SkyCue24 — Airport Traffic Dashboard

How this is built: a background collector polls the same live feed as the map, and when an aircraft's track disappears from coverage it's classified as a landing or departure at NMI or BOM two ways: route — the callsign's real origin/destination airport (via a free public flight-route lookup), used whenever available; or heuristic — inferred from altitude and proximity when no route match exists (a track that starts low near an airport and climbs = departure; one that ends low and descending = landing). Route-based events are the reliable ones; heuristic events are a best-effort guess and are labelled as such in the table above. Airline names are resolved from the callsign, first from a small offline table, otherwise from the same live lookup (cached permanently per callsign so it's only ever queried once).
