The basic empty weight and moment provided are from the current weight and balance record. 2. Enter the weight of fuel for your flight based on gallons of fuel in the aircraft. Using the loading graph (Figure 6.6), find the weight of fuel value on the left side of the graph then follow the graph line across to the right until it intersects with the fuel line. At the intersection of the fuel weight value and fuel chart line, follow/draw a line on the graph straight down to find the fuel moment value. Multiply this number by 1000 to determine the moment (e.g. 240 intersects at 11.5 x 1000 = 11500). Enter the weight and moment values as for useable fuel in row 2. Enter the fuel weight (e.g. 240 lbs) in column 1 and the moment (e.g. 11500) in column 2. Reduced fuel is used only when overweight. Speak to your instructor about this. 3. Using the loading graph (Figure 6.6), find the combined pilot and front passenger weight value on the left side of the graph then follow the graph line across to the right until it intersects with the pilot & front passenger. At the intersection of the pilot & front passenger weight value and pilot & front passenger chart line, follow/draw a line on the graph straight down to find the pilot & front passenger moment value. Multiply this number by 1000 to determine the moment (e.g. 340 intersects at 12.6 x 1000 = 12600). Enter the weight and moment values for pilot and front passenger in row 3. Enter the pilot and front passenger weight (e.g. 340 lbs) in column 1 and the moment (e.g. 12600) in column 2. 4. Using the loading graph (Figure 6.6), find the rear passengers weight value on the left side of the graph then follow the graph line across to the right until it intersects with the rear passengers line. At the intersection of the rear passengers weight value and rear passengers chart line, follow/draw a line on the graph straight down to find the rear passengers moment value. Multiply this number by 1000 to determine the moment (e.g. 340 intersects at 24.8 x 1000 = 24800). Enter the weight and moment values for rear passengers in row 4. Enter the rear passengers weight (e.g. 340 lbs) in column 1 and the moment (e.g. 24800) in column 2. 5. Using the loading graph (Figure 6.6), find the baggage Area 1 weight value on the left side of the graph then follow the graph line across to the right until it intersects with the baggage in Area 1 line. At the intersection of the baggage in Area 1 weight value and baggage in Area 1 chart line, follow/draw a line on the graph straight down to find the baggage in Area 1 moment value. Multiply this number by 1000 to determine the moment (e.g. 20 intersects at 1.9 x 1000 = 1900). Enter the weight and moment values for baggage in Area 1 in row 5. Enter the baggage in Area 1 weight (e.g. 20 lbs) in column 1 and the moment (e.g. 1900) in column 2. 6. Using the loading graph (Figure 6.6), find the baggage Area 2 weight value on the left side of the graph then follow the graph line across to the right until it intersects with the baggage in Area 2 line. At the intersection of the baggage in Area 2 weight value and baggage in Area 2 chart line, follow/draw a line on the graph straight down to find the baggage in Area 1 moment value. Multiply this number by 1000 to determine the moment (e.g. 0 intersects at 0 x 1000 = 0). Enter the weight and moment values for baggage in Area 2 in row 6. Enter the baggage in Area 2 weight (e.g. 0 lbs) in column 1 and the moment (e.g. 0) in column 2. Enter the weight of the baggage to be carried in Area 2. 7. Calculate the total of all weights in rows 1 to 6, column 1 and enter this value into the weight column in line 7 column 1 (e.g. 2407), then calculate the total of all moments in column 2 (e.g. 108,100) and enter this value into the moment column in Line 7; Ramp Weight and Moment. Total weight for takeoff must not exceed 2407 lbs. 8. Determine the weight of fuel that will be used for engine start, taxi, and runup. Enter the weight value in the weight column 1 (e.g. -7) and the moment in the moment column 2 (e.g. -8). Calculate the moment as you did in 2. table calculation for fuel and enter the moment value in the moment column for Line 8. 9. Calculate the total take-off weight by subtracting the value in line 8 from the value in line 7 (weight). Calculate the total take-off moment by subtracting the value in line 8 from the value in line 7 (moment). Using the graph (Figure 6.7), plot the weight and moment to ensure that they intersect within the center of gravity moment envelope. Enter these amounts in Row 9 columns 1 (e.g. 2400) and 2 (e.g. 107.8). 10. Calculate the Center of Gravity (CofG) by dividing the total moment by the takeoff weight in Line 9. Enter this value

into Line 10 on your table. This is the center of gravity for your departure. Using the Center of Gravity Limits Graph (Figure 6.8), plot the takeoff weight and CofG to ensure that your center of gravity limits are within the envelope.
