Q

What is the difference between LOW and MED AUTO BRK?

A

• LOW – progressive pressure applied to brakes 4 seconds after ground spoilers deploy to decelerate
at 1.7 MPS.
• MED - progressive pressure applied to brakes 2 seconds after ground spoilers deploy to decelerate
at 3 MPS

Q

What does the AUTO BRK green DECEL light indicate?

A

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

17
Q

If you don’t see DESEL after landing , will you call DECEL?

A

Yes, if deceleration is felt by the crew and confirmed by speed trend on the PFD.

18
Q

What is the Takeoff setting for Auto Brakes?

A

MAX

19
Q

What will cause the MAX AUTO BRK to activate on a RTO?

A
  • Airspeed above 72 knots, and
  • Thrust Levers at IDLE, and
  • Ground spoiler extension
20
Q

If you lose Green hydraulic pressure will you have Auto Brakes?

A

No, not with the Alternate Brake system

21
Q

Is Anti-skid available with Alternate Brakes?

A

Yes, if certain conditions are met

22
Q

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

A

Yes – when at least one engine is in reverse AND the other engine is in idle

23
Q

How many brake applications are available with accumulator pressure?

A

Approximately 7 full applications

24
Q

What is the maximum brake temperature for takeoff?

A

300° C

25
Q

When should the brake fans be selected to ON?

A

ON when brake temperature exceeds 100°. OFF for takeoff when temperature below 150.

26
Q

What does the BRAKES & ACCU PRESS triple indicator indicate?

A
  • Yellow hydraulic pressure delivered to the left and right brakes
  • Yellow system brake accumulator pressure
27
Q

How do you perform the brake check during initial taxi?

A

Press the brake pedals to ensure the aircraft slows, and check the brake pressure on the triple indicator is
