Answer 11

Flight Augmentation Computer

Question 12

How many FACs are installed?

(FCOM-DSC-27-10-10)

Answer 12

2

Question 13

What are the functions of the FACs?

(FCOM-DSC-27-10-20)

Answer 13

a. Normal roll (turn coordination and yaw damping)

b. Rudder trim

c. Rudder travel limit

d. Alternate yaw

Question 14

Under Normal Law, what do the FACs provide?

(FCOM-DSC-22-40-10)

Answer 14

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”)

Question 15

Is full rudder deflection available during all flight regimes?

(FCOM-DSC-27-10-20)

Answer 15

No. Rudder deflection is limited as a function of airspeed

Question 16

How are the flight control surfaces controlled and actuated?

(FCOM-DSC-27-10-10)

Answer 16

All surfaces are controlled electrically and actuated hydraulically

Answer 17

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

Question 18

How is roll control normally achieved?

(FCOM-DSC-27-10-20)

Answer 18

1 aileron and 4 spoilers on each wing

Question 19

If both FACs fail, is maximum rudder deflection available?

(FCOM-DSC-27-10-20)

Answer 19

Yes, after slat extension
