Désolé, I can't say with any confidence that this would have prevented that Ethiopian accident. First, the Ethiopian Airlines Flight 302 investigative report has not been released yet, so we still have things to learn with regard to this accident. We still have more to garner from here. We won't know whether the crew operating that aircraft used that unique Canadian procedure and could have recovered from what they were experiencing. That's something we won't be able to determine.
What we do know is that this measure helped to reduce.... By memorizing those procedures, what we were doing was decreasing the reaction time for crews on Canadian-operated aircraft to recognize and respond to this sort of event happening in the flight deck, and that may have or would have helped them prevent that sort of issue from escalating.
I'd be in no position to determine if that would have prevented the Ethiopian Airlines accident.
