- Rudder limiting

5

FMA color codes?

Soonest auto pilot can be engaged?

- No sooner than 100feet AGL

8

Thrust lever detents?

- TOGA
- FLEX/MCT
- CL

9

Auto thrust is automatically armed when?

- During takeoff when the pilot moves thrust levers to the TOGA or FLEX detent

10

Thrust input found?

- EPR gauges

11

Thrust levers out of CL will?

- Limit the amount of thrust (message AUTO FLT A/THR limited)

12

Disconnecting AUTO THRUST

- Move to idle landing
- Match thrust lever position push one pb on lever

13

Blue is?

- Pilot selected

14

Magenta is?

- FMS managed

15

FMS flight phases for speed?

- Takeoff (TOGA or FLEX)
- Climb (Normally 1000 AGL)
- Cruise (Cruise alt)
- Descent (crew initiates)
- Approach (activated by crew)
- GO Around (TOGA)

16

SRS (Speed reference system) does?

- Available during takeoff / Go around
- Commands pitch alt
- V2 + 10 both engines
- V2 single engine
- Climb gradient of 1.2 limited to 18 degrees takeoff

17

S Speed is?

- Min airspeed for retracting the Flaps/Slats after Takeoff or Go around

18

F Speed is?

- Flap retraction speed

19

Vmax

- Computed by the FAC's
- Max speed for configuration
- Auto flight system will not let aircraft accel past

20

Passing through 10,000 aircraft will?

- Accelerate to ECON CLB

21

2 FAC's control?

- Rudder

22

2 ELAC's (elevator Aileron computer) control?

- Alerons

23

3 SEC's (spoiler elevator computer) controls?

- Spoiler / Elevator
- Backup for THS / Elevator control

24

Flight control laws?

- Normal Law
- Alternate Law
- Direct Law
- Mechanical backup

25

When do the ELAC's memorize the pitch altitude?

- 50 Feet AGL

26

When do ELAC's gently pitch down?

- 30 Feet AGL

27

Maneuvering protections, with flaps and without?

- With flaps extended +2.0 g max neg 0.0
- Without flaps extended =2.5 max neg 1.0

28

What is the pitch protection?

- Up 30 degrees
- Down 15 degrees

29

Roll protection?

- Full stick commands 15 degrees per second roll
- Out of center between 15 and 0 degrees

30

How much automatic picture trim for bank assistance?

- Up to 33 degrees

31

Bank angle is held up to?

- 33 degrees

32

Bank angle is limited to, if high speed protection is on or angle of attack is active?

- 45 degrees

33

Can Alternate Law be activated with a single failure of a flight control system?

- NO 2 or more failures must occure

34

When is Direct Law used?

- In landing because Alternate Law does not provide landing mode.

35

FAC Function?

- Y aw control (damping, turn coordination, rudder limiter, and rudder trim)
- A irspeed protection computation (alpha port. high/low limits, maneuver speed low speed limits PFD speed scale)
- W indshear protection
- L ow energy warning protection (speed, speed, speed)

36

What happens at Alpha prot?

- A OA is commanded instead of load factor
- S peed brake retracted
- A utopilot disengages
- P itch trim up is inhibited

37

Normal Law protections?

- B ank angle protection
- P itch angle protection
- L oad factor protection
- A ngle of attack protection (alpha prot)
- S peed protection

38

When do wing tip brakes engage to lock the slats and/or flaps? (4 red collared circuit breakers)

- R unaway
- O verspeed
- A symmetry
- M movement (un-commanded)

39

When is the low energy warning inhibited? (speed, speed, speed synthetic voice)

- Normal law not active
