Description:
Abstract: 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.
Purpose: The database provides locational and attribute
information for use in national and regional cartographic
and spatial analysis applications.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: 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.
Logical_Consistency_Report: 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.
Completeness_Report: 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
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: 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.
