Hi Clandestino,

You are acquainted with sidestick traces from 3rd intermediate report, aren't you?
Yes thanks.

See Page 74.
"The PF copilot said “I have the controls” and made rapid and high amplitude lateral, almost stop to stop, inputs. He also made a nose-up input that increased the airplane’s pitch attitude
up to 11° in ten seconds……."

The nose up request on the side stick rotated the aircraft by about 1 deg per second. If they had been in Direct Law, as the speed washed off, the nose would have wanted to drop and the back stick pressure would have been less effective. The aircraft may have stabilised at a speed above the stall whilst still holding the same back stick pressure.

Do you think it is easier to stall in Direct or Alternate LAW?
