Which option correctly lists the cross-feed function on the fuel selector?

• A. Allows cross-feed to the wing
• B. Allows engine to draw fuel from the opposite tank
• C. Shuts off cross-feed
• D. Allows engine to draw fuel from the same tank

Answer: (B)

Cross-feed is the ability to route fuel between the two wing tanks so an engine can draw from the opposite tank. This is why the correct option states that the engine can draw fuel from the opposite tank—it lets you balance fuel or continue operation if one side is depleted. It’s not about feeding fuel to the wing, nor about simply shutting off cross-feed, nor about drawing from the same tank (that would be the normal feed from the engine’s own side).
