The dataset provides information on the primary surfaces of Iowa airports. The primary surface extends 200 feet beyond each end of the runway, but when the runway has no specially prepared hard surface, the surface ends at the end of that runway.

The dataset provides information on the conical surfaces of Iowa airports. The conical surface extends outwards and upwards from the boundary of the horizontal surface at a slope of 20:1 for a horizontal distance of 4,000 feet.

This dataset provides information on the transitional surfaces of Iowa airports. The transitional surface extends outward and upward at right angles to the primary and approach surfaces at a slope of 7:1.

This dataset provides information on the transitional surfaces of Iowa airports. The transitional surface extends outward and upward at right angles to the primary and approach surfaces at a slope of 7:1.

The dataset provides information on airport approach surfaces. The approach surface is longitudinally centered on the extended runway centerline and extends outward and upward from each end of the primary surface. An approach surface is applied to the end of each runway based upon the type of approach available. (Slopes can vary from 20:1, 34:1, 40:1 or 50:1).

This dataset provides information on airport runway locations and information in Iowa including contact information, location details and more.

The Airport Runways database is a geographic dataset of runways in the State of Maryland containing information on the physical characteristics of the runways. The 6716 runways in the dataset are runways associated with the 19721 airports in the companion airport data set. This geospatial data is derived from the FAA's National Airspace System Resource Aeronautical Data Product (Effective 17 March 2013).

Data available online through the Arkansas Spatial Data Infrastructure (ASDI) at http://gis.arkansas.gov. The subject file represents the Arkansas portion of a geographic data set of runways in the United States and US territories containing information on the physical characteristics of the runways. The 8550 runways in the data set are supposed to include all of the runways associated with the 6734 airports in the companion airport data set Airports, 1998 (BTS). Data were obtained from the Federal Aviation Administration's (FAA) National Flight Data Center (NFDC) 5010 landing facilities data (January 1999). 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 scale is unknown.
