Aviation fuel is often dispensed from a tanker or bowser which is driven up to parked aeroplaneshelicopters. Some airports have pumps similar to filling station that aircraft must taxi up to. Some airports also have permanent piping to parking areas for large aircraft and

Regardless of the method, aviation fuel is transferred to an aircraft via one of two methods: overwing and underwing. Overwing fuelling is used on smaller planes, helicopters, and all piston-engine aircraft. Overwing fuelling is similar to car fuelling — one or more fuel ports are opened and fuel is pumped in with a conventional pump. Underwing fuelling, also called single-point, is used on larger aircraft and for jet fuel exclusively. For single-point fuelling, a high-pressure hose is attached and fuel is pumped in at up to 50 PSI. Since there is only one attachment point, fuel distribution between tanks is either automated or it is controlled from a control panel at the fuelling point or in the cockpit. As well, a dead man's switch is used to control fuel flow.
