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.

The CDA and the FAA are encouraging residents to provide feedback on the test by completing an online survey that can be found at http://www.airportprojects.net/flyquiettest. 
Feedback from Test 3 will assist the Chicago Department of Aviation in developing an Interim Fly Quiet Runway Rotation plan that may be in place from the time of Runway 15/33 closure (Spring 2018) through full time of Runway 9C/27C opening (Fall 2020). CDA staff plans to conduct an environmental analysis and perform modeling in the fall and winter of 2017 to develop the interim plan, and residents' input from Test 3 will be an important element of the process.

The original runway rotation test ran from July - December 2016; Test 2 was in effect from April 30, 2017 - July 23, 2017; Test 3 will run until October 15.

The criteria for the first two tests included: establishing a rotation plan; alternating east and west flow; avoiding consecutive community impacts; reducing the use of Runway 10L/28R; and utilizing Runway 15/33.

Once Test 2 was underway, the ONCC Ad Hoc Fly Quiet Committee began to review the proposal for Test 3, which made improvements on Test 2 (as recommended by the FAA) as well as excluded the use of Runway 15/33 so residents could experience a rotation plan that could potentially be in place once the runway is decommissioned in the spring of 2018.

Several ONCC members said that they favored the rotation plan, because their constituents appreciated the effort to balance the impact of nighttime air traffic.

“We have received a positive response on the runway rotation tests,” said ONCC Chair Arlene Juracek. “Residents are reporting that they have experienced relief from nighttime noise as a result of the runway rotation. We are asking residents to continue to report on their experiences with the runway rotation tests by completing the online survey. It is important that we know how the test is effecting them,” Juracek said.

ONCC Technical Committee Chair Cathy Dunlap and ONCC Executive Director Jeanette Camacho attended the Chicago Airline Cargo Managers Association meeting on July 12.

Technical Committee Chair Cathy Dunlap explained the Fly Quiet Quarterly report and how important Fly Quiet is to the O'Hare's neighboring communities.

The Airline Cargo Managers Association invited ONCC to future meetings for updates regarding the Fly Quiet program.

The test is scheduled to start immediately following the conclusion of Fly Quiet Runway Rotation Test 2, which has been in effect since April 30, 2017 and will end July 23, 2017. The purpose of conducting a third test is to test in real time a runway rotation without the use of Runway 15/33 which is slated to be decommissioned in the spring of 2018.

On June 16, ONCC members were invited to attend a workshop entitled "Noise 101" in order to gain a base level understanding of how the airport operates, how aircraft noise is measured and how those measures relate to sound insulation programs.

The Technical Committee met on June 13.

CDA staff presented the following:

  • Update on Portable and Permanent Noise Monitors
    Installation process continues on new permanent noise monitors. CDA waiting for permitting process to be complete for all sites so concrete work can all be completed in the same week. Complete installation expected to be completed within the next 22 months.

The membership of the O’Hare Noise Compatibility Commission voted today to approve a third Fly Quiet Runway Rotation Test. The test would be expected to start immediately following the conclusion of Fly Quiet Runway Rotation Test 2, which has been in effect since April 30, 2017 and will end July 23, 2017.

The purpose of conducting a third test was to test in real time a runway rotation without the use of Runway 15/33 which is slated to be decommissioned in the spring of 2018.
