I am comfortable with the redundancies designed into FBW systems, that is functionally. I take issue, though, with a computer programmer acting as PIC in my stead. There should exist, on the yoke, a kill switch to disable all the magic. I can't believe that the response to an accident attributable to software is to "fine tune" that same software. What about the next time an AirBus pilot finds himself in a situation that the programmers hadn't forseen.
