CENTER OF GRAVITY = is the point about which an aircraft would balance if it were suspended at that point.

CENTER OF GRAVITY LIMIT = The specified forward and aft or lateral point beyond which the Center of Gravity must not be located during Take Off, Landing and Flight

CENTER OF GRAVITY RANGE = is the distance between the forward and aft C>G limit.

DATUM = is imaginary reference point use for weight and balance purpose only.
