Special notice

Elevated noise due to Boeing tests
Over the next several months, King County International Airport may experience elevated noise due to engine runs by The Boeing Company. These engine runs are a critical part of the company’s certification flight testing for the 787 and 747-8 aircraft, which will be at the airport in higher numbers than normal during this time.

The engine runs will be kept to non-curfew hours (between 7 a.m. and 10 p.m.) as much as possible, but Boeing may have an occasional need to do them after curfew hours. This is most likely to happen early in the testing program, and the company will follow all proper protocols and issue notifications.

Noise management

Fly Quiet program

The Fly Quiet Program is a voluntary program designed to encourage aircraft operators to use flight patterns and procedures that reduce noise in communities in the neighborhood of King County International Airport. The airport’s Noise Office is a timely resource for in-depth analysis and credible data about flight operations and noise monitoring reports.

Information for pilots about KBFI’s Fly Quiet program is available in our For pilots section.

Noise monitoring

The purpose of the Noise Monitoring program is to provide reliable and consistent noise metric data to measure the success of noise reduction strategies in communities surrounding the airport. The program collects noise data from six permanent noise monitors strategically located in neighborhoods near the airport.

For more information about monitoring activities near you and other aspects of the noise monitoring program, please send your questions or comments to the King County international Airport’s Noise Office.

Flight tracking

King County International Airport/Boeing Field added flight tracking to its noise monitoring system in 1998. This system has been upgraded twice—in 2005 and 2008—in order to have the best available technology to identify the actual flight path aircraft operators use when departing and arriving at KBFI. This comprehensive information database system also identifies all other flights originating at nearby airports. The flight tracks are generated from the FAA Air Traffic Control (ATC) system’s radar data, which provides the aircraft’s “footprints” in the sky. KBFI’s Noise Office correlates calls to its Noise Information Line with flights and noise measurements. In combination, flight tracking and noise monitoring improve the airport’s ability to determine which operators are in compliance or deviating from FAA regulations and/or KBFI’s Fly Quiet program flight procedures.
