Only OMAA is ALIGNED (Δhdg 19°, well within the 25° threshold) at 1101 nm, a plausible final-leg distance at 482 kt. The briefing lists OMAA as home base, and while the plane departed from OMAA on multiple recent trips, it did not return there on the latest flight history; however, no ALIGNED recurring or recent airport is available. All other candidates have Δhdg ≥ 35° and thus are off-track or behind the aircraft, and the past prediction record (1/7 correct) warns against speculative guesses, so OMAA is the strongest geometric and logical choice.
