A method for laterally avoiding a fixed zone in an aircraft. The contour of the zone to be avoided is modeled by a convex polygon shape. The planned route is located with respect to the modeled zone. The port and starboard sections of the route for exit and return of the planned route are computed.

A method for laterally avoiding a fixed zone in an aircraft. The contour of the zone to be avoided is modeled by a convex polygon shape. The planned route is located with respect to the modeled zone. The port and starboard sections of the route for exit and return of the planned route are computed. A predetermined angle is formed which meets with a corner point of the contour to obtain two avoidance routes formed by the exit and return sections of the route and by the portions of the contour. One of the two avoidance routes is then selected.

[ What is claimed is:] [1.] Method for piloting a vehicle for avoidance of a fixed zone, said fixed zone having at least a portion intersecting an initially planned route, wherein said method comprising the following successive steps:modeling a polygon contour of the fixed zone approximating an actual contour of the fixed zone, said polygon having a succession of segments, with each segment being at least a predetermined length and extending between polygon corner points without bending toward an inner part of the fixed zone;locating the planned route with respect to the polygon contour;determining two avoidance routes as port and starboard side routes leaving the planned route before the fixed zone, with the port side route passing around a left side of the fixed zone and the starboard side route passing around a right side of the fixed zone, and the port side route and the starboard side route returning to the planned route after the fixed zone, each side route including an exit portion extending from an exit point on the planned route to a polygon corner point with each exit point being chosen in order that each exit portion forms a predetermined angle with the planned route at each exit point, a return portion extending from a polygon corner point to a return point on the planned route with each return point being chosen in order that each return portion forms a predetermined angle with the planned route at each return point, and portions of the polygon contour respectively connecting the port and starboard exit and return portions; andselecting one of the port and starboard side routes according to a predetermined criterion.
