Hey ryankyle,

I feel your pain mate, I had a couple of goes at this one, she's a toughie.

I'll try explain it as I see it. What you need to think of is, where is the fuel in relation to the CoG? From memory.. and it should be, aft of CoG. So when there is LESS weight AFT, there is (relatively) MORE weight FWD, ie. the CoG moves forward. If you were to sit a couple of people on the tail, there is now more weight AFT and therefore the CoG moves AFT.
