Aircraft fueling is the process of adding fuel to an aircraft to ensure it has enough energy for its flight. This involves using specialized equipment, such as fuel trucks or hydrant systems, to transfer fuel from storage tanks to the aircraft's fuel tanks. The type of fuel used is typically Jet A or Jet A-1, which are kerosene-based fuels designed for jet engines. Safety is a critical aspect of aircraft fueling. Ground crews must follow strict protocols to prevent spills, fires, or other hazards. They use grounding cables to prevent static electricity buildup and ensure that the fueling process is conducted in a controlled environment, minimizing risks to personnel and equipment.
