POWERED RUD 1 / 2 PUSH OFF in amber

Question 12

What annunciator is displayed in the event of a spoiler jam

Answer 12

FLIGHT / CONTORL SPLR 1/2 on Glareshield panel & ROLL SPLR INBD/OUTBD GND on CWP

Question 13

Each hydraulic system powers a PCU attached to each elevator?

Answer 13

True sys1 / sys2 / STBY sys

Question 14

What causes auto powering of the Standby PCU’s?

Answer 14

1 / 2 hydraulic systems fail

Question 15

What does FCECU stand for?

Answer 15

Flight Control Electronic Control Unit

Question 16

When moving flap from 15 - 35 deg, does autotrim occur?

Answer 16

Yes

Question 17

PITCH TRIM caution light illuminates why?

Answer 17

FCECU detects inability to control either pitch trim acutator or airspeed varies by more than 17kts

Question 18

ELEVATOR FEEL caution light illuminates why?

Answer 18

FCECU detects inability to control elevator feel below 200kts or airspeed varies by more than 17kts or normal acceleration is sensed to be invalid.

Question 19

ELEVATOR Asymmetry

Answer 19

FCECU detects mismatch between elevator positions with airspeed < 200kts

Question 20

ELEVATOR PRESS meaning?

Answer 20

FCECU detects all 3 PCU’s are powered

Question 21

Who has what controls after the ROLL HANDLE DISCONNECT is pulled?

Answer 21

CPT controls Spoilers

FO controls Ailerons

Question 22

ROLL OUTBD & ROLL INBD meaning?

Answer 22

Adivsory that all spoilers are extended

Question 23

ROLL SPLR INBD / OUTBD on the ground?

Answer 23

FCECU detects spoiler fault on ground

Question 24

SPLR OUTBD meaning?

Answer 24

FCECU fails to lockout or enable outboard spoilers at speed

Question 25

With flaps retracted do you have full rudder deflection

Answer 25

No only when flaps are extended

Question 26

1 OR #2 RUD HYD meaning?

Answer 26

FCECU has shut down that PCU due to a malfunction

Question 27

RUD CTRL meaning?

Answer 27

FCECU cannot control rudder / fail of both HYD sys / Airspeed > 17kts diff

Question 28

FLAP POWER meaning?

Answer 28

FCECU has locked flaps in last position

Question 29

FLAP DRIVE meaning?

Answer 29

Flaps operate at reduced rate

Question 30

1 OR #2 STALL SYST FAIL meaning?

Answer 30

Failure of respective Stall system

Question 31

PUSHER SYST FAIL on ground meaning?

Answer 31

Illuminates 30 sec after landing - single stick shaker failure

Question 32

Which control column is directly connected to the spoilers?

Answer 32

Captain side

Question 33

What happens to the pressure to the rudder actuators as the speed increases?

Answer 33

As airspeed icreases, FECEU reduces the hydraulic pressure available to the PCU’s. Inputs from either rudder pedals cause less rudder deflection.

Question 34

What controls the pressure to the rudder actuator?

Answer 34

FCECU

Question 35

What will happen if pressure is lost on one rudder actuator?

Answer 35

If either hydraulic system is lost, the remaining PCU provides rudder control

Question 36

What will happen if both rudder PUSH OFF buttons are pressed at the same time?

Answer 36

Both RUD1 and RUD 2 “PUSH” lights come on, and neither rudder PCU will depressurise.

Question 37

Which control(s) do the gust lock lock?

Answer 37

Ailerons

Question 38

What controls the rate of the pitch trim?

Answer 38

FCECU controls pitch trim rate depending on airspeed data from ADC.
Below 150 KIAS trim operates at high speed.
Above 250 KIAS trim opeartes at low speed
Trim rate is adjusted between these airspeeds

Question 39

When does the ELEV PRESS caution light illuminate?

Answer 39

When all 3 HYD systems are providing pressure to the elevators.
ie HYD #3 ISOL VLV is open

Question 40

What does the ELEV FEEL caution light indicate?

Answer 40

One FCECU channel can’t control its elevator feel actuator

Airspeed #1 mismatches Airspeed #2 by 17 knots or more (IAS MISMATCH on PFD + RUD CTRL, SPLR OUTBD, PITCH TRIM cautions also illuminate)

Normal acceleration parameter is not valid

Question 41

For the spoilers to extend on landing, the FCECU and PSEU must recieve valid input signals from what two places?

Answer 41

Both power levers are less than flight idle +12*
Weight on wheels sensors detect main landing gear is on the ground.

The flight taxi switch must also be in the flight position and hydraulic pressure must be available.

Question 42

What does the ROLL SPLR INBD HYD master caution mean?

Answer 42

No. 1 hydraulic system pressure is less than 900psi or the SPLR 1 PUSH OFF switchlight has been pushed.

Question 43

What does the ROLL SPLR OUTBD HYD master caution mean?

Answer 43

No. 2 hydraulic system pressure is less than 900psi and KIAS <165, or

The SPLR 2 PUSH OFF switchlight has been pushed and KIAS <165 or

Spoiler cable failure
