At 2 h 10 min 51 the stall warning was triggered again. The thrust levers were positioned in the TO/GA detent and the PF maintained nose-up inputs. The recorded angle of attack, of around 6 degrees at the triggering of the stall warning, continued to increase. The trimmable horizontal stabilizer (THS) passed from 3 to 13 degrees nose-up in about 1 minute and remained in the latter position until the end of the flight."
Is it normal for the stall warning to be triggered at 6 degrees ? To the uneducated this appears quite low. Wouldn't the stall AOA in clean config be around 13-15 degrees?
If the aircraft was still in Alternate Law as indicated by PNF is there anyway the automatics could trigger an uncommanded (by the pilots) THS nose-up change of 10 degrees?
Can anything be read into the rate of increase in nose up ? To the uneducated it appears relatively slow / deliberate ?
