Nepoleon,
sorry if you viewed my comment as negative. They weren't meant to be at all. Like you, I have asked similar questions and always appreciated the feedback.
The point that I was making is that the same questions seem to be asked repetitively. If you go back through the archives you can find the same threads with the same info in them all over the place.
I was suggesting that FAQ's such as this could be made into a reference library, taking PPRuNer's comments from the past that Wannabees can refer to in the future.
I'm certainly not discouraging your quest for knowledge.
Cheers, H&H
