There is no such thng as a dumb question if yuou are earnestly trying to learn. I thought the purpose of these forums were fro pweople tol earn about about a career or a recreational activity that we all love to due. Why the rude coments? I dont get it. I love to help people with aviation help. And as far as asking repeated questions, of course you are going to get the same quetions asked. New people come in with the same quetions. If all they had to do was do a search what would be the point of the forums. In that case probably every question has been asked at least five times, we might as wel tell everybody to search and nobody ask questions ever again. Is that the purpose of this site?
