Canadian Air Navigation Services Provider (ANSP) NAV Canada will require aircraft operators operating in Class A and B airspace to comply with their new Automated Dependent Surveillance (ADS-B) performance requirements from 23 February 2023.

According to a February 11 announcement of new Nav Canada mandates, the new policy requires that aircraft flying at altitudes above 12,500 feet be equipped with ADS-B Out transponders that meet the applicable standards of the Radio Aeronautics Commission (RTCA) DO -260B. Although Canada has been providing ground-based ADS-B surveillance since 2008 for aircraft flying above 29,000 feet, the new mandate clarifies what type of ADS-B equipment is required and where.

In a statement by email to International Aviationl, a spokesman for Nav Canada said the mandate will take effect through updates that will be added to section 551 of the Canadian Airworthiness Manual. The state agency is also developing a circular aeronautical information on new mandates, and Nav Canada is managing aviation stakeholders to them Service message about the new policy meanwhile.

The spokesman also explained that there are very small differences between the ADS-B Out mandate, which took effect in U.S. airspace on December 31, 2019, and the mandate, which took effect in Canada next year. Nav Canada wants to ensure that aircraft flying in Class A and B airspace will broadcast position updates of their aircraft to Aireon-controlled ADS-B satellite space receivers.

Appropriately equipped aircraft flying below 29,000 feet in the Montreal Flight Information Region (FIR) were first associated with ADS-B Nav Canada space observation in December 2021, and later plans to extend that observation to FIR operators in Edmonton and Winnipeg. year

“The required ADS-B Out avionics performance standards are RTCA DO-260B or later. This requirement can be met either by antenna diversity (use of top and bottom antennas) or by a single antenna capable of transmitting both to the ground. and up to the satellites, ”the spokesman said. “In the U.S., aircraft operating in airspace where a C-mode or S-mode transponder is required must be equipped with ADS-B Out by December 31, 2019. This includes most controlled airspace (classes A, B, C and part E). Outside of US airspace, almost all ADS-B systems operate at 1,090 MHz. ”

The mandate for Canada’s ADS-B Out airspace was postponed to 2019 to address the cost of equipment required by the antenna diversity policy aspect. Initially, Nav Canada proposed a five-year phased approach to its policy, which included a requirement for a variety of antennas – antennas installed at the top and bottom of the fuselage – that would help support its goal of achieving 5 nautical-mile space-based AD surveillance. -B.

The DO-260B standard includes an enhanced Wide Area Expansion System (WAAS) / GPS, accuracy, delay and position prediction, developed based on position and speed for aircraft position prediction, as well as additional cockpit failure signals, among other performance requirements .

According to Nav Canada estimates, approximately 95% of aircraft currently in Class A airspace are equipped with DO-260B-compliant ADS-B Out transponders, while approximately 65% ​​of Class B aircraft in airspace are properly equipped . Raymond G. Bonn, President and CEO of Nav Canada, describes ADS-B as “a major building block for our future airspace and operations”.

“Canada’s mandate for equipment – combined with NAV CANADA’s space surveillance capabilities – will improve security and service,” Bon said. The agency plans to expand its mandate to Class C, D and E airspace with a phased approach starting in 2026. .
