Answer 1

Any time normal brakes are not active

Question 2

Which hydraulic system is used for normal braking?

Answer 2

GREEN

Question 3

When braking without anti-skid (BRK A/SKID switch selected to
ALTN/OFF) the BRAKES indicator should be monitored to limit
brake pressure to what psi?

Answer 3

1,000 psi

Question 4

apply the selected AUTO BRK mode during a rejected takeoff?

Answer 6

85 KTS

Question 7

When the aircraft is being towed, which Nose Wheel Steering

controls are available?

Answer 7

No steering controls are available from the flight deck

Question 8

What temperature on any brake will cause the amber BRK

HOT light on the LDG GEAR panel to illuminate?

Answer 8

> 300C

Question 9

Via what two components is braking achieved?

Answer 9

Brake pedals or AUTO BRK system

Question 10

Which hydraulic system is used when normal brakes are not

available?

Answer 10

YELLOW

Question 11

Both generators fail in-flight. The standby generator fails to
automatically start. Which switch can manually start the
standby generator?

Answer 11

STBY GEN

Question 12

When is the anti-skid system deactivated?

Answer 12

ALTN/OFF is selected on the BRK A/SKID panel

Question 13

With the aircraft in approach or landing configuration, what is
indicated when the red arrow on the Landing Gear Control
panel is illuminated?

Answer 13

Landing gear are not down and locked

Question 14

An interlock mechanism prevents unsafe gear retraction until

the aircraft is in what configuration?

Answer 14

Three shock absorbers extended, nose wheel centered and

two main bogie beams aligned

Question 15

During normal operations, when is hydraulic pressure

removed from the nose wheel steering system?

Answer 15

Nose gear shock absorber extended, towing lever selected to

ground tow, or both engine fuel levers selected to OFF

Question 16

Which gear have brakes and A/SKID?

Answer 16

Main gear only

Question 17

In what position must the gear handle be to arm the

autobrakes?

Answer 17

The DOWN or OFF position

Question 18

How does the Normal anti-skid system prevent MLG wheel

lock/skidding?

Answer 18

It compares each pair of MLG wheels to the nose wheel

rotation

Question 19

How is aircraft directional control maintained after landing

with a Green hydraulic system failure?

Answer 19

Using rudder pedals and differential braking

Question 20

What is a way to disarm the autobrakes after landing?

Answer 20

Apply sufficient force to the brake pedals

Question 21

What is a difference between LO and MED Auto Brake settings?

Answer 21

LO – 8 sec delay, MED – immediate application

Question 22

What activates Auto Brakes?

Answer 22

The ground spoiler extension command

Question 23

How may the autobrakes be monitored for proper operation?

Answer 23

The green flow bars on the switch will illuminate when

aircraft’s rate of deceleration matches the mode selected

Question 24

An interlock system prevents unsafe gear retraction until the
aircraft is in what configuration?

Answer 24

Weight off wheels, nose wheel centered, and both main bogie

beams aligned

Question 25

How is the landing gear extended with a Green hydraulic

system failure?

Answer 25

Manually, using a gravity extension procedure

Question 26

Which wheels have anti-skid protection?

Answer 26

All eight MLG wheels

Question 27

When are autobrakes not available?

Answer 27

When using the Alternate brake system
