BALANCE
5.1
WEIGHT AND BALANCE: (Cont'd)
The above empty weight includes unusable fuel of ** lbs. at 24 inches and 12 quarts of oil
at minus 34inches for the O-540 engine and 8 quarts of oil at minus 34 inches for the IO-
540 engine, plus all items of equipment as marked on the accompanying Equipment Lists.
The Certificated empty weight is the above weight less 24 lbs. drainable oil for the O-540
engine or above weight less 16 lbs. Drainable oil for the IO-540 engine at a minus arm of
34 inches and for this airplane is ______________lbs. The corresponding empty weight
center of gravity is ______________inches.
5. Calculations for determining weight, C.G. and moment:
a. Center of Gravity (inches) = L x T - D
W
i.e., C.G. = _____________ - ____________ = ___________inches.
b. Moment (inch pounds) = W x C.G.
i.e., Moment = _____________ x ____________ = ___________inch lbs.
EXAMPLE OF WEIGHT AND BALANCE CALCULATION FOR LOADED AIRCRAFT:
An airplane with an empty weight of 1549 lbs. and empty weight C.G. location of
11.2 inches is loaded with a pilot and front seat passenger, fuel and baggage.

By locating the point corresponding to 2377 lb. aircraft weight and a C.G. Location of
16.0 inches on the Center of Gravity envelope graph, you can see that this point falls
within the envelope, signifying the loading is acceptable.
*Moments can be read directly from the loading graph.
**Use 18 lbs. for “A” or “B” configurations and 27.6 lbs. for “C” or “D”.
