  1. How are the primary flight controls operated
    Mechanically
  2. How are the Trims operated
    Electronically
  3. How are the Flaps operated
    Hydraulically
  4. What joins the ailerons together
    Aileron Interconnect unit
  5. Which side aileron trim is operated when the main trim is used
    Left side
  6. Which side aileron trim is operated if the Standby Trim is used
    Right side
  7. What makes up the Interconnect unit
    A friction device to hold the two ailerons together
  8. How can the ailerons be reconnected after the roll disconnect has been pulled
    Only by ground maintenance on the ground
  9. How are the two elevators joined together
    Elevator Interconnect unit 
  10. Which elevator trim moves when the yoke mounted trim switch is moved
    Both main and standby when PITCH TRIM is synched
  11. What allows the main and standby trims to operate together
    The pitch trim synchronizer
  12. How are the Main and Standby trims separated from each other
    By operating the Standby trim switch
  13. How are the main and Standby trims tied together
    Pitch trim synchronizer
  14. If the left control wheel trim switch is operated and the right wheel switch operated in the other direction how do the trims respond
    The Captain's trim will override the FO's trim
  15. When would you get a CONFIG CWP light
    • During T/O when:
    • Pitch trims are out of takeoff range, "green arc"
    • Condition levers not at Max
    • Flaps are beyond 15 degrees 
  16. If takeoff is attempted with the trims outside of the green arc what happens
    Master Warning, CONFIG CWP, and Intermittent Horn
  17. A stall warning is provided by what simultaneous indications
    • An Aural Clacker
    • A Stick Shaker 
  18. At Stall Threshold what happens
    The Stick Pusher Activates 
  19. How much pressure does the Stick Pusher generate
    80 lbs of force
  20. What lights will illuminate as the Stick Pusher activates
    PUSH 1 and PUSH 2 on both sides of the panel
  21. How is the Stick Pusher Overridden
    By overpowering the 80 lbs of force
  22. What are the 3 warning signs of a stall
    Stick shaker, clacker, and push lights
  23. How is the Stick Pusher deactivated
    Reduce the Angle of Attack
  24. What is being checked when the stall test switches are both pushed down
    The .5g sensor is functioning properly, and the pusher does not activate
  25. When testing the stall system what is being checked
    • Associated PUSH light illuminates
    • Aural alert (clacker)
    • Stick shaker
    • With both switches up stick pusher activates along with PUSH 1 and PUSH 2
    • With both switches down pusher does not activate with PUSH 1 and PUSH 2
  26. How can the Pusher System be reset after deactivation
    Only by maintenance
  27. When is the Stick Pusher inhibited
    • While on the ground
    • After takeoff for 7 seconds
    • Anytime load factor is less than .5g 
  28. What angle does the Stick Pusher move the elevator to
    4 degrees nose down
  29. How long is the Stick pusher sustained for
    • As long as the excessive AOA exists
    • Load Factor less than .5g 
  30. What does a STALL FAIL CWP light indicate
    A fault detected in a stall warning/ ident computer
  31. What is the purpose of the Rudder Limiter
    To limit rudder travel at high airspeeds
  32. What are the speed and travel limits of the Rudder Limit system
    • Full travel (up to 30 degrees) at speeds up to 150 knots
    • Intermediate travel (up to 15 degrees) at speeds between 150-200 knots
    • Minimum travel (up to 5.7 degrees) at speeds above 200 knots
  33. What does a RUDDER LIMIT CWP light indicate
    Discrepancies between monitored Airspeeds or an improperly positioned limiting mechanism
  34. What is the purpose of the RUD LIM switch
    In OVRD, allows full rudder travel by retracting rudder limiting mechanism
  35. What is 'Flap blow-back'
    A design feature that allows the flaps to retract at excessive airspeeds in order to prevent flap damage
  36. Are the flaps operated as a single unit
    No, they are 2 individual flaps operated by a single HYDR actuator unit
  37. What keeps the flaps from a split flap condition
    A mechanical interconnection
  38. What are the flap detent settings
    0, 7, 15, 20, and 35 degrees
  39. What is indicated by an illuminated FLAPS CWP light
    Failure of the flap controller
  40. Does a split flap automatically trigger a FLAPS CWP light
    No, if the left flap aggrees then no light
  41. If the flap controller fails what are the indications
    • FLAPS CWP light
    • Master Caution
    • Flaps become locked in position without further control 
  42. What a flap controller failure how could the crew verify flap position
    By use of the flap angle marks on the flap
  43. At what settings are the gates located druing flap retraction 
    7 and 20 degrees
  44. What position do the Gust locks fail to
    Unlocked
  45. How do the GUST LOCKS prohibit Takeoff while engaged
    Power lever movement is limited
  46. When would you get a GUST LOCK CWP light
    When the Gust Lock is released and the rudder fails to unlock
  47. Are the aileron and elevator gust locks electric or mechanical
    Mechanical
  48. Is the Rudder gust lock electric or mechanical
    Electric
  49. How are the trim switches operated
    Both switches must be moved together
