Excuse accidental send. One of the hazards of one handed computing.
Thanks very much for the link. I wasn't looking forward to firming up the assumptions and unrounding the round numbers.

I did Electronic Engineering and you can't avoid maths there. Glad you made sense of my explanation.

Hello Declan,

Greetings from Nova Scotia. Your "dodgy" math is essentially correct
and the reverse of how mariners have calculated their latitude from the

Fortunately, there are a number of good online calculators that will do
all the math for you
