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.

 

The implementation of the mandate will be done in phases. The first phase mandates Canadian Class A and B airspace capability above 12,500 feet as of February 23, 2023. Class B, C, D, and E Canadian airspace will eventually apply this mandate. Still, nothing will be mandated before 2026 in these airspaces to allow operators to have time to acquire the needed equipment or modifications.

 

Many aircraft may already be qualified or require minor modifications to comply, while others may need more comprehensive changes. 

To meet the ABS-B requirements of the mandate, your aircraft will need the following:

  • A transponder with ADS-B Out capability meeting the requirements of RTCA DO-260B or subsequent.
  • Antennae that can broadcast upward to satellite ADS-B receivers using a 1090 MHz extended squitter. Accomplishing this requires either a top and bottom antenna or a single antenna that can transmit to both ground and satellite receivers. This requires antenna diversity.
  • A reporting and serviceable enabled TCAS.

 

NAV CANADA AIC 12/22 has information where space-based ADS-B coverage is available now below FL290.
