Q

If a TE condition is corrected after switch to secondary mode, when will a flap group switch back to primary mode?

Q

What do the shearouts do?

A

Allow pilots to regain control in the event of a jam.

20
Q

What power elevator feel?

A

Hydraulic system 2 and 3

21
Q

What is provides elevator feel in the event of HYD system 2 and 3 fail?

A

a mechanical spring

22
Q

Can the trim be manually moved with the AP engaged?

A

Yes, by the alternate trim switches

23
Q

The Elevator Feel System ________ forces to move the column at increased airspeeds.

A

Increase

24
Q

The two pairs of manual stabilizer trim switches are located on the ___________ and the ____________.

A

Control wheel , control stand

25
Q

Moving the appropriate STAB TRIM CUT OUT switch to the CUTOUT position does what?

A

Deactivates associated hydraulic power to the STCM, and the associated STAB TRIM 2 or 3 displays

26
Q

What does the aileron lockout do?

A

Locks the outboard ailerons at high speed

27
Q

What controls roll control with spoilers extended?

A

The spoiler mixer

28
Q

How does the aileron jam override mechanism function?

A

By application of higher than normal force

29
Q

Can you trim the ailerons when the AP is engaged?

A

NO

30
Q

Only the ______ side spoiler indicator indicates speedbrake operation, on the Flight Control Synoptic Display.

A

Left

31
Q

What protection does the rudder ratio changer provide?

A

Limiting rudder pedal displacement to protect the vertical structure

32
Q

What happens when a rudder ratio changer fails?

A

The rudder pedal inputs remain the same as when the failure occurred

33
Q

What is the risk associated with the a rudder stuck in a high speed condition? Low speed condition?

A

Limited range, reduced crosswind landing capabilities
Too much range, risk damage to the vertical structure

34
Q

What powers the yaw damper?

A

Upper System 3
Lower System 2

35
Q

T/F: Yaw Damper operation can be viewed on the Flight Control Synoptic display

A

False

36
Q

T/F: If a rudder ratio changer fails, the response of the associated rudder panel to the rudder inputs remains the same as when the failure occured, regardless of the current airspeed.

A

True

37
Q

How many spoiler panels are on each wing?

A

6

38
Q

How many spoiler panels extend in flight?

A

4

39
Q

What happens if one spoiler panel fails?

A

The symmetrical panel is shut down

40
Q

What is required for the ground spoilers to deploy?

A

Main gear touch down and engine 1 and 3 forward thrust levers are retarded

41
Q

How does the spoiler flight detent extend the spoilers?

A

Inboard to mid-travel
Mid to full travel

42
Q

When will “>SPEEDBRAKES EXT” message display?

A
  • above 15’ RA and below 800’ RA, or
  • the flaps are set for landing, or
  • two or more thrust levers are forward of the idle position
43
Q

When will ground spoiler deploy when not armed?

A

In an RTO and Landing, when 2 or 4 TRs is raised to idle with engine 1 and 3 forward thrust levers are retarded

44
Q

When will the ground spoilers retract after deployment?

A

If thrust lever 1 or 3 is moved out of idle or they can be manually moved

45
Q

For roll augmentation, the 5 most ________ spoilers receive control inputs from the spoiler mixing system.

A

Outboard
