Airports have fuel transfer systems that push fuel from remote storage tanks to aircraft on the ground.
The jet fuel storage tanks can be miles away from the airport. Fuel transfer systems get the fuel to a loading port.
There are miles of fuel pipes that run underground and aboveground near airports.
Fuel access ports are positioned where aircraft are loaded for flights.
A truck that carries metering, pumping and filtering equipment connects to the fuel access point and the jet being refueled.
The truck’s system removes air from the fuel, filters for sediment, meters the output and loads the jet.
