... and then there's they guy from the thread a month or two ago that said
that since he was barely affected (aside from a bit of shortness of breath) when doing
manual labor in an unpressurized plane climbing to 25,000 ft that all the hype about
being "noticably affected" below 15,000 was bull****.

Again I call bull****.

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.

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.

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.

Do you own/rent/borrow a portable oxygen system?
Which brand?
Likes/dislikes regarding the particular brand?
System features?
Size/capacity?
Typical altitude flown when in use?
Comments please.

I considered all my options with respect to oxygen and ended up with the
Precise Flight System. I ordered the 'M' cylinder one with two of the
demand valves and two regular devices. Four face masks and all the other
goodies, of course. Last Thursday I went from Tucson (KAVQ) to Portland,
OR (KPDX). Mostly, we were at 14,000 ft, IFR. I returned home on Sunday,
mostly at 15,000 ft. The trip was 7.1 hours up (with weather deviations
and a precautionary landing for weather) and 5.9 hours back. 13 hours
total flying time. Probably 12 of those hours on oxygen. Two people. The
FBO didn't completely fill up the tank (1700 psi) before I left, but I
didn't run out of oxygen. There isn't much left in the tank but it
appears the demand valves allow more than 24 person hours on a tank. I
also bought into a transfilling system with another guy at the airport
so filling the bottle won't be expensive.

I take it you can tell beforehand from the pressure gauge? Why wouldn't
they fill it completely?

I have frequently run into FBOs that can't supply a full 2000 psi of
pressure. Why this is, I don't know (I mean, I understand the mechanics of
it, but why they maintain their oxygen supply at such a low state, I can't
say). But it's actually unusual for me to get my tank actually filled with
a "fill-up".

By the way, the range of prices I've seen only has a passing relation to the
amount of oxygen I get. Of course, I don't pay full price if I don't get a
full tank, but sometimes I can get a full tank (starting from nearly empty)
for a low price.

They were getting ready to close and would have had to retrieve a fresh
tank. 1700 was fine this time.

Because they either don't have a cascade or don't know how to use it
properly. They probably stopped at 1700 because that was all that was
left in their single bottle.

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?
