So here we go again- he asks an apparently innocent question, and then
argues with all of the helpful responses from experienced and knowledgeable
pilots. It's getting boring, although MX bashing is developing into an art
form.

The fact is- flying largely relies on visual cues, not vestibular (applies
to VMC flying). Of course, all of the aviation physiologists at flight
surgeon school could be as irrational as MX, but not likely.

After flying many hours of acro, I've never wondered where my head was! It's
all about coming out on axis, the right attitude and altitude- and you put
your head and vision where it's needed to see that the other stuff is right,
nothing more.

IFR flying on the other hand, particularly at night, is another story. Then,
of course, the focus is on the instruments, and needing to ignore any other
cues.

My most memorable example of this was in the centrifuge at FS school. We
started from 1g sitting still, to around 1.5g, but with the bucket now at 90
degrees. It was a strong sensation of getting pitched forward and inward. At
least I was able to do the 9g ride without a GLOC, and this is what it's all
about.

Who cares where one looks when all he's doing is sitting in a chair, and his
only option is to look forward at the screen? It's kind of sad and pathetic,
although annoying as well.
