Flight Controls Flashcards
Use of speed brakes with the HMG in operation
Slow operation (Approximately 3 sec for full range of movement)
Speed brakes not approved for extension in flight when
Flaps are at 39° or landing gear extended
Takeoff permitted with automatic ground spoilers inoperative provided:
Anti-skid is operative
Flaps 20° are used
Cowl and wing systems are not used
What is indicated by the red NO GROUND SPOILERS lights on the windshield center post?
All conditions have been met, but the ground spoilers did not deploy
What is the function of the emergency stab switch?
It de-couples the STAB-FLAP sync signal and allows the stab to be moved by using the pitch trim switches
Selecting the spoiler control switch to OFF will disable what controls?
Ground spoilers, flight spoilers, and speed brakes
How can an inadvertent HOPS activation be reset?
By pulling and resetting the appropriate circuit breakers on the cockpit overhead circuit breaker panel
What will occur if landing at a flap setting of 20° or less and the EGPWS/FLAP OVERIDE SWITCH is not selected to ON?
The EGPWS will announce TOO LOW FLAPS, and the ground spoilers will not deploy on wheel spin up
If a touch and go is to be performed, the ground spoilers switch should be selected to what?
OFF
What action should be taken immediately in the event of NO GROUND SPOILERS lights illuminate after touchdown?
Manually extend the speed brakes
If the automatic hardcover protection system senses a difference between elevator input and output and activates, what effect will it have on the elevator?
Operative but without the benefit of the affected sides hydraulic boost
What will happen if the autopilot is selected on with the pitch trim in the OFF position?
The pitch trim will automatically engage
Which hydraulic system can operate the flaps?
Left, PTU, AND AUX
In flight, what do the flight spoilers do?
Act with the ailerons to improve roll response
How is the horizontal stabilizer powered?
Aircraft electric system, AC power
What precaution should be observed prior to engaging the gust lock?
Make sure the left and right pressure is zero psi
How are the flaps set at 10° for the preflight inspection?
- emergency stab to ARM
- Aux pump on
- Flaps 10°
What is indicated by an amber “SPEED BRAKE EXTENDED” CAS message?
The speed brakes are extended with the power levers above IDLE.
Can the stall barrier switch be selected OFF in flight?
Yes, however an operative stall barrier system must be ON during all flight operations unless it is malfunctioning.
What is the purpose of the aileron and elevator disconnect handles?
In the unlikely event that an aileron or elevator becomes jammed, either one of the handles can be pulled to fully separate the ailerons (AIL DISC) or elevator (ELEV DISC) to operate the control wheels independently.
While performing the stall barrier test, what does the auto-pilot disconnect button do if held in?
Releases the electric pitch trim and stops run-away electric trim,
Stops the flaps/stab from moving,
Deactivates the stick pusher, the stick shaker is still active.
Note: Stick pusher is still active on JAA certified airplanes.
While performing the stall barrier test, at what AoA do you expect the stick shaker and stall barrier to activate?
Stick shaker will activate at AoA 0.85 followed 1/2 second later by the stick pusher which activates at AoA 1.0
How do you know if the PITCH TRIM and YAW DAMP are engaged?
The switch capsule lights are extinguished
If a hard-over is sensed in one elevator actuator, will only the affected elevator be shut off or will both actuators be shut off?
Only one
If a hard-over is sensed in one aileron actuator, will only the affected aileron be shut off or will both actuators be shut off?
Both
If a hard-over is sensed in one rudder actuator, will only the affected rudder be shut off or will both actuators be shut off?
Only one normally
Is there an automatic hard-over protection for the spoilers?
No
What is the maximum speed with the Yaw Damper inoperative above 10000 ft?
260 kts
What is the maximum speed with the Yaw Damper inoperative below 10000 ft?
250 kts
The Vref speed that is shown in the display controller is based on what flight control configuration?
Flap handle position
In the event the landing gear handle will not come up after takeoff, followed by an amber WOW FAULT and red GROUND SPOILER CAS message, what action should be taken immediately?
Turn OFF the ground spoilers.
If the aileron or elevator disconnect needs to be pulled but it won’t come up, what should you do?
Pull the Power Disconnect Assembly (PDA) trigger switch.
What must be done in order to manually trim the elevator?
Turn the pitch trim switch off.
What are the maximum speeds for flaps:
10°
20°
39° (full flaps)
250 KCAS
220 KCAS
170 KCAS
What is the purpose of the standby rudder switch?
To provide rudder pressure with a dual hydraulic failure.
Will the flaps operate in flight if the standby rudder is ON?
No, the standby rudder takes priority.
The Hard Over Prevention System (HOPS) compares pilot input with actuator output.
If a hard over is detected, hydraulic power to the actuator will be shut off.
How is the system reset!
By pulling and resetting the appropriate circuit breakers on the cockpit overhead CB panel.
Which flight controls does the autopilot have authority over?
Aileron and elevator
What happens to the flight spoilers if the LATERAL CONTROL switch, located on the flight deck center left pedestal, is selected to OFF?
They are inoperative.
With the system correctly armed, what will occur if the ground spoilers do not deploy on touchdown?
NO GROUND SPLRS lights located on the windshield center post will illuminate, master warning light,
GROUND SPOILERS CAS message.
When landing with less than full flaps and the FLT REF page of the display controller indicates a Vref of less than 125 KCAS, what is the procedure?
Fly a minimum speed of 125 KCAS.
When setting the pitch trim, what is the correct indication?
Verify on the FLIGHT CONTROLS 2/3 synoptic that trim is in the GREEN band and the digital trim value is also GREEN.
With only batterie power, why is EMER STAB selected to ARM in order to set flaps 10°?
By selecting EMER STAB to ARM, the STAB is electrically disconnected from the FLAP/STAB computer, allowing the flaps to move by AUX HYD and DC power alone
What is the elevator deflection limit?
24° up and 13° down
What is the elevator trim tab movement limit?
22° nose up
8° nose down
What is the maximum rudder deflection under pilot control of the pedals?
22°
Only at slow speeds
What is the rudder trim deflection on either side?
7.5°
What is the correct indication to observe when setting the pitch trim?
Verify on the FLIGHT CONTROLS 2/4 synoptic that trim is in the green band and the digital trim value is also green
How might an aileron hardcover condition be determined to be correctable or corrected?
By what the condition was prior to HOPS activation, such as moderate or severe turbulence
What is the procedure when landing less than full flaps and the FLT REF page of the display controller indicates Vref of less than 125knots
Fly a min speed of 125KCAS
What switches must be selected ON to perform a stall barrier test?
Stall barrier switch on the center pedestal, and AOA probe heat on the overhead panel
How many static wicks can be missing from the wings
2 only one per wing
How many static wicks can be missing from the tail
Two
What is the max deflection of the ground spoiler panels
55° +/- 4°
How are the ground spoiler normally activated on the ground?
Wheel spin up >47 knots, or weight on wheels
Where is the aileron trim tab located
On the left aileron
What is the purpose of the GPWS/GRD SPLR FLAP ORIDE switch
When landing with less than full flaps, the switch allows ground spoilers to deploy (when armed) during wheel spin up in addition to WOW
What will happen if the power levers are advanced for takeoff with the GPWS/GROUND SPLR FLAP ORIDE switch ON
A red AIRCRAFT CONFIGURATION CAS message will illuminate
