C. G. RANGE AND WEIGHT INSTRUCTIONS
1.
Add the weight of all items to be loaded to the licensed empty weight.
2.
Use the loading graph to determine the moment of all items to be carried in the airplane.
3. Add the moment of all items to be loaded to the licensed empty weight moment.
4. Divide the total moment by the total weight to detennine the C.G. location.
5.
By using the figures of Item 1 and Item 4, locate a point on the C.G. range and weight
graph. If the point falls within the C.G. envelope, the loading meets the weight and balance
requirements.

this
point
falls within the weight-C.G. envelope, this loading meets the weight and balance requirements.
IT IS THE RESPONSIBILITY OF THE PILOT AND AIRCRAFT OWNER TO INSURE
