Bertie, I'm not too good at explaining this. It isn't the angle of
banking that matters but how fast you roll the airplane on its axis to
to get to the back angle that matters. We've gone thru the arguement
that one can rotate an airplane around its roll axis 360 degrees and
not have someone on that axis feel anything but 1 G into the seat.
This is different -- someone else ran the numbers to show what happens
to the local G sense as a function of how fast the airplane
accelerated into the roll -- we'd have called that alpha with two dots
above it back in the long hand calculus days. Accelerate into the bank
angle too quickly and if I was sitting far from the roll axis you'd
lift the wine from my glass. You would, I promise, need a locked
cockpit door if you did that.

I'd be at whining over spilt wine.


Just my two cents. I'd agree that any pilot would fly smoothly and avoid
jerking the controls. The issue is, as far as I can see, more about
turbulence-induced roll motion such as in windshear and wake turbulence. In
those situations there might occur large roll accelerations, both when the
gust hits and when the pilot has to correct quickly with large control
deflections.
I found a B767 pilot report which stated:

" We entered an arbitrary working area into the Honeywell Pegasus FMC and
set up for some flight maneuvers. The first was a check of roll rate in
bank-to-bank rolls from 30 degrees to 30 degrees at ½ wheel deflection.
Flying the clean airplane at 350 knots, bank-to-bank took 4 seconds, for a
roll rate of 15 degrees per second. Here is where a sharp control input
initiated an aeroelastic response from the airframe. A later check of this
same maneuver with flaps 30 at Vref=136 gave a bank-to-bank time of 6
seconds, or a roll rate of 10 degrees per second. This excellent response at
slow speed in the landing configuration is another indication of the
exceptional handling qualities of this airplane."

So in the first case the average roll rate was 15 degrees / sec. I guess
someone with fresher math / physics knowledge can estimate the instantaneous
start/stop g-forces from those numbers. To me this looks like your wine
might stay in the glass, but Mx at the wingtip may have a hard time hanging
on.
