Okay.
I'd like to ask you about a more personal situation. I represent a Calgary riding, and I know both of you are familiar with Calgary approaches.
Since the new runway, the approaches have changed, certainly, from the west side. My riding, which is a half an hour's drive from the airport, is now under a flight path that is giving me no end of grief from my residents, despite what you're saying about reduced noise over the past few years.
One of the things that I asked Nav Canada was why they couldn't move that flight path five miles to the west, where very few people live, and if they needed to, five miles to the east, coming in on the other side, where very few people live. They maintained, if I'm correct, that there were safety issues, but there were also airline requests for those particular pathways.
Can you tell me, in each case, whether moving that approach five miles to the west and east is feasible? If not, why not? If it is, why aren't they doing it?
