Oral: Flight Controls Questions Flashcards
Know
What is the 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 –as airspeed increases, rudder deflection decreases
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 spoilers on each wing)
How manyspoilers are on each wing?
What are their functions?
- 5
- 3 outboard multi-function spoilers are used to assist in roll control, as speed brakes, and asground spoilers
- 2 inboard spoilers are only used asground spoilers
When will the speed brakes automatically close even if the lever shows deployed?
- Slat/Flaps selected to 2 or greater
- Airspeed < 180 kts.
- TLA > 70°
What is the flap/slat extension/retraction sequence?
- 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 always has supreme control
What happens to artificial feel if flight controls are disconnected?
Artificial feel is felt at ½ 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
