Flight Control 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 speed
- 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 multifunction spoilers (outer 3 spoilers on each wing)
How many spoiler are on each wing? What are their functions?
- 5
- 3 outboard multifunction 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 its
- 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 fell 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 multifunction spoilers function in DIRECT mode?
Yes, for roll only and a default fixed gain
Will the speed brake/ground spoilers function in DIRECT mode?
- No
