How do large airport refuelling systems work? As I am sitting on board my plane and have been informed that there may be a three-hour delay due to a pressure problem in the fuelling system at the destination, it seems like an appropriate moment to ask: how do these systems at large airports (in this case, Amsterdam Schiphol) work?

Apparently, it is an airport-wide problem affecting all flights that need refuelling.


How and where is fuel stored?
How is it delivered to the aircraft?
What sort of technical problem with pressure could affect an entire airport the size of Schiphol?

Both systems shown above work well for big airports. The system depicted at the bottom is called a Hydrant Fueling System.
