Landing Gear and Brakes

Question 1

What does positioning the landing gear lever to OFF do

Answer 1

The OFF position removes hydraulic pressure from the landing gear

Mechanical uplocks hold the landing gear up

Question 2

What is the purpose of the lever lock override trigger?

Answer 2

To bypass the landing gear lever lock under certain conditions

Question 3

A gear position light is not illuminated with the landing gear lever in the down position but the supplemental gear position light is green. What is the gear position?

Answer 3

The landing gear is down and locked

Question 4

What is the purpose of the landing gear transfer valve?

Answer 4

It allows the B hydraulic system to retract the landing gear under the following conditions:

Airborne, and
#1 engine N2 < 50%, and
Landing gear lever is positioned up, and
Either main landing gear is not up and locked

Question 5

What effect does the manual extension access door have on the landing gear operation?

Answer 5

Landing gear retraction is inhibited

Question 6

What does pulling a manual gear extension handle do?

Answer 6

Releases the respective landing gear mechanical uplock

Handle needs to be pulled to full extension, about 24”

Question 7

The landing gear configuration aural warning horn cannot be silenced beyond which flap setting?

Answer 7

Flaps beyond 25

10 degrees on test *****

Question 8

What supplies pressure to the alternate brake system if normal brake pressure is low?

Answer 8

Hydraulic system A

Question 9

What braking is available if both hydraulic systems A and B are lost?

Answer 9

Brake Accumulator

6 brake applications or the parking brake set for 8 hours

Question 10

Which brake systems provide anti-skid, locked wheel, touchdown, and hydroplane protection?

Answer 10

Normal and alternate brakes

Question 11

When does RTO braking automatically begin during a rejected takeoff?

Answer 11

When the forward thrust levers are returned to idle after reaching a speed of 90kts

Question 12

Landing with the autobrakes in RTO results in what braking?

Answer 12

No automatic braking

Question 13

What is the difference between autobrake 1, 2, 3, and MAX?

Answer 13

Deceleration rate
1 - 2.4 kts/sec
2 - 3.0 kts/sec
3 - 4.3 kts/sec
MAX - 8.3 kts / sec

Question 14

How is the autobrake system disarmed?

Answer 14

Manually overriding with the brake pedals

Speed brake lever moved to down

Thrust levers advanced

Switch OFF

Question 15

How is the brake accumulator pressurized?

Answer 15

Hydraulic System B

Question 16

In flight, how is a PSEU fault indicated?

Answer 16

No indication in flight, PSEU caution light is inhibited:

in flight, or
thrust levers advanced, or
for 30 seconds after landing
