ADS-B FAA Mandate
The FAA began implementing NextGen timelines in 2009 starting with ADS-B. The ADS-B ground-station infrastructure was fully operational by the end of 2014. The FAA has mandated that almost all aircraft flying in United States airspace above 10,000 feet must be equipped with ADS-B Out by January 1, 2020.
As with the current transponder operating requirements, the ADS-B rule requires operators to have ADS-B Out avionics installed and operating in order to fly their aircraft in the busiest airspace, as described below:
- Class A, B, and C airspace.
- All airspace at and above 10,000 feet Mean Sea Level (MSL) over the 48 contiguous United States and the District of Columbia.
- Within 30 nautical miles of airports listed in 14 CFR §91.225, from the surface up to 10,000 feet MSL.
- For Class E airspace over the Gulf of Mexico from the coastline of the United States out to 12 nautical miles, at and above 3,000 feet MSL.

On May 27, 2010, the FAA published new rules contained in 14 CFR §92.225 and §91.227 mandating airspace and avionics performance requirements after January 1, 2020. Advisory Circular AC 20-165A issued in November 2012 provides guidance for the installation and airworthiness approval of ADS-B Out systems in aircraft. The mandated avionics perform the ADS-B Out function, which transmits precise location and other information about the aircraft to ground stations and other aircraft equipped with ADS-B. The rule does not mandate ADS-B In avionics, which enable other services available with ADS-B. Aircraft outfitted with ADS-B In avionics can take advantage of broadcast services of data, like graphical and text-based weather, traffic advisories, and other aeronautical information, in the flight deck. The ADS-B rule mandates ADS-B Out avionics performance when operating within designated affected airspace, giving aircraft owners approximately seven years to equip their aircraft. The ADS-B rule, like current transponder operating requirements, requires operators to have ADS-B Out avionics installed and operating in order to fly their aircraft in the busiest airspace.
It is important to note that the ADS-B rule did not change or affect current transponder or RVSM maintenance requirements.
