Pattern Altitude
He got his Cirrus, now he thinks he is a fighter pilot!
Another thing I would never do is post a video of me banking a plane at angles expressly prohibited in the POH on the internet.
Did not specifically see any overstress here, but go honking back on the yoke in a 90° bank and it's fairly easy to exceed Normal Category g limits.
There is NO WAY he didn't exceed the 3.8G limit as I didn't see any altitude drops in those turns. I once had the pleasure of doing similar turns in the Extra 300L Chip Gibbons used to own and we were pulling over 6G.
I yield to your expertise and stand corrected!
Not that experienced at all, but that day we were pulling ~80 degree banked turns, and they were consistently in the 6G plus on the G-meter.
I would nearly guarantee you that they were not pulling 6+ here. It's hard to tell on video how hard the maneuvering really is. I don't know about the Cirrus, but most aerobatic airplanes will not sustain 6G in a turn. There is just too much drag induced. And 6G is not a casual number in most aerobatic airplanes, even for seasoned aerobatic pilots.
Anyone who thought this kind of video would be cool is not very experienced. Assuming their experience level, they were way too casual to have been pulling 6G. I've pulled 6G plenty of times for short duration pulls to vertical or pulling from vertical lines. You're smashed down pretty hard and you'll start going gray after a few seconds. For non aerobatic pilots in airplanes with upright seating, 4G is a large number. Most recreational acro pilots don't pull more than about 4G.
My guess is that their airspeed was slow enough to let the turn come through quickly, and it's too hard on video, especially given the very uneven terrain to truly deduce that they were making honest level turns at 80 degrees of bank...which would require 6G. I'm fairly certain they were flying more of a parabolic profile through those steep turns - not maintaining altitude with that kind of G. My guess is that they pulled no more than 4G here.
I am doing 4 hours on Sat (hopefully my last w/ the CISP)
Then for the first time since the dawn of aviation, I am putting 4 full grown people in a single engine plane Sunday morning and flying somewhere.

Clearly that's not 6PC. He hair is way more gray.

I would be amazed if it even got to 3 G's... Done smoothly, those steep turns while loosing a small bit of altitude could be done at around 2.5 G's..

Not wearing a chute is what might get them in hot water.. Altho the plane is wearing a chute so that could make for a VERY interesting debate at the FSDO.........
Didn't a couple of renters crash a Cirrus doing these kind of maneuvers a couple of years ago. I think they were brothers and filmed everything they did.
