The ONCC Ad Hoc Fly Quiet Committee met on August 30, 2017.

On August 24, 2017, ONCC members were invited to participate in a tour of the O'Hare Airfield. Members visited the new Northeast Cargo Ramp, Firefighter Training Area, viewed snow removal equipment, construction of new runway 9C/27C and construction of new gates at Terminal 3.


The CDA is publishing a slight change to the Runway Rotation Test schedule for Test 3 Week 5 (Week of August 20th). The FAA is working on a navigational aid called a localizer for Runway 9R-27L. 

For more information about a localizer, please visit the CDA website here

The only change to Week 5 is an added green arrow to depict a departure construction alternative, specifically departures on Runway 10L in the Secondary configuration. All versions of the Fly Quiet rotation scheduled have been updated posted to the CDA’s project website.

At the Technical Committee Meeting on August 15, 2017, CDA staff presented an update on noise monitors, reviewed the 2nd Quarter Fly Quiet Report, presented recent Airfield Changes and Relocation of the GRE.

O’Hare Airport's Fly Quiet Runway Rotation Test 3 started the evening of July 23, 2017.O’Hare Airport's Fly Quiet Runway Rotation Test 3 started the evening of July 23, 2017.

This is the third in a series of runway rotation tests designed to provide near-term relief, reduce nighttime noise to the highest impacted communities and provide predictability by publishing a rotation schedule that allows citizens to predict periods of relief to the extent possible.

Test 3 was approved by the O'Hare Noise Compatibility Commission (ONCC) general membership in June, and was then submitted by the Chicago Department of Aviation to the Federal Aviation Administration for its approval. The test will be in place for a period of 12 weeks and incorporates 5 runways: 4L/22R, 9R/27L, 10L/28R, 10C/28C and 22L/4R. Test 3 does not include runway 15/33 which is slated to be decommissioned in spring 2018. Each new week will begin on Sunday evening at 10 p.m. or when demand allows for one arrival and one departure runway.
