NAV CANADA Implements ADS-B Mandate in Canadian Class A Airspace

NAV CANADA, the country's air navigation service provider, has announced the implementation of the Automatic Dependent Surveillance-Broadcast (ADS-B) performance requirements mandate for aircraft operating in Canadian Class A interior airspace.

Key Points:

• ADS-B Technology: Aircraft equipped with the appropriate transponder transmit their exact position and altitude twice per second to a network of 66 satellites fitted with ADS-B receivers. These data are then relayed to NAV CANADA's air traffic control surveillance screens. This technology allows controllers to offer pilots more efficient and environmentally friendly routes and enhances the company's ability to support search and rescue efforts.

• Statement from Jeff Dawson: Jeff Dawson, Deputy Vice-President, Operational Support, highlighted the significant step in implementing the ADS-B mandate in Class A airspace. He emphasized the role of Transport Canada and industry stakeholders in this achievement, which is part of a phased approach to realize the full potential of increased surveillance coverage.
• Historical Context: In 2019, NAV CANADA first utilized this groundbreaking satellite technology in Canadian Class A interior airspace above 29,000 feet, building on the successful use of the technology in unsupervised airspace over the North Atlantic. Furthermore, the mandate is expected to come into effect in May 2024 for aircraft in Class B interior airspace and as early as 2028 for other interior airspace classes, following further consultations with stakeholders.

• Towards Trajectory-Based Operations: Jeff Dawson added that the ADS-B mandate is a significant step towards trajectory-based operations. Precise aircraft positioning will transition spacing from less efficient temporal standards to standards based on distance between aircraft. , reducing aircraft operators' fuel consumption.
• Support for ADS-B Implementation: To support the ADS-B mandate's implementation, NAV CANADA, in partnership with Aireon - which deployed the world's first air traffic surveillance system using satellite-based ADS-B across a network of 66 low-Earth orbit satellites - created the Public ADS-B Performance Report (PAPR). Designed to assist aircraft operators, this report provides them with data on the functionality of onboard ADS-B equipment. NAV CANADA has added Aireon's data to a searchable database on its website, allowing Canadian airspace users to input their aircraft information to assess their system's functionality.

Best Aviator Sunglasses for Men and Women in 2023

Aviator sunglasses have been a popular style for decades, and for good reason. Originally designed for pilots to protect their eyes from the bright sun at high altitudes, aviator sunglasses have become a fashion staple for both men and women.
