Press and release the Normal Mode button.

Question 17

When is manual reversion to DM inhibited?

Answer 17

Low speed protection, high speed protection, or AOA protection.

Question 18

Answer 18

Green

Question 19

On the FLIGHT CONTROL synoptic page,what does a yellow actuator status indicate?

Answer 19

It indicates DM and at least one actuator is operational.

Question 20

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

Answer 20

OEI during takeoff, climb, or GA.

Question 21

Where is the Low Speed Awareness (LSA) band located? The Pitch Limit Indicators (PLI)?

Answer 21

LSA - Adjacent to the speed tape
PLI - ADI

Question 22

List the three LSA bands in NM and what they indicate.

Answer 22

Vss - top of the white tape - low speed protection
Vaoa - top of the amber tape - AOA limiter function
Vlim - top of the red tape - airspeed associated with max allowable AOA

Question 23

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

Answer 23

No, Vss is in terms of speed while Vao/Vlim are related to AOA.

Question 24

Does Vaoa and Vlim increase with load factor?

Answer 24

Yes

Question 25

Is the AOA limiter function operational in DM?

Answer 25

No.

Question 26

List the two bands in DM and what the represent?

Answer 26

Vms - top of amber tape Vsa - top of red tape - speed where aural stall warning is triggered.

Question 27

Are the Pitch Limit Indicators (PLI) displayed in DM?

Answer 27

No

Question 28

What color does the Pitch Limit Indicator become if the airspeed drops below Vaoa in NM? Vlim in NM?

Answer 28

Amber; Red

Question 29

How many FCCs are sufficient to provide NM functionality?

Answer 29

One.

Question 30

What is the purpose of the Black Airline Battery?

Answer 30

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

Question 31

How long does each PBIT of the FCS take?

Answer 31

Less than one minute.

Question 32

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

Answer 32

Up to three.

Question 33

During PBIT operation,which CAS message is displayed?

Answer 33

FLTCTRL TEST IN PROG.

Question 34

When is the de-rotation control law active?

Answer 34

When the airplane touches down.

Question 35

What does the neutral spiral stability control law provide?

Answer 35

It automatically trims the elevator when the sidestick controller is set back to the neutral position, to maintain the flight level during turns up to a bank angle of 33°.

Question 36

If the pilot commands a turn with a bank angle of greater than 33°, what needs to be done to maintain level flight in the turn?

Answer 36

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

Question 37

List the four conditions that will cause the speed brakes to automatically stow?

Answer 37

– FLAP Lever position is 3 or full ; – Airspeed is less than 160 kt; – TLA is greater than 55°; – The AOA limiter function is engaged.

Question 38

If the speed brakes are automatically stowed, what indication will the pilots have and how can they be reactivated?

Answer 38

SPDBRK LEVER DISAG; Speed brake lever must be stowed.

Question 39

Answer 39

NORMAL MODE button press and release.

Question 40

What do the CLAWs provide?

Answer 40

Protections to prevent the airplane from exceeding the flight envelope limitations.

Question 41

What are the two flight envelopes for the airplane?

Answer 41

Normal flight envelope and limit flight envelope.

Question 42

What are the limits of the normal flight envelope?

Answer 42

– 33° bank angle protection; – High speed protection (VMO); – Low energy avoidance protection (1.13 VS); – Pitch Attitude Protection.

What are the limits of the high speed protection envelope?

Answer 43

Vmo +22 kts.

When does pitch attitude protection activate?

Answer 44

30° pitch up 15° pitch down

Question 45

Answer 45

Requires more effort to maintain the airplane in this condition.

Question 46

What are the boundaries/hard limits of the limit flight envelope?

Answer 46

The external boundaries of the limit flight envelope are reached at full control application. The hard limits of this flight envelope are: – Maximum angle of attack - AOA limiter; – Airplane structural limits - load factor protection; – Maximum sideslip protection; – Dive speed protection.

Question 47

Is the AP operational in DM?

Answer 47

No.

Question 48

In DM, how does the airplane behave?

Answer 48

Like a conventional airplane, where sidestick and pedal deflection are directly related to surface position.
