Since mission requirements are based on pounds of fuel, the aircrew will need to convert
pounds to gallons in order to request fuel for the aircraft. This is because fuel trucks can
only reference gallons. Use the above formula, inserting the fuel weight on the outer wheel
above the 10, and find the gallons needed below the pounds required.
Finding gallons required.
Given: Total pounds . . . . . 6000 pounds
Fuel weight . . . . . . 6.4 pounds per gallon
Total gallons required.
Estimate the answer. Round the fuel weight down to 6 pounds per gallon. Divide
6000 by 6. Approximately 1000 gallons.
Find 64 (6.4#) on the POUNDS (outer) scale and place it over 10 on the GALLON
(inner) scale. (Figure 4.3-30)
Figure 4.3-30 Fuel Conversion 3
Find 60 (6000 pounds) on the POUNDS (outer) scale and read the amount of total
gallons on the GALLONS (inner) scale. (Figure 4.3-31)
