National Flight Data Center Web Portal

NFDC Web Portal forms are used to collect aeronautical information, detailing the physical description and operational status of components of the National Airspace System (NAS). The information is distributed via the National Flight Data Digest (NFDD), a daily electronic (.pdf) publication available at no charge to the general public, government, military, and private producers of aeronautical publications. (https://www.faa.gov/air_traffic/flight_info/aeronav/aero_data/NFDD/). The information is used to update government, military, and private aeronautical database, charts, publications, flight management systems, and in-flight tracking products. The information collected includes, but is not limited to, data regarding airport associated city, CTAF, UNICOM, facility use, runway lighting, airport sketches and diagrams, proposed aircraft call signs, and general remarks. Reporting of this information in mandatory, i.e. airport operators are required to submit any changes to their facilities that might appear on aeronautical charts or publications. This is considered to be reporting of information vs. record keeping or disclosure. Information is collected on a continual basis.
