13
Q

How does a BOOSTED brake work?

A

Depressing the pedal pulls ROD and forces fluid to brakes

More pressure more fluid provided by SPOOL valve

Q

What is DEBOOSTING?

A

Pressure reducer for effective brake control

17
Q

What is ANTISKID?

A

Prevents individual wheel skids

18
Q

What do we use fro EMERGENCY brakes?

A

CO2

Brake accumulators

19
Q

What are the 2 primary inspections done on a small aircraft brake?

A

Brake wear

Hydraulic leak

20
Q

How is break wear determined?

A

Length of brake return PIN

Thickness of disc/pad

21
Q

How do we perform brake wear check on large aircraft?

A

With brakes ON

22
Q

Air in the system or brake line deterioration can cause what?

A

Spongy brakes

23
Q

What are the 2 ways of bleeding the brakes not equipped with power brakes?

A

Gravity and pressure

24
Q

A locked wheel can cause what?

A

tire wear
rupture
slip

25
Antiskid systems are designed to send what if the wheel decelerates too rapidly?
Brake release order
26
What does a BRAKE RELEASE ORDER do?
Sends fluid back to return, bypassing the brake
27
What are the 3 components of the ANTISKID system?
Wheel Speed sensors Control valves Antskid computer
28
3 main functions of the control unit?
1. electrical signal used by control valve 2. regulate brake pressure 3. prevents brakes applied before touchdown
29
When is the antiskid system fully active?
20mph+
