I used to have a Calif as well, and I managed to install a 10 liter cylinder between/behind the seats. With the EDS, that goes a long way ;-)

Really? Which Serial # did you own?
I got the original Caproni O2 brackets and installed the longest aluminum tank that fits through the main bulkhead between the seats. I can turn on and off the tank, see the gauge and the operate the EDS. Nothing beats a roomy cockpit! ;-)

I owned S/N 38, F-CEUD (which I changed into D-6600 upon acquisition). Flew it for about 600 hrs from 1998 to 2005 in the French Alps. Absolute fantastic glider, very fond memories ;-)
The tank I installed did just fit through the main bulkhead and reached all the way back to the rear bulkhead. I installed a kind of swing at the rear bulkhead on which the bottom of the tank rested (and fixed by the horizontal part underneath the central wing section). In the main bulkhead, the top of the tank was fixed by a trap obtained from Gomolzig such that the valve protruded into the cockpit. Removal and installation could be done with the wings mounted by guiding it via the access hole above/behind the main bulkhead. And no, I never showed this to a German inspector :-D But as I said, 10 liters at 200 bars do last quite some time...

I do a reasonable amount of altitude flying here in Scotland.
I live at sea level, smoke, drink profusely (has health benefits . . some)
Get any MH EDS system, you really don't have to go as big on a bottle as
you'd think. If you have easy access to O2, go "medium" on bottle
selection, and steel for the bottle if weight is not an issue.

I routinely get 30+ hours on a very small bottle and that is based on
wearing the system at the launch point (at sea level) to counter hangovers,

then keeping it on all flight (as it is zero hassle and I'm a lazy
b'stard)
The cannula system works very well up to fL200 and allows smoking whilst
flying . . (I'm not at all sure it's rated for it, but it does work)

Oh, and budget friendly, in case the glider didn't give you a clue.

You smoke while using pure oxygen??? This must be a joke.

I guess he must synchronise the puffs from the cannula and the puffs from the cigarette.

Proves once again Darwinism isn't perfect.

Many moons ago when I was a junior hospital doctor in a chest ward the preferred oxygen mask for low concentration O2 was the "Edinburgh mask" which had a circular hole in the front with the O2 nozzle entering at its lower circumference. Some of the chest patients loved it because they could smoke through the hole. As was demonstrated to me by a marginally less junior doctor, if you held the lit cig tip directly in the O2 outlet flow it just glowed brighter. Oxygen doesn't burn, it burns.

Thanks to everybody for the helpful replies, much appreciated.

You are correct.Â* Oxygen doesn't burn.Â* But it really supports combustion!

When I was in AF flight school (early 70s, so everyone smoked), they
warned us about smoking with a mask dangling along side one's face.
Seems one fighter jock had his mask catch fire (maybe while lighting up,
maybe due to a cabin depressurization causing the O2 system to go into
pressure mode, who knows?).Â* The point was that he suffered serious
burns to his face.

Personally I never felt the need to smoke during a 2-hour flight with a
pressure demand mask and regulator.

An oxygen mask that combusts on exposure to oxygen would be a bit of a design flaw! There will have been something else that ignited before the mask. In the context of medical or general aviation oxygen use I would be far more concerned about oxygen exposure to petroleum based products (e.g. vaseline, Vicks, Chapstick on the face) than smoking
