, - transmitting at least the current position and the consolidated path to the second imaging system, - verifying, by means of the second imaging system, that a landing zone is present at said current position in said real image, - generating an alarm if said presence is not verified, - displaying the real image and a first symbol positioned at said current position on a first display for visual comparison by a pilot.
