No ALIGNED candidate in the provided shortlist; the only entry KBED is behind the aircraft (Δhdg 169°). Current heading 140° points toward Cape Cod. The closest major airport on that heading is Hyannis (KHYA), bearing ~153° from current position, Δhdg ~12°, within the ALIGNED threshold. Distance (~37 nm) is consistent with final descent. Recent flight was to KBED, but that airport is now behind, suggesting a continuing journey. Confidence is moderate because KHYA is not in the pre-computed candidate table, but geometry supports it.
