Well, Doug, that makes perfect sense to me. Your inner ear uses not only
angular displacement but lateral displacement to determine "up." That is
why an attitude gyro failure can be so insidious in IFR conditions. If the
A/C is in a very gentle roll or pitch, but the gyro doesn't display it, your
brain says whatever the gyro says is "up" is right; then if something else
makes you return to the real "up", your inner ear interprets that as rolling
or pitching in the OPPOSITE direction! Bad things generally follow very
shortly. (BTW; You wouldn't have the time for this scenario to develop in a
liner.)
Was Vance talking about putting an attitude gyro instrument (a la A/C) in
there or a gyro big enough to control the bike?
Boy, you just never know where these threads will go when they start, gotta
love this list.

Jim, After having talked to Vance Breeze a couple
of years ago and
having sat ( laid down) in his M/C liner I can tell you what
one of the problems
seems to be. It is very hard for your body/mind to realize
how far tipped to the
side you are when you are laying on your back looking just
over your toes. The
horizon is just to hard to see. Lay on the floor on your
back and roll over 45
deg. and your brain thinks everything is fine. Now sit in a
chair and try it and
you know your going to fall over. Vance was going to try
and figure how to use
something like a gyro to help know when it was tipping to
the side. He has
never had the time to work it out.
