0.75 with the autopilot engaged, the speedbrake retraction rate decreases (approximately 25 seconds are necessary to retract the speedbrakes from FULL to IN).
(2)
Speedbrake order The speedbrake order comes from the order received from the speedbrake lever received by the SEC. The speedbrake control order is inhibited:
-
if the monitoring of the speedbrake control transducer unit has detected a failure (by means of the transducer unit range monitoring or COM/MON comparison),
-
if the alpha protection is active,
-
if in FULL configuration,
-
in case of single elevator configuration,
-
in case of loss of the Blue and Green hydraulic pressures.
-
if at least one throttle lever is above MCT (Maximum Continous Thrust) or
-
if full back stick associated with pitch altitude protection,
The deflection rate is limited to 5./sec.
In order to do the test of the spoiler 1 on the ground, a 6.
extension of the spoiler 1 is possible with the speedbrake control
lever.

R (Ref. Fig. 011)
R (1) General
R The speedbrake function is ensured by the spoilers 2, 3 and 4 and the
R associated SECs.
R The speedbrake deflection order is dependent upon the speedbrake
R control lever position.
R Extension of the spoiler 2 is half the extension of the spoilers 3
R and 4.
R The speedbrake order is combined with roll orders.
R In flight, when the aircraft speed is more than 315 knots or Mach
R 0.75 with the autopilot engaged, the speedbrake retraction rate
R decreases (approximately 25 seconds are necessary to retract the
R speedbrakes from FULL to IN).

C. Speedbrake Function
(Ref. Fig. 011A)
(1)
General , The speedbrake function is ensured by the spoilers 2, 3 and 4 and the associated SECs. The speedbrake deflection order is dependent upon the speedbrake control lever position: Splr 4: 25 deg; Splr 3: 25 deg; Splr 2: 17.5 deg CONF 0/1/2, 12.5 deg CONF 3 for SPD BRK lever fully deflected. The speedbrake order is combined with roll orders. In flight, when the aircraft speed is more than 315 knots or Mach
0.75 with the autopilot engaged, the speedbrake retraction rate decreases (approximately 25 seconds are necessary to retract the speedbrakes from FULL to IN).
