ICAO and NFPA The ICAO and the NFPA airport classifications are somewhat different than the FAA classifications. The United States airspace system's classification scheme is intended to maximize pilot flexibility within acceptable levels of risk appropriate to the type of operation and traffic density within that class of airspace – in particular to provide separation and active control in areas of dense or high-speed flight operations. Airport Classification . In this method there are two criteria, the first criteria is airport classifications For design purposes, airports are classified based on the aircraft they accommodate. ICAO and NFPA use a classification based from Category 1 through Category 10. The FAA is the governing body for aviation in the United States. FAA Classification: Based on Aircraft Approach Speed. aviation airports. The first 3 categories describe smaller airports that do not have air carrier commercial service based on the FAA equivalent. In order to provide an understanding of how Indiana’s airports fit into the national airport system, the FAA airport categories are discussed below before a new ISASP category structure is presented. Historically, airport managers were responsible for counting the number of based aircraft and reporting the totals to FAA and state inspectors. FAA codes are more often than not the same as IATA codes, minus the first letter (usually K, unless in Hawaii, Alaska, or overseas territories), although there are some cases where IATA and FAA codes mean different airports … For the purpose of stipulating geometric design standards for the various types of airports and the functions which they serve, letter and numerical codes and other descriptors have been adopted to classify airports. C) Federal aviation administration (FAA) classification of airport The Federal Aviation Administration (FAA) has its own method for classifying whether an airport as a hub or non-hub. The most commonly accepted classifications by the FAA (Federal Aviation Administration), ICAO (International Civil Aviation Organization), UK, and Canada are shown in the illustration. Airport Classification ICAO Classification: Based on Length of Runway. FAA Office of Airports Marc Tonnacliff ARFF Specialist Federal Aviation Administration 800 Independence Ave. SW Airport Safety and Standards, AAS-300, Room 618 Washington, DC 20591 (202) 267-8732 Fax (202) 493-1416 FAA Technical Center Keith Bagot ARFF Research Program Manager ANG-E621, Bldg 296 Atlantic City International Airport, NJ … For airports in the FAA National Plan of Integrated Airport Systems (NPIAS), the number of based aircraft can affect airport classification and can factor into eligibility for airport improvement projects. The broadest classification is civil and military, international and domestic, and so on. The National Plan of Integrated Airport Systems (NPIAS) identifies nearly 3,310 existing and proposed airports that are included in the national airport system, the roles they currently serve, and the amounts and types of airport development eligible for Federal funding under the Airport Improvement Program (AIP) over the next 5 years. The federal classification for airport can sometimes overlap an in these two documents. As part of the airport pavement management system (APMS) update for the Iowa Department of Transportation, Aviation Bureau (Iowa DOT), Applied Pavement Technology, Inc. (APTech) determined Pavement Classification Numbers (PCNs) for runway pavements at Harlan Municipal Airport and other airports included in the 2018 phase of the APMS update. In Table-1 given the category of airports if used methods of grouping the FAA.
