Claim 6:
7. A system comprising one or more flight management system (FMS) computers, or on-board tablet-based or ground-based non-avionics navigation computers, for implementing the steps of:
determining an optimal continuous climb strategy for the climb phase, the optimal continuous climb strategy being determined depending on flight-profile parameters, said flight-profile parameters comprising altitude and/or speed constraints, and/or settings in respect of speed and/or thrust and/or level-flight avoidance and/or gradient-variation minimization, and allowing vertical climb predictions for the climb phase to be computed;
determining a lateral path, depending on lateral-path parameters comprising settings in respect of turn radius as a function of roll-angle settings, and depending on the vertical predictions for the climb phase computed for the flight-profile parameters; and
iterating the two previous stepson each constrained climb segment of the aircraft or drone climb path, a constrained climb segment being a segment of the climb path containing a binding constraint; then iterating the two previous steps over the entire climb path, while fitting in each iteration said flight-profile parameters and said lateral-path parameters, until all the binding constraints have been met one by one according to a predefined strategy,
wherein the iterating step consists of an incremental method for solving a binding constraint (Cn) for a constrained segment from a save point issued from the previous constrained segment (Cn−1), which save point is re-estimated in order to solve the binding constraint (Cn), the segment-by-segment fit leading to reconsideration of the i previous segments impacted by the solution of constraint n, the setting parameters selected being applicable to all of the constrained climb segments between (Cn−i) and (Cn).
