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

a. Partial – When reverse thrust is selected on at least one engine with the other at idle and one main landing gear strut is
compressed

b. 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

a. SEC 1 and 3 have failed
b. AOA protection is active
c. Flaps FULL
d. Elevator (L or R) fault (only spoilers 3 and 4 are inhibited)
e. 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
