So I had seen this talked about on the Matronics list, and I went looking again since the panel is starting to take shape in my brain, and I found it.  In the case that both of your static ports get clogged (unlikely) you might want to be able to open up the static system inside the cockpit somehow.  This would give you an altitude and airspeed error, but it’d be close enough to get you on the ground.  Whatever, it seems like a good idea.  i’ve seen a few different ways to go about this, and the certified stuff I’ve flown usually has a way to do this.  Actually, to be honest, I can’t tell you how Cessna does it.  I’m not sure I know.  I got my license in a cherokee, and in that plane, there was an alt static valve under the panel that was a little brass valve with a lever to open it.  And they’d also tell you in pilot training that you could break the front of the VSI and that’d do it.  Well, in my plane, you could smash a bunch of LCD panels, but it’d never improve your situation :)


So anyway, I found these air valves that have a toggle switch to actuate them.  Pretty cool.  In the panel, it just looks like a normal toggle switch!  neato.  They’re made by Clippard, and I just went to Clippard.com and ordered direct from their website.  Hmmmm.  That makes it sound like it was a no-brainer.  Not quite.  I got so excited about it, that I ordered the first one I saw that looked close enough.  That was the MTV-3P.  After I ordered that one, I realized that there existed an even better one - the TV-2SP.  The latter is smaller, and has only one input, and one exit.  The bummer is that while the valve is very reasonable at about $9, they charge like 7 bucks for shipping, and 10 for handling!  I’m an idiot.  After I ordered the first one, I ordered the second one also.  All in the name of science, I suppose...  Anyway, I wondered how the hookup to the static system would be, but I thought I’d be cool, because the input to the switch valve is male 1/8 NPT, and I could probably figure it out.  Then the lightbulb...  I bought the Safeair1 pitot/static quick connect system long ago, and I busted it out this evening and rummaged through it.  Sure enough, there’s one fitting included that’s female 1/8 NPT to the little quick connect.  SWEET!!!!  So, armed with all this stuff, I went about the highly scientific blow test to see if everything worked like i thought.    Hooked the tube up to the connector, the connector to the switch, and blow.  WOOHOO!  works.  My oldest brother used to tell me that small things amuse small minds.  Must be true.  Anyway, I also tried out the bigger switch that I got, the MTV-3P, and it works right too.  I thought I’d have to plug up one of the two exit holes on that one to use it, but nope.  flip the switch up, you can blow through the tube.  Flip the switch down, and it’s sealed up tight. 


The most ridiculous thing about this whole thing is that it’ll be the only regular looking toggle switch in my panel.  I’m excited about that, because now I get to use a set of those cool looking X-plane type toggle switch protector thingys.  I bought a set.  Actually, I bought 2 sets.  I couldn’t decide between the black and the silver.  We’ll see....


Oh, and another thing - the pitot/static quick connect kit from Safeair1 is the raddest thing ever.  I’m super stoked on it.  you just push the tube in, and it’s connected.  Hopefully it won’t leak!  It almost seems too easy to be true, but apparently it works really well.  I highly recommend it.
