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.



Yes, I understood that and that was what I was adressing. If you were 25
feet from the roll axis ant the rol rate of 10 deg per second was
introduced smooothly, you'd rotate a bit under five feet in that second,
less than you would if the airplane was rotated on it's pitch axis at
even a third that rate if you were parked in the front or rear of the
airplane.




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.

OK, put the stun gun away, or aim it over there at the other widebody
and frequent poster here.



Well, I have only Anthony's frequent postings to weight loss froups as
evidnce of his widebodiedness, but..
