Aircraft fuel bowsers are mobile refueling units used to store and transfer aviation fuel to aircraft. These bowsers are designed with robust fuel - storage tanks and powerful pumping systems to ensure efficient fuel delivery. They are equipped with high - precision metering devices for accurate fuel measurement, which is essential for aircraft performance. Safety features are a key component, including emergency shut - off valves, fire - suppression systems, and electrostatic - grounding devices to prevent static - induced fires. Aircraft fuel bowsers are also designed to be maneuverable, allowing them to access different aircraft parking positions on the tarmac. Their reliable operation and safety features make them an important part of airport refueling operations.
