How to improve G tolerance and prevent g-LOC?
José Barahona da Fonseca
Hi fellows,
Can the pilot adjust the maximum G level through F-16 control
software to a value less than 9g's?
Can you tell me more about G tolerance techniques? What kind of
techniques?
Can the the Pilot improve his G tolerance through physical training?
What type of physical exercises? Jogging?
Thank you for your help and attention.
Bye. Adeus!

Yes, with the load category switch. CAT I loads are essentially
air-to-air loads, and the limits are 9.3g and 26 deg AOA. CAT III loads
are essentially air-to-ground loads, and limits are 6.5g and 16-18 deg
AOA (depends on gross weight). Alos, the maximum commanded roll rate is
reduced in CAT III. CAT II loads and somewhere inbetween and there is no
automatic FLCS mode. You either fly in CAT I and observe the limits for
the specific configuration, or fly in CAT III.

Contracting your muscles in an atempt to keep the blood from rushing out
of your head. There are also breathing techniques involved.

Weight lifting. Jogging too much will lower your blodd pressure, but
what you is high blodd pressure. However, this does not mean that
cario-vascular fitness is not important. BFM will wear you out, so while
you need fairly good strength to help increase your g tolerance, you
also need some endurance so you can fly each engagement without having
fatigue degarde your performance.

This is problematic. High degrees of cardiovascular fitness correlate
with lowered blood pressure and *lower* G-tolerance. If you run
regularly, and your resting heart rate is 55 or lower, you're probably
not going to make a good fighter pilot.
This doesn't mean that you get to be a slug, though. (Slugs are
different from fighter pilots in that you can tell something to a
slug.) You need a reasonable level of CV fitness to maintain a
reasonable level of endurance.
There were a few articles in the Naval Aviation mags in the 1980's
that suggested progressive weight training to build strength and
muscle density/mass were the way to achieve high G-tolerance. I have
no idea whether this had any clinical basis, or whether it represents
current thinking on the subject, but there was certainly some
anecdotal evidence to back that thesis up. I personally knew guys
who claimed to have raised their G-tolerance by 1.0 or more by
training 2-3 times per week with weights.
I decided I'd rather ride my bike than lift, so I went S-3's. Max
G: 4.5. Even I could handle that.

Frequent flights with high "G's" such as acro increases tollerance. If
I haven't done arerobatics for several munths, although I know how to
strain, my "G'" tollerance goes down. but gradually goes back up after
a couple days.

LOL. Good analogy. :)

I have noticed the same thing. Most of the flying I do (flight test
enginner) is in the C-5. However, I also fly the T-38, and most of the
testing we do is structures related (ie put some strain gages on
something and go out and pull some g) and after being out of the cockpit
for awhile I can definitely notice the difference.
