I understand.
My g workload doing demonstrations in WW2 type stuff was nowhere near what
you guys flying unlimited maneuvers have to deal with, and even in the
Pitts, my routines were tame compared to the stuff the guys are doing today.
I've always believed that when it comes to acro of any kind, physical
fitness is the key; then working into the schedule slowly and maintaining it
through practice to keep the body acclimated.
Coffee was a killer for me on the negative side. Gave me a headache every
time. You might want to have your blood pressure checked more often too.
I found that if I was anything but totally calm before a flight, doing a
hard routine starting with any raised blood pressure at all would cause
problems.
If you're keyed up for the flight....and in competition....that's a common
occurrence really.....or keyed up while flying through heavy concentration
on positioning in the box, sequencing, or anything else for that
matter...this could well be part of the problem.

Hi Dudley,
Thanks for your response.I´m well aware of the effects when transitioning
between negative and positive g or vice versa and avoid it when possible.
However, my problem is a different one, but I should have explained my
type of flying a bit more detailed, sorry! I´m flying unlimited glider
aerobatics, which means I have only so much energy to spend per manouver,
that´s why some of them need to be flown quite hard...
Currently I´m training negative stall-turns/hammerhead turns (negative
entry, negative exit), negative tail slides (negative entry, negative
exit), negtive flick rolls on 45° down line etc....When I´m flying like 6
figures (between -5.5g and -6.5g) of the before mentioned on a series of
three flights, I can expect to have headache and \"red spots\" in my face.
However, a regular unlimited sequence with just one or two hard negative
pushouts doesn´t affect me at all.
I have trained my positive g-tolerance over the last two years from around
6g to over 8g with no further problem, but Í was unsure if the same is
true for negative g´s.
Anyway, thanks for your feedback!
Best regards,
Markus

Hi Markus;
I take it you\'re flying something that can develop a high g RATE either
way?
Anyway.....negative g takes some getting used to. One of the big danger
areas for new pilots...and indeed for some of us \"old timers\" as well,
(if we\'re not in good aerobatic shape) is transitioning from positive to
negative or the other way around. Avoid this for a while at least. I
always advise pilots, especially demonstration pilots, to stay on a VERY
good health regimen if engaging in negative/positive...positive/negative
maneuvers.
Getting back to your issue; just work into it slowly. That\'s the
\"secret\"
to
building up negative g tolerance. You might practice from level flight to
a half slow roll, followed by a push up starting easy to where you can
take it comfortably, then rolling off...increasing the negative up line a
bit further by allowing a nose low entry for extra airspeed before the
push each time until you can make it around comfortably.
I always advise going UP for negative g acclimation practice!! :-)

Hi,
I wonder what you have to say about how to train myself to better cope
with negative g´s!
The problem I have is, that whenever I do a series of (hard) negative
manouvers (say between -5 and -6.5g) I get headache and my face shows a
zillion of small red spots (bursted veins) which disappear again after a
day or two. I read an article from Patty Wagstaff, where she speaks
about that, but leaves the answer whether or not this is dangerous to my
health in the long term open. I´m not doing this too often (fly a whole
sequence of hard negative manouvers), but right at the moment I need to
train it quite a bit and so I don´t have much of an option...
Please let me know what you think!
Regards,
Markus
