We get used to the sensation of pitch from pressure in our back and butt which agree with the ADI. In the real world, with an unexpected acceleration from full TOGA power and a light aircraft - then there can be a sensation / visual mismatch which can cause confusion
Golden R, All of that is known and is supposed to happen to all pilots and yet literally hundreds off GAs are performed all over the world without a problem. How is that? In fact GA is considered so mundane that even a report is not required. And then we have a fatal GA and SI appears almost as an obituary. And every time the nose is pushed down to a bizarre -40/50° pitch. Nobody ever stalls by over pitching. Centaurus has raised a good point. Are some humans more human than others? Is it not always a wrongly executed manoeuvre that opened up a Pandora's box of human factors? Knowledge of SI is not going to help unless it is imbibed that a pitch input must be made by looking on PFD and not by feeling.
