What is the capacity of fresh potable water storage in gallons?

• A. 10 gallons
• B. 12.5 gallons
• C. 15 gallons
• D. 20 gallons

Answer: (B)

Fresh potable water storage is the amount of clean water the aircraft’s potable water tank can hold. For this airplane, that tank is sized at 12.5 gallons (50 quarts, about 47.3 liters). This fixed capacity provides enough water for cabin beverage service and galley use while keeping weight and space within limits. So the capacity is 12.5 gallons.
