This training will become more important as new weapons systems are fielded with even higher performance capabilities. This training has allowed pilots and crews to more safely exploit the capabilities of high performance aircraft. The value of training has been well established during the decades since the 1970s and has been the subject of much research and literature, and training has contributed to extending pilots' G tolerance in both magnitude and duration. Incidents of acceleration-induced loss of consciousness have caused fatal accidents in aircraft capable of sustaining high- g for considerable periods. It is designed to prevent a g-induced Loss Of Consciousness (abbreviated G-LOC), a situation when g-forces move the blood away from the brain to the extent that consciousness is lost.
High-G training is done by aviators and astronauts who are subject to high levels of acceleration ('G').

Make sure to check out F-35 Pilot Justin "Hazard" Lee's podcast: The Professionals Playbook! During a max performance turn, without extensive training, it's probably a lot more. One of the sayings we have in the fighter community is: as soon as you put the helmet on, you lose 20 IQ points. It's one thing to make decisions sitting on the ground, it's another when you feel the world closing in as the blood is being drained from your head. I often get asked why we can't do all of our training in a simulator-G's are one of the reasons why. As a community, we've started to introduce physical therapy and dedicated stretching routines after each flight, in order to extend our careers. A few months ago, I had to get X-rays on my back to determine if I'd damaged a vertebra. In my squadron of 30 people: one pilot is unable to fly while his neck heals, another has been told by the flight doctor that he has the spine of someone in their mid-fifties (he's 39), and another is only able to fly low-G sorties. With our helmets on, over 135 pounds of force is applied to the neck at 9G's. The long term effects of high-G's can result in neck and back issues-most pilots deal with some level of general pain due to G's. It's similar to a bruise and usually dissipates within a few days. Hatch)Īfter high-G flights, my arms and legs will have what appears to be chickenpox-blood has pooled in my extremities and caused the blood vessels to rupture. The current G-suit is shown on the left, with the older version on the right. Instead of struggling for a breath, with what feels like an elephant on our chest, we can take a small sip of air and rely on the pressure-breathing to fill our lungs.
To increase endurance, we have pressure-breathing, which forces air into our lungs during high-G's. As we enter a turn, the bladders inflate, squeezing our legs and preventing blood from rushing towards our feet. We wear G-suits, which are pants with air-bladders in them. Over the years, technology has allowed us to pull more G's for longer amounts of time. In fact, it's so important that we're legally required to go into crew rest 12 hours before a flight, with an uninterrupted 8 hours to sleep. Poor sleep decreases alertness and G-awareness, which is what signals a pilot to start their G-strain. Sleep is also a contribution factor to G-tolerance. As with any athletic endeavor, it's important we eat nutritious foods and avoid high sugar "junk food." Studies have shown that with only three percent dehydration, G-tolerance time can be reduced by up to 50%. Hydration and nutrition also play an important part in the amount of G's a pilot can handle. During my time in the F-16, I gave a dozen, or so, people backseat rides-after the flight, due to exhaustion, every one of them had to be helped out of their seat. Because our flights average one to two hours, cardiovascular fitness is important as well. We spend a lot of time in the gym, working out our lower bodies, so we can push the blood against the force of gravity during high-G maneuvers.
The AGSM requires a high amount of physical conditioning.
