Pilots are equipped with two sick bags, which go into pockets on the front of specially designed trousers that inflate to keep blood from pooling in the legs. “No pre-programmed runs – but we can do those for trials where we need consistency. “Everything’s generally flown by the pilot,” says Bolsover. The interior of the gondola can be fitted with three different cockpits – a Hawk T2, a Typhoon, and an F-35 Lightning – so pilots can get used to the specific control layout they’ll be using in the air. The Cranwell facility cost £44 million (about $57 million, AU$81 million), and features a gondola attached to a seven-meter arm, driven by 20-tonne gearbox and drive capable of delivering over 4,000 horsepower. The new centrifuge can reach 8G per second – the same onset rate pilots will experience in a Typhoon fighter jet. Current NATO regulations state that simulators should have an onset rate of 3G per second. The old device has an onset rate of 1G per second, meaning it takes nine seconds to get up to 9G. The new simulator can also reach high G-forces much more quickly than its predecessor. You then need the distraction of flying an aeroplane, because you’ve got to make that G-strain automatic, and that’s what this training’s for.” You can teach anybody to G-strain if they’re just sat there doing nothing else. “Here, the whole idea is you will fly the aeroplane type while you’re doing the G. “In the old Farnborough simulation, you just sat there in a seat and you’d have nothing to do, because you’d just be sat there being tossed around,” Bolsover said. It worked well, but was a much simpler device and doesn’t meet the latest standards for training pilots to fly modern fast jets. He explains that until now, the RAF has carried out G-force training using a centrifuge in Farnborough that first came into service in 1955.

Repeat.Ĭontinue the technique until you return to a low pressure level.The centrifuge has an onset rate of 8G per second. This step should take no more than one second - just enough time to let blood flow into your heart and chest, but not enough to allow the blood to leave your brain. Next, inhale quickly in preparation for the next repetition. Strongly exhale and finish the word “hook,” drawing out the “K” sound. Exhale, Finish the Word, "Hook," and Inhale. About three-quarters of the way through the word, before hitting the “K” sound, close your glottis and hold for 2.5–3 seconds. Start the Hook Maneuverīreathe in, and begin to say the word “hook.” You should feel your glottis, the opening between your vocal cords, at the back of your throat. Tensing your muscles will help keep the blood pumping in your heart and brain. G-forces push down, pooling your blood in your abdomen and legs. Pay attention to pressure levels - when you feel the downward force of the Gs, get ready to start your AGSM. Below are the steps to performing the Hook Maneuver: Anticipate the G Now, you may never encounter as many Gs as Burgess has, but understanding how to combat the forces when the time comes can be the difference between enjoying the sensation and waking up from a less-than-desirable state. The resulting report by the Naval Air Development Center explains that the Hook Maneuver “simply emphasizes the proper mechanics for physiologic enhancement of tolerance,” in a way that is “easily understood, rapidly mastered and easily remembered.” How to Perform the Hook Maneuver The maneuver was unclassified in 1990 in a response to civilian desire to know how these pilots keep their cool in the cockpit. The Hook Maneuver is a Navy flexing technique taught to fighter pilots in order to help them keep blood flow to the brain during moments of intense g’s.
