METHOD AND DEVICE FOR WATER LANDING OF HYDROPLANE Russian patent published in 1999 - IPC

FIELD: light warning devices for flight-operations support; light warning devices for seadromes. SUBSTANCE: marked section of water area is illuminated by light flux from landing light of hydroplane reflected from passive light-return film coats located on anchorless streamlined floats-markers interconnected in one line and secured to anchor at one or held by boat. Floats are self-oriented in wind or in wave. At illumination by landing light of hydroplane, device furnished information on deviation of hydroplane from altitude limiting line (glide path) through matching white and red horizon light by maneuvering hydroplane in altitude. Direction of landing in horizontal plane is secured by identification of position of hydroplane relative to line of interconnected anchorless markers; levelling, touch-down on water surface and braking-by markers (respectively) RUNWAY BEGINNING, TOUCH-DOWN POINT and RUNWAY END. EFFECT: enhanced efficiency and reliability. 3 cl, 6 dwg
