I rarely use autopilot/autothrottle below 10,000' unless I have high workload
Really? At what stage after take off do you disconnect the autothrust then?
A lot of people on here said that a majority of commercial pilots would have been able to land on the Hudson back in January 2009. I very much doubt that. They would have engaged the autopilot and flew the entire descent down automatically.
No they wouldn't, if you had as much Airbus experience as you claim then you would know why...
