Barber Pole Question...Pilatus as an example

[Everskyward]

That sounds like what I experienced (in a much smaller BE35) a few weeks ago. I hadn't done power on stalls, so I decided to try it. Since I was by myself, the plane was really light and I felt like it was standing on it's tail by the time it stalled. Very abrupt, and the left wing drops no matter what you do. It was quite interesting.....

But in our case the stall he did was a plain vanilla clean stall at idle thrust, straight and level. One of the maneuver limitations for the CE-680 is "Intentional stalls are prohibited above FL250. Intentional full stalls are limited to idle thrust only."
