METHOD FOR SIGNALING SPLASHDOWN AND TAKE-OFF OF AMPHIBIAN AIRCRAFT FROM WATER SURFACE AND DEVICE Russian patent published in 2017 - IPC B64D45/04 G08G5/02 

FIELD: physics.

SUBSTANCE: for signaling splashdown and take-off of the amphibian aircraft, the vibration level and the level of hydrostatic pressure on the hull of the amphibian aircraft boat are measured, the measured values are compared with the threshold values, the landing gear is controlled , the splashdown is decided in excess of the thresholds values, as well provided that the landing gear was not made, otherwise the air location of the amphibian aircraft is decided. The signaling device of the amphibian aircraft splashdown and take-off contains a vibration sensor, a unit of digital signal processing, a hydrostatic pressure sensor, a landing gear sensor. The digital signal processing unit contains a digital bandpass filter, a standard deviation calculator, two threshold devices, "OR"- "AND"- "NOT" circuits, a digital lowpass filter, an expectancy calculator connected in a certain way.

EFFECT: accuracy of determining touch and lift-off points of the amphibian aircraft from the water surface .
