DEVICE FOR PREVENTION OF AIRCRAFT ROLLING-OFF BEYOND RUNWAY Russian patent published in 2015 - IPC B64D45/00 B64D45/06 

FIELD: aircraft engineering.

SUBSTANCE: device comprises navigation system, signalling system, data base containing data on takeoff and landing, computer, unit for communication with onboard hardware, thrust reverse control leer interlock mechanism control unit and unit for communication with thrust control ACS. Computer incorporates current negative acceleration and turn-off range computation unit with input connected via communication unit with onboard hardware. Computer additionally incorporates engine thrust reverse control lever interlock deactivator. Reverse input is connected with current negative acceleration and turn-off range computation unit output to current speeds and accelerations. Reverse output is connected with control input of the switch connected by its input with output of the unit computing the actual distance to runway end to comparison with required tear-off range. Switch output is connected with signalling system inputs, those of engine thrust reverse control lever interlock mechanism and unit for communication with thrust control ACS.

EFFECT: higher reliability of engines.
