Simplifying Airspace Operations: Understanding AC 700-039 Issue 03 and RVSM Requirements

Transport Canada has recently released the third issue of Advisory Circular (AC) 700-039, dated February 29, 2024, focusing on the “Requirements to Obtain Reduced Vertical Separation Minimum (RVSM) Specific Approval.” This crucial document aims to guide air operators through the process of acquiring the necessary approval to conduct flights within RVSM-designated airspace, ensuring safer and more efficient use of our skies.

RVSM airspace is a critical component of modern aviation, allowing aircraft to fly at closer vertical intervals, increasing airspace capacity, and reducing fuel consumption. However, to navigate this space safely, specific approvals are required, dictated by rigorous training, equipment, and maintenance standards.

Key Updates in AC 700-039 Issue 03

The latest issue of AC 700-039 introduces several important updates designed to align with global aviation standards and technological advancements:

Terminology Alignment: In accordance with International Civil Aviation Organization (ICAO) guidelines, the term “Specific Approval” now supersedes “Special Authorization” for CARs Part VII air operations. This change aims to standardize the language used in aviation regulations globally, promoting clarity and understanding.
Technological Advancements: Reflecting NAV CANADA’s shift to space-based Automatic Dependent Surveillance-Broadcast (ADS-B) and the implementation of the Canadian ADS-B mandate for Class A airspace in 2023. This update underscores the industry’s move towards more sophisticated surveillance technologies that enhance the safety and efficiency of air navigation.
RVSM Height Monitoring Update: The document highlights the phase-out of the three remaining height Aircraft Geometric Height Measurement Elements (AGHME) systems and the transition to an ADS-B based height monitoring system by the North American Approvals Registry and Monitoring Organization (NAARMO). This shift signifies a significant step forward in utilizing advanced technology for more accurate and reliable height monitoring within RVSM airspace.

Importance for Air Operators

The AC 700-039 Issue 03 is not just a regulatory update; it’s a roadmap for air operators to navigate the complexities of RVSM operations safely. By adhering to the outlined requirements for training, equipment, and maintenance, operators can ensure compliance, safety, and efficiency in their operations.

Furthermore, the circular encourages operators to stay informed about the latest aviation safety information and regulatory changes by subscribing to the Transport Canada Civil Aviation e-Bulletin. This resource provides valuable updates on ACs, newsletters, and other essential safety information, helping operators maintain the highest standards of safety and compliance.

In conclusion, AC 700-039 Issue 03 is a testament to Transport Canada’s commitment to aligning with international aviation standards and embracing technological advancements for safer skies. By following the guidelines and staying informed, air operators can contribute to a more efficient, safe, and sustainable future for Canadian aviation.
