(1) Increasing positive g forces move
activating weight down
compressing a spring, opening
demand valve, and initiating
inflation of g-suit at approximately
2g
NOTE: Maximum inflation occurs
at approximately 6 g; 6.5 psi.
(2) Decreasing g forces allow spring
tension to move activating weight
up, opening exhaust valve and
deflating g suit
