Upset Prevention, Part 3

Airbus’ flight testing demonstrated that if the pilot tries to counteract the first rolling motion, these control deflections will roll the aircraft into the vortex, placing it onto an intercept with the core of the vortex. Worse yet, when the aircraft enters the core of the vortex, the rolling motion will be amplified by the pilot’s initial inputs. The result will be a final bank angle greater than if the pilot would not have moved the controls.

This is the final part in a three-part series on upset prevention. If you missed them, here's the first and second parts. Airbus sought to better understand the causes that would lead to longer-lasting and more-severe wake encounters. Most of the encounters were performed stick-free--in other words...
