If you’ve lived in a certain community or city for a period of time, you might take for granted what newcomers to the area would not necessarily know- and one of those things are flight paths.
The Calgary International Airport (YYC) reached new heights in 2008, with passenger volume at 12.5 million passengers and 125,000 tonnes of air freight, making YYC the third busiest airport in Canada, after Toronto and Vancouver. With a fourth runway scheduled to begin construction in 2011 and complete in 2014, it’s important to know the paths those planes will take if you’re planning on renting or buying in the area.
The contours that encircle the map (see above) are determined using the Noise Exposure Forecast (NEF) system approved by Transport Canada. This tool scientifically predicts annoyance and noise from aircraft. The contours range in value from relatively low noise (NEF 25) to relatively high noise (NEF 40).
One way to find out if a property is within a contour is to look it up at the City of Calgary website, under “My Property” (Update: Link no longer active)
Two examples of properties within the contour are below:
However, I find it best just to speak with neighbours in the area directly. They’re living there and would know best what, if any disturbances there are with aircraft.
