Post it from the chamber > 25K. It's got wifi, right?

gotta admit, I'm a bit jealous. Have to look to see if Shaw,McIntyre (sp), CHS, or Beaufort has something like this.

then there's Armstong's line at ~62K

Thanks UAL- I am surprised they use an altitude as low as 25k as a test or teaching altitude, I guess it shows that you might be functional for a little while at that altitude if not for very long.

You can post in this thread or start a new one if you feel it will get more attention. I decided to just revive an older thread to announce the class. There are already about a half a dozen Hypoxia related threads.

Cub:

Apparently, one of the reasons for 25k is the slower onset allows (in theory) one to learn to recognize their own symptoms.

The other reason: as a new USAF student (30 years ago, next month!), we did a rapid-decompression ascent to 35k, if I remember right. But they stopped the 35k profile a few years later. A student either got hurt, or died from some reason....LOC, evolved gas; I never got the full story.

Yeah, DCS and embolism become serious risks with more change in pressure, and a faster rate of change only makes it worse.

To avoid those issues, military jumpers pre-breath O2 well in advance of de-pressurizing...going straight to 35K on air would be a risk I wouldn't care to take just for some training value. Your joints might remind you for the rest of your life...

If they were in a Lear 35, which I don't think they were, it was probably a 25, the pressurization system is pretty crude compared to the 35. There were several warnings that would have to fail for that to happen.

I'll take this opportunity to once again BUMP the program called 'Portable Reduced Oxygen Training Enclosure (PROTE)'.

It seems to take a long time to get the word out as I mentioned in this thread back in 2009 with my own previous experiences with the ROBD, but it was brought to my attention again in last month's copy of the 'FAA Safety' magazine. The article gives contact information for requesting the PORTE make an appearance at your location. Contact Rogers V. Shaw at 405-954-4837

In the same article, the Night IMaging Training Environment (NITE) Lab is mentioned. For those in the military - this seems to be the standard NVG Lab that we all had to attend on a periodic basis. POC for scheduling is J.R. Brown at 405-954-4837.
