Megan,
Not a story, but a fact, said FOI wanted the SATS c/b puller. The head of training refused, which had calamitous consequences for his career. It was Avtex Aviation at YSBK. There were some "interesting" discussions about "the law" versus AFM limitation.
"We" finally had the Type Certificate holder in US write a letter saying that such a manoeuver was absolutely prohibited, except in test conditions, with a spin recovery parachute fitted.
As fate would have it, due to an inadvertently not reset SATS c/b, a Norwegian Metro was lost on a training flight in a deep stall ---- a hard way to prove the point.
I my opinion, to this day, it is unlikely that the FOI involved understands deep stalls in a T-tail aircraft.
Tootle pip!!
