*Flight Control-Speed Brake/Spoilers

Question 1

Is there any landing configuration when speed brake extension is inhibited?

Answer 1

Flaps Full

Question 2

In flight, what happens if a spoiler fault is detected or electrical power is lost?

Answer 2

The spoiler automatically retracts.

Question 3

When do the Ground Spoilers automatically extend?

Answer 3

Partial- When reverse thrust is selected on at least one engine with the other at idle and one main landing gear strut compressed.
Full- At touchdown of both main gears, or in case of RTO with airspeed above 72 knots, when BOTH thrust levers at IDLE (if ground spoilers armed) or when reverse thrust is selected on at least one engine with the other thrust lever at IDLE (if ground spoilers are not armed).

Question 4

At touchdown, with the reverse selected and only one landing gear strut compressed, will the ground spoilers extend?

Answer 4

Partially- Full extension is limited until both main gear struts are compressed.

Question 5

When will the ground spoilers automatically retract?

Answer 5

When at least one thrust levers is advanced above IDLE.

Question 6

When is speedbrake extension inhibited? (SAFET)

Answer 6

SEC 1 and 3 have failed.
AOA protection is active.
Flaps FULL.
Elevator (L or R) fault (only 3 and 4 inhibited).
Thrust levers above MCT.

Question 7

What is the difference between A319 and A320 regarding speed brake usage with the AP on?

Answer 7

With the A319 you get full spoiler deflection, with the A320 you get only partial deflection.
