    Tire pressure does not have to be checked prior to tow if it has been determined in the last 72 hours?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Tire pressure does not have to be checked prior to tow if it has been determined in the last 72 hours because tire pressure can remain relatively stable within that time frame. Checking tire pressure regularly is important for safe driving, but if it has been checked within the last 72 hours and no significant changes to the vehicle or driving conditions have occurred, it is generally considered acceptable to not check it again before towing. However, it is always recommended to double-check tire pressure before any long trips or if there are concerns about the tires.

    • ON

    Correct Answer
    A. OFF
    Explanation
    During an MLG tow, it is necessary to set the ANTI-SKID / BRAKE TEMP switch to the OFF position. This is because during a tow, the aircraft's anti-skid system should be deactivated to prevent any interference with the towing process. By setting the switch to OFF, the anti-skid system is disabled, ensuring a smooth and safe tow without any unintended braking actions or temperature buildup in the brakes.

    Rate this question:

  • 19. 

    When no emergency exists, slow the aircraft with the brakes is acceptable?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    When no emergency exists, it is not acceptable to slow the aircraft with the brakes. Braking should only be used when necessary, such as during landing or in emergency situations. Excessive use of brakes can cause damage to the aircraft's braking system and tires. Instead, pilots should use other methods such as reducing engine power or deploying spoilers to slow down the aircraft when no emergency exists.

    Rate this question:

  • 23. 

    Which hydraulic system is used for a normal NLG tow?

    • 2

    • 3

    • 1 and 4

    • 3 and 2

    Correct Answer
    A. 2
    Explanation
    The correct answer is 2. In a normal NLG (Nose Landing Gear) tow, only one hydraulic system is used. This system is responsible for providing the necessary hydraulic power to move and steer the NLG during the towing process. The other options (3, 1 and 4, 3 and 2) suggest the use of multiple hydraulic systems, which is not the case for a normal NLG tow. Therefore, option 2 is the correct answer.

    Rate this question:

  • 24. 

    During an MLG tow, the tow vehicle operator uses the tow vehicle to stop the aircraft?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    During an MLG tow, the tow vehicle operator does not use the tow vehicle to stop the aircraft. The purpose of an MLG tow is to move the aircraft on the ground, typically for maintenance or storage purposes. The tow vehicle operator uses the tow vehicle to pull or push the aircraft, but it is not responsible for stopping the aircraft. The brakes of the aircraft itself are used to bring it to a stop when necessary. Therefore, the correct answer is false.
