S.F.L.Y. you asked
Who told you no auto trim ? The plane was in Alt law and most of these 20s were with forward stick. Why then the ths didn't show any sign of movement toward the -5 setting matching with the 2500ft 120 Kias level-off ?
Nobody told me, I worked it out using the FDR readout and FCOM 1. If > 50° NU pitch, or > 30°ND pitch, or below 60kt, Abnormal Attitude law applies, which is Alternate Law in pitch with no autotrim. If you examine the readouts you will see that abnormal Attitude law would have applied for all but 5 or 6 seconds of the last 26.
The 2500ft 120 Kias level-off (your words) occurred at about 15:45:23 with the a/c in Direct law - so any movement of the THS would be done manually by the pilot. I do not know why the THS did not move - perhaps the CVR will tell us.
The HYD system page was displayed on ECAM at 15:45:48 - during the ultra-low-speed period - which
may indicate that the crew were checking for HYD problems affecting the THS. Again perhaps the CVR etc...
CONF asked
Where are the graphs for the FO side stick position ?
I think if you compare the Captain's sidestick position in roll(direct) and the aileron deflection the two match perfectly; in pitch Direct phase the sidestick and elevator position match; when back in alternate law in pitch at about 15:45:50 there is a period of full up elevator which does not match... but that will happen in that control law by design.
