(Matt Dralle) ________________________________ Message 1 _____________________________________ Time: 01:51:29 PM PST US From: Matt Dralle Subject: RV7-List: Check Valve For Static System Cabin Venting... Dear Listers, Looking at the requirements for IFR certification of the RV-8, it looks like the only thing I don't have is an "alternate static source". This seems like it would be as simple as adding a "T" valve in the 1/4 neoprem static air tube that goes along under the left hand canopy rail. 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? I'm assuming this will meet the requirement? Thanks! PS - Attached are a couple of pictures from Taxi-testing and Magnetometer calibration this weekend. Cool?

I talked though the each of the things as I was checking them in an HD video I edited of the session. Thought some might find it interesting... http://www.youtube.com/MattsRV8?v=-byMWhyTwjA ..

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.
