PM - Leder has taken this off thread by PM since it is 'off topic', but for you - of course if it is in the company manual it is 'correct' for a company pilot to do it. However, I have often heard pilots describe the (500kg) fuel remaining in the centre tank (following AD2002-19-52) as 'unuseable' - which it is not. The confusion I have is:
1) It seems to apply to post-mod a/c
2) If so, why not just run the tank normally? What does fiddling around with single-pump ops achieve? I can see no advantage and would be interested in the logic.
Do you have an AD ref for this procedure?
Perhaps a new thread is required or you can join the PM trail?
