Flight control

Question 1

The elevators, ailerons and rudder are … actuated

Answer 1

Mechanically

Question 2

The spoilers and flaps are … actuated.

Answer 2

Hydraulically

Question 3

In case of jamming, pitch control will be recovered by disengaging the pitch coupling system (by applying a differential force of … ).

Answer 3

52 daN

Question 4

GUST LOCK lever

Answer 4

Permits to lock mechanically the roll and pitch axes against the wing gusts.

The PL travel is limited to slightly above FI.

Question 5

AIL LOCK

Answer 5

For aircraft equipped with a spring tab on the aileron, the roll locking system is composed of two electro-mechanical
locking devices.

The AIL LOCK is triggered whenever one of the locking actuators is in disagreement with the gust lock position (lock or unlock position)

Question 6

STICK SHAKER/PUSHER PB

• FAULT
• OFF

Answer 6

– FAULT light indicates a stick
pusher or stick shaker failure

– OFF position: enables to switch
OFF the stick pusher and the stick
shaker system

Question 7

PITCH PUSHER
illuminates to indicate that the
stick pusher is

Answer 7

Operating

Question 8

SPOILERS position indicator illuminated blue (triangle)

Answer 8

The associated spoiler is not in the fully retracted position (more than 2.5° aileron travel)

Question 9

PITCH TRIM ASYM

Answer 9

light illuminates to indicate a pitch tabs

desynchronization greater than 0.7°

Question 10

EXT flag

Answer 10

Appears to indicate that the flaps valve is hydraulically commanding flap extension.

If EXT flag appears when flaps are extended, it means that there is a leak in the flaps hydraulic circuit
