The middle would be by far the most comfortable seats on the plane. Those
window seats are going to have a interesting ride.


The way I see it, only the vertical accelerations resulting from bank
initiations may possibly be objectionable to passengers. The rate of
bank initiation is under (auto)pilot control, so theoretically it
could be kept below that threshold.

Do you see ride quality problems in straight and level flight for
passengers seated well displaced from the longitudinal axis of the
aircraft?

There's a big difference from being displaced 10 feet from the center of a
20ft 747 cabin and being 40 ft from the center. And sure the (auto)pilot has
control of the bank but he still has to land and I've been in wide body
airliners that did a significant amount banking on final during bad weather.
If you build a new aircraft that is limited more than current airliners to
the weather they can land in a lot of the fuel savings is going to be lost
when they have to go around or divert while all the other planes are
landing. It won't take many of these to make people not want to fly the new
airplane.

I wonder if a version of this plane could use fly by wire to change the way
the plane turns, a bit.

Could they have the plane do a bit more of a skid though the turns to
eliminate, or mostly eliminate the up and down of the banking for the
passenger's comfort? A little more lateral G would be better, I would
think.

What "up and down" are you talking about? The acceleration vector is the same
for everyone.

You really are completely clueless, aren't you?

Perhaps thay should consider rotatable landing gear (such as used in
the B-52). With that the plane could land in a crab, making banking
largely unnecessary.

What difference is that?
