I would greatly appreciate critiques of my preliminary architecture for the power distribution piece of my project. Don't be shy.
Mission is:
Day VFR, rare night VFR
Cross country, mostly
Failure scenarios:
1. Main alternator fails - Aux alt covers most everything so I can get to tools and fix it in case I am over nowhereland when failure occurs.
2. Main contactor fails - Pmags keep ship aloft, Dynon HDX1100's have backup batteries and power flight essentials (air speed, horizon, vertical speed, engine health, navigation) but not ADS-B, XPNDR, ELT, Lights, pitot heat, starter (so, landing somewhere with parts and tools would be nice.)
Even if both alternators and main contactor go south, the hot bus and self-powered Pmags keep the ship aloft. Fuel is the only limit, I think.
