a. This AC provides guidance for the installation and airworthiness approval of Automatic Dependent Surveillance - Broadcast (ADS?B) Out equipment in aircraft.
b. This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, to install ADS-B Out equipment. However, if you use the means described in this AC, you must follow it entirely.
c. This AC is primarily intended for installations compliant with 14 CFR § 91.227. Airworthiness compliance will be evaluated based on the applicable intended function rule (e.g., 14 CFR §§ 23.1301, 25.1301, 27.1301, 29.1301) recognizing that the intended function is to meet the equipment requirements in 14 CFR § 91.227. It is possible to receive airworthiness approval for your ADS-B Out system without demonstrating that it complies with 14 CFR § 91.227, however we strongly discourage this type of installation unless the installation is in accordance with the criteria for ADS-B Out in foreign non-radar airspace (e.g., Approved Means of Compliance (AMC) 20?24). Applicants using this AC to install ADS?B systems that are not compliant with 14 CFR § 91.227 must follow all aspects of this AC and propose alternate means as necessary to the FAA.
