METHOD FOR PREVENTION OF THREAT OF AIRCRAFT COLLISION WITH OBSTACLES OF UNDERLYING SURFACE Russian patent published in 2009 - IPC G08G5/00 

FIELD: physics, measurement.

SUBSTANCE: invention is related to the field of aviation engineering, namely to on-board systems of prevention of collision with ground. Method consists in preliminary creation of data base of underlying surface relief, aeronavigation data base, data base of aircraft (AC) performance characteristics. Borders of attention zone and control zone (CZ) are calculated, obstacle of highest threat in CZ is separated, which is located in zone of calculated trajectory prediction. Taking into account data on limitations of AC motion parametres and external effects, parametres of nominal flight are calculated, which provide for obstacle overflight at height close to minimum permissible height. Control signals are generated according to selected control law and with account of environment factors effect, which are sent to actuators of flight control and engine thrusts, and are also displayed on screen of flight director.

EFFECT: expansion of resources of existing systems for prevention of collision with ground obstacles and reduction of collision risk under effect of wind disturbances and under effect of human factor.
