Default Stability augmentation promises to give you even less control

OK, then single pilot in real IMC.


That's what wing levelers are for.


Not while manuevering, which is when the system would be active.


Another would be inadvertent VFR flight into IMC.


Though I will admit that since there has to be an autopilot installed which
this thing is installed on top of, it does sound a little like having a
belt and suspenders.

The reasonable approach would be to have the autopilot engage in
straight and level automatically if the sensors detect an out of
control condition. Not sure if a conventional A/P knows how to recover
from a spin, but that would be a modest software patch.


The article mentions loss of control as a major factor in the accident rate
without going into any details of what that means.

I can see the utility of something that monitors angle of attack and nudges
the nose down when it determines a stall is emminent.

Jim,with respect, if some device decided I wanted back pressure
released when a stall is pending that device and I would have a
discussion -- my end of it would be with wire clippers or a hammer! --
because when I'm landing the AoA is in the stall range and I don't
want the nose wheel to touch down first, especially on a soft field.
It would take somewhat better programming than simply AoA. On the
other hand, my airplane never sees pitch and bank close to the
statutory limits, Those might be worth considering. Wait a minute,
maybe not. I would not want something to intervene if I needed big
pitch or bank inputs if trying to avoid another airplane or the like.
I'm guessing optimal spin recovery would be ok though, optimal being
defined as minimal loss of altitude. And maybe something to avoid the
JFK Jr kind of pilot auguring into the ocean.
