Does anyone have a source or suggestion for the alternate air valve  

like the "real" planes have?

My Real RV10 has an alternate air source, I used the kit for the static

system from Safeair, and included the alternate option. But I do not

know if the RV10 is real enough for you?

A lot of "unreal" type certificated aircraft are certified for IFR

without an alternate static source. Both TC aircraft I have owned fit

that description.

My Cherokee has the same valve for an alternate static source as the fuel quick drain valves.  I don't recall their name, but I can look it up when I get home.  I paid like $75 dollars to get it from Wentworth, so I was sure to installed the OEM part, but was disappointed when I saw what the valve actually was and could have bought the same valve (although not with the appropriate Piper p/n#) from my FBO for about $10.



In looking at the Safeair alternate, while it appears to be quite easy to remove the plug, how easy is it to blindly replace the plug for testing?



The valve on my Cherokee can open and close blindy with one finger.  The valve is just under the dash by my knee.

I put a similar 3 port valve in my panel. It is simple, accessible, and easy to use.

To bad they need a $75.00 min order. Looks like a good solutin to the 

alternate air problem.

I was intrigued as well, so a little searching and I found this:



http://www.clippard.com/store/display_details.asp?sku=MTV-2P



1/8" NPT on the back. That should make a really nice alternate air  

source selector. Price: less than 12 bucks.

Here is the clippard catalog

<http://www.clippard.com/downloads/general/PDF_Documents/2006%20Catalog/Catalog%20by%20Section/2-Way%20Control%20Valves.pdf>



I was thinking the TV-2SP

$9.03 or $9.85 with epdm seals.  But the catch $5 handling and $10 shipping.

$25 makes a pretty slick alternate air set up.

Michael, I too am interested in acquiring one of these valves and would

be prepared to send you the funds for purchase of an additional valve

with your order, inclusive of costs for shipping downunder.

Mine actually came with my kit (no, I'm not an RV-10 builder), and I'm sure that you can get one cheaper from one of the suppliers listed above. Mine has 2 threaded fittings (static line in and static line out), and an unthreaded opening. In the normal position pressure from the static port just passes through the valve. In the alternate position, the line out is opened to cabin pressure. You could probably also use a valve with a single threaded fitting and T it into the static line.
