Q

What is the purpose of the aileron and elevator disconnect handles?

A

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.

Q

While performing the stall barrier test, what does the auto-pilot disconnect button do if held in?

A

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.

Q

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?

A

Only one

25
Q

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?

A

Both

26
Q

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?

A

Only one normally

27
Q

Is there an automatic hard-over protection for the spoilers?

A

No

28
Q

What is the maximum speed with the Yaw Damper inoperative above 10000 ft?

A

260 kts

29
Q

What is the maximum speed with the Yaw Damper inoperative below 10000 ft?

A

250 kts

30
Q

The Vref speed that is shown in the display controller is based on what flight control configuration?

A

Flap handle position

31
Q

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?

A

Turn OFF the ground spoilers.

32
Q

If the aileron or elevator disconnect needs to be pulled but it won’t come up, what should you do?

A

Pull the Power Disconnect Assembly (PDA) trigger switch.

33
Q

What must be done in order to manually trim the elevator?

A

Turn the pitch trim switch off.

34
Q

What are the maximum speeds for flaps:
10°
20°
39° (full flaps)

A

250 KCAS
220 KCAS
170 KCAS

35
Q

What is the purpose of the standby rudder switch?

A

To provide rudder pressure with a dual hydraulic failure.

36
Q

Will the flaps operate in flight if the standby rudder is ON?

A

No, the standby rudder takes priority.

37
Q

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!

A

By pulling and resetting the appropriate circuit breakers on the cockpit overhead CB panel.

38
Q

Which flight controls does the autopilot have authority over?

A

Aileron and elevator

39
Q

What happens to the flight spoilers if the LATERAL CONTROL switch, located on the flight deck center left pedestal, is selected to OFF?

A

They are inoperative.

40
Q

With the system correctly armed, what will occur if the ground spoilers do not deploy on touchdown?

A

NO GROUND SPLRS lights located on the windshield center post will illuminate, master warning light,
GROUND SPOILERS CAS message.

41
Q

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?

A

Fly a minimum speed of 125 KCAS.

42
Q

When setting the pitch trim, what is the correct indication?

A

Verify on the FLIGHT CONTROLS 2/3 synoptic that trim is in the GREEN band and the digital trim value is also GREEN.

43
Q

With only batterie power, why is EMER STAB selected to ARM in order to set flaps 10°?

A

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

44
Q

What is the elevator deflection limit?

A

24° up and 13° down

45
Q

What is the elevator trim tab movement limit?

A

22° nose up

8° nose down

46
Q

What is the maximum rudder deflection under pilot control of the pedals?

A

22°

Only at slow speeds

47
Q

What is the rudder trim deflection on either side?

A

7.5°

48
Q

What is the correct indication to observe when setting the pitch trim?

A

Verify on the FLIGHT CONTROLS 2/4 synoptic that trim is in the green band and the digital trim value is also green

49
Q

How might an aileron hardcover condition be determined to be correctable or corrected?

A

By what the condition was prior to HOPS activation, such as moderate or severe turbulence

50
Q

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

A

Fly a min speed of 125KCAS

51
Q

What switches must be selected ON to perform a stall barrier test?

A

Stall barrier switch on the center pedestal, and AOA probe heat on the overhead panel

52
Q

How many static wicks can be missing from the wings

A

2 only one per wing

53
Q

How many static wicks can be missing from the tail

A

Two

54
Q

What is the max deflection of the ground spoiler panels

A

55° +/- 4°

55
Q

How are the ground spoiler normally activated on the ground?

A

Wheel spin up >47 knots, or weight on wheels

56
Q

Where is the aileron trim tab located

A

On the left aileron

57
Q

What is the purpose of the GPWS/GRD SPLR FLAP ORIDE switch

A

When landing with less than full flaps, the switch allows ground spoilers to deploy (when armed) during wheel spin up in addition to WOW

58
Q

What will happen if the power levers are advanced for takeoff with the GPWS/GROUND SPLR FLAP ORIDE switch ON

A

A red AIRCRAFT CONFIGURATION CAS message will illuminate
