A good example of this is one of my first RAAF students was a commercial pilot with about 2000 hrs experience.Upset recovery training is now mandated by CASA as an event in recurrent cyclic simulator sessions. The last ones i did included nose high, nose low with varying airspeeds and varying angle of bank. Extreme attitudes are included (140 degrees angle of bank which is almost inverted) etc.
No automation is used to recover from unusual attitudes - in fact a lot of the time if you found yourself in one then it would most likely be inattention to what the autopilot was doing (or what you thought it was doing) that got you there in the first place.
Sometimes simply applying full control deflection won't recover the situation; further, under some situations (nose low/high speed) being aggressive with your control inputs can cause greater issues (inducing stick shaker or damaging the aircraft if applying rolling G). In some severe instances a combination of control inputs, trim and power changes are required to recover. For example, nose high but very slow may require you to roll on angle of bank to bring the nose down as full forward stick and forward trim may not respond fast enough to prevent stalling.
These events are very dynamic. I don't personally believe that an autmoated system could be designed to reliably recover 100% of the time without inducing greater issues.
I think the training concept is good but it has taken a long time to be mandated by CASA - thankfully we did a lot of it in the military and were tested on it frequently from day one.
As you would expect was way above average in most sequences. When it came to IF unusual attitude training he really struggled and was actually worse off than most until he got his head around the concept. He later went on and flew C130s though unfortunately I have now lost touch with him.
