    Is the anti-skid available when using the emergency brake?

    • Yes

    • No

    Correct Answer
    A. No
    Explanation
    The anti-skid system is not available when using the emergency brake. The emergency brake is a mechanical system that directly applies pressure to the brake pads or shoes, bypassing the anti-skid system. This means that when the emergency brake is engaged, the wheels can lock up and skid, leading to a loss of control. Therefore, the correct answer is "No".

    How long do the anti-skid lights stay on when testing is performed on the ground?

    • 3 seconds

    • 6 seconds

    • 10 seconds

    • As long as you hold the switch

    Correct Answer
    A. 6 seconds
    Explanation
    During ground testing, the anti-skid lights stay on for 6 seconds. This duration allows the tester to observe and analyze the performance of the anti-skid system. Holding the switch for an indefinite period of time is not necessary as the 6-second duration provides sufficient time to evaluate the system's functionality.
