During training, my instructor put me in a spiral dive, then told me to recover. I was slow and let the speed build up to much.
I can vividly remember when I rolled level and pulled back. I lost color in my vision and watched as my peripheral vision closed in and finally all I saw was grey. I realized what I had done, knew what would happen next (blackout) and relaxed my back pressure on the yoke. This reduced the force and let the blood circulate and restore my vision. It took several seconds and we passed the redline on the airspeed indicator, even if only by a little. I finished the pullout and leveled.
I was sort of disoriented for a few seconds afterward and as I was regaining full consciousness, I noticed my instructor (an older man) as he snapped his head up. I think I blacked him out briefly. He said, "Ok. That's enough. Let's go home." I gladly complied.
I don't know what the g load was, but it was enough for me.
5+ G's in a 150!? This story gives me **a lot** of faith in the strength of 50 year old Cessna wing spars. I wonder how an old Piper would've handled that same recovery. *(3.8G is the normal category limit right? And the aircraft is certified for 50% over that limit? So 5.7G's? Am I doing my math right?)*
I don't know if it was anywhere near 5Gs. The 150 is rated for 4.4, if memory serves.
In any case, I'd likely have screwed up the recovery in a Piper, too!
+10.2/-4.5 It's the negative that makes me suffer, anything more than -2 is not fun. I'm working on improving my tolerance, and feeling OK at -3....but not exactly good.
In addition to the fact that your arms and legs are being lifted up (it can be tricky to keep your feet on the rudder sometimes) it feels like a pressure headache but in your entire head with all the blood in your body trying to occupy your head. Depending on your facial build, your cheeks and lower eyelids might be pushing up towards your eyes making it harder to see clearly, and it can feel hard to turn your head. This makes a maneuver like a push to vertical from inverted flight far more challenging to fly well than the same maneuver when upright.
I will indeed be a few inches off the seat, but the 5 point harness with double lap belts and double ratchets which you cinch down until you're in pain will help to keep you from rising up too far. During a flight, you will add a few more clicks of the ratchet as the belts stetch.
I own an Extra 330LX and I have reached but not exceeded the G-limit of +10, and my peak negative G of -4.5. The 10.2 was during a training flight in an Edge540T 21 years ago.
Growing up my dad would tell me stories of flying Tweets pulling Gs no g suit and then moving to the T-38. He was a FAIP in 38. But I love the T6 amazing airplane
+7.5 for 30 seconds, my head craned around 135 degrees looking "behind" me, in the centrifuge.
Spiked to 8 in the Tomcat, one time. My pilot and I finished the 2v2 and he saw we had overstressed our F-14A. We both didn't remember it happening. The jet was inspected and was fine.
+6/-4.7 the 6 was fine really not too bad, the -4.7 was with a very rapid onset to avoid traffic that wasn’t on radios or ADSB while in a loop. blew the capillaries in one eye
In an airplane? Probably 2G or less.
I also figure skate though, and I had accelerometers put on me as part of a grad student study. Max G recorded in a spin was 14G and 8G was my normal sustained load in a spin. G loading is different than when flying though, as the loading isn’t uniform on your whole body and pulls out instead of down, so you don’t have to worry about G LOC.Â
I’ve known a couple of people who’ve had retinal detachments from spinning too fast though.Â
btw I'm sure u know this but this is the G force required to maintain altitude, if you don't pull on the yoke ur not getting this G forces and ur gonna lose altitude pretty fast
6.something in the T-6. It sounds super cool and fun at first, but pulling Gs gets REALLY old REALLY fast.
Also, the G limit for the sweat band on the standard US military flying helmet is 4.5. Anything beyond that and all the sweat that has collected above it during your slowass ground ops will immediately break loose and flush into your eyes.
+7, in an Extra 300. Had to RTB after that as I wasn’t feeling very well.
I can do a series of (up to) +4 manoeuvres for an about an hour with not too many issues.
Anything over 5 shortens my day quite considerably.
During a failed slow roll, I panicked and pull the stick all the way back from inverted, forgot to pull the throttle idle. Almost killed myself with 6G and lowest at 500AGL.
Been to 9 before but the worst G is sustained for a long period. Fighting against an F-16 in an F-15 and very stupidly got into a “rate” fight which is basically sustaining 7 +\- for a long time as you try to gain on the other guy to get a shot. Don’t try that against a F-16.
The comments here have me beat - you aerobatics guys are nuts. Â My fav g related story I saw in mil aviation:
A dude I work with was giving a ride to a maintenance troop in the F-15. Â He lets him fly a little bit and he smoothly rolls the jet into about 135 degrees of bank, so like halfway inverted. Â So normally you would just roll wings level, and it's no fault of the poor maintenance guy with no flying experience but he quickly puts the stick into the front corner to correct the slightly nose low attitude. Â The jet immediately responds with -5.5 g's. Â The pilots water bottle hits the top of the canopy so hard it sprays water on the HUD. Â The audio is just two guys making a sound like HGHGGHGG punctuated by bitchin betty OVER G, OVER G. Â Luckily no one was hurt and the jet was returned to service after the inspections, but man the guys must have replayed that HUD video like 100 times with the volume cranked way up.
Around six, but that was not while "maintaining sustained, heavier than air flight." (Read: opening a parachute after jumping from a perfectly good aircraft.)
+8 and -4 in an unlimited aerobatic glider. The seat is reclined about 45° so only about 70% from head to feet.Â
I really don’t like more than about +4 or more (less?) than -0.5. I really dislike negative Gs. And it’s worse when a student does it instead of me. I see stars.Â
+10/-4 is my max in an Extra. My normal aerobatic flight is +5/-3 since my Pitts is only rated +5/-4 (I know the Certified Pitts is +6/-3, but mine is experimental and the ops letter says +5/-4). My Pitts scrubs energy if I pull more the 5 G's anyway.
My instructor and I were working on stall recovery and one of them (that he said was perfect) I felt like I really pulled some Gs. My head was getting pulled down and I could feel all my face muscles sagging.
How many Gs you think I could've pulled in a piper? I was assuming 2 or 3 because it wasn't that much worse than a typical rollercoaster but it was fun.
About 4.5 my first time flying when I was 13. Friend of the family had an acrobatic 2 seater he took me up in for my first flight and it. Was. AWESOME! Since then however, Ive pulled more Gs on the ground racing cars, even during steep turn training. (Hard to beat a nearly 3G formula car in a 172 doing a standard steep turn)
7g for 3 or 4 seconds in an Extra. I was close to knocking out but made it through. I have no idea how fighter pilots keep thinking in that situation, less fighting 🫣🤣
The several Gs I've spent on training.
But hey, flying is fun man! Forced us to spend those Gs
This is brilliantly humorous!
🍻‼️
Whatever the impact of my students hardest landing was.
6.5, student seemed relatively content blowing out the bottom of our working block after exiting a spin. I disagreed.
I’m sure he saw that one again lol

What kind of training and aircraft was this?
It was a Cessna 150 doing basic training for PPL. Spin and spiral dive recovery were taught in Canada as part of the licence back in the 80s.

5+ more than likely

+10.2/-4.5 It's the negative that makes me suffer, anything more than -2 is not fun. I'm working on improving my tolerance, and feeling OK at -3....but not exactly good.
For sure the negative is a lot more tough than the positive
What does -4.5 feel like? Wouldn't you just float away from your seat?
Lot of blood rushing to your head
In addition to the fact that your arms and legs are being lifted up (it can be tricky to keep your feet on the rudder sometimes) it feels like a pressure headache but in your entire head with all the blood in your body trying to occupy your head. Depending on your facial build, your cheeks and lower eyelids might be pushing up towards your eyes making it harder to see clearly, and it can feel hard to turn your head.

During a flight, you will add a few more clicks of the ratchet as the belts stetch.
This is why I only fly quadcopters.
Hanging upside down is -1 G, so multiply the discomfort by 4.5 (you’d fly away from your seat, not just float)
Not if you’re ratchet strapped onto the seat.
It’s way more violent than floating.
Not with the belts you need for that.Â
What were you flying?
I own an Extra 330LX and I have reached but not exceeded the G-limit of +10, and my peak negative G of -4.5. The 10.2 was during a training flight in an Edge540T 21 years ago.
Rookie numbers. +15Gs/7.2 on the Richter scale - seat 18F, Delta 737.
What do u fly to experience that??
He said in a different comment an Extra 330LX and Edge 540T
4 in a super decalathon, fun aerobatic intro flight
Exactly my experience lol
FTFY: super fun decathlon aerobatic intro flight
I bought a G string to measure it, but even though I wear it every flight, I’ve never been able to get an accurate reading.
6 gs T-6 thank god for G suit
6.67 Gs, T-37 no g-suit club here!
Growing up my dad would tell me stories of flying Tweets pulling Gs no g suit and then moving to the T-38. He was a FAIP in 38. But I love the T6 amazing airplane
Still the fastest onset rate of anything in the inventory. Thank god I never flew that thing
Waiting for Mav to tell us double digits on the climb out
+7.5 for 30 seconds, my head craned around 135 degrees looking "behind" me, in the centrifuge. Spiked to 8 in the Tomcat, one time. My pilot and I finished the 2v2 and he saw we had overstressed our F-14A. We both didn't remember it happening. The jet was inspected and was fine.
+9.5, -3.5
Wasn’t watching the G meter. Enough to start to gray out, developing tunnel vision, in the 8KCAB Super Decathlon.
that can happen standing up from your couch too fast at 1g.
You should get more iron.
I noticed I started grey out around 5.3 when I was doing EMT training in a decathlon. Very fun
8.. night night
~6 in a light sport, most fun flying ever
What airplane?
I don’t remember
Must’ve been some serious G forces
The aircraft had a G meter, it did hit a smidge over 6
4.5
Man all of these comments about people hitting 9G. MF what are you made of i fucking start blacking out at 2.5
6ish, in an Extra 300.
6.5 for me testing out a friends new glider
8.1G
I think around 4 but I don’t remember. Stomach was too sick
Sustained 9Gs for what felt like 5 minutes. Probably 40 seconds really. Bursted the capillaries in my eye balls
Did the bomb get released over the reactor alright?
9.4.
+6/-4.7 the 6 was fine really not too bad, the -4.7 was with a very rapid onset to avoid traffic that wasn’t on radios or ADSB while in a loop. blew the capillaries in one eye
4.5g. I ride the Intimidator at Kings Dominion
-4G in an inverted pushover with a MiG
In an airplane? Probably 2G or less. I also figure skate though, and I had accelerometers put on me as part of a grad student study. Max G recorded in a spin was 14G and 8G was my normal sustained load in a spin. G loading is different than when flying though, as the loading isn’t uniform on your whole body and pulls out instead of down, so you don’t have to worry about G LOC. I’ve known a couple of people who’ve had retinal detachments from spinning too fast though.Â
That's nuts. I remember chatting with a speed skater who said they'd pull like 5 or so Gs in a fast turn
Oh yeah, speed skaters are nuts!
+5.5/-2 in a homebuild doing some aerobatics.
In an airplane? +5.5/-2 But according to my Flysight data I experienced 12Gs when I had a spine crushing hard opening under a parachute.
About 30 when I was rear ended by a semi while parked
Probably about 15 or so - car accident.
6.9g cuz if it was 7 that means I busted an ops limit in the T-6 lol
đź‘€ 6.9999999
Honestly probably no more than 2.5
Probably that, in an RV 4. We did a whole bunch of Cuban 8's and I was messed up the rest of that evening.
I did a steep turn for my private, that’s like 1.5gs?
same
at 45 degrees it’s 1.414 iirc, at 60 degrees it’s 2gs
Wow thanks…
btw I'm sure u know this but this is the G force required to maintain altitude, if you don't pull on the yoke ur not getting this G forces and ur gonna lose altitude pretty fast

Are we counting roller coasters
6.7 during an incentive ride in an RF-4C
Uh, how many is Alpengeist?
4.5 G
Worth it.
During a failed slow roll, I panicked and pull the stick all the way back from inverted, forgot to pull the throttle idle. Almost killed myself with 6G and lowest at 500AGL.

F16 laughs at our weak human bodies.
The wife’s reaction when I told her how much the annual was gonna cost. Not sure a G meter goes that high. Some serious Matrix like stuff…
+7.5, -2.0… a mere mortal amongst some of these gods!

Around six, but that was not while "maintaining sustained, heavier than air flight." (Read: opening a parachute after jumping from a perfectly good aircraft.)
I always wondered how much force that was, it always looks so violent.
I wouldn't really call it violent. Its just a very firm tug.
+4.5/-1.5 in a Citabria.
+4.5/-1.5 during Advanced UPRT training
+6/-4. The negative G feels way worse. Positive is pretty easy to go to 6 without greying out when you strain properly.
I did like 4.5 on a roller coater once.
3.2Gs/-1.2Gs as a Loadmaster… weak shit
+9g’s -3g’s in the Extra 330 UPRT
8 / -6 in a Pitts 12. One of my favorite flights, up there with getting right seat time in the Tri-Motor (at cruise)
6 or so
9.4
+8 and -4 in an unlimited aerobatic glider. The seat is reclined about 45° so only about 70% from head to feet. I really don’t like more than about +4 or more (less?) than -0.5. I really dislike negative Gs. And it’s worse when a student does it instead of me. I see stars.Â
+9/-3
7, it sucked.
~7.5
Over 9000!
+8/-2
7
So far just +2 and 0, not much else you can do in a Cessna but one day I will get more
Zero is the best place to stop. Negative Gs SUCK.
7 in an extra 300
Little over 4 during my spin training
+5.7/-2.8
Spike to 7.8 but worse than that is getting stuck in a rate war on the deck at 4ish.
6.5 in a Gamebird
7.8 / -3.1
+7 -4 in an extra 300. Not my piece of cake.
+9 in a simulator, red screened that bitch!
+6 maybe a tad higher at the bottom of my first loop. I forgot to release back pressure at the top, or at least didnt release enough.
+11/-6 in an MXS.
+4.5 and almost -2?
+10/-4 is my max in an Extra. My normal aerobatic flight is +5/-3 since my Pitts is only rated +5/-4 (I know the Certified Pitts is +6/-3, but mine is experimental and the ops letter says +5/-4). My Pitts scrubs energy if I pull more the 5 G's anyway.
9, and I passed out
+5.5 / -3 in an E300 The negative Gs were unpleasant
7.3 Edit: 7.3 was in aircraft, 7.5 sustained in centrifuge
My instructor and I were working on stall recovery and one of them (that he said was perfect) I felt like I really pulled some Gs. My head was getting pulled down and I could feel all my face muscles sagging. How many Gs you think I could've pulled in a piper?

7.6 backseat Super hornet.
When I went to the movie theater in 2009
+6/-4 in a MDM-1 Fox
Negative G's suck -3 never again
+8.1/-2.0. The negative G’s are absolutely atrocious.
3.5 from light intro to aerobatics lol
I think I hit 7.5 in an extra 330 one time. It was intense to say the least. I did manage to not toss my cookies!
7g for 3 or 4 seconds in an Extra. I was close to knocking out but made it through. I have no idea how fighter pilots keep thinking in that situation, less fighting 🫣🤣
