The Federal Aviation Administration’s division of Aeronautical Information Services (AIS) is the single authoritative government source for collecting, validating, storing, maintaining and disseminating aeronautical data concerning the United States and its territories to support real-time aviation activities.

This division provides a Facility Aeronautical Data Distribution System (FADDS), which disseminates each airport’s master record of data. You can read Westchester County Airport's master record of data or go to Airport IQ 5010 for the most up-to-date data.
