Thanks for your reply Keith.
As radials come from the VOR station - for me to have a 330 heading and a TO flag I MUST be on the reciprical so on 330-180 +150?
If I had the FROM flag showing on the same heading it would only show FROM once I had overflow the VOR station and was on the 330 radial?
Is that right? I must seem so dense but this does confuse me from time to time - moments of clarity then back to my normal level of understanding!!!!
