For the automatically controlling an aerodyne for the vertical avoidance of a fixed zone, the method comprises successively: acquiring (21) the limits of the zone to be avoided, modelling the zone by a cylindrical volume (10) delimited by the horizontal contour and the upper and lower altitudes of the zone, locating the volume (10) with respect to the scheduled route (2, 2') of the aerodyne (1), determining (41) the scheduled route (2, 2') entry (Z) and exit (Z') points in the cylindrical volume (10), computing a new flight altitude for the vertical avoidance of the zone (10), and a point for changing altitude (A1, B1) to reach the avoidance altitude, and updating (28) the new flight altitude, and introducing the position of the point for changing altitude (A1, B1) in the automatic pilot.

Pour le pilotage automatique d'un aérodyne pour l'évitement vertical d'une zone fixe, le procédé selon l'invention comprend successivement: l'acquisition (21) des limites de la zone à éviter, et la modélisation de la zone par un volume cylindrique (10) délimité par le contour horizontal et les altitudes supérieures et inférieures de la zone, la localisation du volume (10) par rapport à la route prévue (2, 2') de l'aérodyne (1), la détermination (41) des points d'entrée (Z) et de sortie (Z') de la route prévue (2, 2') dans le volume cylindrique (10), le calcul d'une nouvelle altitude de vol pour l'évitement vertical de la zone (10), et d'un point de changement d'altitude (A1, B1) pour atteindre l'altitude d'évitement, et la mise à jour (28) de la nouvelle altitude de vol, et l'introduction de la position du point de changement d'altitude (A1, B1), dans le dispositif de pilotage automatique.
