Aviation Fuel Hydrant
An underground pipe network that carries jet fuel from the airport tank farm to pits on the apron, so large aircraft can be fueled without a fleet of tank trucks.
What it does
A hydrant dispenser vehicle connects the pit to the aircraft. EI 1540 guides the design, testing and maintenance of these systems, including automated integrity testing of the buried hydrant network.
