From the outset and per BEA the PF made one NURL at a/p drop. It was not continuous. The climb is unexplained, although High speed Prot is a candidate, certainly.
FWIW, that quote isn't from me, it's from bearfoil.
The report does not explicitly say how long the nose-up input was.
Indeed, which leaves one wanting in terms of understading PF actions.
IMHO it was continuous from 2h 10 min 05 "...nose up input." until 2 h 10 min 16 "...nose-down control inputs". At most this was for 11 seconds and resulted in the climb from FL350 to FL375 which sounds reasonable.
Ten seconds of nose up input. Continuous or intermittent?
If continuous, that's quite a bit of nose up).
(What can you do with ten seconds of sustained "nose up" command in a given aircraft. ) Well, in a small plane, I could loop a T-28 in around ten seconds of continuous nose up (pitch toward stomach) input (a 3.5 g maneuver) back when the earth was nearly new ,and I was learning to fly.
I doubt AF 447 pitch input was anywhere near 3.5 g, heck, the acft control system is limited to 2.5 g pull.
Unfortunately the IAS on the right PFD used by PF was not recorded on the FDR. Did the ADIRUs give bogus attitude indications? It would explain the bizarre "inputs made by the PF were mainly nose-up".
Aye. thanks.
