Coördination stops lateral passenger movement. It does nothing for up and down. (Coördination is also about more than comfort. It keeps the flow attached to the wing. If your passengers are slipping, so is your wing.) In a roll, with a tubular fuselage, everyone—pilot and passengers—feel about the same vertical Gs. OP’s point is in a flying wing, the folks on the tips will lift up or drop down relative to the pilot and thus experience extra Gs.

My response is (a) this can be controlled in avionics and training, i.e. don’t do that, and (b) now that I think about it, vertical Gs aren’t as sickening as lateral ones.

Specify a maximum roll rate in training and normal-law software and this problem is solved

I’m wondering whether there are major airfields with traffic patterns that require roll rates that would exceed whatever maximum is desired for comfort. My intuition is that the situation would be tolerable at most airfields but that normal-law limits that are too restrictive could be dangerous.

A few years ago, I would your use of diaeresis an admirable quirk. But now, especially given the em-dashes, I'm wondering if you're an LLM overtrained on the New Yorker.
