4. What happens when the FLT CONTROL A switch is positioned to STBY RUD?

Answer 4

-activates the Standby Hydraulic system and opens the Standby Rudder Shutoff Valve (allows the standby hydraulic system to pressure the Standby Rudder PCU)

Answer 6

-Ailerons and spoilers and both are hydraulically powered

Question 7

7. What happens when a single AILERON trim switch is pushed?

Answer 7

-nothing, it requires both switches to move together

Question 8

9. How many degrees of control wheel displacement initiates spoiler deflection

Answer 8

-10 degrees

Question 9

8. Why is aileron trim prohibited with the autopilot engaged?

Answer 9

-can result in an out of trim condition and an abrupt rolling movement when the autopilot is disconnected

Question 10

10. Which Flight Control Switch(es) are used for maintenance purposes only?

Answer 10

-the spoiler switches

Question 11

11. With a jammed or restricted Spoiler System, how is roll controlled?

Answer 11

-The captain’s control wheel will control ailerons only

Question 12

12. With a jammed or restricted Aileron System, how is roll controlled?

Answer 12

-The FO’s control wheel will control spoilers only

Question 13

13. What does an illuminated FEEL DIFF PRESS light (amber) indicate?

Answer 13

-excessive differential pressure within the Elevator Feel Computer

Question 14

14. How does actuating the Stabilizer Trim Switch on the control wheel affect auto flight?

Answer 14

-one switch nothing, if you actuate a pair together, it disconnects the autopilot.

Question 15

15. What is the purpose of the STAB TRIM switch on the Aft Electronic Panel?

Answer 15

-in OVERRIDE, it bypasses the control column actuated Stabilizer Tim Cutout Switches and restores power to the Stabilizer Trim Switches.

Question 16

16. What does the green band of the STAB TRIM indicator on the Control Stand indicate?

Answer 16

-Takeoff trim range

Question 17

17. What does an illuminated SPEED TRIM FAIL light (amber), during Master Caution Recall, indicate?

Answer 17

-a single FCC channel failure

Question 18

18. Describe the functions of the Stall Management Yaw Damper (SMYD) computers.

Answer 18

-collects inputs from ADIRUs, both control wheeel, and yaw damper switch, and then provides yaw damper input to Main Rudder PCU or Standby Rudder PCU to provide dutch roll prevention, gust damping and turn coordination.

Question 19

19. Which light is armed by selecting FLT CONTROL A or B switch to STBY RUD?

Answer 19

-the LOW PRESSURE light

Question 20

20. When does the Main Rudder Power Control Unit (PCU) limit full rudder authority?

Answer 20

-at speeds above 135 kts

Question 21

21. What does the Rudder Trim Control Switch do?

Answer 21

-electrically trims the rudder to the desired direction.

Question 22

22. How do you activate the Standby Yaw Damper?

Answer 22

-by placing both FLT CONTROL switches to STBY RUD

Question 23

23. What are the positions of the Speed Brake Lever, and what are the limitations?

Answer 23

-DOWN, ARMED, FLIGHT DETENT, and UP
-Do not move the speed brake lever beyond the flight detent in flight -Do not use speed brakes with up deployed
-Do not use speed brakes with less than 1000’ AGL

Question 24

24. What does the SPEED BRAKE DO NOT ARM light (amber) indicate?

Answer 24

-abnormal condition or abnormal test inputs to the Automatic Speed Brakes System

Question 25

25. During landing, when do the ground spoilers deploy?

Answer 25

-With speed brake lever armed and SPEED BRAKE ARMED light on, RA less than 10, both trust levers idle, and main landing gear wheels spin up (over 60 kts) or landing gear strut compresses on touchdown

Question 26

26. What would cause the LE FLAPS TRANSIT light (amber) to illuminate?

Answer 26

-any LE device in transit, and LE device not in programmed position with respect to TE flaps, a LE uncommanded motion condition exists (2 or more LE flaps or slats have moved from their commanded positions), or during alternate flap extension until LE devices are full extended and TE flaps reach flaps 15

Question 27

27. What is the normal position of the LE flaps for each FLAP lever position?

Answer 27

• LE slats in extended for TE flaps selection of 1, 2, 5, 10, 15, 25 -LE flaps to full extend
• TE flaps 30 and 40 the LE slats move to full extend.
  *non SFP - ext for 1, 2, 5, and full for 10, 15, 25, 30, and 40

Question 28

28. When do the LE slats deploy to FULL EXTEND?

Answer 28
