In light of the ongoing supply chain issues felt throughout the industry, NAV CANADA has issued a 90-day grace period for the first phase of ADS-B (automatic dependents surveillance–broadcast) Out Performance Requirements Mandate in Canadian domestic Class A airspace. The deadline for ADS-B Out compliance in Canada is August 10, 2023. Operators have between August 10, 2023 - November 8, 2023, to comply.

No AOR or Aviation Occurrence Reports will be filed during this grace period for aircraft not equipped to comply with the Canadian ADS-B Out mandate.

To learn more about the requirements to request accommodations to fly in Canadian airspace, where ADS-B is mandatory, read the Performance Requirements issued by NAV Canada.  

Duncan Aviation has the authorizations and capabilities to assist Canadian operators with their ADS-B compliance, performing transponders modifications at the Avionics & Instrument Shop in Lincoln, NE, and the replacement and installation of the equipment at 30 Satellite Avionics Shops across the U.S.
