I mainly travel in the north. Most of the runways, the one in Chibougamau, for example, are controlled from Quebec City. Not very long ago, a King Air plane crashed in Chibougamau. We don't know whether it was because of a lack of experience on the part of the pilots or because of weather conditions that frequently change in the north. In addition, there was no controller on site.
Could the fact that no one can see the usable length of runway for the aircraft that is preparing to land be a factor? When control is done from Quebec City, they see what's going on in the air, but not on the runway.
