BEA have actually done a fine job and having found the FDR and CVR have identified the causes of the accident. This happens to be the flight crew sad to say. Attempts to involved the machine are just grasping at straws and filleting our shoals of red herrings. I like some of the mechanical explanations of the processes but these are not causal factors. Causal factors are lack of CRM, poor training (especially at altitude - as Lonewolf50 and Machinbird have ably identified), company culture, failure to follow SOPs, poor cockpit discipline, no designated pilot in charge when the captain left the flight deck, need I go on. The Air France safety audit which was linked a couple of threads back should be essential reading for everyone wishing to comment. It provides all one needs to know about the causal factors in this accident. BEA are attributing responsibility to the flight crew because that is where the responsibility is. The causal factors are all human factors NOT machine factors. Even the UAS was curable by waiting and following proper procedures. These were not followed and disaster was the result.
