WebTrak for YVR allows residents to see for themselves flight activity over much of Metro Vancouver. Using radar data received from NAV CANADA and noise data collected at 20 noise monitoring terminals stationed throughout Metro Vancouver, WebTrak displays a map of the region and current flight and noise activity. A simple visual key identifies aircraft type, elevation and noise level, and whether the aircraft is arriving or departing. With easy-to-use features and menu options, anyone with access to the Internet can replay historical flight activity within the past 30 days, locate their residence on the map to determine the distance from aircraft in flight, and, if they wish, register a comment or concern about a particular flight.
