SYSTEM FOR PREVENTING COLLISION OF AIRCRAFT WITH GROUND Russian patent published in 2006 - IPC G08G5/04 B64D45/04 

FIELD: technology for assuring flight safety by early notification of flight crew of dangerously close ground surface.

SUBSTANCE: system has relief database and module for adaptation to plane type, inputs of which are connected resistor to first and second outputs of block for filling and renewal. Also provided is vertical fly-around block, inputs of which are connected to outputs of relief database, plane type adaptation module, information indicators block and control station. First output of vertical fly-around block is connected to input of warning signals block, and its third output is connected to input of display block. Also, system has local side maneuver map, local map limiter and turn direction block. First input of local side maneuver map is connected to output of relief database, its second input is connected to additional output of vertical fly-around block. Output of local side maneuver block is connected to first input of turn direction block and to first input of local map limiter. Output of the latter is connected to additional input of vertical fly-around block. Second input of turn direction block is connected to second output of vertical fly-around block. Output of turn direction block is connected to additional input of warning signals block and to second input of local map limiter. System makes it possible to determine side turn direction in case of aircraft ground collision danger presence while maintaining flight direction.

EFFECT: improved flight safety.
