How arrival metering works
When arrival demand exceeds safe airport capacity, an ADP spreads delays across inbound flights instead of letting airborne holding build up. Flights may receive controlled departure times from origin airports.
The headline average delay is a network measure; an individual flight can be better or worse depending on route, aircraft rotation, and airline recovery choices.
