FREQUENTLY ASKED QUESTIONS: ADS-B ADS-B Out The following information is from the Federal Aviation Regulations and Aircraft Owners and Pilots Association website. Question: What ADS-B Out solution is right for your customer? Answer: It all depends on what and where they fly. 14 CFR 91.225 defines the ADS-B requirements for a given airspace: Generally, any airspace that currently requires a transponder will require ADS-B Out. Excluding any aircraft that was not originally certificated with, or not subsequently certified with, an installed electrical system. Installers as well as aircraft owners need to understand the options. The AOPA has a good ADS-B selection tool that will help shops and their customers determine the best solutions for their aircraft. The system is good for light general aviation determinations but has some limitations for larger business aircraft flown internationally. Another limitation of the ADS-B selector tool is its basic focus of ADS-B the FAA's acceptance of an item is communicated to the submitter, the acceptance means that the item meets the FAA's applicable criteria, and that the FAA has no objection to the submitted item. Unless the context of the situation clearly provides otherwise, "accepted by the FAA" does not simply mean receipt by the FAA (i.e., that the item was given to a representative of the FAA and that person received (accepted) it on behalf of the FAA). Note: If an operator implements an item that should Out compliance. While the tool proposes the select the "best" solution, the AOPA's determination of best is minimum regulatory compliance. What the tool does not consider is the added navigation benefit of upgrading the onboard navigator to WAAS for enhanced navigation, or the safety benefit of ADS-B In technology. Nonetheless, the ADS-B Out selector tool is a good starting point. The ADS-B Out selector tool can be found at aopa.org/Pilot-Resources/AircraftOwnership/Technology/ADS-B/ADS-BSelector. In addition, there is a relatively new legal interpretation of flight ID language in 14 CFR 91.227(d)(8) dated Aug. 3, 2017, which effectively states that the aircraft flight ID must correspond with the call sign on the flight plan. So, if the aircraft routinely uses a call sign different than the registration number and the call sign is not static, that is the pilot changes the call sign based on the flight, the owner needs an ADS-B Out system that allows for cockpit configuration of the aircraft's call sign/flight ID. q have been submitted for FAA review and acceptance, but was not submitted, that circumstance alone does not mean the person would be in violation of the underlying regulation requiring the item to be "acceptable." That determination would require an independent analysis of acceptability. At a minimum, however, the person may be in violation of a regulation requiring that the item be submitted.
