Landing Gear and Brakes

Question 1

There are how many Air/Ground sensors?

Answer 1

6

Two per landing gear strut

Question 2

If there is a fault on the proximity switch electronic unit, how is the crew notified

Answer 2

On the ground only (inhibited from when the thrust levers are advance toward takeoff power until 30 seconds after landing)

The PSEU light on the aft overhead panel

Question 3

When will the landing gear indicators illuminate red?

Answer 3

When the landing gear position disagrees with the handle position

When the landing gear is not down and locked, with either thrust lever at idle, and the aircraft is below 800 ft AGL

Question 4

The landing gear warning horn cannot be silenced at any time with the flaps greater than ___ or below ____ ft RA and any gear is not down and locked

Answer 4

10 deg. below 200 ft RA

Question 5

Hydraulic system ___ normally supplies pressure for gear retraction

Answer 5

System A

Question 6

How are the wheel stopped during retraction?

Answer 6

Main gear - brake application

Nose gear - Snubber

Question 7

If a landing gear tire is damaged during takeoff, how does the aircraft prevent damage to components in the wheel well?

Answer 7

During retraction the tire will contact a fitting in the wheel well opening, the fitting breaks and the hydraulic pressure is reduced in the landing gear retract line. The landing gear free falls back to the down position

Question 8

The manual extension for the landing gear in the flight deck must be pulled out approximately ____ in. to initiate extension

Answer 8

24 in.

Question 9

What other protection occurs if the Manual Extension Access Door is open?

Answer 9

The landing gear retraction function is disabled

Question 10

Tiller Steering Angle?

Rudder pedal steering angle?

Answer 10

78 deg

7 deg.

Question 11

If using the alternate brakes, what system is no longer available?

Answer 11

Autobrakes

(Antiskid is still available)

Question 12

The hydraulic brake pressure accumulator is powered by which system

Answer 12

Hydraulic System B

Question 13

How is the crew alerted to a fault in the anti-skid system?

Answer 13

The ANTI SKID INOP light illuminates

Question 14

T/F: If the anti-skid system fails, the autobrake system is still operational

Answer 14

False

Question 15

T/F: Anti-skid protection is available even with the loss of both hydraulic systems

Answer 15

True

Question 16

The autobrakes disarm and the AUTO BRAKE DISARM light illuminates when:

Answer 16

SPEED BRAKE lever is moved to the down detent

Manual braking is applied

The RTO position is selected for landing

The AUTO BRAKE selector is moved to the OFF position

Malfunction exists in the system

Thrust levers are advanced (unless it occurs within 3 seconds after touchdown)

Question 17

To arm RTO the following conditions must be met:

Answer 17

Aircraft on the ground

The wheel speed <60 kts

The thrust levers must be at idle

The system accomplishes a self test which is successful if the AUTO BRAKE DISARM light illuminates for two seconds then extinguishes

Question 18

The RTO function only applies maximum braking if:

Answer 18

Thrust levers are retarded to idle at or above 90 kts

Question 19

RTO is automatically disarmed when:

Answer 19

Aircraft is airborne

Question 20

Autobraking application begins when:

Answer 20

Both thrust levers at idle

Main wheels spin up

Question 21

Which provides more stopping power… MAX AUTO BRAKE or full pedal braking?

Answer 21

Full pedal braking
