I’m an aircraft electrician. There is no “earth” wire on an aircraft, only grounds. The earth vs ground argument is context driven, and also varies by region. Even the wires(braided cables) that hang off the aircraft landing gear to contact the ground when on the ground are called grounding straps/wires, not earth straps or similar.

In the home electrical stuff I’ve done I’ve mostly heard ground. The earth ground is a specific wire run from the main circuit breaker panel that’s then attached to a grounding rod.

I’m u.s. based, so I suspect the earth terminology is used either in specific industries I’m not familiar with, or different regions.

That's the angle I'm coming from. In Australia if it's green and it's in an AC application it's going to earth. It's a standard I believe in the EU as well as a couple of other areas.

Ground in AC can exist but will be floated within the device as a neutral return. It's more the wiring colour standard I was picking.

So, airplanes don't have wireless ground?
