Abstract: A flight management system for an aircraft, includes a critical first avionics module for trajectory calculation, i.e. a module the integrity level and availability level of which are specified by regulatory standards in force, delivering as output a safe trajectory, based on a flight plan; a second module for trajectory calculation that is less critical than the critical first module, i.e. a module the integrity level and availability level of which are lower than those of the first module, delivering as output an improved trajectory that is less safe than the trajectory delivered by the critical first avionics module, based on a flight plan; a critical avionics module for trajectory verification, configured to validate or invalidate the safety of the less safe improved trajectory; and a critical avionics module for decision-making configured to select a trajectory from the safe trajectory and the less safe trajectory.

Abstract: A flight management system of an aircraft includes a first non-critical or open world module for creating an enhanced enriched flight plan, the first module being configured to create the enhanced enriched flight plan iteratively by the following steps: initialisation of pseudo-constraints; and iterative enhancement of the choice of pseudo-constraints, until an objective of enhancement or of absence of enhancement with respect to the last best choice of pseudo-constraints is reached, based on at least one optimisation criterion and on at least one parameter representative of the environment of the flight of the aircraft; the second critical or flight management avionics module certified to calculate a path, comprising at least one critical computer and/or at least one critical piece of software for calculating and delivering as output a secured path, based on the enhanced enriched flight plan supplied by the first module.
