What is NASR, The FAA's System for Managing Aeronautical Information?
NASR contains the current information upon which Air Traffic Control and other FAA activities depend. NASR supports the management of NAS data used by the FAA, chart producers (including Jeppesen), military and other Government entities to produce a variety of aeronautical publications. Downloads from Foreflight use this data, but may be reformatted to suit the application and would not come directly from any NASR database.

In addition, NASR data is accessed by commercial air carriers, flight planners, and flight systems developers as required by FAA regulation to support the safety-of-flight mission.

The data is available on a 28 day subscription basis. Legacy flat files show the data content, though other forms are available. Definitions for each table are here. The tables are:
