Method for creating and choosing a determinate piloting strategy for an aircraft

A method comprising:

• generating an initial flight context;
• adding the initial flight context to a set of flight contexts stored at a context database;
• selecting a flight context that has a highest fitness value from the set of flight contexts, the selected flight context including a set of unresolved flight constraints, a set of resolved flight constraints, and a sequence of actions;
• computing a partial trajectory for all the actions of the sequence of actions when the partial trajectory can be computed;
• determining whether the partial trajectory is feasible when the partial trajectory is computed;
• determining whether the set of unresolved flight constraints is empty when the partial trajectory is feasible;
• yielding a piloting strategy corresponding to the selected flight context when the set of unresolved flight constraints is empty, otherwise:
• resolving at least one flight constraint of the set of unresolved flight constraints of the selected flight context to form at least one expanded flight context;
• adding the one or more expanded flight contexts to the set of flight contexts;
• and
• selecting again the flight context that has the highest fitness value from the set of flight contexts;
• and
• automatically piloting an aircraft unmanned according to the piloting strategy.

A method comprising:

• generating an initial flight context that includes a set of unresolved flight constraints;
• generating a decision tree based on the initial flight context, the decision tree including a plurality of flight contexts corresponding to leaves of the decision tree;
• expanding the decision tree according to a greedy best-first strategy that selects a flight context of the decision tree for expansion based on a fitness value assigned to the flight context;
• and
• selecting, as a piloting strategy, a flight context of the decision tree that includes a sequence of actions to resolve each of the unresolved flight constraints;
• and
• automatically piloting an aircraft according to the piloting strategy.
