WEIGHT AND BALANCE
The following information will enable you to fly your GA-7/Cougar within the prescribed weight and center of
gravity limitations. To calculate the Weight and Balance for your airplane, use the Sample Loading Problem (Figure
6-4), Loading Graph (Figure 6-5), and Center of Gravity Envelope (Figure 6-6) as follows:
1.
Record the Basic Empty Weight and Moment, as calculated in Figure 6-3 or from the Weight and Balance
Data Sheet, on the Sample Loading Problem Chart (Figure 6-4).
2.
Add all additional weights and their corresponding moments, obtained from the Loading Graph (Figure 6-
5) of items to be carried on the flight. Total the weights and moments.
3.
Plot the total weight and moment on the Center of Gravity Envelope chart (Figure 6-6). If the intersection
point is within the envelope, the loading is acceptable.
4.
Figure 6-7 shows seating and cargo arrangement and center of gravity locations.
