Q

How are the ailerons, elevators, and rudder actuated?

A

Yoke and pedals operate a system of cables and pulleys that connect to pull and push rods at the flight control which operate a hydraulic PCU (Power Control Unit) which hydraulically actuates the control surface.

Q

How are the MFSs controlled when used for roll assistance?

A

The FO’s yoke position sends an electrical signal to the left MFS panels which are hydraulically operated by PCU’s. The CA’s yoke position sends an electrical signal to the right MFS panel which are hydraulically operated by PCUs.

Q

What happens after the ROLL DISC handle is pulled?

A

The aileron cable and pulley systems are disconnected through torque tubes. 20 seconds later, if the operable side has not been selected, the amber ROL SEL switch/light illuminates.

Q

What is the flight deck indication of an aileron PCU runaway?

A

Aircraft begins an uncommanded roll and the PLT SEL switch/light on the side without the PCU runaway illuminates automatically because of the bungee break-out signal.

Q

How is the Yaw Damper engaged?

A

YD1 and YD2 engage switch/light on the center pedestal

18
Q

How is the Yaw Damper disengaged

A

DISC button on the center pedestal

19
Q

What controls the yaw damper?

A

The flight control computer (FCC)

20
Q

Is it necessary to disconnect the Yaw Damper on landing?

A

No

21
Q

How are the flaps operated?

A

Electrically

22
Q

How many flap segments does the CRJ have?

A

4 total, 2 on each wing

23
Q

Is there any asymmetrical protection within the flaps?

A

Yes, if the flap segments differ by more than 5 degrees, the brakes are applied and the flaps will remain in their current position

24
Q

How is STAB TRIM operated?

A

Electrically. A split switch on the control yoke operates two motors and a jack screw changing the horizontal stabilizer angle of incidence

25
Q

What systems can operate the STAB TRIM?

A

CA’s trim switches
FO’s trim switches
autopilot and MACH trim

26
Q

What is the priority for STAB TRIM control?

A

CA
FO
Autopilot
MACH trim

27
Q

What aids the crew in directional control during a jammed rudder condition?

A

Rudder system anti-jam/breakout mechanisms

28
Q

The purpose of aileron flutter dampers is:

A

To prevent control surface flutter when hydraulic power is lost to the PCU’s

29
Q

What are the takeoff flap settings?

A

8° and 20°

30
Q

The elevators, rudder, and ailerons are

A

manually controlled and hydraulically actuated

31
Q

What is the purpose of the Aileron Bungee Breakout Switch?

A

Provides automatic on-side MFS control to operable circuit during aileron PCU runaway

32
Q

Who/what has the highest priority when trimming the horizontal stabilizer trim?

A

Captain

33
Q

The horizontal stabilizer trim limits are

A

+2° to -13°

34
Q

A SPOILERONS ROLL caution message, accompanied by amber ROLL SEL lights on the glare shield indicates

A

Roll disconnect handle has been pulled, but spoileron priority has not been established

35
Q

What are the selectable flap positions?

A

0-1-8-20-30-45

36
Q

What message appears on EICAS if one flap motor fails?

A

Flaps HALFSPEED

37
Q

During landing or rejected takeoff, how does MFS deploy logic differ from the ground spoilers deploy logic?

A

MFS deployment requires R and L main landing gear WOW

38
Q

In the event of total AC electrical power failure, the flight controls will remain operational because ACMP 3B is powered by the ADG Bus

A

True

39
Q

Each elevator is hydraulically powered by ___PCU’s

A

3

40
Q

A clacker will activate when the horizontal stabilizer is in motion for

A

3 seconds
