Flight Controls

Question 1

What are the ailerons controlled by?

Answer 1

Power Control Units (PCU)

Question 2

What is manual reversion?

Answer 2

A loss of Hydraulic system A and B, pilots control wheel can move ailerons

Question 3

Can you use aileron trim with the autopilot engaged?

Answer 3

Prohibited

Question 4

At what point is spoiler deflection initiated?

Answer 4

Approx more than 10 degrees of control wheel displacement

Question 5

The horizontal stabilizer is controlled and positioned by:

Answer 5

A single electric trim motor

Question 6

During normal operations, which hydraulic system does the main yaw damper use?

Answer 6

Hydraulic system B

Question 7

When will the SPEED BRAKES EXTENDED light illuminate on flight?

Answer 7

When SPEED BRAKES are extended while in landing configuration( flaps more than flaps 10) or below 800 feet RA

Question 8

During landing, the auto speed brake system operates under what conditions?

Answer 8

SPEED BRAKE lever ARMED
SPEED BRAKE ARMED light illuminated
Thrust levers idle
Main landing gear wheel spin up ( more than 60 knots)
Landing gear strut compression
Radio altimeter less than 10 feet

Question 9

If speed brake lever is in DOWN position during landing or RTO, auto speed brake system works how?

Answer 9

Main landing gear wheel spin up (more than 60 knots)
Thrust levers idle
Reverse thrust levers positioned for reverse thrust

Question 10

On the ground, the SPEED RAKES EXTENDED light illuminates for what reason?

Answer 10

When speed brake lever is in the DOWN position and the ground spoilers are not stowed?

Question 11

Which hydraulic system normally operate flaps?

Answer 11

Hydraulic system B

Question 12

What are the normal flap position for landing?

Answer 12

15
30
40

Question 13

LE FLAPS TRANSIT light illuminates for what conditions?

Answer 13

Any LE device is in transit
LE device not in programmed position
ALE slat skew condition exists ( slats 2 through7)

Question 14

Flap load relief limits flap setting automatically for over speed conditions. What flap settings will flap load relief limit flaps?

Answer 14

Flap 30 and 40

From 40 to 30 if speed of 163 knots is exceeded

From 30 to 25 if 176 knots exceeded

Question 15

Which leading edge devices don’t have skew detection?

Answer 15

Slats 1 and 8
Leading edge flaps

Question 16

What happens when an uncommanded motion of the flaps slats is detected?

Answer 16

The TE drive unit is shutdown and the system will only operate in Alternate mode

Question 17

Moving the FLT CONTROL switch to STBY RUD does what?

Answer 17

Activates standby hydraulic system pump
Opens the standby rudder shutoff valve
Illuminates the STBY RUD ON light

Question 18

Which flight controls are mechanically controlled during manual reversion?

Answer 18

Ailerons
Elevator

Question 19

The yaw damper system is capable of providing what features?

Answer 19

Gust damping
Dutch roll prevention
Turn coordination

Question 20

Which hydraulic system controls yaw damper?

Answer 20

Hydraulic system B

Question 21

Slats will extend to the full extend position when what happens with flaps?

Answer 21

Flap lever is beyond flaps 5

Question 22

Flight Control Panel: FLIGHT CONTROL switches system A & B. What happens switch is in STBY RUD position?

Answer 22

Activates standby hydraulic system pump/ opens standby rudder shutoff valve to pressurize standby rudder power control unit (PCU)

Question 23

Flight Control Panel: FLIGHT CONTROL switches system A & B. What happens when switch is in off?

Answer 23

Closes flight control shutoff valve isolating ailerons, rudder, elevator from the associated hydraulic system pressure

Question 24

Flight Control Panel: FLIGHT CONTROL switches system A & B. What happens when switch in ON position?

Answer 24

Normal operating position

Question 25

Flight Control Panel: FLIGHT CONTROL system A & B LOW PRESSURE lights illuminate for what reasons?

Answer 25

• Indicates low hydraulic systems (A or B) pressure to ailerons, elevators, rudder
• Deactivated when associated FLIGHT CONTROL switch is positioned to STBY RUD and standby rudder shutoff valve opens
