That's a very good question, Madam Chair.
We can go into more detail if you would like, but in general, the bottom line is that the science doesn't change. Fatigue is fatigue, and if you're working, science doesn't change. The fatigue doesn't change.
The department has incorporated advice from different industry members on how you can manage the variance between a set of prescriptive regulations that set work hours and the different ways you can manage fatigue more flexibly. We are looking at a dual system, in effect, where you set a minimum mandatory requirement for rest, and then you set a requirement to develop a fatigue management system that will allow the company to say, “This is exactly how, because of our particular unique operations, we will manage fatigue,” in a way that meets the science and not just the operational interest. That is the approach.
