I'm familiar with fueling ops at a small station, but I'm wondering how things are different at a large one. I know many large airports now have fueling systems integrated into the ramp. Fuel flows underground to the gates and equipment at the gate connects to the plane to deliver fuel. What is the technical term for these systems? I can't seem to remember it.
I know PHL doesn't have an integrated system at all terminals. Are there some PHL terminals that do have it?
How common are these systems? What other large airports do not have them?
What is the nature of the equipment to deliver the fuel plane-side? Is it simply a pump, hose and a gauge that draws the fuel up from underground? Who owns and operates this equipment, the airport or a private company?
Finally, have these integrated systems proven beneficial in lowering fueling costs and boosting efficiency?
Thanks everyone for your knowledge.
