METHOD FOR DISPLAYING INFORMATION ON VERTICAL DISPLACEMENT OF SHIPBORNE LANDING STRIP WHEN LANDING HELICOPTER ON SHIP Russian patent published in 2017 - IPC B64F1/18 B64D45/04 B64D47/06 

FIELD: physics.

SUBSTANCE: invention relates to a method for displaying information on vertical displacement of shipborne landing strip (LS) when landing a helicopter on a ship. In order to display the information, a multifunctional indicator of LS vertical movement is set vertically on the superstructure of the ship in the direction of the helicopter landing approach, heaving motion of the LS center is displayed using super-bright LEDs located parallel to the long side of the indicator in the form of a colourless bar chart. Its beginning is a group of LEDs of the same colour, indicating the beginning of the movement of the LS center, and its end is a group of LEDs of a different colour, which indicates the predicted completion of the LS movement. The amplitude of the colourless bar chart is proportional to the movement time of the LS center from top to bottom or from bottom to top. The indication symbol of the LS position, safe for helicopter approach is displayed by a group of LEDs of the third colour.

EFFECT: safety of helicopter landing on the ship in difficult weather conditions and at different times of the day.
