Why is Rolling G dangerous?
In another lifetime I flew the Australian Wirraway trainer, which looked like a Harvard. I recall it could take a very high G loading.
On our Pilot's Course, we were taught how to carry out flick rolls by simply yanking hard back on the stick at cruise speed of 120 knots and around we would go. The stress on the Wirraway must have been significant but there was no prohibition on the manoeuvre.
Later on we were told about the dangers of applying "rolling G' where normal G limits were lowered. In fact we lost a Wirraway during an air to ground gunnery exercise where one wing folded when the pilot pulled out of the dive and banked around the same time.
Can someone please explain the dynamics of rolling G and why the manoeuvre can be dangerous. During flight simulator training for unusual attitude recoveries in the 737 simulator, we often see pilots hauling back the stick during a dive recovery before they have first levelled the wings.
