METHOD FOR DETERMINING A GUIDANCE LAW FOR OBSTACLE AVOIDANCE BY AN AIRCRAFT, RELATED COMPUTER PROGRAM PRODUCT, ELECTRONIC SYSTEM AND AIRCRAFT

摘要

This method for determining an obstacle avoidance guidance law for an aircraftisimplemented by a system for determining said guidance law. The aircraftcomprises acollision avoidance system adapted to detect a collision risk with theobstacle and saiddetermination system.This method comprises determining (110) one or more set points from amongflight path angle and speed set points (VZ_consigne, IAS_consigne), at leastone set point(VZ_consigne) depending on at least one vertical speed limit value, at leastone set point(VZ_consigne) comprising a vertical component in a vertical direction, eachlimit valuebeing provided by the collision avoidance system following the detection of acollision riskwith the obstacle(s); and computing (160) the avoidance guidance law as afunction of thedetermined set points.During the determination step, at least one determined set point(IAS_consigne)comprises a longitudinal component in a longitudinal direction perpendicularto the verticaldirection.
