the 600 has the inner tanks split so you have inner 1,2,3 and 4. The principle otherwise remains the same.
1 Centre to inners
2 each inner to 4000 kg
3 trim to inner
4 each inner down to 3500kg, then
5 outer to inner
The aft cg target is approx 2% ahead of the aft cert limit and it will forward transfer to 0.5% ahead of that until you get to 35 min before arrival (or FL245) and then it goes forward if not already.
