![]() Todd - Yes it can, in fact we can't tolerate very much of that, only about -3 Gs, its called negative G. It helps get that blood up to your brain.Ĭhris - So that's the blood going away from the brain, but what about if you do the manoeuvre the other way, does this force blood into your brain, and can that be dangerous? It's squeezes the leg as soon as you hit about 2 Gs. Some cover the whole leg, some only cover parts of the leg. A typical G-suit has an abdominal bladder and bladders in the legs. Medical doctors will be familiar with the mass suit, which was developed to prevent shock this was developed from the G-suit, used in the military. The main thing we do is we train them in how to perform what's called an anti-G straining manoeuvre.Ĭhris - So when you say G Suit, this suit puts pressure on the body, squeezing say, on the legs and this stops blood from pooling in the legs. What we do is we put them on there and we train them how to use the equipment, we put them in G suits - which only gives you about a 1 G increase or so in G tolerance. We do that by providing training on a human centrifuge, and there are two the air force uses for that. ![]() Unfortunately, in the military environment sometimes you have to pull 9 Gs, so we have to come up with ways to counter that. We have a lot of mechanisms that we have to train the pilots to do, fighter pilots specifically, and also technology that we use to keep the blood flowing to the brain.Ĭhris - So are you saying that you tell people not to do movements that would subject them to 9 Gs, because to put that in perspective if your head is feeling 9 Gs the weight of your head is effectively nine times bigger than normal, isn't it? ![]() Todd - In real terms it means you have to be able to get that blood, keep that blood, up to your brain, so you don't lose consciousness eventually if you don't have some sort of way of keeping the blood from pooling down. That's what we call 9 positive Gs or at the vector going from the head down to the feet.Ĭhris - In real terms, what does that mean, Todd? Fighter aircraft for example, pull up to upwards of 9 Gs in the aircraft. But what sorts of forces, G - forces will people who are flying very fat planes actually be experiencing?
