Abstract

A method for controlling an unmanned aircraft includes determining a maximum flying altitude for a ground position of the aircraft, the method comprising: for each point from a plurality of ground points situated within a perimeter around the ground position of the aircraft, referred to as “surrounding points”, determining one or more intersections between firstly a circle, the centre of which is the point and the radius of which is the maximum authorized ground distance at this point, referred to as the “determination circle”, and secondly a vertical related to the ground position of the aircraft, the circle being contained in a vertical plane comprising the vertical related to the ground position of the aircraft; and for all of the intersections thus obtained, selecting the greatest altitude as the maximum flying altitude.
