facthunter Posted July 23, 2011 Share Posted July 23, 2011 Yes. I perforated an eardrum once and it was excruciating. Makes flying a bit harder with the distraction. Nev Link to comment Share on other sites More sharing options...
Tomo Posted July 23, 2011 Share Posted July 23, 2011 When I first moved to the USA to live at an elevation of 6300 ft I suffered from altitude sickness for a while. When I was in PNG in the Highlands we were up around 5500-6000ft, and I got altitude sickness... it's a funny thing. You feel great once you get back lower though!!

Mazda Posted July 24, 2011 Share Posted July 24, 2011 Facthunter who says "large unpressurised aircraft rarely fly above 8,000''? Many times I've been higher than that in large unpressurised aircraft. Be careful with soft drink cans though, they go strangely convex up there!

facthunter Posted July 24, 2011 Share Posted July 24, 2011 Watch out for thermos flasks. The boiling point of water drops significantly at altitude and when you remove the cap the water instantly boils. It doesn't get any hotter, but goes to the vapour state once the pressure is released. I should have added " piston engined" They don't get much more efficient at higher altitudes unless they are turbo-charged. The "liberator" would be in that category, with 4 turbo-charged P&W R-1830's. Some others had 2-stage "blowers" , mechanically driven, where you had to change gear at about 14,000 feet, to spin the blower at higher revs. example P&W R-2000, and R-2800....

turboplanner Posted July 24, 2011 Share Posted July 24, 2011 That must have been a fascinating era with so much workload you couldn't climb over it, starting with cowl flaps Link to comment Share on other sites More sharing options...
facthunter Posted July 24, 2011 Share Posted July 24, 2011 In retrospect turbo, it was pretty incredible. With a jet you just turn it and put fuel into it. I will resist hijacking the thread though. Some other time maybe.. Nev. Link to comment Share on other sites More sharing options...
turboplanner Posted July 24, 2011 Share Posted July 24, 2011 Definitely, to me that was the skill peak and the stories deserve to be told. Link to comment Share on other sites More sharing options...

Yes I've experienced the same when I have woken up in bed feeling really sick, then fell out of bed, but woke up much quicker when I reached floor level. Alan.
