ADS-B UPDATE 2024– WHERE ARE WE NOW?
The following is an overview of what ADS-B is, which countries already require ADS-B, and those who have upcoming mandates:
Australia
ADS-B is required for all IFR operations at all flight levels over continental Australia, the Arafura Sea (bounded on the north by airway B598), the Great Australian Bight (bounded on the south by airway Q27/L513), and the Bass Strait (bounded on the east by airway H20 and to the southwest by L513). More information can be found on AIP GEN 1.5, ENR 1 | CASA 61/14
Canada
All flights within Canadian Domestic Class A airspace (essentially all domestic airspace at or above FL180) requires ADS-B. Starting May 16th, 2024 the mandate will then extend to include all Class B airspace. NavCanada will extend this to all Class C, D and E airspace, but this will occur no earlier than 2028.
Canada is different than other countries as there are two equipment requirements that need to be met.
- be equipped with an appropriate transponder with ADS-B Out capabilities that performs to the Minimum Operational Performance Standards of RTCA DO-260B, or newer; and
- have antenna capability for broadcast toward both ground-based as well as space-based ADS-B receivers. This requirement can be met either through antenna diversity (the use of a top and bottom antenna) or with a single antenna capable of transmitting both towards the ground and up towards satellites.
For more information, see AIP ENR 1.6.3.
China
ADS-B is currently required for all flights at and above FL290 if operating in one of the following Urumqi CTA sectors. ZWWWAR02, ZWWWAR03, ZWWWAR05 and ZWWWAR06. For more information, see AIP SUP 08/18.
Colombia
ADS-B is required for all flights within Colombia airspace, at all flight levels. For more information, see RAC 4 4.2.2.6.

- While operating within 12NM of the coastline in the Gulf of Mexico, at or above 3,000 ft. MSL.
Requirements for Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands are slightly different. The class E requirement does not apply to these areas. ADS-B will be required at or above FL180 and at or below FL100, you will need it when:
- While operating within class B or C airspace.
- While operating within 12NM of the coastline.
For the Guam and Northern Mariana Islands (South of 1749N), the only requirements are at or above FL180 and while operating within 12NM of the coastline.
Currently there are no ADS-B requirements for Navassa Island, American Samoa, Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Northern Mariana Islands (North of 1749N), Palmyra Atoll and Wake Atoll.

ADS-B Exemption
ADS-B is required when operating over the U.S. as of Jan. 1, 2020. However, aircraft without the necessary ADS-B capabilities can still operate in U.S. airspace with a single-use route deviation authorization obtained through the FAA’s ADS-B Deviation Authorization Pre-Flight Tool (ADAPT).
To accommodate requests for authorization to deviate from this rule, the web-based tool known as ADAPT was created. As stated in an FAA policy statement (84 Federal Register 12062 dated April 1, 2019), ADAPT is not intended to be used for regular or routine operations by non-equipped aircraft, and your use of ADAPT appears to be regular and/or routine.).
Suppose the FAA denies your requests due to regular and/or routine use. In that case, a one-time authorization may be requested for actual ADS-B equipment installation or ferry of aircraft.
ADAPT facts:
- Applies to U.S. airspace route segments only
- Only valid for a single route
- Applications can be submitted 24 hrs. to 1 hr. in advance of departure
- Authorizations are only valid within a +2 hour window of approved ETD
Universal is now supporting operators with turnkey FAA ADAPT ADS-B Exemption support. For more information on this service, contact our Global Regulatory Services Team.
Vietnam
Currently, ADS-B is required for all flights at or above FL290 within the VVHM FIR whose MTOW is 5,700 kgs (12,566 lbs) or heavier. All flights operating along airways L625, L628, L642, M765. M768, M771, N500, and N892 require ADS-B at or above FL290.
Equipment versions
All mandates in effect currently require your ADS-B equipment to meet the requirements for 1090ES (1090 MHz), while some areas (USA) also allow 978 UAT (978 MHz) equipment to be used. Be sure you have the correct version to operate where you are going.

Tips when traversing regions with ADS-B requirements
Become familiar with ICAO FPL equipment and capability codes (Items 10a/b and Item 18) as well as your performance-based navigation (PBN) codes to help prevent misunderstandings with air traffic control (ATC) while in flight. Know which codes apply to the specific operation. Remember that codes filed in the FPL should represent not only aircraft equipment and capabilities but also those crew members covered by necessary training, authorizations from the state of registry, and working equipment.
Conclusion
Even though some countries do not currently have any ADS-B mandates or any proposals for mandates, they still may provide ADS-B services. ADS-B services are also provided in some non-radar environments with satellite-based ADS-B. If you are non-ADS-B equipped and flying in an area that does not have a mandate but does provide ADS-B services, you still may not get the altitude/route you want. Keep this mentality in mind while flying these days … “better equipped, better served,” as it is no longer just first come, first served.
