‐ Thrust levers above MCT position.
‐ Alpha Floor activation.
If an inhibition occurs when the speedbrakes are extended, they automatically retract and remain
retracted until the inhibition condition disappears and the pilots reset the lever. (The speedbrakes can
be extended again, 10 s or more after the lever is reset).
When a speedbrake surface on one wing fails, the symmetric one on the other wing is inhibited.
Note: 1. For maintenance purposes, the speedbrake lever will extend the N° 1 surfaces when the
aircraft is stopped on ground, regardless of the slat/flap configuration.
2. When the aircraft is flying faster than 315 kt or M 0.75 with the autopilot engaged, the
speedbrake retraction rate is reduced (Retraction from FULL to in takes about 25 s).
L3 The maximum deflection for the spoilers is:
• 25 ° for spoilers 3 and 4;
• 12.5 ° for spoiler 2 in configuration 3, and 17.5 ° in other configurations.
For these surfaces (which perform both roll and speedbrake functions) the roll function has priority.
When the sum of a roll order and a simultaneous speedbrake order on one surface is greater than
the maximum deflection available in flight, the same surface on the other wing is retracted until the
difference between the two surfaces is equal to the roll order.

GROUND SPOILER CONTROL
Spoilers 1 to 5 act as ground spoilers.
When a ground spoiler surface on one wing fails, the symmetric ground spoiler surface on the
other wing is inhibited.
ARMING
The pilot arms the ground spoilers by pulling the speedbrake control lever up into the armed
position.

FULL EXTENSION – REJECTED TAKEOFF PHASE
�� If the ground spoilers are armed and the speed exceeds 72 kt the ground spoilers will
automatically extend as soon as both thrust levers are set to idle.
�� If the ground spoilers are not armed and the speed exceeds 72 kt the ground spoilers
will automatically extend as soon as reverse is selected on one engine (the other
thrust lever remains at idle).
FULL EXTENSION - LANDING PHASE
�� If the ground spoilers are armed and all thrust levers are at idle the ground spoilers
will automatically extend as soon as both main landing gears have touched down.
�� If the ground spoilers are not armed and both main landing gears have touched down
the ground spoilers will automatically extend as soon as reverse is selected on one
engine (the other thrust lever remains at idle).
Note: • In autoland, the ground spoilers fully extend at half speed one second after both
main landing gears touch down.
• The spoiler roll function is inhibited when spoilers are used for the ground spoiler
function.
PARTIAL EXTENSION
The ground spoilers partially extend (10 °) when reverse is selected on at least one engine
(other engine at idle), and one main landing gear strut is compressed. This partial extension,
by decreasing the lift, eases the compression of the second main landing gear strut, and
consequently leads to full ground spoiler extension.
RETRACTION
The ground spoilers retract :
• After landing, or after a rejected takeoff, when the ground spoilers are disarmed.
Note: If ground spoilers are not armed, they extend at the reverse selection and retract
when idle is selected.
• During a touch and go, when at least one thrust lever is advanced above 20 °.
Note: After an aircraft bounce, the ground spoilers remain extended with the thrust levers at
idle.
L3 The landing gear touchdown condition is triggered for both main landing gear, either when
their wheel speed is greater than 72 kt, or when their landing gear struts are, confirmed to be
compressed by the radio altitude (RA < 6 ft).
