Which of the following is an example of non-aeronautical revenue?

• A. Landing fees
• B. Airfare sales
• C. Air traffic control fees
• D. Fuel taxes

Answer: (D)

Non-aeronautical revenue refers to income generated by an airport from sources that are not directly related to the operation of aircraft or the provision of air transportation services. This type of revenue typically comes from activities such as retail, parking, concessions, advertising, property leasing, and other commercial ventures that utilize airport facilities but do not involve the aeronautical aspects of airport operations.

Fuel taxes represent a form of non-aeronautical revenue because they are collected on the sale of fuel, which is not a service provided directly by the airport itself, but rather a charge associated with the consumption of fuel by airlines or other users on airport property. Unlike landing fees or airfare sales, which are directly tied to flight operations, fuel taxes are categorized under broader revenue-generating activities that support the airport's overall operations without being tied to air traffic or flights specifically.

This distinction highlights how non-aeronautical revenue is integral to the financial sustainability of airports, providing funds that can be allocated to maintenance, development, and enhancement of facilities that support both aeronautical and non-aeronautical operations.
