In solo flight, the fuel balance constraint relates to the right aft cell level relative to the left side. What is the description?

• A. Right aft level cannot be double left
• B. Left fore level cannot be double right
• C. Both must be equal
• D. Imbalance must be greater on one side

Answer: (A)

The key idea here is that fuel balance helps keep the airplane’s center of gravity within safe limits by preventing too-large differences between tanks on opposite sides. In this description, the rule is that the right aft fuel cell level must not be twice the amount on the left side. Keeping the right aft tank from being more than double the left avoids shifting the CG too far aft or to the right, which would compromise stability and controllability, especially in solo flight when you’re managing everything yourself. If the rule were about the left fore tank being double the right, or if both sides had to be exactly equal, those would be different or overly strict constraints. And requiring that an imbalance must be greater on one side goes against the safety purpose of balance, which is to limit imbalance, not encourage it.
