After a morning flight to Anchorage, you're on your way back to Dutch Harbor for the night. The weather is typical of the Aleutian Islands in the winter: horrendous. Dutch Harbor is reporting a 2,500-foot ceiling, with gusty 36-knot winds from the northeast and heavy snow.

You are 16 miles southeast of the Dutch Harbor Airport (PADU), descending out of 13,000 feet. Fly the NDB-A approach with your copilot's help, and after you break out, circle west of the airport to land on runway 30.
