Dinosaur sir,
You will need to re-read how Alt 1 and Alt 2 differ.
Your forgetter is working too well.
Hi Turbine D, Assuming Bonin was right-handed, then he would have been using his stronger arm to fly the aircraft. This made it easier for him to jerk the aircraft around initially.
A number of Airbus pilots have remarked in the past that it would have taken a lot of work to make the lateral control inputs that were made due to the viscous damper in the lateral channel. I suspect that his arm was burning with fatigue after the first 30 seconds and that his ability to make small corrections was then compromised as a result.
