Q

What is indicated by STAB TRIM light during electrical trimming?

A

Only one stabilizer brake failed to release

28
Q

What is the electric stab trim rate with the STAB TRIM light illuminated?

A

1/2 of normal rate

29
Q

When are flight control shutoff switches used?

A

Ground use only

30
Q

What systems must be available to the Yaw Dampers to pass a yaw damper test?

A

One aligned IRS and hydraulic power for the system tested

31
Q

What EICAS page displays the rudder, aileron and elevator position?

A

Status

32
Q

Which trailing edge flap drive systems have asymmetry protection?

A

Only normal

33
Q

Which of the following are indicated by the UNSCHED STAB TRIM light?

A

Stabilizer movement without a trim signal

34
Q

When the stabilizer moves in the opposite direction signalled by the autopilot, the UNSCHED STAB TRIM light illuminates.

A

True

35
Q

Which hydraulic system loss prevents auto speedbrake deployment?

A

CENTRE

36
Q

How many hydraulic actuators are used for each elevator?

A

Three

37
Q

What is the stab trim rate during autopilot operation?

A

1/2 the electric trim rate

38
Q

How can stabilizer movement be stopped?

A

Move the control column in the direction opposing trim

39
Q

How many hydraulic system(s) provide hydraulic power for the rudder?

A

Three

40
Q

From where is airspeed data for the ratio changer received?

A

Air Data Computer (ADC)

41
Q

What does RUDDER RATIO light illuminated inflight mean?

A

Control inputs to the rudder are not being correctly modified

42
Q

What is indicated when the LEFT Yaw Damper switch is OFF and the INOP light is illuminated?

A

The system has been turned off manually

43
Q

What is indicated when the right yaw damper switch has an ON indication and the INOP light is illuminated?

A

A fault exists in the system

44
Q

How many actuators on each aileron panel position the ailerons?

A

Two

45
Q

How many spoilers panels are there on each wing?

A

Six

46
Q

When will the speedbrakes extend automatically, after landing, if the speedbrake lever is not armed?

A

Will deploy when either reverse thrust lever is moved to the interlock stop

47
Q

What is indicated by the AUTO SPDBRK light when the system is armed?

A

A fault exists which may cause an inflight extension

48
Q

How are the flaps operated after a CENTRE hydraulic system failure?

A

The alternate system operates the flaps with electric motors

49
Q

How long does the alternate flap extension system require to extend the flaps and slats from UP to the 20 position?

A

Approximately 3 minutes

50
Q

Which ailerons lock out at speeds above approximately 280 kts?

A

Outboard ailerons

51
Q

Which hydraulic system supplies power to the flaps and slats?

A

Centre

52
Q

What conditions are necessary for the speed brakes to extend automatically at touchdown?

A

53
Q

At which flaps setting do the leading edge slats move to the fully extended position?

A

Position 25 (At any setting past flaps 20…)

54
Q

For the speedbrakes to extend automatically during a RTO, the Speedbrake lever must be positioned to ARMED

A

False

55
Q

What happens when moving the flap lever from UP to the 1 position?

A

Only the leading edge slats extend

56
Q

Before you land, ‘AUTO SPEEDBRAKE’ EICAS message appears. What is the result?

A

The speedbrakes do not extend automatically upon landing

57
Q

What inflight restrictions result from the loss of both yaw dampers?

A

No inflight restrictions apply

58
Q

Do the rudder pedals move with rudder trim inputs?

A

Yes

59
Q

Do the rudder pedals move with yaw damper inputs?

A

No

60
Q

In normal operations, which hydraulic systems supply power to the horizontal stabilizer trim modules?

A

Left and Centre

61
Q

When do the leading edge slats move to the fully extended position?

A

At any setting past flaps 20

62
Q

How does the alternate flap/slat system differ from the normal flap/slat system?
