What is the most common method of delivering fuel to aircraft?

The most common method of delivering fuel to aircraft is through tank trucks. This method offers several advantages, particularly in terms of flexibility and efficiency. Tank trucks can easily maneuver around an airport and provide timely fuel deliveries to various aircraft, especially during peak operational times. They are capable of refueling multiple aircraft in different locations, making them essential for meeting the fuel demands of busy airports.

In contrast, fueling stations are generally fixed installations that may not provide the same level of immediate service and accessibility that tank trucks can offer. Barrel deliveries and pipeline systems are less common for regular operations; barrels are typically reserved for backup supplies or specific situations, while pipeline systems are large-scale installations that may not be present at all airports or are used more in larger airport setups. Therefore, tank trucks remain the primary method due to their practicality and adaptability in responding to the dynamic nature of airport operations.
