The Work Of An Airport Fueler: A Behind-The-Scenes Look

Aviation fuel is a highly specialized petroleum-based fuel that powers aircraft. Airports receive their fuel via pipelines or tanker trucks, depending on their size and location. For example, large international airports like London Heathrow are connected to underground networks of fuel pipes, while smaller airports like Bristol receive fuel by tanker truck. Airport fuelers play a crucial role in ensuring aircraft are fuelled efficiently and safely. They are responsible for the timely delivery of fuel to aircraft, adhering to strict safety protocols to prevent spills and fires. Given the high volume of fuel required by aircraft and the potential for delays if an airport runs out of fuel, the role of an airport fueler is essential to the smooth operation of any airport.

Aviation fuel is delivered to airports via pipelines or trucks

Aviation fuel is a petroleum-based fuel that is used to power aircraft. It is refined before being delivered to airports and contains additives to enhance or maintain properties important to fuel performance. Airports store large volumes of aviation fuel, which is then transferred to aircraft via one of two methods: overwing or underwing.

Aviation fuel is typically delivered to airports via pipelines or trucks. Some large international airports receive their fuel supply via underground pipelines, such as the Colonial Pipeline, which is 5,500 miles long and can deliver 100 million gallons of fuel per day. Airports like London Heathrow are connected to an underground network of fuel pipes that link the entire country, a system carried over from World War 2.

However, not all airports are served by pipelines. Smaller airports and those without pipeline access, such as Bristol Airport, receive their fuel supply via trucks or tankers. These bulk trucks transport fuel to fill up the storage tanks at the airport. Even airports with pipeline access may occasionally need to bring in fuel by truck, such as when there are issues with the pipeline or the fuel quality.

The delivery method can impact the efficiency and reliability of fuel supply. Pipeline deliveries can take several hours to reach the airport, as seen with Manchester Airport's 30-mile pipeline, which requires 4-6 hours for fuel to travel from the refinery. Truck deliveries, on the other hand, can be more immediate but may require constant truck access to meet the high fuel demands of large airports.

The process of filling aircraft with fuel involves several steps and can be completed within a short time. For example, the Boeing 767 Freighter can be filled with up to 24,000 gallons of fuel in just 28 minutes. Fire safety is a critical aspect of the fueling process, with fire extinguishers and specially trained airport firefighting forces present to handle any fuel-related emergencies.

Airports store aviation fuel in tanks

The size of the airport and its fuel requirements influence the chosen method of fuel transportation and storage. Large international airports often receive fuel through pipeline systems, such as the Colonial Pipeline, which stretches for thousands of miles and delivers a high volume of fuel daily. Smaller airports, on the other hand, may rely on fuel trucks to fill their storage tanks.

The safe storage of aviation fuel is of utmost importance due to its environmental impact and the potential for catastrophic engine failure if contaminated. To address this, fuel storage tanks have features such as sloping floors to facilitate water drainage and prevent the growth of microbes that can degrade fuel quality. Additionally, all fueling vehicles must carry equipment to control fuel spills, and airport firefighting forces are specially trained to handle fuel-related incidents.

The process of transferring aviation fuel from storage tanks to aircraft involves either the overwing or underwing method. Airports with permanent piping infrastructure can directly transfer fuel to large aircraft parking areas. The efficient management and distribution of aviation fuel are crucial to meeting the demands of dynamic airline schedules and ensuring that aircraft are not stranded due to fuel shortages.

Fire extinguishers and specially trained firefighting forces are required at airports to handle fuel spills and fires

Aviation fuel is highly flammable and can cause severe environmental damage. Fire extinguishers must be present at any fuelling operation, and all fuelling vehicles must carry equipment to control fuel spills. Airport firefighting forces are specially trained and equipped to handle aviation fuel fires and spills. They are responsible for ensuring the safety of airport staff, passengers, and aircraft in the event of a fuel-related emergency.

The role of a firefighter at an airport is critical in maintaining the safe operation of the airport. They are often the first responders to any fire or fuel spill incident on the airport premises. Their primary responsibility is to extinguish fires and prevent them from spreading. This involves not only putting out the flames but also using specialised equipment to contain and clean up fuel spills promptly.

Airport firefighters are trained to handle a variety of scenarios, including aircraft emergencies, structural fires, and hazardous material incidents. They are familiar with the unique challenges posed by aviation fuel and know how to mitigate its risks effectively. Their training covers a range of firefighting techniques, emergency response procedures, and the use of specialised equipment designed for aviation environments.

In addition to their firefighting duties, airport firefighting teams also play a crucial role in fire prevention and safety inspections. They conduct regular checks of airport facilities, fuelling operations, and aircraft to identify potential fire hazards. By working closely with airport management and other emergency response teams, they help develop and enforce fire safety protocols, ensuring that the airport maintains the highest standards of fire safety and compliance with relevant regulations.

The presence of fire extinguishers and specially trained firefighting forces at airports is essential to mitigate the risks associated with fuel spills and fires. Their expertise and quick response capabilities help minimise damage, protect lives, and maintain the smooth operation of the airport. Their role extends beyond emergency response, contributing to a comprehensive fire safety framework that safeguards the entire airport community.

Aviation fuel is then transferred to aircraft via overwing or underwing methods

Aviation fuellers are responsible for fuelling aircraft before and after flights. They do this by operating fuelling trucks, hydrant carts, and stationary carts to transfer aviation fuel to aircraft. This can be done via overwing or underwing methods.

The overwing method involves fuellers pulling out a hose from the truck and coupling the nozzle to the aircraft's fuel panel. This often requires climbing a ladder or stool and lifting the heavy nozzle above their head. Once the fuelling is complete, the nozzle must be removed, and the ladder or stool climbed again to reach the nozzle.

The underwing method is used for smaller aircraft and involves attaching a smaller hose to the fuel panel or pulling out a hose and climbing a ladder while holding the hose and nozzle during fuelling.

Regardless of the method, strict safety rules must be followed, and fuellers must be trained to handle jet fuel and high-octane aviation gas safely. They must also comply with health and hazardous materials handling regulations and perform quality control checks on equipment.

Fuellers may also be responsible for other tasks, such as assisting with ramp services, performing lavatory services, and consulting with pilots to ensure accurate fuel quantities.

The type of aircraft determines the steps and time taken to refuel

The two main refuelling systems are probe-and-drogue and flying boom. The probe-and-drogue system is simpler to adapt to existing aircraft, while the flying boom offers faster fuel transfer but requires a dedicated boom operator. Tankers equipped with multipoint hose-and-drogue systems can simultaneously refuel two or more aircraft, reducing refuelling time by up to 75% for a four-aircraft package. The USAF KC-10 has both a flying boom and a separate hose-and-drogue system, but only one can be used at a time. The KC-135 and KC-135FR tankers can be field-converted to a probe-and-drogue system using a special adapter, retaining the articulated boom with a hose/drogue at the end instead of a nozzle.

The type of aircraft also determines the steps taken during the refuelling process. Before refuelling, preparatory measures are essential, including assessing fire safety requirements, confirming the type and quantity of fuel, and ensuring fuel quality. Aircraft ground refuelling guarantees flight safety by maintaining optimal weight and balance, preventing issues from excessive fuel loads, and enabling the aircraft to leave the airport. During refuelling, the correct type of fuel equipment must be used, and safety protocols must be followed. After refuelling, accurate record-keeping of fuel types, quantities transferred, and equipment used is crucial for compliance and tracking fuel consumption.
