Question 7

1. What might cause a red “ACFT CONFIG” CAS message to illuminate during
   takeoff?

Answer 7

Flaps not at 10 or 20 degrees

Speedbrake handle not stowed

Question 8

2. If an engine is inadvertently started with the gust lock engaged, what is the
   appropriate procedure?

Answer 8

Shut down the engine and bleed the hydraulic pressures to zero before
Disengagement

Question 9

3. How is the external (single) rudder load limiter checked?

Answer 9

During engine starts, with the right engine operating and prior to starting the left
engine, the amber “SNGL RUDDER LIMIT” CAS message should be displayed
on the EICAS and the engine start page

Question 10

4. If an amber “SNGL RUDDER LIMIT” CAS message illuminates in flight, what is
   the corrective action?

Answer 10

Avoid abnormal rudder deflection

Question 11

5. How is the rudder torque limiter checked prior to flight?

Answer 11

Illumination of the blue “RUDDER LIMIT” CAS message with full rudder deflection

Question 12

6. Is the yaw damper required to be operative or engaged for autopilot
   operation?

Answer 12

The yaw damper must be operative and it will automatically engage when the
autopilot is selected ON

Question 13

7. What is the function of the GPWS ground spoiler flap override switch?

Answer 13

Provides ground spoiler deployment upon wheel speed spin-up in the event of a
partial flap landing
Inhibits the GPWS “TOO LOW, FLAPS” callout

Question 14

8. Is ground spoiler deployment available with a loss of combined system fluid?

Answer 14

Yes, the auxiliary hydraulic pump provides the “pop-up” signal and the flight
hydraulic system provides hydraulic pressure to move the ground spoiler panels

Question 15

9. What is the immediate action required if the red “GND SPOILER” CAS
   message illuminates in flight?

Answer 15

Immediately position the ground spoiler arming switch to OFF

Question 16

10. When conducting the ground spoiler preflight test, what are the proper
    indications when the “TEST” button is pressed?

Answer 16

The ground spoilers should remain stowed
A red “NO GND SPLR” light capsule illuminates on the glareshield
A red “GND SPOILER” CAS message illuminates
Both master warning light capsules illuminate

Question 17

11. During the cockpit preflight inspection, how can the flaps be set to 10 degrees
    in preparation for the exterior preflight inspection?

Answer 17

By activating the auxiliary hydraulic pump

Question 18

12. What hydraulic sources are available to operate the flaps using the emergency
    flap control?

Answer 18

Combined, utility and auxiliary

Question 19

13. If the FLAP CONT circuit breaker has tripped, what is the affect on the flap
    system?

Answer 19

Normal flap operation is not available

Emergency flap operation may be available

Question 20

14. If the MANUAL FLAP CONT circuit breaker has tripped, what is the affect on
    the flap system?

Answer 20

Both normal and emergency flap operation will be inoperative

Question 21

15. With a loss of essential DC bus power, what is the effect on the flap system?

Answer 21

Both normal and emergency flap operation will be inoperative

Question 22

16. How would a flap asymmetry condition affect flap operation?

Answer 22

Both normal and emergency flap operation will be inoperative

Question 23

17. What is the limitation regarding the use of the autopilot with emergency flap
    operation?

Answer 23

Do not engage the autopilot when using the emergency flaps unless flap
deflection is 10º or greater

Question 24

18. What is the first required action with an undesired flap movement?

Answer 24

Select the emergency flap switch to “EMERGENCY”

Question 25

19. When is the amber “STAB-FLAP FAIL” CAS message displayed?

Answer 25

When the flaps are fully up but the stabilizer is not fully up

Question 26

20. What are the resulting indications when emergency flaps are used?

Answer 26

A red “X” on both AOA indicators No valid auto-speed target (999 in the speed window) No valid perf computer speeds on the FLT REF page Autothrottles will disconnect A “FLAP INPUT INVALID” scratchpad message

Question 27

21. What flap setting would you use with a combined fluid loss (assuming you move them)?

Answer 27

Flaps 20, aux hydraulic pump operation is extremely slow (in case of Go-around)

Question 28

22. What is required to energize automatic ground spoilers upon landing if the flaps are less than 22°?

Answer 28

Power levers at idle and weight on wheels, or Power levers at idle with the GPWS ground spoiler flap override switch selected ON and wheel speed spin-up

Question 29

23. What is normally indicated by a red “X” on the AOA indicators?

Answer 29

Emergency flap operation is in use and AOA indications may not be reliable

Question 30

24. What is the limitation regarding the use of the autopilot with emergency flap operation?

Answer 30

Do not engage the autopilot when using the emergency flaps unless flap deflection is 10º or greater
