Abstract: A system and method for servicing aircraft on a flight line away from a maintenance terminal comprises a first set of vehicles for servicing the aircraft directly and a second set of vehicles for servicing the service vehicles. The first set of vehicles requires fuel and oil in order to operate; the second set brings fuel and oil to the first set to make it unnecessary for the first set to halt aircraft servicing in order to return to the terminal. The second set of vehicles includes a trailer with three tanks, one for jet fuel, one for diesel fuel and one for oil. The tanks are placed on a catch basin carried on a trailer. Each has a tapered bottom with a drain and an inlet port at the top with a funnel-shaped collar. Each tank also carries its own transfer hose with a manual pump and has a sight guage, ground cable, lifting rings and lifting handles.
