Flight Controls Questions Flashcards
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 many spoilers 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 as ground spoilers
- 2 inboard spoilers are only used as ground 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
