Selecting the FUEL XFEED L TANK switch allows fuel from the left tank to supply which engines?

• A. Both engines
• B. Left engine only
• C. Right engine only
• D. Neither engine

Answer: (A)

Fuel crossfeed lets fuel be shared between the engine fuel systems. When you select the left-tank crossfeed, the left wing tank is connected through the crossfeed path to the right engine as well as to supply its own engine. This means fuel from the left tank can feed both engines, not just one. That’s why both engines can be supplied from the left tank under this setting.
