The amplitude of the SS inputs are also pretty disturbing...

Here's the beginning;
2 h 10 min 05 Altitude=35024
The P/A2 disengages.
The roll angle from 0 to 8.4 ° in 2 seconds while the handle is in neutral.
The pitch is 0 degrees.
Cavalry charge (Alarm: disconnection autopilot)
2 h 10 min 06
The flight control law passes from normal to alternate. PF: "I have control"
During the period 2 h 10 min 07-2 h 10 min 18
The SS is positioned:
- To pitch between neutral and ¾ stop
- Left half and then stop right half-stop, 2 times, alternating left until it stops then right to the half-stop (period 4 seconds).
The pitch increases to 11 °.
The vertical acceleration varies between 0.9 g and 1.6 g.
The roll angle is between 11 ° right and 6 left.
The vertical velocity increases up to 5200 ft / min.
So the first SS input at 0.8M/FL350 is 3/4 of the SS travel NU, with an equally significant full-left and then 1/2-right alternating inputs over a period of 4 seconds... pitch started at 0 degrees at 2h10m05 and is 11 degrees at 2h10m18

<snip>

2 h 11 min 32:
OPL is the handle:
- Set to pitch, reached the
stop after 6 seconds and there
remains up to 2 h 12 min 15
etc...

Apologies for the Google Translate.
