AIRPLANE WEIGHING INFORMATION
At maximum gross weight, the center-of-gravity of a loaded airplane can move from 299.29 inches to
304.23 inches aft of Datum and remain within limits.
As the airplane is loaded, the center-of-gravity will shift. The amount of shift is dependent on not only
the weight added, but the distance the weight is placed from the original center-of-gravity. Both of these
factors can be considered by multiplying the weight added by the distance from the Reference Datum Line
to produce the loading moment. This information is presented in table form in the Crew and Passenger,
Cabinet, Baggage and Fuel Loading Moments tables.
The contribution each load station makes to center-of-gravity shift can be seen by comparing the
respective center-of-gravity arm lengths given in the Weight and Moment Table. Any weight placed in the
aft baggage bay will shift the center-of-gravity aft since it is aft of the typical standard empty weight
center-of-gravity.
Adding fuel, passengers or baggage (in the nose compartment) will shift the center-of-gravity forward
since all of them are loaded forward of the typical standard empty weight center-of-gravity. The magnitude
of the shift for any given weight is proportional to the length of the moment arm.
