18
Q

On the Flight Control synoptic page, what does a yellow actuator status indicate

A

It indicates direct mode and at least one actuator is operational.

19
Q

When is the side slip target presented by a blue side slip skid indicator

A

When OEI during takeoff, climb or go around flight phase

20
Q

Where is the Low speed awareness (LSA) band located. The PLI’s?

A

Adjacent to the speed tape on the ADI

21
Q

List the three LSA bands in normal mode

A

1) Vss - top of the white tape - Low speed protection function
2) Vaoa - Top of the amber tape - AOA limiter function
3) Vlim - Top of the red tape - speed associated with the max allowable AOA airspeed.

22
Q

Do the Vss and Vaoa/Vlim indications behave the same in turns and other manuevers? Why or why not

A

No because Vss is defined in terms of speed and Vaoa/Vlim are defined in terms of AOA

23
Q

Do Vaoa and Vlim increase with load factor

A

Yes

24
Q

Is the AOA limiter function operational in Direct mode (DM)

A

No

25
Q

List the two LSA bands in Direct Mode and what they represent

A

1) Vms - top of the amber tape

2) Vsa - Top of the red tape, indicates the airspeed at which the stall aural alert is triggered.

26
Q

Are the pitch limit indicators (PLI’s) displayed in direct mode

A

No

27
Q

What color does the PLI become if the airspeed drops below Vaoa in Normal Mode (NM). What about Vlim

A
  • Amber and Red
28
Q

How many flight control computers (FCCs) are sufficient to provide Normal Mode (NM) functionality

A

One

29
Q

What is the purpose of the Black Airplane Battery

A

To withstand the operation for a minimum of 15 mins in order for the flight crew to recover the proper airplane electrical system operation.

30
Q

How long does each PBIT test of the FCS take

A

Less than 1 min

31
Q

If the PBIT conditions are not satisfied, up to how many PBIT operation attempts can the FCS automatically perform

A

Up to three

32
Q

During PBIT operation, which CAS message is displayed

A

The FLITCTRL TEST IN PROGRESS CAS

33
Q

When is the de-rotation control law active

A

When the aircraft touches down

34
Q

What does the neutral spiral stability control law provide

A

It automatically trims the elevator when the sidestick controller is set back to the neutral position to maintain flight level during turns up to 33 deg

35
Q

If the pilot commands a turn with a bank angle of greater than 33 deg, what do they need to do in order to maintain level flight in that turn

A

Maintain the desired sidestick lateral deflection an move the sidestick controller aft.

36
Q

List the 4 conditions that will cause the speed brakes to automatically stow

A

1) If the airspeed drops below 160kts
2) the TLA position is greater than 55 deg
3) The flap level position is set to 3 or full
4) The AOA limiter is engaged

37
Q

If the speed brakes are automatically stowed, what indication will the pilots have and how can the speed brakes be re-activated

A

The cyan SPDBRK LEVER DISAG CAS message is displayed and the SPEED BRAKE LEVER must be set back to stow.

38
Q

How is the manual reversion to Direct Mode (DM) available if the flight crew detects a Flight Control Normal Mode (NM) misbehavior

A

by a FLTCONTRL N-MODE FAIL CAS message

39
Q

What are the limits of the high speed protection envelope

A

The airspeed is limited to Vmo + 22 kts

40
Q

When does the pitch attitude protection activate

A

At pitch angles of 30 deg pitch up and 15 deg pitch down

41
Q

What does the limit flight envelope require?

A

More effort to maintain the airplane in this configuration.

42
Q

What are the boundaries/ hard limits of the flight envelope

A

The external boundaries of the limit flight envelope are reached at full control application. The hard limits of the limit flight envelope are the maximum AOA, airplane structural limits (load factor protection), maximum sideslip protection, and dive speed protection. There are no hard limits for pitch and bank angles.

43
Q

Is the AP operational in Direct Mode (DM)

A

No

44
Q

In direct mode, how does the airplane behave

A

Like a conventional airplane and the sidestick controller and pedal deflections are directly related to the surface position.
