Had you studied the events without any prejudice, you would have noticed that the auto-trim did its job as the maneuver demanded : Back stick and a decreasing airspeed.
At that moment, they went into a stall warning and probably because the system sensed both FACs failed, it went - correctly - into direct law, because of the extended gear.
It's because I studied the report that I can say that the auto trim didn't do its job when it was supposed to. After it trimmed the aircraft for low speed, the trim was blocked into that configuration even when not in direct law and while the stick was fully forward (have a closer look to the report).
Explaining that laws and systems worked correctly according to the wrong AoA info is not satisfying. The fact is that the aircraft was set in a wrong trim configuration without giving any proper feedback to the crew and that this configuration was kept while this auto trim should have worked on returning to a normal setting. Please tell me where is the benefit of having sidesticks without force feedback because this is the only reason while this auto trim is required in "manual" flying.
