New RNAV (GPS) Approach at KSHN
« on: December 11, 2015, 07:39:51 AM »
As of 10 December, KSHN has a new RNAV (GPS) RWY 5 approach. It features an LP line of minimums for pilots with an IFR-approved WAAS navigation box (and assuming that receiver has the appropriate system software, flight manual supplements, etc.) As far as I know, this the first approach with LP minimums in the Puget Sound area. The old GPS RWY 5 approach has been canceled. And now the final approach course aligns with runway 5.

To learn more about LP (Localizer Performance) approaches, see:

RNAV Quick Facts and the references cited in that FAA brochure.

Localizer Performance without Vertical Guidance

(LP) and Lateral Navigation (LNAV) LPs are non-precision approaches with WAAS lateral guidance. They are added in locations where terrain or obstructions do not allow publication of vertically guided LPV procedures. Lateral sensitivity increases as an aircraft gets closer to the runway (or PinS type approaches for helicopters). LP is not a fail-down mode for an LPV. LP and LPV are independent. LP minimums will not be published with lines of minima that contain approved vertical guidance (LNAV/VNAV or LPV).
