Among the issues identified during a 2018 overrun investigation was, “The rules governing instrument approaches in Canada are too complex, confusing and ineffective at preventing pilots from conducting approaches that are not allowed, or banned, because they are below the minimum weather limits,” according to Canada’s Transportation Safety Board. In other parts of the world, a flight crew is not allowed to begin an instrument approach if the reported weather is below published minimums for a given approach except in Canada, where “flight crews are permitted to conduct approaches in visibility conditions that are below what is published.”
Transportation Safety Board of Canada Says IFR Approaches Are Confusing
Key Takeaways:
- Canadian regulations governing instrument approaches are uniquely complex and confusing, permitting pilots to conduct approaches even when weather conditions are below published minimums, unlike international standards.
- This regulatory complexity contributed to a February 2018 King Air accident in Quebec where a pilot, misinterpreting the rules, attempted an approach in dangerously low visibility, leading to a runway overrun.
- Following the accident, Canada's Transportation Safety Board (TSB) recommended that Transport Canada simplify approach and landing minima to improve safety and prevent similar incidents.
