In Aeroplane what circuitry or method use for earthing?

Answer Posted / ramachandra pilla

earthing means not only connecting the all live bodies parts
in to the earth by means metal piece.the main theme of the
earthing is creating a return or closed path to flow
unwanted rush currents same like in the aircrafts all the
grounding wires of electrical appliances in the plane ware
connected to neg terminal of the battery hence the lekage
current will flow through this neg terminal
