Group Poll :Oxygen

Same system, diff. plane. Same use alts and duration.

You didn't mention a oximeter but I thinks it's a must.

Thx, {|;-)

I have a factory installed 2000 lb system in my TR-182. I use it with
cannulas equipped with a flow meter. With this set up I generally get
about 20-30 hours from an O2 fillup. I use O2 from about 11K up, 8 K
at night. Above FL180 I have to switch to a mask, as per the FARs, so
I generally don't bother going up there.

I own an Aerox (two places regulator) with a "M" tank
(22 cu feet at 2216 psi) which I use mostly with an
'oxysave' canula;

The reviews I read were saying the aerox regulator
was most reliable -- note that the regulator is what
makes the difference really between brands, tanks
and canula/masks being pretty much the same -- and
I picked the "M" tank because... well, dunno :-)
looked like the best comprise between size and capacity;

I use it if I plan on spending some time above 5000 at
night and 10000 during the day and during long cross
country (much less fatigue at the end);

How old is your son?

I have a 5 year old and I'm wondering if he'll tolerate the cannula.

I fly a Grumman Traveler with a handful of mods, including a Powerflow
exhaust system. I bought an Aerox system after the Powerflow
installation and use it any time I'm flying above 12,500, which is
more frequent than you might imagine.

A few years back I remember telling someone I was flying from Dallas
to L.A. for a few days. They asked what "pass" I was flying through.
I thought it was a weird question. I said I'd cross the mountains at
16,500 and fly back at 15,500, what pass did I need?

With the conserving cannula on me and my son I did exactly that,
although I didn't watch my altitude for a while and accidentally got
up to 16,800 at one point. This was in the middle of the summer, by
the way, so DA was probably a bit higher. Gotta love the high
compression stc, landing gear cleanup, Sensenic prop STC and that
Powerflow!

I have an aluminum E cylinder, 22 or 24 cu ft., can't recall. It is a
two-person systemm and I get 15 hours of dual use out of that on
average when fully charged, but I plan on about 10-12 to allow for
imprecise metering.

Unless you have a plane that can really haul more than two people and
still make it up over 11,000 I would say save money and get a two
person system. I would also not get anything smaller than 22 cu ft.
Main reason is that it allows you to fill it up cheaply at home or at
the cheapest place on your route, rather than have a system that is
costing $50-$100 to fill every 5-7 hours along your route.

Also, strap on the cannula before takeoff and get EVERYTHING
configured beforehand so all you have to do is start the flow of
oxygen before 11-12k.

I own a precise flight (nelson) bottle with the scuba-type
(conservers) regulators for the me and Margy and a couple
of the cheaper ball-in-tube flow regulators in the rare
event of passengers.

Comes with a nice bag, unfortunately the strapping they give
you won't mount to the Navion seats (needs the type of seat where
you can fish the strap between the seat bottom and seat back).

The regulators have the nice feature that you can turn up the
oxygen if you decide you need more than the default setting
(set by altitude). The conservers do a good job on extending
the bottle times. Both of these are an improvement over the
Mountain Home system we also looked at which doesn't do as good
of a job on conserving, is essentially a "black box" that you
can't adjust, and requires a battery to boot.


Size/capacity?

22 cubic foot

Typical altitude flown when in use?

Anything approaching 10K or more. Lower at night.

Comments please.

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?

I really like the idea of Precise Flights pulse system, but I'd like to
compare the cost of 02 saved vs the cost of the adjustible pulse controller
vs the claimed increase in comfort over the regular non-pulse systems.

Thanks again, lots of great answers!

Aviation 02, $25

The MH is very deluxe. You feel great on about 1/4 the oxygen
that would usually be required.

Probably not for the casual user tho... It would take a lot of fills
to justify the price.

It's not just about the direct economics of the situation.

Using less oxygen means being able to be more selective about where one
fills up the tank. I've found that traveling across the country, oxygen
fill-ups vary widely in price. I've seen as low as $15, and as high as $50
or more. It would be nice to be able to tell the folks selling for $50 to
take a hike, because your tank will last you another three legs (or more!).

And of course, there's the sheer convenience of not having to fill up as
often.

Now, granted...that's not a computable benefit. One has to decide for
themself what that convenience is worth. But an airplane owner has often
already decided they are willing to spend extra for convenience; a LOT
extra. The extra expense for the fancy oxygen system often pales in
comparison.

Besides, a 1/4 the flow and $50 fillups, it won't actually take that long to
pay for a Mountain High system.

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.
