  22. What are the limitations with flight spoiler use?
    Not below 500 ft AGL, VREF +8, no emer spoilers unless emergency conditions or directed by procedure
  23. Which flight control does the left yoke operate when pulling the roll disconnect?
    The left yoke controls the multifunction spoilers only
  24. What is the memory item for Roll/Yaw Axis Uncommanded Motion?
    1. Master Disconnect Switch…..Depress and hold
  25. Can the autopilot be engaged independently from the yaw damper?
    No
  26. Do both ailerons have trim tabs?
    No, just the left aileron
  27. What are the memory item(s) for Overspeed?
    • 1. Thrust levers…….IDLE
    • 2. Autopilot……Disconnect
    • 3. FLIGHT SPOILERS……EMER
    • 4. Level wings, then pitch up
  28. Which trim, primary or secondary, trims faster at cruise?
    Secondary trim
  29. Which flight computer controls the outboard flight spoilers?
    SECU 2
  30. For approximately how long do the PCUs provide rudder dampening against gust loads after hydraulic pressure is removed?
    12 hr
  31. Which spoilers are used for lift dumping?
    • Panel 1 and 8 in MAX
    • and 2 and 7 in EMER
  32. In what situation are ALT flaps needed?
    Right hydraulic pressure loss or when directed by procedure
  33. Which spoiler panels move on the ground?
    All of them
  34. Normal flap extention from 0 to 30 should not exceed what time limit?
    25 seconds
  35. The primary trim has which function(s) that the secondary trim does not have?
    Autopilot, configuration trim, variable speed trim, and Mach trim
  36. If the Mach trim is inoperative and the autopilot is engaged, is speed limited?
    No
  37. What result does the calculated trim setting achieve?
    Trimmed for V2
  38. Where are the spoiler RVDTs located?
    Inside both yokes
  39. Do PRI and SEC trim travel at the same rate?
    No. Primary trim adjusts according to speed, and secondary trim rate is a constant 0.2° per second.
