Speedbrake/Spoilers

Question 1

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

Answer 1

Flaps FULL

Question 2

When do the Ground Spoilers automatically extend?

Answer 2

Partial – When reverse thrust is selected on at least one engine with the other at idle and one main landing gear strut is compressed
Full – At touchdown of both main gear , 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 the ground spoilers are not armed)

Question 3

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

Answer 3

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

Question 4

When will the ground spoilers automatically retract?

Answer 4

When at least one thrust lever is advanced above IDLE

Question 5

When is speedbrake extension inhibited (SAFET)?

Answer 5

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

Question 6

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

Answer 6

The spoiler automatically retracts

Question 7

What is the difference between the A319 - A321 and A320 regarding speed brake usage with the AP on?

Answer 7

With the A319 and 321 you get full spoiler deflection and with the A320 you only get partial spoiler deflection
