Alpha lock speeds
The alpha/speed lock function is activated when:
1. Alpha exceeds 8.6 or
2. Airspeed falls below 148 knots
Results of alpha/speed lock function: Retraction from position 1 to position 0 is
inhibited.
Inhibition removed when:
1. Alpha falls below 7.6 or
2. Speed exceeds 154 knots.
Alpha/speed lock function not active if:
1. Alpha exceeds 8.6 or airspeed falls below 148 knots after pilot has moved the flap
lever to 0; or
2. Aircraft is on ground with speed less than 60 knots.

When is PTU inhibited?
- When parking brake is set with only one engine master in on position .
- When nose wheel steering disconnect pin is installed and only one engine master is on.
- When PTU switch is off
- during cargo door operation ( continues approx 40 sec after door operation)
Alpha lock
This function inhibits slat retraction at high angles of attack and low speeds.
The SFCCs use corrected angle-of-attack (alpha) or airspeed information from the air
data inertial reference units (ADIRUs) to key the inhibition of slat retraction.
If alpha exceeds 8.5 (8° on A321) or the airspeed falls below 148 knots (165 knots
on A321), retraction from position 1 to position 0 is inhibited. The inhibition is
removed when alpha falls below 7.6 (7.1° on A321) or when the speed exceeds 154
knots (171 knots on A321).
This function is not active if:
– Alpha exceeds 8.5 (8° on A321) or the airspeed falls below 148 (165 knots on
A321) knots after the pilot has moved the lever to 0.
– The aircraft is on the ground with its speed less than 60 knots.
