Method and device for generating an optimum flight path intended to be followed by an aircraft

A device for generating an optimum flight path intended to be followed by an aircraft, the flight path being defined between a current point and a target point, the device comprising:

• a database comprising data related to obstacles,
• a first determination processor, configured for determining at least one obstacle intercepted by a direct flight path connecting an initial point to the target point, the obstacle or obstacles corresponding to data comprised in the database, the initial point corresponding to the current point in a first iteration, the initial point corresponding to an optimum extreme apex in the iterations following the first iteration;
• a second determination processor, configured for determining at least one visible lateral extreme apex of at least one intercepted obstacle, on either side of the direct flight path;
• an evaluation processor configured for assigning a rating to each section corresponding to a segment between a lateral extreme apex and the initial point, the rating being representative of its ability to meet a fixed objective, the best rating being assigned to the optimum extreme apex;
• a first storage module configured for storing, in a first memory, each lateral extreme apex with the rating assigned to it as well as the section between the initial point and the lateral extreme apex;
• a second storage module configured for storing in a second memory the section corresponding to the optimum extreme apex;
• wherein the first and second determination processors, evaluation processor and the first storage module and the second storage module are configured for being used iteratively until a section between an optimum extreme apex and the target point does not encounter any obstacle, the optimum flight path then being reconstituted backwards on the basis of the target point and all of the sections stored in the second memory;
• the device further comprising a transmission processor configured for transmitting the optimum flight path to a user device.
