WEIGHT AND BALANCE.
The following information will enable you to operate your Cessna
within the prescribed weight and center of gravity limitations. To figure
the weight and balance for your particular airplane, use the Sample Prob-
lem, Loading Graph, and Center of Gravity Moment Envelope as follows:
Take the licensed Empty Weight and Moment/1000 from the Weight
and Balance Data sheet, plus any changes noted on forms FAA-337,
carried in your airplane, and write them down in the proper columns.
Using the Loading Graph, determine the moment/1000 of each item to be
carried. Total the weights and moments/1000 and use the Center of
Gravity Moment Envelope to determine whether the point falls within the
envelope, and if the loading is acceptable.
