Flight Controls Flashcards
What is the only primary flight control that is not FBW?
Ailerons
What is the difference between normal mode and direct mode?
There are no higher level functions available in direct mode
What are the higher level functions associated with pitch?
Gain on airspeed
Elevator thrust compensation
AoA limiting
What are the higher level functions associated with yaw?
Yaw damp
Turn coordination
Thrust asymmetry
Gain on airspeed
What is the priority for the trim system?
Back-up
Captain
First officer
Autopilot
How is roll controlled?
Ailerons and multi-function spoilers (outer 3 on each wing)
How many multi-function spoilers are on each wing? What are their functions?
5 total
3 outboard spoilers are used to assist in roll control and for ground spoilers
2 inboard are only used as ground spoilers
When will the speed brakes automatically close even if the lever shows deployed?
Flaps > 2
Airspeed > 180 kts
TLA > 70 deg
What is the flap/slat extension/retraction sequence?
Slats before flaps - extension
Flaps before slats - retraction
Will loss of airspeed data cause the flight controls to go into direct mode?
Yes
Can a FCM override pilot input?
No, the pilot always has supreme control?
What happens to artificial feel if flight controls are disconnected?
Artificial feel is felt at 1/2 the normal load
How are the flight controls trimmed?
Ailerons and rudder repositioned to new neutral position
Horizontal stab moves for pitch
Will the multi function spoilers function in direct mode?
Yes, for roll only and at a default fixed gain
Will the speed brakes/ground spoilers function in direct mode?
No
