wrote: In accounts of the crash of the Cypriot airliner in Greece, all I've read say that loss of cabin pressure could not, by itself, incapacitate the pilot. Yet, I was once told by an ATP that at 40k feet (admittedly this plane was at 35k) O2 supply by itself will not suffice to keep you conscious and that the drop down masks only give a false sense of security. He said that the ambient pressure is so low that even 100% O2 does not provide enough to keep you conscious without a pressure breathing mask. I personally know glider pilots here in New Zealand who have flown to betweeen 35,000 and 37,000 ft with only an ordinary oxygen mask, not a pressure system. It's OK at 34,000 ft and above 38,000 ft. And all other altitudes, partialy. You were asleep or missed this class, right? moo |
