Abstract
The present invention relates to a method and a device for monitoring the minimum flying altitude of an aircraft. The method comprises a phase for calculating a vertical flight profile describing the changing altitude of the aircraft during an arbitrary period taking into account its instantaneous speed and its instantaneous angle of climb or descent; a phase for calculating a minimum vertical flight profile describing the changing minimum flying altitude over the future route of the aircraft during the period taking into account its instantaneous heading and its instantaneous speed, the minimum altitude values being determined for a coverage of the route of the aircraft during the period by disks centered on points on the route using requests to a database containing airspace zones corresponding to a minimum flying altitude, each request returning the zones intersected by a disk, the minimum altitude retained in a disk being the maximum value of the minimum altitudes for each type of zone returned; and a phase for generating a warning message based on the relative position of the vertical flight profile compared with the minimum vertical flight profile.
