Total the weights and moments/1000 and plot these values on the
Center of Gravity Moment Envelope to determine whether the point
ralls within the envelope, and if the loading is acceptable.

(5) Using weights from (3) and measurements from (4) the airplane
weight and C.G. can be determined.
(6) Basic Empty Weight may be determined by completing Figure
6-1.
WEIGHT AND BALANCE
The following information will enable you to operate your Cessna
within the prescribed weight and center of gravity limitations. To fig-
ure weight and balance, use the Sample Problem, Loading Graph, and
Center of Gravity Moment Envelope as follows:
Take the basic empty weight and moment from appropriate weight
and balance records carried in your airplane, and enter them in the
column title YOUR AIRPLANE on the Sample Loading Problem.
NOTE
In addition to the basic empty weight and moment noted
on these records, the c.g. arm (fuselage station) is also
shown, but need not be used on the Sample Loading Prob-
lem. The moment which is shown must be divided by
1000 and this value used as the moment/ 1000 on the load-
ing problem.
Use the Loading Graph to determine the moment/1000 for each ad-
ditional item to be carried; then list these on the loading problem.
NOTE
Loading Graph information for the pilot, passengers, and
baggage is based on seats positioned for average occu-
pants and baggage loaded in the center of the baggage
areas as shown on the Loading Arrangements diagram.
For loadings which may differ from these, the Sample
Loading Problem lists fuselage stations for these items
to indicate their forward and aft c.g. range limitations
(seat travel and baggage area limitation). Additional
moment calculations, based on the actual weight and c.g.
arm (fuselage station) of the item being loaded, must be
made if the position of the load is different from that
shown on the Loading Graph.
