Your gee toward the center of the circle is what determines the ft/sec from your flight path a millisecond ago. So stall AoA is great for max lift, maybe gliding, but norrmally comes about at a slower CAS than best turn radius. It's not an intuitive relationship, but we have seen it in many of our lites For example, the F-16 gets best turn at about 360 kt CAS and 9 gees - turn radius of about 1400 feet!!!! . You can get up to 25 degrees AoA slower than that but not at 9 gees.

Without a gee limiter, I would pull for all its worth in a big plane and worry abut ripping the wings off later. Most charts I have seen show overspeed and flutter to be a bigger problem than over gee.

GUms opines...
Never heard of "Gees."
