G-Force (aka Gatchaman)

Need info on Blue Angels and G-Force. What do they usually pull?
Its my understanding that
"The Blue Angels are trained to ward off G-forces without the help of G-suits, garments with air bladders that repeatedly deflate and inflate to help maintain blood supply to the brain. The suits' movements would interfere with the control stick between a pilot's legs. "
What is the maximum they can handle? When taking a reporter on a flight, what is the maximum G they would do?
I could drone on about the friends I have who have flown with the Blues, show stories, combat stories, etc.
But I won’t.
Fact: they do Not wear g suits.
From the Blues official FAQ:G-suits are designed with air bladders (pockets) that inflate and deflate to keep a pilot’s blood from pooling in the pilots’ legs while executing sharp, unpredicted combat maneuvers. Unlike combat flying, the Blue Angels demonstration pilots know the maneuvers they will fly prior to execution, so each pilot knows when one will be experiencing heavy gravitational forces. Anticipating the changes in gravitational forces allows the Blue Angels demonstration pilots to combat G-forces with muscle contractions. Additionally, G-suits would detrimentally impact flight safety.The Boeing F/A-18’s control stick is mounted between the pilot’s legs. The Blue Angels have a spring tensioned with 40 pounds of pressure installed on the control stick that gives the pilot a “false feel.” This allows the pilot minimal room for un-commanded movement. The pilots rest their right arms on their thighs for support and stability while flying. Therefore, inflating and deflating air bladders in a G-suit would interrupt this support and stability, causing un-commanded aircraft movement.
As for Gs...
Standard show the will push 8+ in some places, but not for long. Most riders get queesie around 3 or 4. They won’t generally exceed 7g with passengers in no 7, but they have been know to take no 7 up with a VIP for a full show.
nominally the hornet is rated at 7.5 G's. The G suit only buys you an extra G or so, if you are a well trained pilot. The Blues spend lots of time in the gym specifically working on their stamina for G tolerance.

So if a news person, not wearing a G Suit or oxygen mask, claimed to have pulled 9Gs (and not passed out) with the blue angles....chances are they are full of BS?

Who is claiming such?
Is the news person named Brian Williams?

Hardly the point, but since you bring it up, even a momentary high G incident can cause unconsciousness. At least one of the prop trainers back when were notorious for this being capable of this.
Regardless, I was responding to the outrage of the other guy at the idea that they did not wear G-suits.
The hornet has a limit of 7.5 G’s. Anything over that would be an over stress requiring a maintenance inspection. I think they actually put g suits on the passengers for media rides. One of my buddies from flight school did the narrator/opposing solo track with the Blues.
Transmute!
9 G’s is possible with the thunderbirds. The slick configured F-16 has a 9 G limit
No news person is going to pull 9 Gs with or without a G suit.
The Blues can do their entire set of maneuvers without exceeding 5 Gs, although they occasionally pull a little harder to turn a corner to make up some timing.
Even a trained military pilot on average needs help over 5 Gs witha G suit.
F 16 pilots will often pull up to 9 Gs with G suits and vests and special body maneuvers squeezing their diaphragms to keep blood in the chest cavity and head. They have stilted seat to increase tolerance.
Nobody is pulling 12 Gs.
Wearing a G suit does not interfere with flight controls.
Demonstration pilots trim nose down so that there is always a pull force required on the stick and all control movements are in the same direction, pulling, more or less as required. That allows more precise control than neutral trim which would require pushing and pulling around a null point.
Pulling Gs makes pilots handsome and cool and girls delirious.
The most common aircraft for GLOC in the Navy has always been the primary training platform. Experience plays a huge factor in avoiding GlOC
so was i, but yes, i did forget a prop plane accident of such style.
I do recall that there were a few of those, for some not keeping track, at a few of the air races in Reno, in times past, too.
History discounts the fact that, during WW2, anything newer than a Grumman F4F, or a Curtiss P-40, started having a bit more speed and agility, which adds to more G-forces upon the pilots and airframes, too.
Um, even for those who were the radar techs, after an intermittent short, under a kick panel, that never occurred in the flying straight and level of an F4, and the only way to chase it was to ride in the back seat with the panels removed to watch for a loose wire, while jinking about, and attempting to stay out of the way of the other control stick in front of you, which moved as the pilot moved his control stick in the jinks.
That did cause a mess to clean up, um, with “more places for stuff to run into crevices, etc.”
dear door,
yes you may.
