David, the issue for me was 1 g down, into the seat. In a steady state
climb one experiences one G, but if the nose is 5 degrees up that force
is 5 degrees aft of down. My understanding of the question (and it
could not be an accurate understanding) was, can one somehow roll an
airplane without having it experience anything other than 1 g "down". I
think it's been shown the airplane can be rotated 360 degrees on its
axis with the pilot always experiencing 1 g down into the seat. At that
point though the airplane is going downward pretty fast, and the weight
vector would shift forward of straight down.



Tony,

I see where you are. I would say that if that is what you using as a
datum then the 'g' down axis will vary from a few degrees at high speed
in level flight to up to around 12 degrees or more at touchdown in level
flight without any aerobatics at all..

But in your definition it would be impossible to have a flight that
included take off and landing and a modest climb and descent at a strict
'1g' down.

I was assuming a steady one 'g' at right angles to the free stream
airflow!
