There was a discussion that I was involved in some time ago (maybe almost a

I don't believe this is possible.

The best you can do is narrow the course down to the choice of several
hedings, but not just one.

I'm not following how it's not possible to calculate the heading unambiguously.
Two VORs give you two lines-of-position. You are where the LOPs intersect. If
your location is known unambiguously, and the location of the target
intersection is known unambiguously, there is one and only one direct route.


True. I was referring to a method that does not require a chart - use
of VOR's only.

At risk of being annoyingly persistent: what is that method that does not
require a chart and narrows the course down to a choice of several headings?
