Why would you try to do such maneuvers on final? He should have kept going, or done a left 360. Either way he was also probably going way too slow to do such maneuvers, and was way too low to be doing that.

There is a lot of speculation of course. The pilot was on a BFR, the CFI had 0 time in SR-22s.

One theory is the CFI may have initiated a simulated engine out emergency, but we will truly never know.

Cue "how the snot does this happen with an instructor on board?" comment.

When in doubt, firewall throttle, and don't fly like you're in a video game.

Friend of mine had a slightly similar low altitude wing stall on a turbocharged Glasair III. He put the loud handle to the wall and literally hung the thing in the air by the prop for a few seconds, but managed to recover.

I agree, but it does happen. I had a CFI trying out for one of my jobs almost do this to me in our Arrow (non-turbo).

Overshot final, so we're at about 400' AGL, slowing through 80 kias (75 is final), and he banks hard (>45 deg) to bring it back to final AND adds the last notch of flaps all at the same time.

I took the plane from him, poured in the power, cleaned it up, and landed it. When I asked him to explain stall speed as a function of bank angle, angle of attack, and loading -- he couldn't. He doesn't work for us.


And oh yeah: I'm not a CFI myself.

60 degree bank angle, crazy for that and almost any type of normal recreational plane...
