Method and a device for marking the ground for an aircraft in flight, and an aircraft including the device
First Claim
1. A method of marking a landing zone on the ground for an aircraft in flight, the landing zone being targeted by the aircraft flying at a height lying between a predefined maximum height and a predefined minimum height, in which method the aircraft uses a projector on-board the aircraft to project on the ground a projected light shape having at least one line of light defining a geometrical surface, the aircraft tending to place at least a portion of landing gear of the aircraft on the geometrical surface, the projected light shape being identical regardless of the position of the projector in air space.

Abstract
A method of marking a landing zone on ground for an aircraft in flight. The aircraft projects on the ground a light shape referred to as a “projected light shape” comprising at least one line of light defining a geometrical surface, the aircraft tending to place at least a portion of landing gear of the aircraft on the geometrical surface, the projected light shape being identical regardless of the position of the projector in air space.
