METHOD AND SYSTEM FOR PREVENTION OF AIRCRAFT COLLISION WITH TERRAIN RELIEF Russian patent published in 2009 - IPC G08G5/04 

FIELD: instrument making.

SUBSTANCE: group of inventions is related to equipment for measurement, alarm and control for wide class of airplanes, helicopters, unmanned aircrafts, in particular, agile aircrafts. In suggested method they define parametres of aircraft position and motion, calculate altitude loss after connection of automatic creeping, on its basis they calculate altitude for connection of automatic creeping, and automatic creeping off land is carried out with descent of aircraft down to altitude of automatic creeping connection. Maximum height of terrain relief is defined in zone of terrain relief monitoring zone, relative to which they calculate altitude of automatic creeping connection. Trajectory of automatic creeping is formed depending on extent of broken terrain relief in this zone. Suggested system comprises metre of absolute barometric altitude of flight, navigation system, control calculator, facilities for memorising and processing of terrain relief data, autopilot. Facilities for memorising and processing of terrain relief data are realised with the possibility to detect maximum and minimum heights of terrain relief in zone of terrain relief monitoring. Control calculator is arranged with the possibility to calculate altitude to connect automatic creeping off land with account of maximum height of terrain relief in zone of terrain relief monitoring, calculation of broken terrain relief index in this zone and generation of automatic creeping trajectory depending on index of broken terrain relief.

EFFECT: higher safety of flight near land.
