Q

What is the rudder travel limiter?

A

The rudder travel limiter restricts rudder movement to prevent excessive tail loading at high speeds. It receives airspeed inputs from the Air Data Computers, and the Slat/Flap Electronic Control Unit. Rudder travel will be restricted from 33º to 4º based on flap position and speed.

Q

When the PITCH DISC handle is pulled, will the autopilot be available? Why?

A

The autopilot may not be available because the autopilot servo for pitch control is located on the Captain’s side.

Q

When the ROLL DISC handle has been pulled, what roll control surfaces will each yoke have control of?

A

The left yoke controls the left aileron, and the right yoke controls the right aileron. Each yoke controls the opposite side’s multifunction spoilers.

Q

If the rudder is jammed, how can control be regained?

A

Increasing the pressure on the rudder pedals will cause the bungee breakout system to be activated and control can be regained.

Q

How many stab trim motors are active at a time?

A

Only one motor drives the jackscrew at a time. The other motor free wheels with the operative mnotor, and assumes control if the operating motor fails.

17
Q

Will the autopilot disengage if manual control yoke trim is used?

A

Yes.

18
Q

Name the four different trims in order of priority.

A
  • Manual Yoke Trim
  • Autopilot Trim
  • Auto Trim (flap compensation)
  • Mach Trim
19
Q

What protection is provided in the event of a stab trim runaway?

A

Stab trim brakes controlled by the SSCUs.

20
Q

What is auto trim?

A

Auto trim compensates for changes in aircraft pitch associated with flap extension and retraction. It is also known as Flap Compensation Trim.

21
Q

What is the purpose of the split switch on the control yoke for stab trim?

A

Both halves of the switch must be moved together to engage the trim motors. If one half of the switch jams the trim motors will not run.

22
Q

Will the alternate flap extension switch move the slats and flaps while flying faster than 230 KIAS?

A

No.

23
Q

Will the alternate flap extension switch override the position of the flap handle?

A

Yes.

24
Q

Will the stick pusher engage if only one switch is armed?

A

No.

25
Q

If the ground spoilers fail the deploy after touchdown, what action can be taken?

A

Move the GND LIFT DUMPING switch to MAN ARM.

26
Q

How is hydraulic pump 3B powered in the event of a total electrical failure?

A

The ADG.

27
Q

What protects the ailerons from flutter in the event of a loss of pressure to the PCUs?

A

Flutter dampers.

28
Q

What protects the flight controls in the event of a PCU runaway?

A

Bungee Breakouts.

29
Q

What are the slats and flaps powered by?

A

Two electric motors, each controlled by two Slat/Flap Electronic Control Units. (SFECUs)

30
Q

What happens if one slat or flap motor fails?

A

The slats or flaps will operate at half speed.

31
Q

What is the elevator travel?

A

23º up and 18º down.

32
Q

Where is rudder or aileron mistrim indicated?

A

It will be indicated as a boxed R or A on the PFD.

33
Q

When do the spoilers retract after landing?

A

Forty seconds after weight on wheels.

34
Q

Stall protection angle of attack trip points result in progressive automatic warnings. What are they?

A

Continuous Ignition, autopilot disengages, shaker, pusher, glareshield lights, and finally the audio warbler.

35
Q

What does the GLD UNSAFE caution message indicate?

A

It indicates ground lift dumping may occur inadvertently if the system is not manually disarmed.
