Patent ID: 8612070

Claim:
A device for aiding the deck-landing of a pilotless rotary-wing aircraft on a mobile station, called a ship, the aircraft being intended to be controlled remotely on the basis of said device, comprising: means for receiving data from the aircraft, comprising attitudes of the aircraft and a computer, the aircraft hovering ready to land on deck, the deck-landing decision having to be made under certain conditions comprising a first set of predictive criteria and a second set of non-predictive criteria, the predictive criteria corresponding to parameters measured by the computer and whose value may be extrapolated in the near future, the predictive criteria relating to the attitudes of the aircraft and of the ship, amplitude and speed of the swell, a strength and direction of wind on the deck of the ship, the non-predictive criteria corresponding to parameters not measurable by the computer, the non-predictive criteria relating to the clearance of the deck, wherein the computer makes it possible to deliver at least one temporal indicator indicating that the predictive criteria are favourable or unfavourable to a deck-landing, and a display making it possible to represent the indicator in a first state when the predictive criteria are favourable to deck-landing.
