Hello!
I am very interested in this topic and have other questions:
What happens for example, if the grounding point of the aircraft or refueling vehicle no longer has any electrical conductivity (corrosion / incorrect installation ) or the bonding cable is broken, to what extent is there still a risk of fire or if, for example, the cable is attached to a painted surface?
What happens if the cable comes loose during refueling or does a cable only have to be connected at the beginning of refueling to compensate for the potential difference?
How often do such fires occur? What is more problematic jet or avgas?
You always read that fuels are becoming safer and if I remember correctly you "never" hear of any such incidents that lead to fires?
In short, does this grounding during refueling serve as a safety device to prevent fires - during refueling - or does grounding have any other safety relevance? What about the electrical systems on board? Or is that irrelevant?
I would be interested
Thanks for answering.
