Lincoln Departure at KBFI

Air traffic control has revised the Lincoln Departure at Boeing Field (KBFI) in Seattle. It’s one of the VFR procedures used at to provide an orderly flow of traffic below the Seattle Class B airspace and to avoid TCAS alerts in airliners descending over KBFI into KSEA.

As noted below, the initial altitude on the Lincoln Departure (which may be renamed the Vashon South Depature) is now 700 ft. MSL.

The Lincoln Departure almost always begins from runway 14R. It now requires a climb straight ahead to 700 ft. MSL, then a level 180-degree turn into a close-in right downwind over the Duwamish River, remaining at 800 ft. As you approach the South Park Bridge, almost abeam the control tower, turn left toward a school bus parking lot and parallel the main streets that head west over the ridge. As you reach the ridge, climb no higher than 1000 ft. Continue on a track between the north tip of Vashon Island and Blake Island. When you cross the SEA 323 degree radial, you can climb to 1500 ft. At the shoreline, you can continue to 2500 ft.
