Center Tanks transfer to wings at which percentages?

• A. 90% and 95%
• B. 93% and 97%
• C. 92% and 96%
• D. 94% and 98%

Answer: (B)

Fuel management in the CRJ-550 uses center tanks and wing tanks to keep the airplane balanced and ensure there’s enough fuel for all phases of flight. The transfer from center tanks to the wing tanks is allowed only within a narrow window of center-tank fullness. Specifically, transfer is permitted when the center tanks are between 93% and 97% full. This keeps the center tanks from being overfilled while making sure the wings can receive fuel to maintain proper weight distribution and meet landing fuel requirements. Outside this band, the system avoids transferring, which helps prevent unwanted shifts in center of gravity or fuel imbalances.
