Landing Gear and Brakes

Question 1

Landing gear indicator lights will illuminate RED if

Answer 1

Landing gear lever is not down and locked (with either thrust lever retarded to idle and below 800ft AGL)

Related l/d gear is in disagreement with lever

Question 2

AUTO BRAKE DISARM light is illuminated amber when

Answer 2

Speed brake lever moved to down detent during RTO or l/d
Thrust lever advanced during RTO or l/d (exept during first 3 seconds after touchdown or l/d)
Landing made with RTO selected
RTO selected on ground (self test for 1 to 2 secs)
Malfunction with Autobrake system

Question 3

RTO - Max brake pressure is applied when

Answer 3

Thrust levers are retarded to idle at or above 90kts

Question 4

Normal pre charge of the brake pressure

Answer 4

1000PSI

Question 5

Rudder pedals can turn to nose wheel up to

Answer 5

7* in either direction

Question 6

Nose wheel steering wheel (Tiller) turns nose wheel up to

Answer 6

78* in either direction
Overrides rudder pedal steering

Question 7

Autobrake available on Normal and Alternate braking systems?

Answer 7

No only Normal

Question 8

What stops the wheels spinning when gear is retracted

Answer 8

Snubbers in nose wheel bay
Brakes on main wheels

Question 9

What happens if the gear is damaged and it is retracted

Answer 9

Impact fittings prevent damage to the main wheel well and the gear stops retracting and freefalls back to down postion

Can’t be retracted until fitting is replaced

Question 10

When is nosewheel steering available

Answer 10

Nose gear is in down position and compressed by the weight of the a/c

Question 11

A leak downstream of the l/d gear transfer unit what will happen to alternate steering

Answer 11

It is lost

Question 12

What does the lockout pin do on the nosewheel steering

Answer 12

Depressurises nosewheel steering
Allows plane to be pushed back without depressurising HYD systems

Question 13

What HYD system powers alternate brakes

Answer 13

System A

Automatically supplies pressure to system if HYD system B is low or has failed

Question 14

What HYD system powers normal brakes

Answer 14

System B

Question 15

What pressurises the Brake accumulator

Answer 15

HYD system B

If both normal and alternate braking systems have been lost - can still provide several braking applications and apply parking brake

Question 16

Antiskid when Alternate brakes are in use

Answer 16

Applies to wheel pairs instead of individual wheels

Question 17

Normal and alternate antiskid protection provides protection from

Answer 17

Skid,locked wheel, touchdown and hydroplane protection

Question 18

To arm RTO prior to t/o what conditions must exist

Answer 18

On ground
Anti skid and autobrake operational
Wheel speed less than 60kts
Thrust levers at idle
Switch to RTO

Question 19

Speed at which RTO activates

Answer 19

Wheel speed of 90kts
Max braking applied when thrust levers are retarded to idle

Question 20

If a l/d is made with autobrake at RTO

Answer 20

No auto braking action occurs and the AUTO BRAKE DISARM light illuminates 2 secs after touchdown

Question 21

After l/d autobrake application begins when

Answer 21

Both thrust levers are at idle
Main wheels spin up

Question 22

L/d autobrake may be selected after touchdown before

Answer 22

Prior to decelerating through 30kts

Question 23

Disarming the autobrake happens when

Answer 23

Moving the speed brake lever to down detent
Advancing forward thrust lever exept during the first 3 secs after touchdown
Applying manual brakes

Question 24

The air/ground system - How many sensors and where are they located

Answer 24

6 sensors
Two on each gear
