Then let's say there is accident, where the autopilot failed and the pilot's could not fly the aircraft properly manually and crash. Is that not pilot error also? Due to lack of handling skills? Which is what will happen with these bizarre policies some companies unfortunetely have. Yes of course, pax comfort, safety and all. Still you have to be in shape with flying manually so then you have to practise that.
And landing manually with autothrottles on I find very strange. But then I do not know the Airbus as I am a Boeing man.
Fortunetely my company does not have a policy regarding manual flying vs autopilot.
