Instrument coverage

Port Angeles CGAS has a particularly narrow procedure set: its sole approach is a helicopter RNAV (GPS) procedure serving one runway end. The published instrument arrival coverage is therefore focused on helicopter operations rather than providing approaches to both ends of runway 08/26. The single 4,500 ft conventional runway also offers no second alignment, while the separate 100 ft H1 provides a designated helicopter area.

Surrounding chart coverage

Among nearby fields, Whidbey Island NAS has the broadest procedure coverage with 17 charts, followed by William R Fairchild International with seven. Friday Harbor has four, while Jefferson County International and DeLaurentis each have three, making their chart sets comparably thin. The Seattle Sectional supplies the broader visual-navigation context absent from this small instrument set.
