How Do Aircraft Refuelers Conduct the Refueling Process?

Aircraft refueling is one of the most crucial facets of flight operations, ensuring that there is always enough fuel for reaching a destination safely. Typically conducted at the gate of an airport or outside of an aircraft hanger, refueling is carried out by aviation refueler mechanics who are specifically trained in the process. As there are multiple hazards and dangers to aviation refueling, it is important that personnel enact rigorous safety management and proper procedures while carrying out the process. In this blog, we will discuss the steps of aircraft refueling, allowing you to better understand the role that aviation refueler mechanics play for flight operations.

In general, there are two types of refueling operations that may be conducted depending on the size and type of aircraft that is being serviced. For larger airliners such as the Boeing 747, pressure refueling is often used to properly transport fuel into the fuel tanks of the aircraft. With smaller, lighter aircraft such as the Cessna 172, gravity refueling is a more simplistic process that may be utilized instead. Nevertheless, all types of refueling should always be conducted by trained personnel who are knowledgeable about safety precautions, management, and procedures.

As aircraft may differ in their various components, systems, and requirements, an aviation refueler should always first reference the maintenance manual for the specific aircraft in question before conducting any operation. Next, maintenance workers and operators should park the aircraft outside of the hanger or away from any poorly-ventilated area, and extinguishers should always be kept close-by in the case of an emergency. Furthermore, being aware of the placement of the emergency fuel shut off valve is important for maintaining safety throughout the process. As fuel tankers are typically used for refueling, they should be parked near the aircraft and oriented in a direction that allows for them to quickly be driven away in the case of an emergency. Finally, fuel placards, maintenance manuals, and other information from the aircraft should be adhered to to ensure that the correct fuel grade is used. 

Before the hose of the tank is attached to the aircraft for refueling, mechanics should ground both the tank and the aircraft, and the hose should not be dragged alongside its leading edge. Once the nozzle has been grounded, the refueler cover may be removed and fueling can commence. Once the amount of fuel reaches an optimal level by utilizing cockpit gauge readings, the refueler cap can be installed tightly for sealing the tank. At this point, the fueling nozzle can be detached from the aircraft grounding unit and the process of set up can be followed backwards to remove grounding. Before finalizing the procedure, all personnel should ensure that no fuel has come into contact with sensitive body parts such as eyes and skin, and spillages should be immediately attended to as to remove any chance of an ignition hazard. With such processes and safety standards, the operation of aviation refueling can be done quickly and easily.
