HN39:
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.
The PF maintained nose-up inputs. So the question is whether a nose-up input not to the wall will activate autotrim or not. I suspect it will simply because the ride for the SLF would be kind of rough if autotrim only responded to a full forward or backwards stick motion.
In that case maintaining the nose-up stick input will bring THS upwards to its limits over time.
