What is the most common method for delivering aircraft fuel?

The most common method for delivering aircraft fuel is through tank trucks. This method is favored in airport operations due to its flexibility and efficiency. Tank trucks can easily maneuver in and around airport facilities, allowing for direct delivery to the aircraft as needed. They are equipped with pumps and hoses that facilitate quick fueling processes, which is crucial given the busy schedules of flights.

Using tank trucks is particularly advantageous because they can transport different volumes of fuel, making them suitable for both small regional airports and larger international hubs. Additionally, tank trucks help ensure that fuel can be readily available close to the aircraft, minimizing delays and optimizing turnaround times.

Other methods, such as fuel pipes, are typically used for fixed infrastructure where continuous delivery is required. However, they may not be practical for all airport layouts, especially where space is limited. Fuel tankers and railcars are less common for immediate aircraft refueling due to logistical limitations and the time required to transfer fuel from those vehicles to the aircraft.
