Next, the team developed
an RNP RNAV approach to runway 26, providing the first instrument
approach available to that runway. Because the approach literally
wound its way down a mountain valley, the flexibility of a system
based on Earth-referenced waypoints and linear containment surfaces
proved ideal for designing the new procedure. It required RNP
0.3 and has landing minimums of 337 ft with 1 mi of required visibility.
Subsequent RNP RNAV
procedures have been developed and approved for Sitka, Ketchikan,
Wrangell, Petersburg, Cordova, and Kodiak.
PROCEDURES ARE CURRENTLY AVAILABLE ONLY TO ALASKA AIRLINES.
