This made me wonder, why is max altitude a limit? Is it due to cooling (less air)? I'd be glad to know more if anyone has some insights

- Shaddox 7y agoI'm not a specialist, I just read up about it some time ago so take what I say with a grain of salt. Basically there's two issues affecting electronic chipsets at high altitude : air density and cosmic rays. The reduction of the air density can mess with the cooling system. Cosmic rays contain radioactive particles which can cause soft failures to occur in solid state electronics. EDIT : Found an interesting paper about it with more details : https://pdfs.semanticscholar.org/6046/529f05a65e182ac9323ef8eb26b2075d0e13.pdf https://pdfs.semanticscholar.org/6046/529f05a65e182ac9323ef8...
- dredmorbius 7y agoLow humidity -> static. Lower air density -> less heat transfer, so components run hotter. Air pressure may affect disk drives and other sealed / fluid-dynamic systems. Capacitors and other electronics might possibly be affected. Apparently displays and printers (liquid ink) are strongly affected. Arcing increases with elevation. https://highaltitudelife.com/electronics.htm https://highaltitudelife.com/electronics.htm https://www.eng-tips.com/viewthread.cfm?qid=24254 https://www.eng-tips.com/viewthread.cfm?qid=24254 https://en.wikipedia.org/wiki/Derating https://en.wikipedia.org/wiki/Derating
