Cool

Hi,

At 2 h 10 min 51
...13 degrees nose-up in about 1 minute and
remained in the latter position until the end of the flight.
IMHO the BEA are making a generalization saying THS stayed at +13 deg, or else how do we explain the pitch down inputs followed by a change in AoA. In which case this appears to be rather sloppy writing or a poor translation from the french original. What they should have said "...remained [mostly] in the latter position...".
The french note tell EXACTLY the same

Le plan horizontal réglable (PHR) passe de 3 à
13 degrés à cabrer en 1 minute environ ; il restera dans cette dernière position jusqu'à
la fin du vol.
It's a very affirmative statement from BEA and let no gap for interpretation.
So it stay on 13° to the end despite some elevators command to dive
Some justified this because the elevators commands to dive are too short .........
This must certainly be show better on the FDR than on the CVR
