I'd have to say that I don't think I could comment on that in terms of the changing regulations. I do know that some airports have different clearances. I know, for example, that here in Norman Wells, it's a quarter of a mile visibility, because they have a certain approach called an LPV, I believe.
I think across the north I'm just not too familiar with the different approaches in different communities. In our particular area, we just got instrument approaches into some of our communities in the last eight years or so.
I wish I could comment, but I don't know enough about it. Myles Cane would be a great person to talk to about that. He'll be on next week, I think. You may have to ask him.
