Poor grammar, Bonin indeed, not the A/C.

You miss one thing. The A330 is so adept and docile, it maintains the flight path through stall, without change in attitude, not consistent with its advertised fbw? So it morphs from flight path stable, to attitude stable in Stall, no? At least functionally, if not by design...

This is more the responsibility of the THS, to maintain good manners at +40 AoA?

"...by the way, even a non-Airbus aircraft autotrims as long as the autopilot is in control, and, as in Mali, that could be up until the stall and wing dip.."

Yes but AP was not flying. Manual flight for Bonin. Also in manual, the goal is to remain stable, to maneuver, not to cruise. Why Auto Trim for manual flight? The goal is maneuverability and stability, which demands equal authority in Pitch, not Nose Up or Down bias. Certainly not in low energy flight?

Airbus has added LEAP, an important safety improvement.... (Low Energy Alerting System)
Would an alert of low energy (STALL) separate from the STALLWARN have helped?
