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.
