I just saw a show on the Wings channel ...
In an Extra 300
The female pilot said she does
9+ and 6-
at Oshkosh.

That;s probably PattyWagstaff. What she does is a bit out of the ordinary
for competition aerobatics.

I would be surprised if someone pulls more than 4.5 Gs positive and -3
negative for advanced competition, much less for Basic/Primary. I've only
flown basic and sportsman, and there I was pretty much only doing +3 Gs,
and -1 negative (upside down.)

Get suprised. We do not compete and we still hit +6 G's. I prefer not to
get much negitive though, only around 2G's. We exceed 4.5 in simple steep
turns.

After a bit of research I found out who it was.

"Northern Lights Aerobatics Team"

"Michele Thonney, 31, of Lausanne, Switzerland, the only woman flying in
a civilian aerobatic team."

A quote from a Northern Lights Aerobatics Team member
===========
Mario and his colleagues pull as much as 9.5 G's during the show. As
far as negative G's, or the stomach-churning sensation of feeling
yourself falling toward earth fast, tolerances are more limited. "In the
show we go between minus 4 and minus 5,' Mario explains. "By minus 5 it
hurts. I've never gone to minus ten and I don't intend to."

Just doing the Sportsman sequence, my G meter shows +6 / -1 when I'm
through.

Another data point. I fly intermediate in a Pitts S-1T and I pull 6G's
on just about every pull. Negative G's are rather light in
Intermediate because the worst we get is an inverted turn of about
-3Gs or so.

Higher G's are not so much of a problem because the duration is
shorter.
The real question is what is the "G * seconds" that you are
experiencing. 2 G's
for a minute will knock you out just as readily as 10g's for a second
or so.

Anyway, you just get used to it with time and practice ... its quite
remarkable how a normal person can acclimatise to it.

Peter

Advanced pilots routinely get +6 to +8 and -4 to -6 (depending on how
aggressive they fly. I usually have +7 and -5. When I flew Unlimited in my
S-2A I actually had less since pulling to many g's bleeds off too much energy,
and you need every bit of energy to get through an Unlimited sequence in an
-A.
