    Ensure all fire pull handles are in what position for preparation of engine run ?

    • A.

      Pushed In

    • B.

      Pulled Out

    Correct Answer
    A. Pushed In
    Explanation
    To prepare for an engine run, all fire pull handles should be pushed in.

    For power runs the fire extinguisher must be left at the nose of the aircraft

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    For power runs, the fire extinguisher should not be left at the nose of the aircraft. This is because during power runs, there is a risk of engine fires or other emergencies. In such cases, the fire extinguisher needs to be easily accessible and ready to use. Therefore, it is recommended to keep the fire extinguisher closer to the operator or in a designated area where it can be quickly accessed in case of an emergency.

    How do you ensure brakes are set ?

    • A.

      If the handles stay foward, the brakes are set

    • B.

      Person C Visually checks the brakes

    • C.

      Pressure indicator reads 1500 psi

    • D.

      Brakes indicate SET on MFD 4

    Correct Answer
    B. Person C Visually checks the brakes
    Explanation
    The correct answer is Person C visually checks the brakes. This means that the person physically inspects the brakes to ensure that they are properly set. This method of checking is reliable as it allows for a direct observation of the brake system, ensuring that they are functioning correctly and securely. The other options, such as the position of the handles, the pressure indicator reading, and the indication on the MFD, may provide additional information but cannot guarantee that the brakes are set.

    How long after engine start must you allow the engine to stablize at idle?

    • A.

      5 Seconds

    • B.

      10 Seconds

    • C.

      5 Minutes

    • D.

      10 Minutes

    Correct Answer
    C. 5 Minutes
    Explanation
    After starting the engine, it is important to allow it to stabilize at idle to ensure proper lubrication and temperature regulation. This allows the engine's oil to circulate and reach all necessary components, preventing potential damage. Stabilizing the engine at idle for 5 minutes allows enough time for the engine to warm up and reach its optimal operating temperature, ensuring smooth and efficient performance.
