I take it you didn't read my reply to you when I merged and closed your last four threads?
Pprune is not an answer machine. I'm quite happy to entertain technical discussions that increase your understanding of a topic (though this type of question should be in Tech Log), but I won't have you using Pprune as an alternative to reading your study notes.
If you want your ATPL, do the work. AND TURN YOUR BLOODY CAPS LOCK OFF!!
