Terry - thanks for the reply, but heading is not known.

Stefan - we need to be able to plug these known values into a formula
and kick out a result. Assuming the original responder was on the

ideas on that? I'm not lazy, this just went over my head a long time
ago. :-)

But the question was a different one. It has already been answered
