BOAC, "The system has trimmed my tail to the point where I may not be able to fly out of it."
The system includes the pilot. And it was direct pilot input that caused that trim setting to exist. I also note it MAY be time for a remedial read on the BEA release again. The trim stayed sane until after the PF input full NU (and full left.)

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.
