Where it actually is
North up. The sponsor names these landmarks and publishes no coordinate for any of them — everything positioned here is derived, and each coordinate's provenance is listed with its point below. Dashed markers are depicted: this site's reading of the written route, not published fixes.
- 1 Depart RWY 14, ground track about 115 RWY 14 departure end The southeast end of 14R/32L — the surveyed 32L threshold. Runway heading 135 magnetic, 150 true. satellite Apple Maps coordinate: FAA airport record (NASR), surveyed runway threshold
- 2 1 NM off the departure end 1.0 NM on 115 magnetic (129.8 true at the 2026 WMM declination of 14.9E). Then a slight right toward Southcenter. satellite Apple Maps
- 3 Overfly, then turn southbound. AOB 1,100 MSL Southcenter Mall A very large mall and its parking aprons on the floor of the Green River valley, at the I-5 / I-405 / SR-518 junction. satellite Apple Maps street view coordinate: OpenStreetMap contributors (ODbL)
- 4 Southbound, clear of the Class D Where a 180 track from Southcenter crosses the KBFI Class D boundary, 0.8 NM south. satellite Apple Maps
4.6 NM over 4 route points. Bearings are magnetic, converted from true at each leg's midpoint through the WMM 2025 model this site ships (14.8°E here).

Put it in the GPS
Route points become a route; reference points ship as waypoints only — a GPS that sequences you to a do-not-overfly marker has it backwards.
