G-Force, Jerk, and Passing Out In A Centrifuge

Tom Scott

    Thanks to the Starrship team for arranging this! I'm also over on their channel, flying with the Blades: seprom.info/clone/video/zLqOZZNpl3-k2qM.html • At the Royal Air Force training centrifuge in Farnbrough, pilots learn how to avoid G-LOC: g-induced loss of consciousness. Let's talk about g-force, about jerk, and about how to keep circulation flowing to your brain.
    FAQs:
    * Isn't 3.6g a really low g-tolerance? *
    Yep. Turns out I would not qualify to be a fighter pilot. The average range for g-tolerance is 4-6; no-one was expecting me to pass out. The centrifuge team do not deliberately try to G-LOC people! To be fair, though, I'd done a few earlier runs with only minor effects.
    * What g was the RAF person at the start pulling? *
    That's Marcus, from the Starrship team, and he was successfully pulling 6.5g with the help of g-trousers: they plug into a compressed air source in the plane (and in the centrifuge) and act as a lower-body tourniquet to keep the blood up top. They are very effective.
    * Why did you shake and shudder when regaining consciousness? *
    Those are called "myoclonic convulsions", which is a fancy medical term for "muscle jerks", and they're a common side effect of recovering from G-LOC.
    * What did it feel like? *
    I'll answer this in more detail in a video over on the Matt and Tom channel soon, but in short: I don't remember it. I was doing the breathing maneuver, then everything was wobbly, then we were stopped!
    * Is this a sponsored video? *
    No: the RAF and Starrship had no editorial control over this, and no money changed hands. Obviously, though, they gave me a spin in the centrifuge, and I'm collaborating with them over on their channel too!

      If you have questions (what did it feel like? why did you convulse? isn't 3.6g a really low tolerance?) pull down the description, I've answered a few there! And if you see someone ask a question that's in the description, please point them there.

        @Tankie Guy I think everybody has experienced 5gs of forces, that's how much a roler coaster is...

    2. Michael Barnes

      There’s more g force on the smiler and I went on that when I was 12 grow up Tom 😂😭😂🤡

    3. Ervinas E

      You know what is a real challenge? Real challenge is not to laugh at the comments at 1am.

      DOESN'T THE GUY CONTROLLING THE THING EVER GET DIZZY ?

    5. Saadi Arsalan

      bro that was so close!

    6. Scott FitzPatrick

      If g force pushes the blood towards the legs and a s result causes unconsciousness, why not reposition the pilot so it pushes blood towards the head.

    7. Sputnik

      romain gorsjean had a crash with F1 car and hit the wall with 53G kimi raikkonen hit the wall with 43G they both got out of the car with minor injuries.

    8. Vavilon

      Какой британский акцент.!почему я его слышу.?

    9. Wuppy Yadom

      They forget to put the special suit to retain the gforce, rip to this guy

    10. PenileAugmentation

      Could orienting a pilot differently (as opposed to a sitting position) work to make G-LOC harder to get to? Upside down seems like a great recipe for a stroke or something, but maybe laying down makes more sense for someone who needs to endure high Gs? Keeping the head close to the same level as the rest of the body. Probably not worth it in most situations I suspect.

    11. Samin Khan

      SWAT KATS!

    12. Samuel Hopely

      Tom passed out at a little over 3.5 G, which may seem silly or wimpy. Let me assure you that stronger and fitter men have withstood less. Vertical G force is absolutely soul crushing. Even F-16 pilots pulling 9G sit in reclining chairs that mean they only experience about 6-7 G along the vertical axis. If you're ever lucky enough to ride in a high performance aircraft, just remember to go into the experience with humility, because you'll certainly come out of it with some.

      The instructor in the middle goes like: You spin me right round baby right round, like a record baby right round, round round.... 🎶

    17. Elbisrever

      I think Grossjean holds the new record of peak G-force now.

      this is way less harrowing with the sound on, i should have watched this before the park bench episode!

      It could be worse than that if you ascend the aircraft upside down

      I just like to think how much of a flex this is. - I could lift 35 pounds yesterday. - That's cool. I died yesterday.

    33. A single Banana

      Imagine bacteria have to withstand 8000 g for 15 minutes in a typical centrifuge. RIP.

      only 3,5 G? **vegeta laugh**

    38. Aaron Dunn

      ...you call that AGSM? Yikes...warm-up G loads should be at 5 G. Peak centrifuge forces to practice proper AGSM lies between 7.5-9.0 G. (KBR Centrifuge -- San Antonio, TX)

    39. TyroZenavia Gaming

      Sriwijaya planes hit the sea at 600+ km/h about 10G force. Maybe passenger lost consciousness before that happen. Condolences to the family.

    49. James Lonergan

      I'm no math genius, but it seems to me that some kind of opposite force to the Gs, like lateral thrust (jet propulsion from the sides of the aircraft)

      The brief moment of euphoria that you experience when you're just about to pass out from the g force. No amount of dope can get you there.

      F1 drivers experience around 3-5 Gs average, peaks are around 7.

    59. purpl3grape studios

      Random thought: would cocaine help or be of detriment in withstanding higher g forces than without?

    89. Shawn Elliott

      I have a mild case of postural orthostatic hypotension, which means my body doesn't automatically adjust my blood pressure and blood flow correctly when I'm upright. I wonder if I would do worse at this test than Tom did, or better due to the practice I have keeping myself from feeling lightheaded just standing around.

    90. le derp

      so... what jerk+snap range is ideal for humans? what range is sustainable? have we tried putting bugs in centrifuges?

    91. Hello 2021

      is there any magic tricks that the instructor used to not feel dizzy when spinning?

    92. Mike Cochrane

      A moment of respect for F1 drivers who for 2h every race experience up to 3g corner and 5g braking forces several times a lap. And stay focused enough to not just drive a car but RACE it. And in terms of jerk forces: lots of research in racing too. Drivers hitting barriers and experiencing 50+g in accidents walk away. FIA have g meters in helmets and gloves that monitor drivers and deploy the medical car if it exceeds a certain threshold even if the driver climbs out apparently unharmed.
