Which tank feeds the left engine during normal operation?

Which tank feeds the left engine during normal operation?

• A. Left main tank
• B. Right main tank
• C. Forward fuselage tank
• D. Aft filler tank

Answer: (A)

Each engine has a dedicated primary feed from its respective main fuel tank. In normal operation, the left engine draws fuel from the left main tank, while the right engine draws from the right main tank. This arrangement provides reliable fuel pressure and balance, using straightforward, separated feeds rather than crossfeeding during routine flight. A crossfeed option exists to supply an engine from the opposite tank if needed, but it’s intended for abnormal situations or balancing, not normal operation. The forward fuselage tank and the aft filler tank are not the primary sources for engine fuel in normal operation; they serve other roles within the fuel system, such as capacity and balance.
