Скачать или смотреть RNAV Approach at KSHN

The Seattle area offers a variety of airports for IFR practice. This flight takes me from busy Boeing Field (KBFI) to Sanderson Field (KSHN) at Shelton, WA, a non-towered airport just 40 miles southwest of Seattle.

Flying approaches at Sanderson demonstrates how GPS has transformed IFR for light GA aircraft. The airport once had only an NDB approach. Now it has RNAV (GPS) procedures to both runway ends, and the approach to RWY 23, which you’ll see in this video, offers LPV minimums as low as 523 (250 ft AGL) and ¾ mi visibility, almost as good as those provided by a category one ILS.
The minimums are a little higher for several reasons—most importantly, RWY 23 does not have an approach lighting system to help guide you in during LIFR conditions.

During preflight planning, it’s important to review such details so that you’re not surprised by the view when you break out of the clouds, especially when you are arriving at a relatively quiet, rural airport like Sanderson Field.

Ride along as I explain some of the preflight planning process and describe how I use the Garmin G500 TXi, GTN 750Xi, and GFC 600 autopilot in the Beechcraft A36 Bonanza.
