Unless you are moderately active in excercise and live in the rockies at 5000
feet or higher, or are a particularly unusual person, you WILL be impaired at 10k for any time longer than a few minutes. Hypoxia is insideous.

But there's impaired and IMPAIRED.

I've lived at sea level pretty much all my life - where I live now is
about 90ft MSL, where I last lived was 25ft MSL.

However, I can happily go skiing all day long in Utah, doing vigorous
exercise between 9000 and 12000 ft all day long. I am not unusual (well,
I might be weird but physically I'm not unusual).

My first post on your group.
I've read this entire thread and am suprised that no one has mentioned
using
an O2 system from a home healthcare type source.
It's the same 02, the same bottles. the same delivery method, just
maybe a
whole lot cheaper than buying something that says "airplane" on it.
I've been quoted about $200 for a 6# tank and regulator, with cannulas.
The
Regualtor is metered by volume per minute. ie 2 liters per minute.
Would this work, why? why not?
About me,
1972 Piper Arrow II only capable of flights to around 12,000 MSL ( for
all
intents and purposes)
Dallas, TX.
Would like to have it cause I don't want to die.

IN ground school I was taught that medical O2 has water in it which can
freeze in the lines at high altitudes and low pressures. I've never
used O2 so have no firsthand experience.

There may be a difference in the water specification between medical and
aviator's oxygen, but there is no practical difference. It all comes from the
same oxygen plant. There's an article on the subject at avweb.

I've never tried it, but I've been told that medical oxygen supply places want
to see your prescription, or no sale.

I have had the same experience, although my ability to tolerate high
altitude exercise has declined with age (I'm 61).
I have also flown frequently between 9500 and 12500 with no apparent
ill effects. However, my wife complains of
headaches if I take her above 10,000 or so.

It works just fine. I have a medical cylinder and the local medical gas supply house happily refills it. The
regulator is in liter/min. I asked one of the Oxygen system vendors at Oshkosh about that, and he said a
good rule of thumb is one liter/minute per person. I also bought a pulse oximeter, so that eliminates the
guess work.

Pilots in WWI routinely flew patrols at altitudes up to 20,000' without oxygen.
Basically, being physically able to perform at 6,000 meters was part of the
criteria for being an airman. If you couldn't hack it, you washed out (or died).

Drink is the curse of the land. It makes you quarrel with your neighbor.
It makes you shoot at your landlord. And it makes you miss him.

Thanks for all the great responses!

Another question that hit me (without getting into the whole aviation 02
vs
medical 02 vs welding 02 debate)

What is the average cost for your refills with aviation 02?

By the way, all the vendors will top off your bottles for free at Oshkosh
(and probably the other major shows). Handy thing to remember.

check your 5 yr inspection date..

I bought a small Sky-Ox bottle about five years ago. I use it over the
Rockies. I'm usually solo and it goes about 2.5 hours at 15,500 feet,
which is more than enough to get me home.

I have a factory installed 2000 lb system in my TR-182.

All oxygen systems are 2000 psi. The capacity varies.

This accident was featured in FLYING magazine's aftermath column a few
years ago.

Interestingly, our EAA chapter hosted the one of the NTSB guys who covered
this accident. His telling of the tale was even more interesting than the
NTSB official report. After they went through the records of the FBO which
sold the "oxygen" to the accident aircraft, they had to track down all of
the a/c which had recently purchased 02 at the same FBO to warn them of the
02 problem.
