Answer 6

a. Nosewheel steering deactivated
b. Brake pressure is supplied by the Yellow hydraulic system
c. Anti-skid is deactivated
d. BSCU and ABCU are depowered
e. A 1,000 psi pressure limiting valve helps prevent wheel lock up

Question 7

Which hydraulic systems provide pressure to the brakes?

Answer 7

a. Normal brakes – Green
b. Alternate brakes – Yellow backed up by a hydraulic accumulator

Question 8

What are the four modes of braking?

Answer 8

d. Parking brake

Question 9

When do the Autobrakes activate on landing if armed?

Answer 9

When the ground spoilers deploy

Question 10

What is the difference between LOW and MED AUTO BRK?

Answer 10

a. LOW – progressive pressure applied to brakes 4 seconds after ground spoilers deploy to decelerate at 5.6 FPS
b. MED - progressive pressure applied to brakes 2 seconds after ground spoilers deploy to decelerate at 9.8 FPS

Question 11

What does the AUTO BRK green DECEL light indicate?

Answer 11

Actual rate of deceleration is within 80% of the selected rate

Answer 14

No, not with the Alternate Brake system

Question 15

Is Anti-skid available with Alternate Brakes?

Answer 15

Yes, if certain conditions are met

Question 16

With spoilers not armed will the spoilers deploy for an RTO?

Answer 16

Yes – when at least one engine is in reverse

Question 17

How many brake applications are available with accumulator pressure?

Answer 17

Approximately 7 full applications of brake pedals or parking brake or any combination thereof

Question 18

c. DMC 3 – Backup

Question 21

How can you tell if a DMC has failed?

Answer 21

“INVALID DATA” will be displayed in the respective EFIS/ECAM display units

Question 22

What happens when the upper ECAM display fails?

Answer 22

The E/WD automatically replaces the SD on the lower ECAM display

Question 23

If both the E/WD and SD display units fail, how can you display E/WD information?

Answer 23

Select the ECAM/ND switch to CAPT or F/O to transfer the E/WD to either ND
