STALL WARNING

Something is not clear with the STALL WARNING :

For the 330 the FCOM mentions there is no FLT PHASE INHIB.
In the meantime there is an EMERGENCY PROCEDURE called STALL WARNING AT LIFT-OFF when such warning may sound if an AoA probe is damaged. I would then think there is actually an inhibit as long as there is still WOW ...

For the 320 the FCOM (not updated) clearly mentions that the STALL WRN in inhibited on GND.

I see no logic behind the logic as described on page 20 in report #3 :
If the CAS measurements for the three ADR are lower than 60 kt, the angle of attack values of the three ADR are invalid (NCD status) and the stall warning is then inoperative. This results from a logic stating that the airflow must be sufficient to ensure a valid measurement by the angle of attack sensors, especially to prevent spurious warnings on the ground.
