The SFCC memory keeps the last correct signal, which controls the slat and flap position. The SFCCs compare a new CSU signal with the slat position signal which comes from the FPPU. If a change of slat angle is necessary, the PCU solenoids get electrical power. The slats move towards the new position (Ref. 27-54-00). When the position data from the FPPU is the same as the CSU signal, the slats stop.
NOTE : Slat and flap movement always obeys the last correct control
____ lever movement. For example, when the lever moves from position 3 to FULL, the slats will extend in the direction of the FULL position. If the lever returns to position 3 before the slats reach position FULL, the direction of slat movement changes and the slats move back to position 3.

B. Slat Alpha Lock/Speed Baulk
The Air Data/Inertial Reference Units (ADIRU) supply corrected angle-of-attack (alpha) and computed air speed (CAS) data to the SFCC. The SFCC use the data to prevent slat retraction at high alpha and/or low CAS. Slat retraction is not possible if:
-
the alpha is more than 8.5 deg.
-
the CAS is less than 148 knots.
The function resets if alpha decreases below 7.6 deg. or CAS increases over 154 knots.
Alpha lock/speed baulk is not possible if:
-
the slat retraction is set before alpha is more than 8.5 deg. or CAS less than 148 knots
-
the aircraft is on the ground with CAS below 60 knots.
When the function is active, the ECAM shows the message A-Lock (cyan, pulsing) below the slat position indication (Ref. 27-85-00).

B. Slat Alpha Lock/Speed Baulk
The Air Data/Inertial Reference Units (ADIRU) supply corrected angle-of-attack (alpha) and computed air speed (CAS) data to the SFCC. The SFCC use the data to prevent slat retraction at high alpha and/or low CAS. Slat retraction is not possible if:
-
the alpha is more than 8.0 deg.
-
the CAS is less than 165 knots.
The function resets if alpha decreases below 7.1 deg. or CAS increases over 171 knots.
Alpha lock/speed baulk is not possible if:
