Claim 7:
8. A method, comprising:
identifying from live flight data for an aircraft that the aircraft has passed within a predefined distance of a fixpoint in a first segment of a current trajectory of the aircraft based on a sequence of flight samples from the live flight data; and
identifying from the live flight data that the aircraft has performed a turn relative to the first segment and in a known turn direction associated with a historical holding pattern charted from the fixpoint;
determining, from the live flight data and a trajectory of the aircraft, whether the known turn comprises a circuitous turn that forms a circuit with at least one additional turn in the trajectory of the aircraft, the first segment, and at least one leg segment;
generating, based on the historical holding pattern and whether the known turn is determined to comprise a circuitous turn, a classification or a likelihood determination indicating that the aircraft is currently in an uncharted holding pattern;
determining a baseline effect for at least one airport based on the holding pattern; and
diverting, based on the baseline effect, at least one aircraft traveling to the at least one airport to a new destination.
