Figure 4.3-30 Fuel Conversion 3

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.

EXAMPLE TWO:

Finding gallons required.

Given: Total pounds . . . . . 6000 pounds

Fuel weight . . . . . . 6.4 pounds per gallon

Find:

Total gallons required.

Solution:

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)
