High G...It Takes All Kinds

A buddy of mine used to open his airshow act with a 13 turn INVERTED SPIN. We asked how he manged the negative G. He said that on about the 10th turn he began to red out so he squinted like hell. The hard pullout at the bottom "got things in balance again".
Another good Canadian friend who performed a solo routine in an F-5 Northrop would enter the show parallel to the show line in afterburner, rack the airplane into a vertical bank turn and pull 7.5 G all the way through a 360 ending up in front of the crowd contiuing the same line as he entred. He and his cohort did this without G suits. Jake said that he began to gray out as he came around to finish the 360 and " gathered things up" as he was climbing away from the field. Lots of grunting and tightening up but to no avail. Three years later he failed his medical due to internal damage. He told me that he could not stand the G suit.
I have mentioned in the past flying a full routine with Fred Ludtke in his Monocoupe doing his " Four and a Half G for Four and Half Minutes' and it does wring you out when you're not doing the flying.
Betty Skelton also had to quit her aerobatic shows because it was hurting her and I wonder about Patty Wagstaff who I think is one of the greatest I have ever seen.

 

I don't exactly know what damge but protracted heavy loads on the mesentery's that hold other things in place can cause problems. The heart and blood vessels and blood vessels in the brain take a pounding in constant high G exposure.
My late friend, I'll call Jack( first name) performed an outside loop in a Bucker and landed with a huge blood blister on his forehead......a small aneurysm. Twenty years later he did have a brain aneurysm. I'm not a physician but I know of several cases where pilots have had to stop heavy flight maneuvers. Russ , SNJ5 could tell us all about it, I'm sure.

 

I'm not trying to pass myself off as some kind of expert on what High G does to you after too many years of it. I have just passed on what I was told by the individuals who have done it. having been to 4.5 and 5, I know that it does something to you that ain't natural or good.

Chupa, By all means get some aerobatic training ! What we are talking about is hard heavy loads that you would never experience. Those of whom I spoke were taking far more G forces than you or I will ever see. You probably won't get more than 2G to 3G at the most and the training will make you a complete pilot. I am a firm believer in spin training as a minimum but if you learn a few of the basic maneuvers you won't freeze if something turns you upside down or you get into an unfamiliar atitude. It is a heckuva lot of fun too if you are in the right airplane. GO FOR IT.

I am not sure what they teach now or how they do it but I would imagine that loops, spins, barrel rolls, and if the airplane is suitable, slow rolls. Learning to roll on a point is a great training exercise. Before I soloed my instructor had me doing loops and spins and lazy eights. I felt comfortable with the airplane when I did solo. Nothing that you will ever do in the advanced maneuvers will stress you or hurt you now no matter how much you do. It's the those airplanes that are powerful and heavy enough to run the G up to 6 or 7 and you will never get there unless you end up in a jet fighter.
I heartily recommend some aero traing.
Sounds like you are doing a good job of your training so far so keep flying!
