How is Van Vleck airport categorized?

Van Vleck Airport is classified as a nonpublic use airport primarily because it is not open for public use to all types of aircraft. Nonpublic use airports typically have specific owner restrictions on their use, which may include limited access to certain types of aircraft or specific operational guidelines. These airports are often intended for a specific user group, such as private owners or specific companies, and do not cater to the general public like a public airport would.

In contrast, an option like a public airport is open to all types of flights and airlines without restrictions. Similarly, a restricted military airfield is specifically designated for military operations and not generally open to civilian air traffic, while a recreational use airport may serve mainly small planes or private aircraft for leisure purposes. Van Vleck's classification aligns with the lack of broad accessibility that characterizes a nonpublic use airport.
