I'd like to emphasize the fact that I am by no means an expert in the internal Canadian situation, so I am not familiar with many of the details the committee is presenting. I don't know about Transport Canada doing certain things. I can only present a conceptual view of how an SMS system should operate based on the general direction that ICAO is following.
I can only reiterate what I've already expressed. It is a basic principle in the management of change that you must introduce change gradually, checking that whatever change is introduced does not introduce additional hazards into the system. You do not remove existing defences until you have other defences in place, and so on and so forth.
If you are presenting a scenario in which you tell me that we have a defence in the system that is a tested defence, a proven defence, and we're entirely removing that defence and replacing it with another defence that we have yet to identify as such a valuable defence, my reply would be that that's very poor management of change. But that's a basic kind of conceptual issue, and that's as far as I would dare go on this particular question.
