In October 2017, the Chicago Department of Aviation (CDA) completed a third and final nighttime Fly Quiet Runway Rotation Test at O'Hare International Airport. These test programs were designed to provide residents and business owners near the airport near-term noise relief, reducing the impact of noise on highest impacted communities, and providing airplane arrival and departure predictability.
In February 2018, the CDA requested the Federal Aviation Administration (FAA) to review and approve an Interim Fly Quiet Runway Rotation Plan (IFQ) designed to take effect in late 2018 and remain in place until November 2020 when new runway 9C/27C is scheduled to be commissioned. The IFQ recommendation includes use of the same nighttime runway configuration from the recently completed third Fly Quiet test program.
Feedback from the FAA, air traffic controllers, members of the O'Hare Noise Compatibility Commission, and Suburban O'Hare Commission, and runway data compiled from the previous three test programs was used to develop the recommendation to the FAA. More information about the Fly Quiet programs is available on the O'Hare Noise Compatibility Commission website and on the Fly Quiet Test website.
