What is the maximum number of?

Question

Gs in a plane aerobic show can a body can withstand. Thanks.

Answer 1

8g-11g, depends on your body i guess.

Answer 2

I have seen 11g on a g-meter,

Answer 3

With a G-Suit and high tolerance training some pilots can make it up to 11g's.  The world record holder made it to the high 12g's before passing out.

Answer 4

6 Gs are considered within the thresh hold of most trained aerobatic pilots.

Momentarily 11+ Gs can be pulled, if within the limits of the aircraft, with no adverse effects on the pilot.

Answer 5

It is safe to say that without special physical training and flight suits you would pass out in the 6-8g range.  Without special training and with a special flight suit you might make it to 9gs.

Almost certainly you will need both training and flight suiting to withstand anything more than that without the blood rushing from your head to your legs and you passing out.

Answer 6

Although it varies from person to person, day to day, the average static threshold for G tolerance without the aid of g-suits or anti-G straining techniques is in the mid/high-4G range; i.e. if you did nothing and just sat there while the G's crushed you, most people lose consciousness around 4.5-4.75 Gs.  G-suits add about 1.5 G's of tolerance, newer "combat edge" systems add about another 1.5G's of tolerance, but the anti-G straining maneuver (called "hook" or "hick" for the sound you make when squeezing your musculature properly) can get most people into the 9G range easily.

However, G tolerance is dependent on both physiological factors (eating, sleeping, hydration, individual characteristics, etc.) as well as training, conditioning, and experience.  It is also highly dependent on G-onset rate (how quickly the G's came on) and time spend under G.  Obviously there is less useful conscious time available at 9G than there is at 6G.

Agree with the above that there is no magic number.  I think the world record (Guiness) for sustained force, vice acute point-stress, is around 82G for .04 seconds on a water-braked rocket sled, but you can research that easily.
