A pilot, aiming for a flight at the Maximum Structural Take-off Mass (MSTOM), anticipates requiring either 3300 or 3200 pounds of fuel. Upon shutdown, they find 830 pounds of remaining fuel with a specific gravity of 0.82. How many liters of fuel are required during refueling?

  • A

    Approximately 1365 liters, if planning for 3300 pounds of fuel.

  • B

    Approximately 1365 liters, if planning for 3200 pounds of fuel.

  • C

    Approximately 830 liters regardless of the planned fuel quantity.

  • D

    Approximately 2470 liters for either planned fuel quantity.

Fuel on board = 830 lbs

830 lbs x 0.454 = 376.8 kg

376.8 kg with an SG of .82 = 460 Litres

If planning for 3300 Lbs:

3300 lbs x 0.454 = 1498.2 kg

1498.2 kg with an SG of .82 = 1827 Litres - 460 = 1367 Litres required, closest answer 1365 Litres

If planning for 3200 Lbs:

3200 lbs x 0.454 = 1452.8 kg

1452.8 kg with an SG of .82 = 1771 Litres - 460 = 1311.7 Litres required
