Definitely out of topic, and I was referring to snap roll (Accelerated stall + roll by rudder input) the purpose is to stall the wing abruptly by a sharp input of back stick at a speed well below VA ( And to play safe well below max flight manual allowed flick speed limits) thought don't know how many degrees that would be Though for those interested in numbers its VS x square root of G load, the wing will stall at a given speed and Gload exerted.
