Dudley, I know you're aware of this, but since this is a student
newsgroup I think it should be mentioned that it *is* possible to
obtain a reasonable position estimate using a single VOR.

No offense intended, but you might have missed a crucial point in
earlier posts in this thread. There was a contention that position could be
derived from a single VOR simply by knowing which radial the airplane was on
at a given moment.

No offense taken, and I didn't miss that point at all.

I thought I said so, but, it was probably too well hidden by too
many other words

My intention was only to explain an additional technique.

Perhaps a clearer way to make my point would have been to say,
while I agree two of *something* is needed, a 2nd VOR or ADF is
not needed; a 2nd radial from the same VOR, and a method of determining
the distance between them, may substitute.

Cheers,
Sydney
