Oxygen is REQUIRED at 14k cabin altitude for pilots. It is recommended well below that, and for good reason. Hypoxia is a deadly killer that can sneak up well below 12k. I have personally seen it impact crews in military aircraft between 10-13k. Throw in medical factors, excitement, fatigue, and bad things can happen in the legal-without-oxygen realm.
Each pilot should evaluate their own need for oxygen above 8k and make the choice their best judgment dictates. If you needed it and did not have it, your odds of living to remember that mistake are a lot less than if you had it, used it, and did not need it. Of course, flying above 14k without oxygen is in violation of FARs and less than intelligent. Fly safe. iMs, Zip ---------------------- Agreed. The point was that O2 is not a requirement for less than 30 minutes at 12,500', and hypoxia at that altitude is very much subject to physical condition and acclimation, although longer periods do require O2. The photo showing a significantly higher altitude said nothing about the conditions. But I would strongly recommend against doing something like that without O2. As you say, that would be illegal, as well as potentially deadly. -Jeff Scott _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
