Which fuel tanks normally feed which engines?

• A. Usually, the left tank feeds the right engine and right tank feeds left engine
• B. Usually, the right tank feeds the right engine, and the left tank feeds the left engine
• C. The center tank feeds both engines
• D. Each engine is fed by all tanks equally

Answer: (B)

In a typical twin-engine aircraft, each engine is fed from the tank on the same side. The left engine draws fuel from the left wing tank, and the right engine draws fuel from the right wing tank. This keeps the fuel system simple and helps maintain lateral balance as fuel is burned. The center tank adds extra capacity and can be used to feed either engine via crossfeed when needed (for balance, longer range, or abnormal situations), but it isn’t the normal source for both engines. Feeding both engines from all tanks equally would complicate fuel management and isn’t how the system is designed to operate in normal conditions.
