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

• A. Parking
• B. Landing fees
• C. Salaries
• D. Aircraft fuel sales

Answer: (A)

Non-aeronautical revenue comes from activities not directly tied to aircraft operations. Parking fits this because it provides a service to passengers and visitors and uses airport facilities for general public use, not to enable flight operations. In contrast, landing fees are charged for using the airfield and support aircraft operations (aeronautical), and fuel sales are a service directly related to enabling flights (also aeronautical). Salaries are expenses, not revenue. So parking is the example of non-aeronautical revenue.
