I understand best practice is to ground all the avionics to a common point on the firewall to avoid ground loops.
My avionics vendor provided ground wires that only reach the sub-panel, so I need to put my forest of tabs there. I guess I have three options:
1) Insulate the forest of tabs, and run a cable to a common grounding point on the firewall.
2) Bond the forest of tabs on the sub panel, and let the current flow through the airframe.
3) Bond the forest of tabs at the sub panel AND run a cable to the common ground on the firewall.
Problems with any of these options? Which is best?
