Matt,
The people who do pneumatics installations use a certain size tubing and with it
comes plastic fittings that allow you to push the tubing into the fitting. When
you do it ,the fitting, snaps into place and locks the two together. They
also make t's and even a panel mount pneumatic toggle switch. HTH

Matt:
Checkout the SafeAir alternate static port. Toward the bottom of this page.
http://www.safeair1.com/PS_1.htm
You should be able to make something like it if you do not wish to purchase
theirs.

Does anyone have any suggestions on something I could just cut the tube and
stick in line with a little thumb screw to switch between the fuselage or
cabin source?

What a great idea, Linn! Thanks. Here's what I did tonight including a
couple of pictures...
I added a small "T" Nylon fitting in the 1/4" tube for static air just in
front of the instrument panel under the left cockpit rail. I cut a short
piece of 1/4" tubing and filled it with black RTV and then put a piece of
heat shrink tubing over it to form a handle. The whole thing fits nicely
under the cockpit rail and from the pilot's position is just barely visible,
yet can be accessed easy. In the event that icing conditions occur, the
fitting can be unscrewed and the plug removed for cabin venting.

| Subject: | TSO'd Instrumentation For IFR? |
Dear Listers,
I'm working with the local FSDO this week and had my airframe inspection on Monday
will get my sign-off this Friday if all goes well. Looking over the requirements
for IFR, it appears that I've got everything I need as far as equipment
is concerned. I have a Garmin SL-30 for Com/Nav and a Garmin GTX-327 for Mode
C transponder. All of the other equipment and functionality is provided by
the GRT Horizon HX sytems including the encoder, attitude, airspeed, altitude,
compass, etc, etc. I do not have any steam gauges or other flight instruments
other than what is provided by GRT through an HX installation.
My question is can my RV-8 be approved for IFR flight with this compliment of GRT
HX specific instrumentation? Or, would I need to have a TSO'd encoder and/or
other TSO'd pieces such as rate-of-turn, slip, sensitive altimeter, artificial
horizon, direction gyro, etc?

The FAA does not approve it=2C you do.
Your Operating Limitations should have this Operating Limitation listed "Af
ter completion of phase I flight testing=2C unless appropriately equipped
for night and/or instrument flight in accordance with =A7 91.205=2C this ai
rcraft
is to be operated under VFR=2C day only."
