Review of Surveillance Requirements - Exploring Future ADS-B Requirements in Canadian Airspace – National
Scope of Study
The Study will:
- Evaluate whether requiring aircraft to be equipped with ADS-B Out in low-level controlled airspace (below 12,500 feet ASL) is operationally and technically justified, considering both benefits and drawbacks.
- Assess the role of space-based ADS-B in low-level airspace, including its limitations in higher-density traffic environments, and the potential use of ground-based ADS-B receivers to mitigate these limitations.
- Examine impacts to airspace users, including the challenges for non-equipped aircraft to access ADS-B airspace and consequences to accessibility, safety, and efficiency.
- Review options for targeted ADS-B requirement in selected Class D and E airspaces, where traffic levels or operational complexity may justify surveillance.
- Consider stakeholder perspectives — particularly those of smaller commercial and general aviation operators — with respect to the requirement for antenna diversity, technical feasibility, and operational impacts.
- Define implementation timelines for previously approved high-level airspace (above FL600).
- Explore the potential of supporting the provision of information broadcast services.
- Explore the role of electronic conspicuity (EC) devices in supporting the principle of “See, Be Seen, and Avoid.”
Consultation
The study will include formal stakeholder consultations to determine if any issues exist and what mitigations may be required if changes are recommended.
