SYSTEM "AUTOMATIC LIGHT POSITION INDICATOR OF DECK DURING ROLLING" Russian patent published in 2019 - IPC B64F1/18 

FIELD: lighting engineering.

SUBSTANCE: invention relates to marine light-signaling devices and is intended for informing a helicopter crew about critical angles of a slope of a site and direction of its vertical movement during landing on a stern and nose air strip or take-off from it by means of visual signaling. System comprises four light sources arranged horizontally and vertically and indicating permissible and critical transverse angle and longitudinal angle of slope of air strip respectively, two light sources arranged in upper and lower parts of "cross" and indicating direction of vertical movement of landing strip up and down respectively, interfacing unit, programmable logic controller of control device, position sensor, an operator panel, an uninterrupted power supply built into the control device.

EFFECT: higher safety of helicopter landing or take-off due to increase in information value of indicators, ease of reading information by pilot, quick operation of system, with its independence and low power consumption.
