25
what will happen if we have an automatic pitch trim differntial of 0.7 degrees or more?
PITCH TRIM ASYM caution AP will disconnect normal and standby pitch controls inhibited
26
what does the STBY pitch control switch do?
drives both electric motors of the trim actuators in he desired direction
27
how long does full pitch trim travel take?
30 seconds
28
what is full pitch trim deflection?
5 degrees up 1. degrees down
29
what does the pitch trim indicator represent?
position of the right pitch trim actuator
30
what does a yellow pitch trim pointer mean?
pitch assymetry detected pitch mistrim or pitch trim failure with autopilot engaged pointer outside green band before take off
31
wha does the green sector on the pitch trim indicator represent?
2.5 degrees up 0 degrees down
32
what will a trim outside the green on TO or during config test mean?
we get a master warning, chime and CONFIG on EWD
33
what does a magenta bug on the pitch trim indicator mean?
managed pitch trim target
34
which control column is the stick pusher connected to?
the captain
35
what does a stick pusher shaker button caution mean?
AOA probe disagreement power for stick pusher motor is lost
36
what activates the stick pusher?
MFC
37
what 5 components make up the yaw system?
1. travel limitation unit 2. trim actuator 3. releasable centering unit 4. rudder damper 5. yaw trim switches
38
how is the rudder controlled?
rudder pedals feeds to the spring tab autopilot feeds to the yaw actuator
39
what does the RCU do?
centres the rudder when no force is applied to the pedals
40
on the ground with no air load, what will the rudder spring tab do when the rudder reaches one of its stops?
it will move i the opposite direction
41
what does the spring tab do in the air?
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
what does the TLU do?
restricts rudder movement based on airspeed
43
how does the TLU work?
recievs data from ADC's and moves a fork to restrict rudder movement
44
in automatic mode, when will the TLU engage?
airspeed above 185 knots
45
in automatic mode, when will the TLU disengage?
airspeed below 180 knots
46
what will we see on the EWD when rudder travel is not limited by the TLU?
TLU LO SPEED
47
in auto mode, what data does the TLU use?
ADC information
48
what 5 things can cause a TLU FAULT?
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
what does the yaw damper do?
1. regulates rudder travel speed in flight 2. limits rudder movement on ground caused by wind
50
what powers the yaw trim motor?
DC EMER BUS
51
how long does full rudder trim travel take?
15 seconds
52
when is rudder trim inhibited?
when autopilot is enagaged
53
what does an amber rudder trim mean?
yaw mistrim auto trim failure with yaw damper engaged
54
when will the rudder centering unit (RCU) disengage?
when trimming
55
how are the outboard and inbaord flaps linked>
mechanically by a connecting pin and connecting rods
56
what can we see if the flap lever is out of detent?
amber strip on bottom of lever
57
what controls flap actuation?
4 flap actuators, through a flap control switch unit, MFC, and flap valve block
58
what does a cyan flap indication mena?
extension/retraction or flap position greater than 1 degree in disagreement
59
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
what are the inboard and outboard flaps connected by?
push pull rods
61
what minimises flap assymetry if the push pull rods fail?
a pin that connects the 2 panels
62
what does a red FLAP UNLK mean with a master warning?
flaps are extended and they retract more than 4 degrees uncommanded
63
how does the CAC sense a flap jam?
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
what prevents an excessive power setting when in hotel mode?
the gust lock
65
how are the ailerons locked with gust lock engaged?
electro mechanical locing device
66
how far past the neutral position can the ailerons be locked?
left or right 5 degrees
67
when will we get an amber AIL LOCK LIT
one of the locking actuators disagrees with the position of the gust lock
68
can the gust lock be put in with the controls in any position?
yes but the controls must be brought back to neutral to positively lock them
69
what powers the spoiler unlock lights?
DC BUS 1
70
what powers the normal pitch trim system?
DC EMER BUS
71
what powers STBY PITCH TRIM system?
DC BUS 2
72
what disables the stick shaker/pusher and stall audio aleert?
STICK PUSHER SHAKER button to off
73
what supplies stick pusher system power?
DC BUS 1
74
what powers the stick shakers?
DC BUS 1 and 2 to their respective sides
75
how can the TLU we controlled in the event of a fault?
by using hi speed or lo speed positions on the toggle switch
76
what powers the TLU system?
DC BUS 1
77
what powers yaw trim?
DC EMER BUS
