A method of automatically controlling an aircraft to avoid a vertical zone includes several steps. The aircraft first acquires limits of the zone to be avoided. The zone is modeled by a cylindrical volume which is limited by a horizontal contour with upper and lower altitudes of the zone. The cylindrical volume associated with a scheduled route of the aircraft is located and points of entry and exit in the cylindrical volume are determined. A new flight altitude is calculated in order to avoid the zone. A point of change of altitude is calculated to reach an avoidance altitude. The new flight altitude is updated and the point of change of altitude is input into an automatic pilot.

[ What is claimed is:] [1.] Method for automatically controlling an aerodyne for vertical avoidance of a zone to be avoided with predefined geometrical contours, said aerodyne being equipped with an automatic piloting device, into which have been input a scheduled route and a vertical trajectory profile including a cruising flight altitude and a position of a point of descent towards a scheduled runway, said method comprising the following steps in succession:acquiring limits of the zone to be avoided in a form of a horizontal contour with upper and lower altitudes,modelling of the zone to be avoided by a cylindrical volume delimited by the horizontal contour with the upper and lower altitudes,locating the cylindrical volume with respect to the scheduled route of the aerodyne so as to determine whether this route traverses the cylindrical volume,determining points of entry and of exit of the scheduled route in the cylindrical volume, if the scheduled route traverses the cylindrical volume,calculating optimum and maximum altitudes capable of being reached by the aerodyne, and current weight of the aerodyne when passing through the point of entry, account being taken of the current weight of the aerodyne and of consumption of fuel in order to reach this point of entry,calculating a new flight altitude for the vertical avoidance of the cylindrical volume, and of a point of change of altitude so as to reach an avoidance altitude, as a function of the lower and upper altitudes of the horizontal contour of the zone to be avoided, of current, maximum and optimum altitudes of the aerodyne, and of scheduled points of exit and of descent of the aerodyne,updating the current altitudes of the aerodyne, andinputting the point of change of altitude into the automatic piloting device.
