mmm, not so sure, the physiology of the human body is such that the brain
needs that blood! While modern G suits help to limit the surge of blood to
the feet they cannot totally stop it. Also the human head head weighs
around 4 - 5 kg. At 9 G the effective weight is 36 - 45 kg. That does not
take into account the additional weight of the helmet. That is some load
through the neck, come to think of it is is like 1/2 of me being on my own
head with no support, ouch...

I still think that the human is the limiting factor.

Modern G-suits allow much higher G-forces, so the pilot should not be the
limiting factor.

How indicative of maneaverability are the max G numbers of fighter
aircraft?

Also, most new aircraft have reported max of 9Gs. Why are they all
coming out at this same number?

Modern aircraft are capable of higher G turns; however, in order to
stop the pilots from blacking/redding out and/or dying in their
seat, the computer controlling the fly-by-wire / fly-by-light
systems stops the turns going any higher.

I think

It could also be because they do not want to release into the public
domain
the exact performance of the aircraft? A few years ago all aircraft
seemed
to be listed as Mach 2.2 at altitude??
