Ain't no such thing as a 1 G roll... 1 G is is sitting motionless in
your chair with your arms on the arm rests... Any perturbation
(physicist jargon for shake rattle and roll) from that requires
accelleration of mass, which translates to G forces.. Just raising
your arms off the arm rests to reach your keyboard requires
accellerating tens of pounds upwards, which thrusts your mass downwards
into your seat bottom, into the chair, into the floor, to the center of
the earth, and you are no longer at 1 G, even if momentarily...
Now ignoring the sideways G loads from the rolling moment, just
beginning a roll in the aircraft requires swinging the pilots mass in
an arc... Taint 1 G anymore... Just ask the rock on the end of a
string...
It's a poor physicist that thinks it is a 1 G roll... I might call it
a Low Gee roll, perhaps, but not a 1 gee... Smoothly done, a roll does
not have abrupt changes in perceived G load, and so is thought of as a
1 G roll... Yet, they overlook the fact that when inverted they have
to have +1G simply to neutralize the -1G from being inverted in the
gravitational field, and another +1G to retain the sensation of normal
weight into the seat of their pants, so they are actually pulling 2G at
that moment...


denny ... who took physics long, long, ago in a world far, far, away,
when logarithms were looked up in a table, and the only 'calculator'
you had was your brain and a fancy pair of rulers ( slide rule..)
