During Auto Cross Flow, fuel imbalance greater than how many pounds will trigger low tank filling until it is 50 pounds more than the other?

During Auto Cross Flow, fuel imbalance greater than how many pounds will trigger low tank filling until it is 50 pounds more than the other?

• A. 100 Pounds
• B. 200 Pounds
• C. 300 Pounds
• D. 400 Pounds

Answer: (B)

Auto Cross Flow is a system that automatically moves fuel from the fuller tank to the lighter one to prevent a large fuel imbalance from affecting the aircraft’s balance. It starts transferring when the difference between the left and right wing tanks exceeds a set threshold. That threshold is 200 pounds. Once it begins, it continues until the imbalance is reduced to 50 pounds, meaning the heavier tank ends up about 50 pounds heavier than the other. The other numbers don’t fit because they would either fail to trigger the system or would not match the designed balance target.
