23rd February 2009 - Panel Wired
I spent yesterday installing the instruments and avionics into the new panel. The concept behind the panel was to use modern avionics but in a panel sympathetic to the age of the aircraft's design. The left side of the panel and avionics are in their final locations, the right side will still be subject to change once a choice of engine has been made. The wiring is largely as per the Aeroelectric Connection Z11 layout. There are three main power buses, an unswitched battery bus, the main power bus, and an endurance bus. Individual fuses for all the electrical components (except those required to be pullable) are mounted on a power distribution tray mounted behind the switches and fuses on the right side of the panel. From left to right and bottom to top the various switches, sockets and gauges are as follows.
