Claim Text:
1. A method for assisting in the piloting of an aircraft during a landing on a landing area on the ground, this aircraft comprising at least one display screen in its cockpit as well as human-machine interface associated with this screen, comprising the following steps: A) during a phase corresponding to this landing, during which said landing area on the ground is visible from the aircraft: A1) calculating an initial target and an initial axis of taxiing trajectory by a dialogue device and displaying, on said screen, the initial target corresponding to this landing, overlaid on a view outside the aircraft, said view comprising a view of at least a part of the landing area on the ground wherein: the initial target is automatically displayed on the screen based on a point on the ground, the initial axis of taxiing trajectory on the ground, and a slope of an axis of approach; and the initial axis of taxiing trajectory is automatically displayed on the screen from the target; A2) receiving commands to modify the initial target and to modify the initial axis of taxiing trajectory by a pilot of the aircraft, using a human-machine interface associated with this screen and displaying the duly modified target and modified axis of taxiing trajectory on this screen in response to the modify commands; A3) receiving a command to validate a value of the modified target by a pilot of the aircraft, using the human-machine interface associated with this screen wherein the value of the modified target includes positional coordinates of the target with respect to the aircraft such that the positional coordinates are based on a heading angle, an azimuth angle and at least one of: a distance between the aircraft and the target; and a relative height of the aircraft in relation to the target; B) automatically determining a flight trajectory of the aircraft as a function of at least the relative position of the aircraft in relation to the value of the modified target validated by the pilot in the step A3) and storing this trajectory; C) guiding the aircraft based on the displayed flight trajectory of the aircraft.
