The spoilers 2, 3, 4 and 5 use the same deflection; from configuration 0 to configuration 3, a threshold is included to minimize the drag. A 5 deg downward deflection of the ailerons (droop) is active when the flaps are extended. This position is identified by an index on the AIL scale of the ECAM F/CTL page (Ref 31-51).
-
The aileron droop function is ensured by each ELAC.
-
The aileron droop function is active on ground or in flight when the flaps are extended; in that case, a 5 deg downward deflection of the ailerons is ordered by the ELAC1 (or by the ELAC2 if it is active on the control of the ailerons).
- The aileron droop function is available as long as one ELAC is able
to control the ailerons.
- The ailerons are normally controlled by the ELAC1 through the left
Blue and the right Green servo-controls (active mode). The ELAC2 is
in stand-by, and the associated servo-controls are in damping mode.
In case of ELAC1 failure, the control of the ailerons is
automatically transferred to the ELAC2 which becomes active through
the left Green and right Blue servo-controls; in that case, the
servo-controls dedicated to the ELAC1 revert to the damping mode.
In case of double ELAC failure, or Blue and Green hydraulic low
pressure, all ailerons servo-controls are in the damping mode.

(4) Rudder control The pedals mechanically control the rudder position. The maximum rudder deflection is plus or minus 25. limited by the TLU. The trim authority is plus or minus 20. and its deflection rate is 1./s. The yaw orders from the roll normal law are sent to the yaw damper servo-actuators and added to the servocontrol mechanical input. Authority of these orders is given in the table below:
-------------------------------------------------------------------------------| | Less than or | | | | | V Cas (kts) | equal to 160 | 200 | 300 | 380 | |----------------|--------------|--------------|---------------|--------------| | | plus | plus | plus | plus | | | or | or | or | or | | | minus | minus | minus | minus | | Max. authority | 20.8. | 10.8. | 4.8. | 2.7. | -------------------------------------------------------------------------------The limitation of the rudder maximum deflection is given in the table
