Flight Controls Flashcards
What is the difference between normal mode and direct mode?
There are no higher level functions available in direct mode.
What is the only primary flight control that is not FBW (Fly-By-Wire)?
Ailerons
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- 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 multifunction spoilers are on each wing? What are their functions?
3 outboards spoilers are used to assist in roll control and for ground spoilers and speed brakes.
2 inboard spoilers are only used for ground spoilers (not considered MFS)
When will the speed brakes automatically close even if the lever shows deployed?
Flaps 2 or greater
Airspeed <180kts
TLA 70°
What is the flaps/slats 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 inputs?
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.
CA side keeps artificial feel.
FO side looses it.
How are the flight controls trimmed?
Roll and Yaw Ailerons and Rudder surface reposition to a new ‘neutral position’.
Pitch Horizontal Stabilizer
Will the multifunction spoilers function in ‘DIRECT’ mode?
Yes, for role only and at the default fixed again
With the speed breaks/ground spoilers function in ‘DIRECT’ mode?
No
