Flight Controls

Question 1

Normal and direct mode

Answer 1

There are no higher lever functions available in direct mode

Question 2

What are the higher level functions associated with pitch?

Answer 2

Gain airspeed

Elevator thrust compensation

AOA limiting

Question 3

What is connected to gear box?

Answer 3

F.      FUEL PUMP
I.       IDG
S.     STARTER (air turbine starter)
H.     Hydraulic Pump
O.     Oil pump
I
L
         PMA

Question 4

What are the higher level functions associated with yaw?

Answer 4

Yaw damp

Turn coordination

Thrust asymmetry

Gain on airspeed - as airspeed increases, rudder deflection decreases

Question 5

Not fly by wire

Answer 5

Ailerons

Question 6

What is the priority for the trim system?

Answer 6

Backup

Captain

First Officer

Autopilot

Question 7

How is roll controlled ?

Answer 7

Ailerons and multi-function spoilers

Outer 3 spoilers on each wing

Question 8

How many multifunction spoilers are on each wing?

What are their functions?

Answer 8

5

3 outboard spoilers are used to assist in roll control and for ground spoilers

2 inboard spoilers are only used for ground spoilers

Question 9

Oral

When will the speed brakes automatically close even if the lever shows deployed?

Answer 9

Flaps >2

Airspeed 70 degrees

Question 10

What is the flap/slat extension/retraction sequence?

Answer 10

Slats extend first

Flaps extend first

Question 11

What is the priority for the trim system?

Answer 11

Backup
Captain
First Officer
Autopilot

Question 12

How is roll controlled?

Answer 12

Ailerons and multifunction spoilers (outer 3 spoilers on each wing )

Question 13

Will loss of airspeed data cause the flight controls to go into direct mode?

Answer 13

Yes

Question 14

Can a FCM override a pilot input?

Answer 14

No, the pilot always has supreme control

Question 15

What happens to artificial feel if flight controls are disconnected?

Answer 15

Artificial feel is felt at 1/2 the normal load

Question 16

How are the flight controlls trimmed?

Answer 16

Roll and Yaw. – ailerons and rudder surface repositioned to a new ‘neutral position’

Pitch. – horizontal stabilizer

Question 17

Will the-multi function spoilers function in direct mode?

Answer 17

Yes, for roll only and at a defaulted fixed gain

Question 18

Will the speed brakes/ ground spoilers function in ‘ direct’ mode?

Answer 18

No

Question 19

What happens to the to the flight control system when the RAT is the only AC power source?

Answer 19

Horizontal stab trim operates at 1/2 speed?

Slat / flap system operates 1/2 speed?

Slat / flap position is limited to ‘3’ to allow adequate airspeed for the RAT

Question 20

What is the only primary flight control that is not FBW (Fly By Wire)?

Answer 20

Ailerons
