18. Air Line Pilots Association, International What is the purpose of the tuning backup control head (TBCH)?

19. Air Line Pilots Association, International It is a backup means by which to tune COM#2 and NAV#2 if the RMU is inoperative.

20. Air Line Pilots Association, International What is being checked when the TO CONFIG Button is pressed?

21. Air Line Pilots Association, International ► Spoilers closed ► Parking brake off ► Pitch trim in green range ► Flaps not set for takeoff

22. Air Line Pilots Association, International What conditions must be met in order for the ground spoilers to deploy?

23. Air Line Pilots Association, International ► Aircraft on ground ► Thrust levers retarded ► Wheel speed above 25 kts.

24. Air Line Pilots Association, International What conditions must be met in order for the speed brakes to deploy?

25. Air Line Pilots Association, International ► Flaps 0 ⁰ or 9 ⁰ ► Thrust levers retarded ► Speed brake lever OPEN

26. Air Line Pilots Association, International What might be the reason for a speed brake lever disagree caution message on the EICAS?

27. Air Line Pilots Association, International ► The speed brake lever is OPEN with either the thrust levers advanced or the flaps set above 9 o ► The speed brake lever is CLOSED and the aircraft is taxiing faster than 25 kts.

28. Air Line Pilots Association, International How many emergency brake actuations are available with the emergency brake accumulator?

29. Air Line Pilots Association, International 6.

30. Air Line Pilots Association, International How many emergency brake actuations are remaining if the EMERG BRK LO PRESS caution message is presented on the EICAS?

31. Air Line Pilots Association, International 1.

32. Air Line Pilots Association, International How long will the pressure last in the parking brake accumulator?

33. Air Line Pilots Association, International 24 hours.

34. Air Line Pilots Association, International What flight director guidance is provided when the go-around buttons are pushed?

35. Air Line Pilots Association, International ROL GA mode commanding a pitch attitude of 10 ⁰, then; ROL IAS mode commanding 170 knots, then; ROL IAS mode commanding the blue airspeed bug if unable 170 knots.

36. Air Line Pilots Association, International What effect does pressing the go-around buttons have on the FMS during an approach?

37. Air Line Pilots Association, International The missed approach segment is sequenced in the FMS.

38. Air Line Pilots Association, International When will the stall protection test light be illuminated?

39. Air Line Pilots Association, International ► After initial power up ► After an unsuccessful test

40. Air Line Pilots Association, International How often must the stall protection system be performed?

41. Air Line Pilots Association, International Before every flight.

42. Air Line Pilots Association, International What systems are lost if one of the stall protection cutout buttons are pressed?

43. Air Line Pilots Association, International The stickpusher.

44. Air Line Pilots Association, International What would be disabled if you pressed the main pitch trim cutout button?

45. Air Line Pilots Association, International ► Main trim switches on yoke ► Autopilot ► Speed brake auto-trim

46. Air Line Pilots Association, International When the roll control knob is turned, what lateral mode is entered?

47. Air Line Pilots Association, International ROL mode.

48. Air Line Pilots Association, International Can a heading be selected when the ROLL knob is not centered?

49. Air Line Pilots Association, International No.

50. Air Line Pilots Association, International What happens when the DUMP button on the auto pressure controller is pressed?

51. Air Line Pilots Association, International Both outflow valves open and cause a rapid decompression. The DUMP button only works in AUTO mode.

52. Air Line Pilots Association, International How many outflow valves are active in the AUTO mode?

53. Air Line Pilots Association, International Two. The electo-pneumatic outflow valve is commanded by the auto pressure controller and the pneumatic outflow valve is slaved to follow it.

54. Air Line Pilots Association, International How many outflow valves are active in the manual mode?

55. Air Line Pilots Association, International One. The pneumatic outflow valve.

56. Air Line Pilots Association, International What might happen if the manual selector knob on the pressurization panel is not in the DN position while in the AUTO mode?

57. Air Line Pilots Association, International The pneumatic outflow valve could unslave from the electro- pneumatic outflow valve.

58. Air Line Pilots Association, International How would you know if the auto pressurization system completed a successful power up test?

59. Air Line Pilots Association, International “8888” would be displayed in the digital display until a landing altitude was entered.

60. Air Line Pilots Association, International What happens if a landing field elevation is not entered (after initial power- up) into the auto pressurization controller?

61. Air Line Pilots Association, International The system assumes an 8000 ft landing elevation.

62. Air Line Pilots Association, International If it became necessary to return to the departure airport, would it be necessary to enter its field elevation?

63. Air Line Pilots Association, International No. The cabin altitude is kept at the departure airport field elevation until the theoretical cabin altitude increases, up to 15 minutes.
