THAT is a great example of an accelerated stall. ASI is up at 109-110, while it's pulled into a pretty generous angle of attack. The AOA gauge is a fantastic way to watch for stall proximity and how much you're angling into the air before the idiot-light stall light and horn come on. Watching the AOA gauge and flying by it means you will always be inside the envelope and rarely finding a stall you didnt expect.
Here's a couple. CTJ on approach, w/o flaps, just getting too slow, both the analog AOA and the pie graph show how deep the alpha angle is, and you do have to be at stall imminent for the pie to go red, straight and level, just forgetting flaps, getting slow, and the pie goes from green, to yellow, to red, the horns start, while on the analog AOA gauge you can see the alpha angle degree #. In x-plane at least the aoa is relative to the long axis of the fuselage so when flaps are lowered and the wing angle changes it levels out the fuselage angle and the fuse angle / aircraft angle gets more moderate compared to relative wind. The second one is LJX in an ~85° "steep turn" on auto throttle 180kts. holding (as best as possible) 0 vertical rate, +/- 100fpm level turn.. normally tested for PPL is 45°, for commercial is 60° (and even in a 200hp arrow, holding a 60° steep turn requires full power and may and I believe does erode speed). There's a very generous wiki topic on stalls which also covers accelerated stalls. which one example being at 2g (standard plus one more, because life exists at 1g), I think is at the 60° steep turn angle, stall speed # is 1.41x. well specific "g" aside, it's a fascinating concept, and makes an AOA gauge as directly second nature as the vvi itself. The LJX ~80-85° bank angle steep turn, at ~200' agl, 180kts... you can see is pulled into strong backpressure generating an aggressive alpha angle, which at ~170 knots is on the verge of an accelerated stall
- "slow flight" stall appearance, level and deepening angle of attack to stall point
- "steep turn" ~85° high power, high speed, accelerated stall
