Abstract: A route calculation for an aircraft is provided. The invention is based on defining grids representing an environment between at least one aircraft and at least one target point. The cells of the grid define absorption levels associated with the capability of the aircraft to cross a cell, making it possible in particular to define regions that are strictly inaccessible and regions for which penetration is tolerated. An interest level is diffused from at least one target point up to the position of the aircraft. When the interest reaches the aircraft, route segments are constructed iteratively between the aircraft and the target point, by going through those cells for which the interest is highest, and then the route is simplified for sending to a flight management system in order to be converted into a trajectory followed by the aircraft.
