WEIGHT AND BALANCE:
The above empty weight includes unusable fuel of ** lbs. at 24 inches and 8 quarts of oil
at minus 36.5 inches, plus all items of equipment as marked on the accompanying
Equipment Lists. The Certificated empty weight is the above weight less 16 lbs.
dra
inable oil at a minus arm of 36.5 inches and for this airplane is ______________lbs.
The corresponding empty weight center of gravity is ______________inches.

Center of Gravity (inches) =
i.e., C.G. = _____________
b.
Moment (inch pounds) =
i.e., Moment = _____________ x ____________ = ___________inch lbs.
EXAMPLE OF WEIGHT AND BALANCE CALCULATION FOR LOADED AIRCRAFT:
An
airplane with an empty weight of 1383 lbs. and empty weight C.G. location of 12.
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 2088
inches on the Center of Gravity Envelope graph, you can see that this point falls within the
envelope, signifying the loading is acceptable.
**Use 18 lbs. for “A” or
“B” tank configurations and 27.6 lbs. for “C” or “D”.
