How much fuel does each wing tank hold, and what is the center tank capacity?

• A. Wing tanks 9,100 lbs each; Center tank 20,000 lbs
• B. Wing tanks 9,100 lbs each; Center tank 30,500 lbs
• C. Wing tanks 8,500 lbs each; Center tank 30,500 lbs
• D. Wing tanks 10,000 lbs each; Center tank 30,000 lbs

Answer: (B)

The amount of fuel is set to balance range needs with stability. In this configuration, each wing tank holds 9,100 pounds, and the center tank holds 30,500 pounds. The wing tanks provide the necessary feed to the engines and help maintain lateral balance, while the larger center tank carries the bulk of the fuel for long flights and helps keep the aircraft’s center of gravity within limits as fuel is burned. This pairing reflects the aircraft’s certification and typical mission profile, ensuring enough total fuel while managing CG changes. The other options either reduce the center-tank capacity too much for long-range needs or alter the wing-tank capacity in ways that could upset balance and range.
