From 2 h 10 min 05, the autopilot then auto-thrust disengaged
Apologies for butting in, but under what cicumstances or failure modes do these disengage, assuming not the action of the crew ?.
Trying to think logically: This is the first event in the chain. If we know the conditions under which the two disengage, perhaps we can work back from there ?...
