1. Cessna 172 Weight and Balance Created by Jordan Bradfield

2. Intended Learning Objective At the conclusion of this lesson, the student pilot will be able to complete a correct and accurate weight and balance of a Cessna172, given a pilot’s operating handbook and weight of the airplane.

3. Weight X Arm = Moment Very basic equation where you multiply the corresponding weight to its arm to find the aircraft’s moment. Arm-distance from an arbitrary line at which all distances are measured for balance.

4. Step 1: Find the corresponding weights; add them together and put the result in the total weight column. 1650.0 180.5 210.0 15.0 0.0 30.0 180.0 2235.5

5. Step 2: Multiply the weights and arms together to get the corresponding moments. Divide the total moment by the total weight to find the airplane’s center of gravity. 1650.0 180.5 210.0 0.0 15.0 180.030.0 64369.5 6714.6 7812.0 0.0 1455.0 8370.0 2235.588721.1 2235.539.69

6. Step 3: Plot the Center of Gravity on the graph according to your total weight and C.G. location. (Marked by blue dot) Step 4: ANALYZE: Since the dot is within the appropriate envelope (black outline), the airplane is within weight and C.G. limits for takeoff!

7. Step 5: Fly! Provided you have everything else required
