WEIGHT AND BALANCE: (Cont'd)
The above empty weight includes unusable fuel of 27.6 lbs. at 24 inches and 8 quarts of oil
at minus 34 inches, plus all items of equipment as marked on the accompanying Equipment
Lists. The Certificated empty weight is the above weight less 16 lbs. drainable oil 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.

*Moments can be read directly from the loading graph.
By locating the point corresponding to 2434 lb. aircraft weight and a C.G. Location of
17.8 inches on the Center of Gravity envelope graph, you can see that this point falls within
the envelope, signifying the loading is acceptable.
