One post only.
This is a pilot's forum. We like to assume that others are also pilots (unless they declare otherwise). That means at the very least they post in a form and fashion that suggets they are pilots. You can call it snobbery if you like, but that is the way it is and the reason why you dont deserve any replies - sorry.
However, to be generous your question has also been done to death. Use the "search" function if you care to do so.
