Aviation Safety Letter: Special Issue 1/2024

Previously, the ASL was only available in PDF, but starting with issue 3/2019, it’s now also available in HTML. This change makes it easier to share articles with others—but more importantly, will make it easier to search for specific topics.

Welcome to this Special Issue of the Aviation Safety Letter

Message from Andy Cook, Associate Director-General, Civil Aviation, Transport Canada, team lead of the approach ban safety initiative, currently developing new regulations and guidance material that is intended to enhance safety during instrument approaches.

Why We Need to Act Now: The Compelling Safety Case

Why adherence to the charted visibility is important to reducing risk; why the current situation in Canada needs to be addressed; and the solutions that are under development to address the identified safety issues.


Being Led Down the Garden Path: Understanding the Human Factors Contributing to Low Visibility Approach Accidents

The increased level of risk that exists when approaches are conducted with less than the charted visibility; an analysis of accidents that occurred with less than the charted visibility and the critical human factors that are common to them; and how the new, simplified regulations will help improve safety during instrument approaches and align Canada with the global aviation community.

Runway Level of Service: Important Changes to Simplify and Align

An overview of runway level of service: the functions it is intended to serve, how it is determined and how this information is made available; the situation today: an explanation of our current hierarchy of visibility reports and the opportunities for improvement; and the way forward: the solutions that are being implemented to address the identified safety issues.


Supporting the New Approach Ban Regulations: TP 308 Changes and NAV CANADA Collaboration

This article will explain the important role of NAV CANADA in the collaborative effort to facilitate the introduction of the new regulations. One of their significant contributions is the updating and improving of charted visibility on Canadian instrument approach procedures.

Looking to the Future: Enhanced Flight Vision Systems and Other New Technologies Enabling All-Weather Operations

The introduction of EFVS and other new technologies enabling lower approach minima will greatly improve the operational flexibility of operators and ensure the continued improvement to the ability of pilots to land safely at aerodromes in poorer visibility conditions.


Answers to Stakeholder Questions About Aerodrome Operations and the Approach Ban Safety Initiative

This article will provide answers to some of the questions that we’ve already received. We hope that it will also encourage stakeholders to provide their questions and comments through the Canadian Aviation Regulation Advisory Council process.

Canadian Stakeholders Have a Voice: Understanding the Consultation Process

The key players in aviation rulemaking in Canada; an overview of how the Canadian Aviation Regulation Advisory Council (CARAC) is managed and how it functions on a day-to-day basis; and how you can contribute to important aviation regulatory initiatives that are led by Transport Canada Civil Aviation (TCCA).


Summing Up and Moving Forward

Having the ability to provide feedback during the regulatory development process is the right of every Canadian, and stakeholders are strongly encouraged to submit their comments, suggestions and questions through the CARAC.
