Hi,

I've gone on a few flights with the CS 777-300ER and from what I've noticed, if I don't modify anything, I'd only be consuming fuel from the Engine 1 and 2 reserves.

Now I understand there's quite a discrepancy because of the dependence on Asobo's 747 model, but here are my questions:

• Can I consume fuel from the center tank, or the non-existent engine 3 and 4? What do I need to do to draw fuel from them too?
  
• Does loading fuel on engines 1 and 2 only and keeping engine 3 and 4 empty affect flight performance in any way? MSFS implies that this affects CG but does it really?
  

Hope you can help with this, because I know you refuse to change the fuel management to move it away from the 4 engine 747 and this is the biggest annoyance/frustration of the whole CS-777 aircraft.
