Question 5

How is pitch trim force accomplished?

Answer 5

An electric motor driven actuator moves the horizontal stabilizer angle of incidence.

Question 6

When does the trim cutout on all axis?

Answer 6

After 3 seconds

Question 7

Which trim will sound an aural alert after 3 seconds of holding it?

Answer 7

Pitch Trim only

Question 8

How are pitch trim commands normally issued with the autopilot disengaged?

Answer 8

The spring-loaded control wheel pitch trim switch commands the Flight Control Electronics (FCE) 2, which in turn commands the Pitch Trim Actuator (PTA).

Question 9

How are pitch trim commands normally issued with the autopilot engaged?

Answer 9

The Automated Flight Control System commands the Flight Control Electronics (FCE)2, which in turn commands the Pitch Trim Actuator.

Question 10

How are pitch trim commands issued with PITCH BKP MODE switch in the BKP position?

Answer 10

The spring-loaded PITCH BKP DN/UP trim switch commands the Flight Control Electronics (FCE) 1, which in turn commands the Pitch Trim Actuator

Question 11

Is the autopilot available with the PITCH BKP MODE in the BKP position?

Answer 11

No

Question 12

How are roll trim commands issued?

Answer 12

The spring-loaded ROLL trim switch commands the Trim Actuator Controller

Question 13

How are yaw trim commands issued?

Answer 13

The spring-loaded YAW trim switch commands the Trim Actuator Controller

Question 14

Which axis of trim commands are issued through the Flight Control Electronics? (FCE)

Answer 14

Pitch only- Manual (AP off) and Automatic (AP on) through FCE 2, Backup through FCE 1

Question 15

IS pitch trim motion rate a function of airspeed in both Normal and Backup modes?

Answer 15

Yes, in both Normal and Backup, the higher the airspeed- the lower the trim rate, and vice versa.

Question 16

Are roll and yaw trim rate a function of airspeed?

Answer 16

No, roll and yaw trim operate at a fixed rate

Question 17

What are the 3 functions of the Multi-Function Spoilers?

Answer 17

-Roll Spoiler
-Ground Spoiler
-Speed Brake

Question 18

What criteria must be met for the Multi-Function Spoilers to deploy or remain deployed with the SPEED BRAKE switch in the OPEN position?

Answer 18

-Flaps Retracted
-Thrust Lever Angle < 38 deg (MAX CRZ)
-Airspeed > 125 knots

Question 19

What criteria must be met for the Ground Spoilers to arm with weight on wheels?

Answer 19

Wheel speed above 50kts

Question 20

What criteria must be met for the Ground Spoilers to arm with weight off wheels?

Answer 20

Weight off wheels > 10 seconds

Question 21

When armed, what criteria must be met for the Ground Spoilers to deploy?

Answer 21

-Both thrust levers less than 24 deg (halfway between IDLE and CRZ)

-Weight on wheels OR wheel speed Greater than 50 kts

Question 22

Below what wheel speed are the Ground Spoilers disarmed?

Answer 22

45kts

Question 23

Do the Ground Spoilers retract in the event of a bouncing touchdown?

Answer 23

No, the Ground Spoilers remain deployed for 10 seconds following weight off wheels, unless the thrust levers are advanced above 24 deg.

Question 24

Do the Ground Spoilers retract automatically the event of a touch-and-go maneuver?

Answer 24

yes, the panels retract if any thrust lever is advanced above 24 deg.

Question 25

What is the cockpit indication of Speed Brake or Ground Spoiler function?

Answer 25

SPDBRK or GND SPLR annunciation in SPOILER box (left portion of MFD)

Question 26

What criteria must be met for Spring loaded Rudder Booster (SLRB) activation?

Answer 26

FADEC detects thrust asymmetry

Question 27

Which component commands the Spring Loaded Rudder Booster (SLRB) activation?

Answer 27

FADEC

Question 28

Describe the function of the Spring Loaded Rudder Booster (SLRB)

Answer 28

When activated, a hydraulic actuator extends 2 springs, providing force to assist the pilot in moving the rudder to its limit.

Question 29
