chart, determine the weights and moment/100 for 390  gallons of Jet A fuel by interpolating between those  for 6.7 lb/gal and 6.8 lb/gal. The 390 gallons of fuel at  this temperature weighs 2,633 pounds, and its moment  index is 7,866 lb-in/100. 4.  Add all of the weights and all of the moment indexes.  Divide the total moment index by the total weight, and  multiply this by the reduction factor of 100. The total  weight is 14,729 pounds; the total moment index is  43,139 lb-in/100. The CG is located at fuselage station  292.9.  [Figure 9-45] 5.  Check to determine that the CG is within limits for  this weight. Refer to the Weight and Balance Diagram.  [Figure 9-46] Draw a horizontal line across the  envelope at 14,729 pounds of weight and a vertical  line from the CG of 292.9 inches aft of the datum.  These lines cross inside the envelope, verifying the  CG is within limits for this weight. Figure 9-45.
