CG
DANI
A CG of 25 % is a FORWARD CG, which is called nose heavy.
If you support the aircraft at its' CG, it will be in balance.
If the balance point is forward, the nose must be heavy in relation to the tail.
If the balance point lies far aft, the tail is heavy compared to the nose.
As far as landing CG is concerned - all computor loadsheets will show Zero Fuel CG, TakeOff CG and Landing CG.
If you make the loadsheet yourself with LPC laptop, you will only get a solution if all three mentioned CG's are within limits.
If you reposition large numbers of people, you, or your dispatcher will have to recalculate the loadsheet to check whether CG stays within limits for all conditions.
Note - reposition of normal quantities, e.g. some people to the bathroom, cabin attendents walking around with trollies, etc, are accounted for by setting the limits sufficiently safe.
