Answer 9

Override mechanism

Question 10

Which hydraulic systems does the THS operate with?

Answer 10

Green and Yellow

Question 11

If both ELACs were to fail, what would take control?

Answer 11

SECs but in alternate law

Question 12

Elevator servos operate in which modes?

Answer 12

Active, Damping and re-centring

Question 13

When does re-centring mode activate?

Answer 13

When there is no demand but hydraulic pressure

Question 14

Which ELAC is in control normally for Aileron control?

Answer 14

ELAC 1

Question 15

How is roll controlled with total electrical failure?

Answer 15

Mechanical rudder

Question 16

What happens to the rudder movement output when Slats are deployed with dual FAC failure?

Answer 16

Rudder moves to low speed

Question 17

When will the rudder pedals move?

Answer 17

Manual trim

Question 18

During a rudder servo jamming what mode would be activated?

Answer 18

Damping mode internally

Question 19

Which spoilers act as speed brakes in flight?

Answer 19

2,3 and 4

Question 20

Which spoilers carry out roll control?

Answer 20

4 and 5

Question 21

During a roll command exceedance what happens to the opposite wing?

Answer 21

spoilers retract

Question 22

How is flare law activated?

Answer 22

Rad Alt input

Question 23

Vertical accelerometers transmit the vertical acceleration of the aircraft to the ELACs and SECs. Where are they fitted on the aircraft?

Answer 23

Installed in the FWD cargo compartment

Question 24

What is the purpose of Flap CSU?

Answer 24

Converts mechanical inputs into electrical signals

Question 25

What computer controls the Flaps and Slats?

Answer 25

SFCC

Question 26

What function does the APPU provide?

Answer 26

Asymmetry feedback

Question 27

If one SFCC is faulty how does the aircraft use comparison signals for Asymmetry lockout?

Answer 27

The faulty SFCC automatically sends a Asymmetry signal making the serviceable SFCC master for Asymmetry lockout

Question 28

Slat 1 has four tracks, how many are driven?

Answer 28

2 are driven T2 and T3

Question 29

How can a Wing Tip Brake (WTB) be reset?

Answer 29

On the ground only via the MCDU

Question 30

Why is the position of the Flaps sent to the CIDS director?

Answer 30

For cabin lighting settings

Question 31

To prevent FOD ingress how are the Pack ram inlets controlled during take off and landing?

Answer 31

The BSCU sends a signal to the Pack controllers to close.

Question 32

When does Alpha lock keep the Slats out?

Answer 32

During high angles of attack

Question 33

What controls the landing gear retraction / extension sequence?

Answer 33

LGCIU

Question 34

The Hydraulic safety valve shuts off the hydraulic pressure to the L/G system, when the airspeed is greater than 260 ±5 kts. Where is this speed reference taken from?

Answer 34

ADIRU 1 & 3

Question 35

Which hydraulic systems control braking?

Answer 35

Normal Green - Alternative Yellow

Question 36

Which hydraulic system would you operate to top up the parking brake accumulator?

Answer 36

Yellow

Question 37

When will the braking DECEL light be illuminated?

Answer 37

The DECEL light comes on green when actual aircraft deceleration is 80 % of the selected rate (LO and MED modes) or 0.27g (MAX mode).

Question 38

What is the maximum Nose Wheel Steering (NWS) angle with the rudder pedals?

Answer 38

6 degrees

Question 39

What is the maximum Nose Wheel Steering (NWS) angle with the NWS tiller?

Answer 39

75 degrees

Question 40

Which LRU gives secondary gear information?

Answer 40

LGCIU 1

Question 41

How is the NLG returned to the centre position after take off?

Answer 41

2 centering cams, the lower cam is part of the plunger tube and the upper cam is part of the sliding tube. When the shock absorber is fully extended the pressure of the nitrogen causes the cams to engage. The wheels then return automatically to the centre position.

Question 42

What conditions must be met in order to arm the auto braking system?

Answer 42

The autobrake system is armed if one of the three modes P/B (LO, MED or MAX) is pressed. Green pressure available BSCU electrically powered no failure in the normal braking system
