RE BOAC (#4121)
Not being AB myself, I just try to understand the FCOM (Smart Cochpit and another source). I understand that "low speed protection" is a flight control function (ATA 27) while "audio stall warning" is generated by the Flight Warning Computer (see "smart cockpit", ATA 31, Indicating and Recording Systems 1-31-10 Page 4). I may be wrong but I think these two functions are completely independent.
