Description
Abstract
The Airport Runways database is a geographic dataset of runways in the United States and US territories containing information on the physical characteristics of the runways. The 6073 runways in the dataset are runways associated with the 20347 airports in the companion airport data set. This geospatial data is derived from the FAA's National Airspace System Resource Aeronautical Data Product (Effective 18 January 2008).
Purpose
This data provides users with information about the runway locations and attributes for national and regional analysis applications.

Process step 1
Process description: The creation of this geospatial data layer was completed by RITA/BTS in February 2008. This Shapefile was derived from textual data on the FAA National Airspace System Resource Aeronautical Data CDROM, effective 18 January 2008. The Apt.txt file was converted into three files using the UNIX command grep. The runway table structure was built in Oracle that followed the structure of the facility runway data described in the Apt_rf.txt file. A control file was built for the desired runway data structure and SQL Loader was used to load the data into the database. The degrees, minutes, and seconds' columns were converted into decimal degrees and ESRI products were used to create the runway linear dataset.

Spatial data quality
Horizontal positional accuracy
Horizontal positional accuracy is based on coordinate data provided in the FAA National Airspace System Resource Aeronautical Dataset (Effective 18 January 2008). These coordinate data identify the approximate location of the Airport Reference Point (ARP) as reported by the landing facility on the NFDC (National Flight Data Center) 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.
Estimated accuracy: unknown
