UAS can be a difficult problem to recognize as it can be caused by multiple scenarios which lead to it.
Perhaps .. but this highlights one of the greybeards' concerns in these days of super-automation.
In days past, regardless of widgets, bells and whistles, the flying pilot was always aware of the underlying pitch and thrust settings in relation to what the aeroplane was required to be doing at the time .. ie looking throught the FD to the ball.
If the picture didn't quite gel, there was something awry .. just what that might have been may not have been quite obvious at the time .. but the immediate problem of control was addressed by a constant monitoring of pitch and thrust aligned with comparison between attitude systems to identify what was telling the truth.
If need be the pilot would discount the bells and whistles and go back to DC3 techniques. Not elegant, perhaps, but generally functional.
Progress can have its downside ..
