So, my advice would be look after yourself and always be in a good state to awake and alert when you’re getting out of a plane. At best this is irritating/unfair to the other people you’re jumping with at worst it could be fatal. Hypoxia makes you prone to making mistakes and bad decision-making – which is never a good thing in the high-risk environment of skydiving!Ĭlearly neither sleepiness or hypoxia are any good when you’re jumping as you’re not going to be performing your best in the sky. Adding other factors to that heat, not enough sleep, dehydration, lack of food, a long jumping day, post-adrenaline slump or too much alcohol the night before, and you greatly increase your risk of sleepiness and the effects of hypoxia. Not least, the lack of oxygen at altitude making you hypoxic, due to not enough oxygen in the blood and thus not enough oxygen reaching the brain, and therefore you can feel drowsy. There are various causes of feeling sleepy in the aircraft. Here are some thoughts on sleeping in the plane from my teammate, Dr Anna Hicks… That’s because there will be a small residual drowsiness influencing the next few minutes. I’m willing to bet that in the first scenario, the reaction times, keying speed, awareness, cross-referencing and general performance will be slightly less.
In the second, that same person doesn’t sleep and remains alert.
In the first, someone nods off around 8,000ft, gets woken up by their friends at 14,000 feet and does the skydive. The four examples above demonstrate why you need to be ready to skydive at a moment’s notice. You’ve literally got seconds to be ready before the green light comes on. Lastly, and one that sometimes happens, is that you’ve fallen asleep and suddenly the aircraft cabin gets super noisy and cold as the door opens.There could be an aircraft emergency… an engine could cut out, the pilot could level the airplane off and the Jump Master could very quickly tell everyone to get out! This is what everyone learns on their AFF or Static Line course.That means clipping back into the safety restraints and putting your helmet back on. The airplane may have to land due to inclement weather coming in.The plane may have leveled off as it reached the cloud-base and that means getting out below your normal altitude.So how can this help you? Even though dropzone airplanes are maintained in tip-top condition, there can be occasions when you need to be ready at a moment’s notice to get out We unconsciously learn to know how the airplane should sound during each part of the skydive. Over a period of hundreds of jumps, we naturally get to learn how the airplane sounds when it takes off, when it’s in flight and when it’s throttled back during run-in.
