ADS-B OUT will become mandatory on January 1, 2020 in USA, UAE and Euro control airspace.

All aircraft must be equipped with ADS-B Out to operate and this includes overflying.

ADS-B enables an aircraft to determine its position and broadcast it in short intervals by means of a data link in radio frequency spectrum.

This functionality is generally referred to as ADS-B Out and has been found to be a cost-effective surveillance technology and will improve safety and efficiency.

Global ADS-B implementations and regulations

There are numerous ADS-B mandates anticipated or already in place in many parts of the world.

USA: The FAA has mandated ADS-B Out capabilities in the continental United States for flights after January 1, 2020, generally in airspace where a Mode C transponder is required today. There is one significant exception; ADS-B also will be required in certain airspace above the Gulf of Mexico.

Class A, B, and C airspace
Class E airspace at or above 10,000 feet msl, excluding airspace at and below 2,500 feet agl
Within 30 nautical miles of a Class B primary airport (the Mode C veil)
Above the ceiling and within the lateral boundaries of Class B or Class C airspace up to 10,000 feet
Class E airspace over the Gulf of Mexico, at and above 3,000 feet msl, within 12 nm of the U.S. coast

Australia: ADS-B Out required for all IFR operations. Foreign-registered aircraft equipped with transponders are exempted below FL290 until June 6, 2020.

Canada: Nav Canada is requiring ADS-B Out equipage with antenna diversity beginning February 25, 2021, at and above Flight Level 180. On January 27, 2022, that ceiling drops to 12,500 feet. No earlier than January 1, 2023, it will add lower “Class C, D, and E airspace as required.” Nav Canada will use the Aireon space-based ADS-B system, of which it is an owner.

Europe: ADS-B Out required for IFR aircraft with a MTOW exceeding 12,566 pounds or maximum cruise airspeed faster than 250 KTAS. Mandatory for new-production aircraft, and must be retrofitted into all aircraft by June 7, 2020.

Hong Kong: ADS-B Out required in all airspace, FL290 and above.

Indonesia: ADS-B Out required, FL290 and above.

Mexico: ADS-B Out required beginning January 1, 2020, in Class A, B, and C airspace; Class E above 10,000 feet msl; and other specified airspace. Requirement effective now in Class E airspace over the Gulf of Mexico, at and above 3,000 feet msl within 12 nm of the Mexican coast.

Singapore: ADS-B Out required on specified airways.

South Africa: ADS-B Out required April 1, 2020, for all IFR operations and for any aircraft first registered or replacing its transponder and flown in Class A, B, D, or E airspace.

Sri Lanka: ADS-B Out required within the Colombo Terminal Control Area (TMA), FL290 and above.

Taiwan: ADS-B Out required in all airspace, FL290 and above.

Vietnam: ADS-B Out required on specified airways.

Regulatory activity is ongoing in China and Saudi Arabia with mandates are expected soon.
