    What part of a piston-type fuel-level control valve prevents fuel from entering the tank?

    • A spring

    • The float

    • A pilot valve

    • The diaphragm

    Correct Answer
    A. A pilot valve
    Explanation
    A pilot valve is responsible for preventing fuel from entering the tank in a piston-type fuel-level control valve. It acts as a gatekeeper, controlling the flow of fuel by opening and closing as needed. This valve is designed to regulate the fuel level and ensure that the tank does not overflow. By effectively managing the flow of fuel, the pilot valve helps maintain proper fuel levels in the tank and prevents any potential hazards or wastage.

    • Null

    Correct Answer
    A. Gravity
    Explanation
    Fuel transfers from the reserve tank on a tanker aircraft during flight due to the force of gravity. As the aircraft consumes fuel from the main tank, the fuel level in the reserve tank decreases. Since the reserve tank is located at a higher position than the main tank, gravity causes the fuel to flow from the reserve tank to the main tank, ensuring a continuous supply of fuel to the engines.

    On a tanker aircraft, what prevents the engine from running out of fuel and flaming out if its main tank is hit by small arms fire?

    • Automatic fuel monitoring system

    • Null

    • Crossfeed system

    • Fuel tank and engine sensing device

    Correct Answer
    A. Crossfeed system
    Explanation
    The crossfeed system is designed to prevent the engine from running out of fuel and flaming out if the main tank is hit by small arms fire. This system allows fuel to be transferred from one tank to another, ensuring a continuous fuel supply to the engine. By transferring fuel from an undamaged tank to the affected one, the crossfeed system ensures that the engine can continue running even if the main tank is compromised.

    You are troubleshooting a malfunction of the crossfeed system on a tanker aircraft when you determine the is no pressure available to route fuel to the crossfeed manifold. The most probable cause of this malfunction is

    • A malfunctioning boost pump.

    • FOD stuck in a shutoff valve.

    Correct Answer
    A. A malfunctioning boost pump.
    Explanation
    The most probable cause of the malfunction in the crossfeed system on the tanker aircraft is a malfunctioning boost pump. This is because the boost pump is responsible for providing the necessary pressure to route fuel to the crossfeed manifold. If the boost pump is not functioning properly, there will be no pressure available for fuel to flow to the crossfeed manifold, leading to the malfunction.

    What valve must be open to allow fuel to flow  from a cargo aircraft single point receptacle to the main wing manifold during ground refueling?

    • Refuel isolation

    • Right separation

    • Single separation

    • Single point receptacle drain

    Correct Answer
    A. Refuel isolation
    Explanation
    The valve that must be open to allow fuel to flow from a cargo aircraft single point receptacle to the main wing manifold during ground refueling is the Refuel isolation valve. This valve is responsible for isolating the fuel system during refueling operations, ensuring that fuel flows only to the desired tanks and prevents any potential leaks or contamination. By opening the Refuel isolation valve, fuel can be directed from the single point receptacle to the main wing manifold for proper distribution throughout the aircraft's fuel system.
