2.

Can an A/C be towed with inop brakes?
- A.
  
  Yes
- B.
  
  No
Correct Answer
A. Yes

Explanation
An A/C (aircraft) can be towed with inoperative brakes because the tow vehicle can provide the necessary braking force to slow down or stop the aircraft. Additionally, the tow vehicle can also control the speed and direction of the aircraft during the towing process. Therefore, even if the brakes on the aircraft are not functioning, it can still be safely towed.

3.

What do you NOT do when stopping an A/C
- A.
  
  Slam on the brakes
- B.
  
  Pump the brakes
- C.
  
  Gingerly push the brakes
Correct Answer
B. 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.

4.

Hydraulic pressure must be ____ (+__, -___) PSI during the duration of the tow
- A.
  
  2900, 300, 100
- B.
  
  3000, 300, 100
- C.
  
  2900, 400, 000
- D.
  
  3000, 300, 000
Correct Answer
B. 3000, 300, 100

Explanation
The hydraulic pressure must be maintained at 3000 PSI throughout the tow. Additionally, there should be a positive pressure of 300 PSI and a negative pressure of 100 PSI.

Rate this question:
5.

What is the maximum incline you can tow an A/C up?
- A.
  
  1 degree
- B.
  
  2 degrees
- C.
  
  3 degrees
- D.
  
  5 degrees
Correct Answer
C. 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 must you do prior to towing an A/C?
- A.
  
  Brakes are serviceable
- B.
  
  Ensure the brake accumulators are charged
- C.
  
  Turn the APU on
- D.
  
  Pull the A/C forward a slight bit
Correct Answer
B. 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.
