Starting January 1, 2020, you must be equipped with ADS-B Out to fly in most controlled airspace:
|B||Generally, from surface to 10,000ft mean sea level (MSL) including the airspace from portions of Class Bravo that extend beyond the Mode C veil up to 10,000 feet MSL (i.e.- SEA, CLE, PHX)|
|C||Generally, from surface up to 4,000ft MSL including the airspace above the lateral boundary up to 10,000ft MSL|
|E||Above 10,000ft MSL over the 48 states and DC, excluding airspace at and below 2,500ft AGL|
|Over the Gulf of Mexico at and above 3,000 feet MSL within 12 nm of the coastline of the United States|
|Airspace within 30 nautical miles (Mode C veil) at all Class B locations from the surface up to 10,000 feet MSL|
Any airspace that requires the use of a Transponder today will on January 01, 2020 also require aircraft to be equipped with a Version 2 ADS-B Out system. This can be either a 1090ES (DO-260B) ADS-B system or a UAT (DO-282B) ADS-B system.
For aircraft operating above FL180 (18,000 ft.) or to comply with ADS-B mandates outside the United States, you must be equipped with a Mode-S transponder-based ADS-B transmitter. For aircraft operating below 18,000 ft. and within the United States ADS-B rule airspace, you must be equipped with either a Mode-S transponder-based ADS-B transmitter or with UAT equipment.
Interactive ADS-B Airspace Map
Download the Equip ADS-B Google Earth map (KMZ) to look at the location of ADS-B rule airspace at your home base and where you fly. Pan and zoom to different locations and turn on the various capabilities the map includes:
- 3-dimensional depictions of rule airspace, airports, and temporary flight restrictions in real time
- Overlays of ADS-B surveillance coverage — airspace where ATC can see aircraft transmitting ADS-B Out information at altitudes of 500′, 1,500′, 3,000′, 5,000′ and 10,000′ AGL
- Non-radar airspace where aircraft transmitting ADS-B can be seen by ATC
