FSM,
Thanks mate for the prompt reply. I will try your advise & see how it
works, sorry didn't mean to hurt your brain

I know it has been
aumteen years since you last drove manual .....and once you go Auto
you don't want to go back!! the 1/60 rule I was aware of in
calculating ARC to RADIAL as you see in my post, the only thing
the RADIAL to an ARC is calutated a little bit different ....I guess
due to the fast speed upon entry, unlike the pist. & turbs. they
have slower speed for flying the ARC (I mean light Turbs.)
Cheers

And please don't hurt your brain you will needed to
program the FMS
Happy Flying ..... .well appreciated!
