Flight Controls Flashcards
Normal and direct mode
There are no higher lever functions available in direct mode
What are the higher level functions associated with pitch?
Gain airspeed
Elevator thrust compensation
AOA limiting
What is connected to gear box?
F. FUEL PUMP
I. IDG
S. STARTER (air turbine starter)
H. Hydraulic Pump
O. Oil pump
I
L
PMAWhat are the higher level functions associated with yaw?
Yaw damp
Turn coordination
Thrust asymmetry
Gain on airspeed - as airspeed increases, rudder deflection decreases
Not fly by wire
Ailerons
What is the priority for 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 multifunction 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
Oral
When will the speed brakes automatically close even if the lever shows deployed?
Flaps >2
Airspeed 70 degrees
What is the flap/slat extension/retraction sequence?
Slats extend first
Flaps extend first
What is the priority for the trim system?
Backup
Captain
First Officer
Autopilot
How is roll controlled?
Ailerons and multifunction spoilers (outer 3 spoilers on each wing )
Will loss of airspeed data cause the flight controls to go into direct mode?
Yes
Can a FCM override a pilot input?
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
How are the flight controlls trimmed?
Roll and 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 defaulted fixed gain
Will the speed brakes/ ground spoilers function in ‘ direct’ mode?
No
What happens to the to the flight control system when the RAT is the only AC power source?
Horizontal stab trim operates at 1/2 speed?
Slat / flap system operates 1/2 speed?
Slat / flap position is limited to ‘3’ to allow adequate airspeed for the RAT
What is the only primary flight control that is not FBW (Fly By Wire)?
Ailerons
