Q

What maybe indicated when the aileron lockout light comes on while accelerating?

A

One or both of the outboard ailerons failed to lock out

21
Q

Why should the speed brake lever be moved from ARMED to the DOWN detent if the AUTO SPDBRK light illuminates?

A

To prevent inadvertent speed brake extension in flight. Speed brakes must be manually deployed upon landing

22
Q

What is the function of the rudder ratio system?

A

Decreases maximum rudder pedal inputs from the pilot to reduce rudder deflection with increasing air speed

23
Q

Which hydraulically powered rudder actuator is automatically depressurised when the RUDDER RATIO light is illuminated?

A

Left

24
Q

What is indicated by an illuminated SPOILERS light and SPOILERS EICAS message?

A

One or more spoiler panels has failed to operate

25
Q

Which hydraulic systems power the left and right yaw dampers respectively?

A

Centre and left

26
Q

What action can be taken to possibly regain full stabiliser trim rate when the stab trim light illuminated?

A

Trim with alternate stabiliser trim

27
Q

What systems must be available to the yaw dampers to pass yaw damper test?

A

One aligned IRS and hydraulic power for the system tested

28
Q

During normal operation, at what flap position do the leading edge slats extend to the landing position?

A

25

29
Q

What is indicated by the UNSCHED STAB TRIM light?

A

Stabiliser movement without a trim signal (possible trim run away) or the stabiliser is being trimmed in the opposite direction to the autopilot

30
Q

What overrides all other stabiliser trim systems inputs?

A

Alternate stabiliser trim switches

31
Q

What is the stabiliser trim rate during autopilot operation?

A

Half the electric trim rate

32
Q

How can stabiliser movement be stopped if a trim run away is detected?

A

Move the control column in the opposite trim direction

33
Q

What does the RUDDER RATIO light illuminated in-flight mean?

A

Control inputs to the rudder are not being correctly modified. Limited import should be used

34
Q

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

A

Fault exists in the system

35
Q

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

A

The alternate system operates the flaps with electric motors

36
Q

Is normal flap load relief available while utilising the alternate flaps system?

A

No

37
Q

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

A

Only the leading edge slats extend

38
Q

On an aircraft with winglets, when does the speed brake load alleviation system activate?

A

Flaps up,
Aircraft weight is above 340,000lbs
Airspeed is greater than 320 knots

39
Q

The pitch enhancement system operates when?

A

Operates automatically with the loss of centre and left hydraulic system pressure

40
Q

An off flag in the stabiliser position indicator means?

A

Stabiliser trim indicator failure

41
Q

What happens when take off power is applied and stab trim is out of the green band?

A

CONFIG warning light illuminates
EICAS stabiliser warning appears
Master warning light illuminates
Siren sounds

42
Q

What do the STAB TRIM CUTOUT switches do when placed to the CUTOUT position?

A

Remove electrical power to the stab trim
Shut off respective hydraulic power to the stab trim
Enables use of manual or alternate trim switches

43
Q

How are the control wheel stabiliser trim switches affected when multiple autopilots are engaged, as in autoland?

A

They are inhibited

44
Q

The pitch enhancement system (PES) is an automatic feature to provide a third power source for stabiliser trim in the event what system fails?

A

Left and centre hydraulic systems

45
Q

At higher airspeeds which wing components are locked out?

A

Outboard ailerons

46
Q

What is indicated when the aileron lockout light comes on at low airspeeds?

A

One or both of the outboard ailerons failed to unlock

47
Q

What is/are the normal landing flap setting(s)?

A

Flaps 25 and 30

48
Q

Is there any asymmetry protection in alternate flap mode?

A

Trailing edge flap protection is not available in alternate mode
