NAV CANADA has announced that they will be implementing a mandate for aircraft ADS-B to be qualified for space-based ADS-B Out when operating in Canadian domestic airspace above 12,500 feet. Space-based ADS-B has been available in portions of Canadian domestic airspace for some time above FL290 and has increased surveillance capabilities with an accompanying increase in safety. Canada and other countries are starting to implement the requirements for space-based ADS-B.

Effective March 1, 2022, North Atlantic tracks at FL330 and below will no longer be published. As a result, flights operating at FL330 and below will be free of the organized track structure. Although there have never been restrictions for random routing crossing tracks, this will aid the operators who plan not to cross tracks at active flight levels.

From 25 Feb 2021, Datalink-equipped aircraft may again cross anywhere in the NAT HLA airspace.


Datalink mandated airspace is again  FL290-FL410.  Non-Datalink-equipped aircraft may only cross the NAT HLA at any altitude provided the flight is constrained to the surveillance airspace.   Additionally, the Non-Datalink aircraft must have operational ADS-B while over Greenland and conduct the flight under VHF coverage.
