Jet A fuel has  a nominal specific gravity at +15 °C of 0.812  and weighs 6.8 pounds per gallon, but at +25 °C,  according to the Density Variation of Aviation Fuel  Chart  [Figure 9-44] , it weighs 6.75 lb/gal. Using this  2.  The weight of the baggage in each compartment used  is entered with its moment/100. This is determined  in the Weights and Moments—Baggage table.  [Figure 9-43]  1. The crew weight and the weight of each passenger is  entered into the manifest. The moment/100 for each  occupant is determined by multiplying the weight by  the arm and dividing by 100. This data is available in  the AFM and is shown in the Weight and Moments—  Occupants table.  [Figure 9-42] Figure 9-43.  Weight and moments—baggage. Figure 9-42.  Weight and moments—occupants.
