Helps a lot!
Its what I suspected and what Phone Wind was getting at I think, but wasn't sure for certain that was the reasoning.
As for the what the JAA says on it...not much! Even the HP&L text book I have only says '
generally forbidden' and other articles (not from the JAA) I've read online say they are discouraged, but never seen anything to say they are completely banned or words to that effect.
