32
Q

what will a trim outside the green on TO or during config test mean?

A

we get a master warning, chime and CONFIG on EWD

33
Q

what does a magenta bug on the pitch trim indicator mean?

A

managed pitch trim target

34
Q

which control column is the stick pusher connected to?

A

the captain

35
Q

what does a stick pusher shaker button caution mean?

A

AOA probe disagreement

power for stick pusher motor is lost

36
Q

what activates the stick pusher?

A

MFC

37
Q

what 5 components make up the yaw system?

A
  1. travel limitation unit
  2. trim actuator
  3. releasable centering unit
  4. rudder damper
  5. yaw trim switches
38
Q

how is the rudder controlled?

A

rudder pedals feeds to the spring tab

autopilot feeds to the yaw actuator

39
Q

what does the RCU do?

A

centres the rudder when no force is applied to the pedals

40
Q

on the ground with no air load, what will the rudder spring tab do when the rudder reaches one of its stops?

A

it will move i the opposite direction

41
Q

what does the spring tab do in the air?

A

moves in the opposite direction to the rudder when it reaches the stop in order to reduce pilot workload.

its deflection increases with airspeed

42
Q

what does the TLU do?

A

restricts rudder movement based on airspeed

43
Q

how does the TLU work?

A

recievs data from ADC’s and moves a fork to restrict rudder movement

44
Q

in automatic mode, when will the TLU engage?

A

airspeed above 185 knots

45
Q

in automatic mode, when will the TLU disengage?

A

airspeed below 180 knots

46
Q

what will we see on the EWD when rudder travel is not limited by the TLU?

A

TLU LO SPEED

47
Q

in auto mode, what data does the TLU use?

A

ADC information

48
Q

what 5 things can cause a TLU FAULT?

A
  1. limiting fork position disagreement
  2. dual ADC failure
  3. airspeed data disagreement
  4. TLU position synchronisation failure
  5. multiple failures in the CAC
49
Q

what does the yaw damper do?

A
  1. regulates rudder travel speed in flight
  2. limits rudder movement on ground caused by wind
50
Q

what powers the yaw trim motor?

A

DC EMER BUS

51
Q

how long does full rudder trim travel take?

A

15 seconds

52

53
Q

what does an amber rudder trim mean?

yaw mistrim

auto trim failure with yaw damper engaged

54
Q

when will the rudder centering unit (RCU) disengage?

A

when trimming

55
Q

how are the outboard and inbaord flaps linked>

A

mechanically by a connecting pin and connecting rods

56
Q

what can we see if the flap lever is out of detent?

A

amber strip on bottom of lever

57
Q

what controls flap actuation?

58
Q

what does a cyan flap indication mena?

A

extension/retraction or flap position greater than 1 degree in disagreement

59
Q

when will flaps become inoperative?

if difference in flap setting exceeds 6.7 degrees as as sensed by the MFC. this can only be reset on the ground

60

push pull rods

61
Q

what minimises flap assymetry if the push pull rods fail?

A

a pin that connects the 2 panels

62
Q

what does a red FLAP UNLK mean with a master warning?

A

flaps are extended and they retract more than 4 degrees uncommanded

63
Q

how does the CAC sense a flap jam?

A

takes the average left and right position and if this is more than 1 degree out for more than 30 secs it will create an amber FLAPS JAM

64
Q

what prevents an excessive power setting when in hotel mode?

A

the gust lock

65
Q

how are the ailerons locked with gust lock engaged?

A

electro mechanical locing device

66
Q

how far past the neutral position can the ailerons be locked?

A

left or right 5 degrees

67
Q

when will we get an amber AIL LOCK LIT

A

one of the locking actuators disagrees with the position of the gust lock

68
Q

can the gust lock be put in with the controls in any position?

A

yes but the controls must be brought back to neutral to positively lock them

69
Q

what powers the spoiler unlock lights?

A

DC BUS 1

70
Q

what powers the normal pitch trim system?

A

DC EMER BUS

71
Q

what powers STBY PITCH TRIM system?

A

DC BUS 2

72
Q

what disables the stick shaker/pusher and stall audio aleert?

A

STICK PUSHER SHAKER button to off

73
Q

what supplies stick pusher system power?

A

DC BUS 1

74
Q

what powers the stick shakers?

A

DC BUS 1 and 2 to their respective sides

75
Q

how can the TLU we controlled in the event of a fault?

A

by using hi speed or lo speed positions on the toggle switch

76
Q

what powers the TLU system?

A

DC BUS 1

77
Q

what powers yaw trim?

A

DC EMER BUS
