747 Fuel loads index change (rounded).
Up to 53,000kg virtually 0 index change. (All main tanks filling).
53-65T moves forward 25 units. (Inboard Mains 2 & 3 filling).
65-73T moves aft 60 units. (Reserve tanks filling).
> 73T keeps moving forward. (Inboard Mains 2 & 3 filling and centre @ >110T).
Tankering of fuel in the centre tank on the previous sector may have masked an out of C of G loading, if this was redistributed during the stopover it may have left the A/C outside the C of G limits. (Removal of 25T from the centre wing tank would result in a rearward C of G change of almost 200 units.
However any load error during refueling would have been picked up by the A/C and generated a "> STAB GREENBAND" EICAS message which comes from the nose gear pressure switch during final prep indicating an error in any of the following, Loading, Weight, C of G.
