North Flows Arrivals (red) and Departures (green)
Arriving jet aircraft execute final turns before entering the narrow 5 nautical mile (nm) corridor extending from the runways.
Departing jet aircraft are confined to a narrow corridor and can turn east once they reach 8 nautical miles and at least 4,000 feet in altitude. Jet aircraft turning to the west must continue north over the Duwamish industrial area before initiating their turns.
