Microburst2002,
Now I see, LEM probably ment "But the outers are empty".
So you cannot fill the outers because wet inners high level sensors result in stopping the fueling. So your max amount will be aprox. 1400kg less. Should be a problem in very rare occasions I guess. Interesting to know though.
Meikleour,
I don' t think stab position difference is such a big issue in order to start ground fuel transfer process.
And as mentioned before, in the MEL, even failed open tranfer valves are dispatchable cat C (ten days) and the operational procedure only draws attention to the unusual fuel distribution.
