[PSUBS-MAILIST] Prone pilot position

[Michael B Holt <tlohm@juno.com>]

It's a quiet day, so I dragged out old books to look for stuff
I didn't expect to find.   I started with 'prone pilot position'
in "Human Engineering Guide for Equipment Designers,"
2nd edition, by Woodson and Conover.  1964.

Page 2-147 has an entry.  I quote the entire explanation:
========================================
	This type of seating is designed to offset 
G-force limitations of the human body.  Proper 
angles are necessary to allow the pilot to 
manipulate  controls, see where he is going, and 
provide maximum comfort over extended periods 
of operation.  Special supports for the head and
neck are required to relieve the strain on neck
muscles.
========================================

There's a drawing, too.  It shows the torso angled 
at 30 degrees from flat.   The angle between the
upper and lower legs -- bent at the knee -- is 
130 degrees.  

Just looking at it, it doesn't really offer any 
reduction in cross section.
