4
Q

Under Normal Law, what does ELAC 1 control?

(QRH OPS.03A)

A

Primary - Aileron control (roll)

Standby - Elevator / Trimmable Horizontal Stabilizer control (backs up ELAC 2)

5
Q

Under Normal Law, what does ELAC 2 control?

(QRH OPS.03A)

A

Primary - Elevator / Stabilizer (pitch)

Standby - Aileron control (backs up ELAC 1)

6
Q

A

3

8
Q

What functions are performed by the SECs?

(FCOM-DSC-27-10-20)

A

a. Normal roll (by controlling the spoilers)

b. Speed brakes and ground spoilers (SEC 1 & 3 only)

c. Alternate pitch (SEC 1 & 2 only)

d. Direct pitch (SEC 1 & 2)

e. Direct roll

f. Abnormal attitude

9
Q

Under Normal Law, what do the 3 SECs control?

(QRH OPS.03A)

A

Primary – Spoiler control (roll)

Standby – Elevator / Stabilizer control (SEC 1 & 2 back up the ELACs)

10
Q

What is the sole purpose of SEC 3 in Normal Law?

(FCOM-DSC-27-10-20)

A

Spoiler control

(Spoilers 1 & 2 only)

11
Q

What is the definition of FAC?

(FCOM-DSC-27-10-10)

A

Flight Augmentation Computer

12
Q

How many FACs are installed?

(FCOM-DSC-27-10-10)

A

2

13
Q

What are the functions of the FACs?

(FCOM-DSC-27-10-20)

A

a. Normal roll (turn coordination and yaw damping)

b. Rudder trim

c. Rudder travel limit

d. Alternate yaw

14
Q

Under Normal Law, what do the FACs provide?

(FCOM-DSC-22-40-10)

A

Y - Yaw Control – Damping and turn coordination, rudder limiter, rudder trim)

A - Airspeed Protection Computation (Alpha Prot, high / low limits, maneuvering speed, PFD speed scale)

W - Windshear protection (Reactive and not Predictive)

L - Low Energy Warning Protection (“SPEED, SPEED, SPEED”)

15
Q

Is full rudder deflection available during all flight regimes?

(FCOM-DSC-27-10-20)

A

No. Rudder deflection is limited as a function of airspeed

16
Q

How are the flight control surfaces controlled and actuated?

(FCOM-DSC-27-10-10)

A

All surfaces are controlled electrically and actuated hydraulically

17
Q

When is automatic pitch trim available?

(FCOM-DSC-27-20-10-20)

A

In flight under Normal law with bank angle less than 33° with or without autopilot engaged.

18
Q

How is roll control normally achieved?

(FCOM-DSC-27-10-20)

A

1 aileron and 4 spoilers on each wing

19
Q

If both FACs fail, is maximum rudder deflection available?

(FCOM-DSC-27-10-20)

A

Yes, after slat extension
