Aircraft refuelling vehicles are crucial for maintaining the fuel supply of aircraft. These vehicles are designed to store, transport, and deliver aviation fuel to aircraft on the ground. They are equipped with reliable fuel - handling systems, including pumps, hoses, and nozzles, which are compatible with different aircraft refueling ports. Safety is a top priority, with features such as emergency shut - off valves, fire - suppression systems, and electrostatic - discharge prevention measures. Aircraft refuelling vehicles also incorporate accurate metering devices to ensure precise fuel delivery. They must comply with strict aviation regulations to guarantee the safe and efficient refueling of aircraft, facilitating smooth air operations.
