> That's the problem. When passengers are seated too far from the axis of rotation they're in for a nausea inducing ride.
What if the seats far from the axis of rotation faced sideways instead of forward? People don't seem to be as affected by pitch changes as they are by roll changes, probably because we are get a lot of exposure to pitch changes whenever we drive in a hilly area.
The angular change is negligible in either case. The problem is you're ping-ponging vertically. For example, a 3 degree bank correction in an aircraft with a 70 meter wingspan will move each wingtip by 1.3 meters vertically.
In the picture, the passenger cabin appears to be using only 1/3 of the wingspan, so the vertical movement of the outermost passengers (in the last row) will be much smaller than the vertical movement of the wingtips.
A last row width of 25m is much wider than the 5m of a conventional aircraft, but much smaller than 70m.
