January 1st Powered the panel up on the bench and tested the individual circuits. Other than the secondary pump switch being upside down everything looks pretty good. The X-Air radio finally arrived in November and I am very impressed with it. To make life easier I purchased their pre wired harness and then plumbed that into my wiring scheme. It did have the slight disadvantage of having some wires which were too long but this was offset by the labour saving.
January 2nd - 7th Finished off the RPM gauge and fuel level processor systems. During the testing of my RPM/MAP gauge system which extracts information from the AV10 and displays it on two sub displays I discovered that the manifold pressure sensor that I had been supplied had the wrong pressure range. Luckily Rocky Mountain Instruments use the one I really want in their engine management system so I ordered one from them.
January 8th Powered up the turbo control unit and calibrated the power settings. The nice thing about the 914 is that the turbo control unit provides a clear indication of the power setting in relationship to the throttle lever position. I have marked these positions on the lever surround and will make a proper label later.

January 10th Fitted the fuel gauge processor into the aircraft. In order to get a good fit of the 2/16" fuel line I have used against the pressure sensor I used a short length of 4.8mm heatshrink on each of the sensor's ferrules and then fitted the fuel lines. The fuel gauge powers up correctly in the aircraft!
January 11th I wasn't too happy with the way I had created the fuel vent line exit point. I reconfigured what was originally three tubes entering a plenum into a system where the three lines are joined by Tees and then exit via a single aluminium pipe bonded into the base of the aircraft.
January 12th No building.
January 13th The replacement manifold pressure sensor arrived and, having done a small modification on the connector to make it fit the new sensor I tested it. It was pleasing to note that this new sensor thinks that the normal pressure today was 30.1" of mercury rather than the 47" of mercury that the previous sensor thought was normal atmospheric pressure.
January 14th - 17th No building. It was a glorious weekend so we decided to take advantage of the sun.
January 18th -22nd No building, working in Taranaki
January 23rd - 24th No building - had to work :(
