I'm having a hard time understanding Chassis Grounding. From my understanding, the frame of a plane is used for that and all of it can return to the batterie.
Given my understanding, it remains a closed circuit that always has the same number of coulomb (Batteries and Chassis included).
Let's pretend a lightning hit the plane now. Wouldn't that add coulomb to the closed circuit? If so, is there a limit of coulomb we can add to the frame? Are we recharging the battery?
Then, isn't that new amount of charge in excess to the batterie circuit capacity? Is it why we sometime get a static shock when getting off our car?
It seems like a lot of question, but those questions all explore one aspect: what happens to closed circuit charge once the lightning hit to the moment the charge returns to normal? It could also be charge accumulated from air friction, I'm curious to what happens to the new charge added to the circuit since I'm used to closed circuit.
Thanks in advance
