@ studi, Svarin, blind pew and those who think "that the climb was not induced by the pilots but by some sort of ill functioning protection":
May I kindly ask:
- what protection you refer to / could you elaborate on why/how it's been triggered (with AP&ATHR OFF since 2 h 10 min 05, and ALT2 law active since 2 h 10 min 16 at the latest)?
- why/how do you seem do discart the followings?
From 2 h 10 min 05, the autopilot then auto-thrust disengaged and the PF said "I have the controls". The airplane began to roll to the right and the PF made a left nose-up input.
