An excellent, recent thread debated the merits of various systems and functions on the two or three different buses that more advanced airplanes have. I am not building an advanced IFR ship. I am building a very simple, VFR RV4 and considering putting everything on one bus. My airplane is all manual, carb/mag. I have spent many hours reading Aeroelectric Bob's book and system design Z-11.
My electrical needs are:
1) Comm
2) Transponder
3) Enigma (all in one glass, includes GPS)
4) Intercom
5) Whalen combo strobe/nav lights
6) Landing light
7) Taxi light
8) Fuel boost pump
9) Van's alternator warning light
10) Power receptacle for handheld comm
The Enigma unit will have a dedicated backup battery that is completely isolated from the main system. I have only seven bat switches total, not using keyed mag switch.
My airplane is simple for my personal mission profile, not budgetary. I have all the parts to put in two small fuse blocks and have roughed in (cleco) a small tray to mount them on. The more I put my mind on this, the more I think my system only needs one bus.
Any comments appreciated. I am trying to learn and be safe.
Sincerely,
