Bernt,
One of my best friends in life is an Air Force Lt. Col. who also is an ATP with American Airlines, and he did his master's thesis on the myriad of issues with Airbus design philosophy that has created situations already where automation could not be overriden by the PIC during an emergency situation. A Qantas Air flight experienced a situation where the systems kept trying to force dive a jet and the PIC had to wrestle the aircraft back under control multiple times and reported each time the jet's automation was literally fighting him doing this. And, he reported that he could not override the systems so that he could manually keep the jet on a safe attitude. He reported that he felt it was a very close call with him keeping the jet aloft and avoiding entering an unrecoverable unusual attitude.
Many experts have written that the recent Air France loss over the South Atlantic had its roots in the same issue. While I don't recall the exact situation, I remember there was another total loss with all souls onboard where accident investigators have reported the same issue may have caused that jet to be lost.
One of the factors behind USAF pilots favoring the Boeing design over the Airbus entry with regard to the replacement to the KC-135 was a view of the design of the automatic systems in the Airbus entry making it harder for pilots to perform manual maneuvers such as the emergency breakaway. That isn't speculation. I'm reporting what the AF pilots reported in their recommendations.
So, while I respect you tremendously and consider you a good friend, please don't try to assert that there are not documented concerns with regard to automation acting in manners that cannot be overriden by pilots. I respect you if you disagree and believe it remains your right to disagree. But, there are a lot of professional pilots who have carefully studied this issue and reached the same conclusion I have reached that already we have airliner designs that have put the automation at too high a pyramid where pilots cannot override them when it is deemed the automation is causing a risk of mishap.
Respectfully submitted,
Ken
