Abstract:
1. A method for locating and beaconing any chosen touchdown surface or area (H) for an intervention at night or in bad weather of at least one airborne team carrying out one or more rescue operations, cooperating with at least one person intervening on the ground (x) positioned on said chosen touchdown surface or area (H), so as to allow the fast and safe landing or takeoff of of aircraft including helicopters, transporting airborne team or teams, characterized in that it allows said airborne team, after deployment, setup and lighting of an item of hardware by said at least one person intervening on the ground (x), to pinpoint locate, approach and overfly any chosen touchdown surface or area (H), by visual location and beaconing formed of at least five independent and energy-autonomous beacons, so as to cause a visible luminous change from the aircraft with the aid of the beaconing which emits skyward a substantially horizontal beam of light of a first color and a central beam of vertically concentrated a light of different color, only the central beam being perceived by the passage of the aircraft vertically above this beaconing, so as to land to take off again in almost complete reliability on the touchdown area.
