National Transportation Atlas Database metadata states –
“The Public-Use Airports database is a geographic point database of aircraft landing facilities in the United States and U.S. Territories. Attribute data is provided on the physical and operational characteristics of the landing facility, current usage including enplanements and aircraft operations, congestion levels and usage categories.”
This data set was compiled by Bernardin-Lochmueller and Associates, using data believed to be accurate; however, a degree of error is inherent in all data. This product is distributed "AS-IS" without warranties of any kind, either expressed or implied, including but not limited to warranties of suitability of a particular purpose or use. No attempt has been made in either the designed format or production of these data to define the limits or jurisdiction of any federal, state, or local government. These data are intended for use only at the published scale or smaller and are for reference purposes only. They are not to be construed as a legal document or survey instrument. A detailed on-the-ground survey and historical analysis of a single site may differ from this data.

Acknowledgment of the Bureau of Transportation Statistics National Transportation Atlas Database would be appreciated in products derived from this data set.
“Airport attributes were obtained from the Federal Aviation Administration (FAA) National Flight Data Center Airport Master Record (NFDC 5010) database and the Office of Airline Information (OAI). Some airport features in this version are not assigned Site Numbers (SITE_NO). These are airports where the location identifier (LOCID) did not match any current record in the NFDC data. These features have no corresponding records in any attribute file. They were not deleted from this version in anticipation of performing a more thorough review.”
“All point records are represented by a single coordinate pair and a unique feature identifier -- the landing facility's location identifier (LOCID) and Site Number (SITE_NO) assigned by the FAA.”
“Landing facilities in this database consist of those identified in the NFDC 5010 database to be either publicly owned, or privately owned but open to the public, or owned by the U.S. military. The following landing facilities have been excluded: private landing facilities not open to the public, glider ports and ultra light landing facilities, as well as landing facilities that do not have a current LOCID assigned to them.”

“Horizontal positional accuracy is based on coordinate data provided in the NFDC 5010 database. These coordinate data identify the approximate location of the Airport Reference Point (ARP) as reported by the landing facility on the NFDC 5010 form. According to NFDC guidelines, the location of the ARP should be reported to a horizontal accuracy of one arc second of latitude and longitude. However, the accuracy of these reported coordinates are not verified by FAA. The records were loaded into a GIS and checked for any unusual or obviously erroneous locations.”
