Well explained. Thank you very much.
At smaller airports, if refueling is done from canisters, or if the grounding / bonding cable is forgotten in a hurry, isn't that a major hazard?
Do I understand correctly that there is double and triple protection if the bonding cable is out of order for any reason?
Firstly through anti-static earthing strips on the underside of the refueling vehicle (earth belt) and secondly through the earthing in the refueling hose itself?
