The reasonable approach would be to have the autopilot engage in
straight and level automatically if the sensors detect an out of
control condition.

What would count as an out-of-control condition?

I stall, a spin, a spiral dive (excessive pitch down and speed) - many
things - as long as they are also with NO PILOT INPUT - then is it not a
good idea for such a system to "do something".?
