WEIGHT AND BALANCE
6.7 WEIGHT AND BALANCE DETERMINATION FOR FLIGHT
(a) Add the weight of all items to be loaded to the basic empty weight.
(b) Use the Loading Graph (Figure 6-13) to determine the moment of
all items to be carried in the airplane.
(c) Add the moment of all items to be loaded to the basic empty weight
moment.
(d) Divide the total moment by the total weight to determine the CG.
location.
(e) By using the figures of item (a)and item (d) (above),locatea point
on the C.G. range and weight graph (Figure 6-15). If the point fans
within the C.G. envelope, the loading meets the weight and balance
requirements.

The center of gravity (C. G.) of this sample loading problem isat 89.04 inches
aft of the datum line. Locate this point (89.04) on the C.G. range and weight
graph. Since this point falls within the weight - e.G. envelope, this loading
meets the weight and balance requirements.
IT IS THE RESPONSIBILITY OF THE PILOT AND AIRCRAFfOWNER
TO ENSURE THAT THE AIRPLANE IS LOADED PROPERLY.
