Brian,
I remember well how to move fuel. I did it often enough, as did we all. My comment was that if a STUDENT had caused an engine wind down by mishandling fuel why was he not corrected by a carefully monitoring screen.
I'm sure you remember humour too . . . (or perhaps you don't). I was pulling your leg. As an ex Flight Safety Officer too, I particularly understand the point you were making - THAT's why I was pulling your leg.
The 'method' was for other readers, not ex FEs.
Oh dear . . .
Perhaps I'll give this thread a miss, it's getting a bit too intense.
