Left/Right Wing Tank at Full: what is the gravity-based fuel quantity per wing tank?

• A. 7,290 LBS
• B. 7,492 LBS
• C. 4,610 LBS
• D. 14,580 LBS

Answer: (A)

This question tests how fuel capacity is expressed for each wing tank. In aviation, fuel quantity is given in pounds, which represents the weight of the fuel under gravity. When a wing tank is described as being full, the value given is the usable fuel weight that single wing can hold. For the CRJ-550, the usable capacity of one wing tank when full is 7,290 pounds. That means each wing, on its own, contains 7,290 pounds of fuel when full. If you needed the total fuel in both wings, you’d double that amount to 14,580 pounds. The other numbers wouldn’t reflect the amount in a single wing tank when full—they would correspond to either a different configuration or to the combined total for both wings.
