Which tax is collected under the Aviation Trust Fund?

The passenger seat tax is the correct answer because it is specifically designed to fund the Aviation Trust Fund, which supports various aviation-related programs, including airport improvements and air traffic control systems. This tax is levied on each passenger flying on commercial airlines, and the revenue generated is allocated to enhance and maintain aviation infrastructure, ensuring safety and efficiency in the national airspace system.

In contrast, the automobile registration fee is not connected to aviation financing, as it is generally used for state-level transportation funding. The property tax pertains to local government funding and does not relate to aviation. The fuel surcharge is typically an additional charge that airlines may apply for ticket prices, often influenced by fluctuating fuel costs, but it is not a tax collected specifically for aviation trust or fund purposes. Thus, only the passenger seat tax directly supports the objectives of the Aviation Trust Fund.
