Why are there planes over my neighbourhood?
Planes are likely to fly over most of Montréal’s neighbourhoods at any time during the day. The majority of aircraft flying over Montréal take off from or land at Montréal–Trudeau. There are other airports nearby, however, including the one in St. Hubert. Often, planes flying over Lachine, for example, are departing from or arriving at St. Hubert. After takeoff, jets may bank left or right, depending on their destination, as soon as they reach an altitude of 915 metres (3,000 feet); propeller planes, meanwhile, must turn as soon as possible after takeoff to clear the way for jets, which fly faster. Aircraft landing at Montréal–Trudeau must follow a very precise trajectory, directly in line with the runway and on a 3° angle of descent. Since there are six runways (three physical runways that can each be used in two directions), there are six approach corridors, which take aircraft over many neighbourhoods.
