Study Guide Flight Controls Flashcards
What is he only primary flight control that is not FBW (Fly-By-Wire)?
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
- Gain on airspeed
What is the priority of the trim system?
- Backup
- Captain
- First Officer
- Autopilot
How is roll controlled?
Ailerons and multi-function spoilers (outer 3 spoilers on each wing)
How many multi function spoilers are on each wing? What are their functions?
- 5
- 3 outboard spoilers are used to assist in roll control and for ground spoilers?
- 2 inboard spoilers are only used for ground spoilers
When will the speed breaks automatically close even if the lever shows deployed?
- Flap 2 or more
- Airspeed < 180kts
- TLA > 70 deg
What is the flap/slat extension/retraction sequences?
- Slats extend first
- Flaps retract first
Will loss of airspeed data cause the flight controls to go into ‘Direct’ mode?
Yes
Can a FCM override pilot input?
No, the pilot 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?
- Roll & Yaw Ailerons and Rudder surface repositioned to a new ‘neutral position’
- Pitch Horizontal Stabilizer
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
