Landing Gear & Brakes

Question 1

If the airplane is landed with 1200 psi on the brake accumulator gauge and the normal brakes fail, will the emergency brake be available?

Answer 1

No, it must be charged to allow braking

Question 2

What does the light in the landing gear handle indicate

Answer 2

If the handle is up- at least one gear door is not closed

If the handle is down- at least one landing gear is not down and locked

Question 3

What does the anti-skid system compare wheel speed to in order to evaluate if a wheel is in a skid

Answer 3

IRS groundspeed and wheel speed sensors

Question 4

From what hydraulic system can the parking/ emergency brake system be recharged?

Answer 4

AUX system

Question 5

If the parking/ emergency brake is used to stop the aircraft, what type of anti-skid protection is available?

Answer 5

None

Question 6

Where can individual brake temps be observed

Answer 6

On the BRAKES 1/6th synoptic page

Question 7

What does pulling the Emergency landing gear T handle do?

Answer 7

It repositions the dump valves allowing fluid to be returned to the reservoir and releases nitrogen to extend the landing gear

Question 8

How are the landing gear handle and the landing gear selector valve connected?

Answer 8

Electrically

Question 9

Explain how to set the parking brake

Answer 9

Pull the P-brake handle up, rotate 90°, and ensure brake accumulator pressure reads 1700psi

Question 10

How would failure of the gear door to close after landing gear retraction be indicated on the flight deck?

Answer 10

Red light in gear handle

Question 11

What is the first action that should be taken if the WOW circuit fails to shift to the airborne mode after takeoff

Answer 11

Turn off the ground spoiler arming switch

Question 12

What is the function of the dump valve switch on the overhead panel?

Answer 12

It resets the dump valves to hydraulic operation so that the
Landing gear can operate normally

Question 13

What is the accumulator pre-charge pressure for the parking/ emergency brake?

Answer 13

1200psi, increasing or decreasing 25psi for each 10°f above or below 70°f

Question 14

How are the landing gear doors opened for a preflight inspection

Answer 14

Install the door control valve pins, and open the doors by operating the ground service valve

Question 15

If closed landing gear up lock is discovered during preflight inspection, how can it be opened

Answer 15

Install the door control valve pins and open the unlock by operating the ground service valve

Question 16

During preflight inspections, what is the correct indication on the emergency landing gear extension bottle

Answer 16

3100psi at 70°

Question 17

What is the indication if the nose landing gear has been turned beyond its designed limit

Answer 17

The nose wheel steering unit over travel indication on the nose gear will trip. Indicating maintenance action required

Question 18

How can proper brake wear be determined

Answer 18

By observing the landing gear brake wear indicators, with the parking brake set

Question 19

Inflight, when should the brake accumulator be charged back to 3000 psi

Answer 19

Just prior to landing

Question 20

Where in the cockpit can the emergency gear extension bottle pressure be read?

Answer 20

On the hydraulics and summary synoptic pages

Question 21

At approximately how many degrees of travel will the over travel indicator pop up on the nose wheel steering collar

Answer 21

80 to 84°

Question 22

At approximately what pressure will the main tire over inflation safety plug release

Answer 22

450 psi

Question 23

At approximately what temperature will any one of the four main fusible plugs melt and release pressure

Answer 23

199°C

Question 24

What is the travel authority of the tiller steering

Answer 24

Variable rate steering +/- 80 ° <18 knots, decreasing to approximately +/-16°as IRS speed increases

Question 25

What is the normal pedal steering authority

Answer 25

+/-7°

Question 26

What is the pedal steering authority if the tiller steering should fail

Answer 26

+/-16°

Question 27

If an amber ANTI-SKID FAIL message is displayed n flight, should the anti-skid be turned off?

Answer 27

No, the anti-skid system may still be partially operative

Question 28

What is the normal nose wheel tire pressure?

Answer 28

115 psi

Question 29

What is the recommended maximum speed for use of the tiller wheel

Answer 29

60 KCAS

Question 30

If the blue NWS FIXED GAIN CAS message is displayed, what is the effect on the tiller steering

Answer 30

IRS input to the tiller is lost, and steering authority will be constant at all speeds
