SyEng, have any A400M been flown with the additional Cargo Bay Tanks intended for the AAR role? Fuel from the CBTs will need to be pumped to the 'AAR gallery', although I cannot recall how the associated schedule is managed.
If 'AAR' software is enabled and the fuel system is 'expecting' to transfer fuel from CBTs which aren't actually fitted.......
And no, I have absolutely no idea whether the AAR software has yet been included in any A400M.
