Installation Guidance for Domestic Flight Information Services - Broadcast
a. This advisory circular (AC) supports the use of Flight Information Services - Broadcast (FIS-B) weather and other aeronautical data link products for enhanced situation awareness of flight conditions. In this AC, the Federal Aviation Administration (FAA) recommends one way to gain airworthiness approval for the installation of FIS-B avionics equipment. We identify safety and installation requirements for continued airworthiness of aircraft FIS-B avionics equipment, systems, and applications. This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, to gain airworthiness approval for your FIS-B avionics equipment. However, if you use the means described in this AC, you must follow it in its entirety.
b. FIS-B was introduced to improve safety and to increase the utility, efficiency, and capacity of the National Airspace System (NAS). Timely delivery of quality, accurate, and consistent information is utilized by pilots for assisting in operational decisions.
c. This AC was revised to remove outdated information on the Flight Information Services Data Link (FISDL) program and replace with the current FIS-B system while maintaining alternative third party subscription services.
