| Subject: | Oxygen...when & why |
Dan,
My wife and I adhere to this now. We find that using oxygen gets us to the
destination much less tired and clearer headed.
I have been using ox or several years now.

I monitor an RV site and a discussion about using O2 came up. I thought this
reply was worth passing along.
Dan B. Mesa, AZ
KF-IV , 912s,
Mike and all,
It's been a while since I studied this in school but I'll give it a try:
The air we breathe is composed of oxygen, nitrogen and other gases. The
total weight of these gases equals the atmosheric pressure which of
course decreases with altitude. The one which we are concerned with is
the partial pressure of oxygen. When we take a breath at sea level the
oxygen pressure is greater than the oxygen pressure in the capillary
beds of the lung. So oxygen is pushed across the membranes of the air
sacs of the lungs into the capillary beds and under normal circumstances
the oximetry reading is about 98%. Then as altitude increases the
partial pressure of oxygen decreases, therefore it's ability to cross
the membranes decreases as well and the oximetry reading decreases.
Normal air has 21% oxygen. By breathing nearly 100% oxygen helps us to
keep our oximetry reading closer to the normal range. Your ability to
absorb oxygen is dependent on your general health, age, smoking and
other factors.
Last year my wife and I attended a seminar at Oshkosh given by a doctor
on the benefits of using oxygen. He recommends using oxygen, as I
recall, over the age of 55 at altitudes of 8000' and higher. And using
oxygen at any altitude at night to improve vision.
Hope this helps. Any questions would require some research.

| Subject: | Re: Mode C Transponder check |
when the transonder installation in my RV9 was certified, I flew to the tech's
location where he brought his box out on the ramp. After plugging everthing in
and getting his readings he charged me $25. Seemed a bargain.

Hi All,
Last night a fellow I met at the airport gave me a call. He's an avionics tech
and is willing to bring his equipment out to my hanger and check my mode C transponder.
I believe he's also going to check over the regular altimeter etc.
He says he'll beat the price an FBO would charge. What's a fair fee for having
this work done?
Thanks,
Ken Davy

... talking of which - how about you, guys on the other side of the big
pond, are you getting ready for mode S? Here, in Europe, it should be
compulsory for GA from April 08. But as far as I know, nobody is in a
hurry to trade their old mode C. I even flew last week across Europe
without transponder at all. Okay, I had to stay under 1,000 ft most of
the time and since I needed a flight plan to cross borders, I had to
report my position now and then. But it's still possible.
Cheers,

I follow the same rules. Although I'm not yet 55, I sure feel that way sometimes.

Was using a portable Icom intercom and radio but went to a panel mount radio
intercom combo for better radio performance. The new Xcom worked great all
the way to osh and back. http://www.mcp.com.au/xcom760/ is the site for
the radio
