    Rate this question:

  • 4. 

    What must you do prior to towing an A/C?

    • Brakes are serviceable

    • Ensure the brake accumulators are charged

    • Turn the APU on

    • Pull the A/C forward a slight bit

    Correct Answer
    A. Ensure the brake accumulators are charged
    Explanation
    Before towing an aircraft, it is important to ensure that the brake accumulators are charged. This is necessary because the brake accumulators store hydraulic pressure that is needed to operate the aircraft's brakes. If the accumulators are not charged, the brakes may not function properly during the towing process, which could lead to safety risks. Therefore, it is essential to check and ensure that the brake accumulators are charged before towing an aircraft.

    Rate this question:

  • 5. 

    What is the maximum incline you can tow an A/C up?

    • 1 degree

    • 2 degrees

    • 3 degrees

    • 5 degrees

    Correct Answer
    A. 3 degrees
    Explanation
    The maximum incline you can tow an A/C up is 3 degrees. This means that the A/C can be towed up a slope with an incline of up to 3 degrees without any issues. Towing the A/C up a slope with a steeper incline may cause difficulties or damage to the vehicle.

    Rate this question:

  • 6. 

    What do you NOT do when stopping an A/C

    • Slam on the brakes

    • Pump the brakes

    • Gingerly push the brakes

    Correct Answer
    A. Pump the brakes
    Explanation
    When stopping an A/C, you should not pump the brakes. Pumping the brakes is a technique used in older vehicles with non-ABS (anti-lock braking system) to prevent the wheels from locking up. However, modern A/C systems are equipped with ABS, which automatically modulates the braking pressure to prevent wheel lock-up. Therefore, pumping the brakes in an A/C can disrupt the ABS system's function and reduce its effectiveness in stopping the vehicle.
