The only fact I can see is that none of the traces for slat position and flap lever position is published.

It is interesting to note that the vertical speed trace never reaches the NCD status, but still the PF seems to indicate that he totally lost his V/S reading.
As long as the V/S was selected from IR the V/S trace was making sense, when the V/S was selected from ADR the V/S trace was becoming somehow erratic.
We may wonder why the V/S was occasionally selected from ADR (A33Zab said something on that, I have to find it back) does it have anything to do with the IRs capability ... what could be the consequences on the PFD's attitude display ?
