Dead reckoning? If the course intercept time and length are too difficult
to interpolate safely and fly the airplane, I'd request a position update in
5 minutes (7.5-10 miles closer), or the PT.

The no way to tell where you are part of your question should be (in my
limited experience) a BIG RED FLAG, both for the approach and how you
conduct the flight in general. Ultimately, keeping your butt out of the
rocks is solely up to you.

Question for this group.

I was being radar vectored for the SHN NDB approach. I was cleared in
the following way: Cessna 61786 14 miles from NDB descend and maintain
2000 until established.

The problem: I was outside the 10 mile ring on the plate, established
on the inbound course, no way to tell when I would be inside 10 mile.
However, I would need to descend to 1400 before the NDB to have a
chance to descend to MDA of 900.

What would you all do?
