Angier,
Fact: The pulse demand controller only provides O2 when you inhale -
thus uses much less O2 than a continuous flow system. O2 outlets can be
panel mounted.
Experience: I use an 8.7 cu ft aluminum tank mounted behind the pilot seat
and the pulse demand system to a comfortable cannula. While the
controller is battery powered, I also provide it with ship's power. The tank
size matches the aircraft size but provides hours of O2. Like the
military, if the planned flight is above 10,000 MSL, the tank is turned on
before take off and the controller is set to deliver O2 above 5,000
MSL. Trips to the Factory Lancair fly-ins in Oregon always required
O2 since flights over the mountains and typical September forest fire
smoke had some trip legs at or above 16,000 MSL.
Attempt at humor: I provide a dummy cannula to the
passenger. Lacking the screams of terror from a sleeping
co-pilot makes for a peaceful flight...

I for
one, would like to see LML return to its roots because in my experience, it's
been adrift for a while. In other words, discussion of building techniques and
problem solving and best building practices generally as they apply to our
Lancairs. As well as interspersed with discussion of
how to safely and
responsibly fly what a lot of us put together in our basements over many
years. How about the topic of approach to stalls and spin avoidance. Gee, we
haven't heard much on this subject in quite a while. :-) How about portable
oxygen solutions, is there a clear winner out there? I plan to test the upper
end of the altitude envelope in my 360 this year so I need to know.
And as
for pre purchase advise for a 235/320/360, do your homework and go get a ride
or 2 or 3 or more. Is there anyone left out there who does not know that the
235 gross weight was increased to 1500 lbs over 14yrs ago?
Oh, and here's a
suggestion that may send a few people running for the hills, opinions may be
interesting but really ought to be backed up by
fact.
Cheers,
