FAA Airport Surveys
*******************

The National Geodetic Survey, in accordance with a series of interagency agreements with the Federal Aviation Administration (FAA), provides airport geodetic control, as well as runway, navigational aid, obstruction, and other aeronautical data that is critical to the operation of the National Airspace System. Most of these data are source information obtained using field survey and photogrammetric methods. These data are used to develop runway approach procedures and obstruction charts.

NGS contracts survey work for Area Navigation Approach (ANA) charts to the private sector on a funds available basis. Survey specifications are provided in AC No: 150/5300-16B(2019) and the older "FAA No. 405, Standards for Aeronautical Surveys and Related Products," 4th edition, September, 1996; and "General Specifications for Aeronautical Surveys, Vol. I. Establishment of Geodetic Control on Airports." Funding for these surveys is provided to NGS by the FAA. This latest version of OPUS Projects (OP) fully supports the bluebooking process for FAA surveys by producing a b-file and g-file, and automatically invokes ADJUST in the required series of network adjustments. All files required for a successful submission of an airport survey to NGS are fully supported by OP.
