METHOD FOR GENERATING A HORIZONTAL PATH AVOIDING DANGEROUS ZONES FOR AN AIRCRAFT

A method for generating a horizontal path for the avoidance of danger zones for an aircraft. The method models the contours of each danger zone by a succession of segments demarcated by points. The method determines two homing circles and two capture circles passing respectively through the initial point and final point which are tangential respectively to the initial route and to the final route and have respectively the initial and final turning radius. The method also determines tangents both to the homing circles or the capture circles and to the contour of each danger zone. Among these tangents, a pair of tangents to a homing circle and to a capture circle are selected, defining a path skeleton connecting a homing circle to a capture circle without meeting a danger zone. And, an automatically controllable evasion path that lies on the previously defined path skeleton is then determined.
