Alternate Static Air
 
Howdy to all,
I am installing my static air system and have been wondering if others are installing a alternate static air input that I could open if I ever had a problem with ice (hope not) or contamination. A valve could be close to me that I could open that would at least give cabin air as a source..

If so, are there any valves that would be better than others

Thank you all for your valued input:-))

Alternate Static Air
 
I'm using a Clippard TV-2SP panel mounted valve with a Clippard 15070 muffler in the open port (only to prevent debris from entering the valve).

Alternate alternate static air
 
I've been contemplating doing this with a small solenoid valve and an electrical switch on the panel. The main reason is that Stein's (excellent) valve doesn't look right on my panel alongside the other (rocker) switches. One other benefit would be that I can monitor the switch and have a warning on the EFIS. The downside is that this function is electrically dependent. The other option would be to hide Stein's valve away somewhere but then it's not obvious to anyone else who flies the plane. I don't have to decide yet, so I'm procrastinating:D.

If you ever sat in a Piper PA 28 series pilot seat, you would find the alt static source sticker near your right knee with the simple 1/4 turn valve under and behind the panel lip. Simple and easy.......

Think about how you do it..... and later it can also be used as a test port.

I put one of these on mine. Changes the look and makes people leave it alone.

Not sure why??
 
Why are you even contemplating an alternate static source?
In 35 years of flying, I have never heard of anyone having a static line blockage.
Isn't one of the reasons for installing 2 static ports as per plans to build redundancy into the static system?
We don't install 2 pitots where blockage of ice or bugs is much more common
than on static ports.
Like piper and Cessnas, an alternate static port can be tucked away under the seat or behind the panel where it is still accessible from the pilot's seat.
That is a neat looking switch from Stein.

Not sure how you would monitor your static pressure.

rocketman1988 02-11-2017 04:14 PM

But...
 
With the electrical switch you could monitor switch position on the EFIS...

Then you would know where the switch was but what about the relay? And even if you monitored the switch AND the relay, you would still not know if the opening was plugged up...:D
