Landing Gear/Brakes

Question 1

On approach to a wet runway, the antiskid inop light illuminates. How would you initially assess the situation?

Answer 1

A system fault is detected by the anti-skid monitoring system and you must refer to the QRH.
Previously computed PWB performance data is invalid.

Question 2

On approach when the anti-skid light illuminates. What guidance is there regarding all non-normal situations to help you in this scenario?

Answer 2

Carefully consider time available to complete all required corrective actions to include the QRH. If sufficient time does not exist prior to beginning final approach, execute a go-around.

Question 3

When anti-skid becomes inop, why is the PWB performance data no longer valid?

Answer 3

Antiski is inoperative and manual speedbrake deployment is required.

Question 4

What braking considerations are required with ANTISKID INOP?

Answer 4

The possibility of a tire blowout due to manual braking necessitates careful consideration of the QRH landing procedure review.

Question 5

Whcih system normally provides hydraulic pressure for landing gear retraction, extension, and nose wheel steering?

Answer 5

System A

Question 6

Is anti-skid protection available with alternate braking?

Answer 6

Yes, anti-skid protection is available with both normal and alternate braking systems.

Question 7

What protections are provided by the anti-skid system?

Answer 7

1. skid
2. locked wheel
3. touchdown
4. hydroplane

Question 8

What is the purpose of the loose tread impact fitting?

Answer 8

TO prevent a spinning tire with loose tread from retracting into the wheel well and potentially causing damage to wheel well components

Question 9

which system provides hydraulic power for normal brakes?

Answer 9

System B

Question 10

If hydraulic system B is low or fails, how will pressure be supplied to enable braking?

Answer 10

The alternate brake system is powered by hydraulic system A. If hydraulic system B is low or fails, hydraulic system A automatically supplies pressure to the alternate brake system.
The brake accumulator is powered by hydraulic system B. If both normal and alternate brake system pressure is lost, trapped hydraulic pressure in the brake accumulator can still provide several braking applications or parking brake applications
