that sounds like very good advice about interpolating, of course a shorter line will have far less angle accuracy than a longer one. will do that from now on - thanks John
might try and see if Bob will answer me if I ask on his forum for Bob specific question next time - thaks wish
I have to say though I am pulling my hair out on all of those dodgy blurry lined charts in the VFR day booklet, okay to get a fairly rough figure but not so good for the pin point accuracy they seem to ask for
