What defines a National General Aviation airport?

A National General Aviation airport is classified based on the number of aircraft based at the facility, specifically around 200 based aircraft. This classification helps in identifying the airport's role within the broader aviation ecosystem, ensuring that it meets certain operational characteristics and serves as a hub for general aviation activities. Airports with this level of based aircraft are typically equipped to support a variety of activities, including flight training, private flying, and charter services, thereby contributing significantly to general aviation in the region.

The other choices represent lower thresholds for the number of based aircraft, which do not align with the definition assigned to National General Aviation airports. Airports with fewer based aircraft might serve different functions, such as regional or local general aviation roles, and may not have the same level of operational capacity or community significance as those with around 200 based aircraft.
