It works for the Air Canada Pilots Association because they have an agreement with their operator. They have the agreement, but it's not in regulation. It's just another example of flight data monitoring. I've heard that you'll land somewhere and maintenance will show up and say that they're there to change that fuel pump, and the pilot will ask what fuel pump? They saw a couple of hours ago that it was starting to go, so they know in advance. It's a good tool.
