Aircraft Monitoring System

The Port of Seattle has a flight track monitoring system and operates 24 permanent noise monitors. Together, these systems collect and store flight data and noise levels from individual aircraft.

This system enables the port to regularly monitor airline compliance with noise abatement procedures and investigate citizen inquiries. As data from the monitors is accumulated and analyzed, changes and trends can be identified. 


Notice WebTrak Users

The Port of Seattle is upgrading its flight tracking system equipment and installing new noise monitors at all existing monitor locations.

During the upgrade, transmission of aircraft sound levels to WebTrak may be temporarily interrupted, resulting in sound levels not appearing. We expect to have the upgraded system in place by June 2015 when you will experience better and more reliable aircraft viewing and monitoring at Sea-Tac Airport.

Please watch for more information about the new service soon. If you have questions about the system upgrade, please contact the Noise Programs Office at (206) 787-5393.
