At 2 h 12 min 02, the PF said "I don’t have any more indications", and the PNF said "we have no valid indications". At that moment, the thrust levers were in the IDLE detent and the engines’ N1’s were at 55%. Around fifteen seconds later, the PF made pitch-down inputs. In the following moments, the angle of attack decreased, the speeds became valid again and the stall warning sounded again.
If you don't trust the PDF and all the magic, isn't this what the ISIS is for? Also, what were the engines doing at IDLE only 70 seconds or so after they commanded TOGA power? They must have really been confused.
