    Depends on how you define state of the art. If your objective is
to optimize safety there are some that would argue that automation is
not necessarily making things safer. What it is doing is making things
cheaper and lighter.

    What bothers me is not having a FBW. Flight management however
when taken to the extremes of Airbus where it not only manages it
enforces I find it very disturbing. Since it is very difficult if not
impossible to get all of the conditions correct in the software it
would seem prudent to simply advise the pilot instead of limiting
his actions.

    I also find the lack of feedback in Airbus systems to be a
poor design choice. So much useful information can be obtained
by the feel of the controls the only reason I can think of for
eliminating it is weight/cost savings.
