There are two fuel shut-off valves: one in the aircraft for normal use and one for maintenance below the fuel tank. Which statement is true?

• A. There are two valves: one in the aircraft for normal use and one for maintenance below the fuel tank
• B. There are two valves: one in the cockpit and one under the tail
• C. There is only a single valve
• D. Valves are located in the engine bay

Answer: (B)

Two fuel shut-off valves exist, one you operate from the cockpit for normal use and a second maintenance valve located under the tail. The cockpit valve gives the pilot immediate control to shut off fuel in flight or on the ground, while the maintenance valve provides a separate isolation point for servicing the fuel system without needing access to the cockpit or engine area. That’s why the correct statement is that there are two valves in those two specific locations. The other options don’t fit the actual layout: there isn’t just a single valve, the maintenance valve isn’t stated to be under the fuel tank, and valves aren’t located in the engine bay.
