I have no idea what British flying schools are like -- and I mention that because most of the posters here seem to be British -- but I must say I've been amazed by some of the questions that pop up on this forum from time to time.
A lot of it seems to be basic stuff that any licensed pilot should already know, or which a student pilot should be asking his instructor.
Nevertheless, I wouldn't want to deter anyone from asking questions here if there's stuff they don't know and need to know.
As one of my theory teachers used to say: "There are no dumb questions in this classroom. The only dumb question is the one you fail to ask."
