Apr 20, 2007     Piping the Pitot and Static System - (14 hours)       Category: C13 Nose+Gea
For the pitot, I found a small air compressor blower nozzle on McMaster-Carr that had a threaded fitting on one end. A threaded bushing in the nose provides the connection, giving me a removable pitot. An elbow joint completes the picture by connecting to the aluminum tubing that runs up to the instrument panel.

For the static port I found some small machined aluminum static ports that seem like they'll do the job. They (one per side) get installed in recessed holes just under the outside skin and plumbed the same way.

PK note, November 2021.
1) The removable pitot is an M10 thread, with a barbed front. 6mm Barb x M10-1 Male; Total Length: 1.22"; Hex Width: 7/16ths. I have a pitot length of 7/8th inch, with the lip barely forward of the landing light lens. In flight testing I'll determine any pitot-static error.
2) As described elsewhere I have pitot heat from a thermal tape wrapped around the aluminum tube. The temperature test went well. I still need to test for a self-draining ability in the pitot system.
2) Pitot static plumbing went missing from the project as delivered, and I assume they were retained by Craig W. I bought a full pitot-static kit from ACS ("Avery EFIS System Plumbing Kit" at $132) with lots of hose in 3 colors and way too many fittings.
