Published by the airport sponsor; voluntary unless ATC assigns it. If ATC assigns this route to you in Class B, C or D airspace, that assignment is an ATC instruction and compliance is required (14 CFR 91.123) — and “unable” remains available to the pilot in command.

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. 1 Depart RWY 32, then left crosswind westbound RWY 32 departure end The northwest end of 14R/32L — the surveyed 14R threshold. Runway heading 315 magnetic, 330 true.

  2. 2 AOB 1,700 MSL until here West Seattle ridgeline The bluff on the west side of the Duwamish valley, where sea-level industrial flats step up into West Seattle — about 30 ft to 260 ft inside half a mile, topping out near 350 ft. The ridge runs north-south for miles, so where you actually cross it depends on your leg; this pin is a representative point on the crest.

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.
