Portable helicopter landing area and use method thereof
First Claim
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.

Abstract
The invention relates to a portable helicopter landing area and to the use method thereof. The inventive device comprises two cases (1, 2) which can be carried by the person on the ground (X) and which are intended to be disposed on the selected surface or area (H). Moreover, two units (A, B) can be removed from the aforementioned two cases respectively. The visual positioning unit (A) comprises: a light which produces four successive white flashes (7) and which is visible from a distance of at least forty kilometers by an aircraft pilot, and a high-frequency current generator unit. The lighting unit (B) comprises: (i) at least five marker lights (16a to 16e) which are disposed in the form of a Y on the ground, thereby creating five white points on the ground which turn blue when the pilot reaches the vertical above the selected landing area or surface (H); and (ii) a kit for the assembly of an illuminated wind cone which provides information relating to the wind at the aforementioned selected landing area or surface (H). The invention is suitable for emergency operations requiring the intervention of at least one airborne team and, in particular, a heliborne team.
