Flashcards in Flight Controls Deck (26):
0

Which yoke is connected to the right aileron?

FO

1

Which yoke is connected to the left aileron?

Captain's

2

How are the ailerons, elevators and rudder actuated?

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 which hydraulically actuated the control surface

3

Which yoke controls the right elevator?

FO

4

Which yoke controls the left elevator?

Captain's

5

What is the purpose of the multifunction Spoilers (MFS)?

To assist with roll control and serve as a spoiler in flight and on landing

6

Are the MFS operational at any speeds?

Yes

7

How are the MFS's controlled when used for roll assistance?

The FO's yoke position sends and 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 panels which are hydraulically operated by PCU's.

8

What is the flight deck indication of a jammed aileron cable?

Both yokes will be jammed

9

What happens after the ROLL DISC handle is pulled?

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 SWITCHLIGHT illuminates

10

How is the operable side (roll) selected?

By pushing the ROL SEL/PLT ROL SWITCHLIGHT on the unjammed side

11

What does pushing the ROL SEL/PLT ROL SWITCHLIGHT accomplish?

Allows the pilot with the operable aileron to control the on-side MFS panels

12

What is flight deck indication of an aileron PCU runaway?

Aircraft begins an uncommand roll and PLT SEL SWITCHLIGHT on the side without the PCU runaway illuminates automatically because of the bungee break-out signal

13

What is occurring when the pilots trim the aileron or rudder?

The control surface is being repositioned
There are no trim tabs

14

What panels are part of the GND LIFT dumping system?

Inboard and outboard ground spoilers
All 4 MFS panels

15

How are the flight controls gust locked?

Hydraulic fluid is trapped after shutdown

16

How is the Yaw Damper engaged?

YD1 and YD2 engage SWITCHLIGHT on the center pedestals

17

How is the YD disengaged?

DISC button on the center pedstal

18

What controls the YD?

The flight control computer

19

Is it necessary to disconnect the YD on landing?

No

20

How are the flaps operated?

Electrically

21

How many flap segments does then CRJ have?

4 total, 2 on each wing

22

Is there any asymmetrical protection within the flaps?

Yes, if the flap segments differ by >5 degrees
The brakes are applied and the flaps will remain at the current position

23

How is STAB TRIM operated?

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

24

What systems can operate the STAB TRIM?

CA & FO trim switches
Autopilot and MACH trim

25

What is the priority for STAB TRIM control?

CA
FO
Autopilot
MACH trim
