I got started on the schematics for the avionics. We have hundreds of wires to connect. Instead of the traditional rats nest, we are going to design a custom PCB to terminate straight-through cables from each radio. The PCB will have a PWM section to handle cabin light dimming. We probabl will have various annunciators.
What makes us different is our decision to go 100% electronic We will have dual AHRS to compensate for no-gyros. We are comfortable that this is safe. (With our dual power systems).
