AIRCRAFT AND SIGNALLING SYSTEM OF AN UNPREPARED LANDING AREA

A method of assisting piloting, which method comprises the steps of designating a landing point and determining a sighting axis. A single three-dimensional main symbol providing a conformal position of the landing point is displayed on the screen so long as it is present in a field of view along the sighting axis, the three-dimensional main symbol extending in elevation upwards from the ground from a bottom zone positioned on the ground up to a top zone positioned at a top height relative to the ground. At least while the aircraft is situated at a distance from the landing point that is less than a first threshold distance, at least one two-dimensional main symbol covering a target zone is displayed.
