I always thought that on the B737 Boeing kept the big clunky control column , clattering trim wheel and oversized moving throttles for a reason.
That is that you don’t need a warning system. Its in your face.
In most of the UAs , SA problems described above crews have watched on while things get clearly out of shape.
How you train to mitigate against that in already full training schedules I don’t know.
But I do know that when I have seen these scenarios repeated in the sim. the instructors input is usually
“ Don’t disconnect now , let it fully develop”
How do you manufacture airmanship ?
