Changing NPIAS<\/span> Classification<\/h1>\n

Updates to the NPIAS<\/span> occur every two years. As the roles of airports change, so can their NPIAS<\/span> classifications. Airports and their communities can be aware and take an active role in understanding their NPIAS<\/span> classification. According to the FAA<\/span>’s 2015-2019 NPIAS<\/span> report:<\/p>\n

\n\t\t\t\t\t\t\t\t\t\t“The NPIAS<\/span> report identifies for Congress and the public those airports included in the national airport system, the role they serve, and the amounts and types of airport development eligible for Federal funding under the AIP<\/span> over the next 5 years.”\n\t\t\t\t\t\t\t\t\t<\/p><\/blockquote>\n

It is critical to communicate the importance of the NPIAS<\/span> classification to the community and airport stakeholders. Use this information to tell the story of the airport: of how past, present, and future airport activity shapes the role of the airport. For example, a nonprimary reliever airport most likely would like to communicate about how the airport provides GA<\/span> access to the community that would otherwise be difficult using only the region’s primary commercial service airport. Because inclusion in the NPIAS<\/span> is directly tied to AIP<\/span> funding and other airport services, the airport’s NPIAS<\/span> role may be actively considered when investigating the potential role of the airport in the community. Additionally, the FAA<\/span> makes available previous NPIAS<\/span> reports on their website – use this information to learn how your airport has evolved and changed NPIAS<\/span> classification over time.<\/p>\n

This section outlines the details of how airports enter into the NPIAS<\/span> and when classified in ASSET reports and what factors contribute to their classifications. Use this information to evaluate whether there have been any changes that could potentially reclassify the airport and what actions taken by the airport cause changes in classification. Be sure to explore your airport’s classification in the Identifying Your Airport’s Classification<\/a> section.<\/p>\n

Primary Airports<\/h4>\n
\n

There are four categories of primary airports. The categories are based on the percentage of annual scheduled air service enplanements as compared to nationwide enplanements. Therefore, an airport must have commercial service to be considered a primary airport. To enter or exit this classification, or change hub size designation, an airport must have an increase or decrease in passenger enplanements. Airports that experience a start, modification, or end to commercial service are subject to changes in enplanements that subsequently might cause a change in primary airport status or hub size status.<\/p>\n

Not all airports support commercial service. Market conditions or levels of airport certification and security<\/a> can affect the ability of an airport to offer air service. It is important to keep in mind that your airport can serve many roles<\/a> besides offering air service. To learn more about what affects enplanements, or how to begin air service, see the Air Service<\/a> section of this report. Below are the four categories of primary airports and the criteria for each:<\/p>\n
