Ad Hoc Fly Quiet Committee Votes To Recommend Interim Fly Quiet Plan to Full Membership

November 17, 2017

The O’Hare Noise Compatibility Commission (ONCC) Ad Hoc Fly Quiet Committee voted today to recommend an Interim Fly Quiet plan to the full O’Hare Noise Compatibility Commission membership.

Chicago Department of Aviation (CDA) consultants presented three runway rotation options to the Committee, which ultimately chose Option A, essentially the same runway rotation plan that was followed in Fly Quiet Runway Rotation Test 3.

The goals outlined in the Fly Quiet Runway Rotation Plan Goals and Guidelines included: to provide near-term relief, to reduce impacts to the highest impacted communities, and to provide predictability to the extent possible. One of the strategic guidelines outlined in all three of the Fly Quiet Runway Rotation Test Goals and Guidelines was to avoid consecutive community impacts. A motion was made during the meeting to remove the consecutive impact consideration, but this was unanimously voted against.

This meant the only remaining option was Option A, as the other options would have resulted in consecutive community impact. Option A features an 8 week rotation plan with six configurations arranged to alternate each week between parallel and diagonal runways, and also rotating east flow and west flow. Option A estimates operations on parallel runways to be at 74%, with operations on diagonal runways at 26%. These estimates are based on Test 1, 2, and 3 results, and do not take into account future construction/maintenance schedules.

Option B included two parallel runway configurations and one diagonal configuration from Option A, but also incorporated a hybrid model with one parallel and one diagonal runway in each configuration.
Option C was a six week rotation plan with two parallel configurations and one diagonal configuration. Runway usage in both Option B and Option C was estimated at 83% on parallel runways and 17% on diagonal runways. Again, these estimates are based on Test 1, 2, and 3 results, and do not take into account future construction/maintenance schedules.

CDA staff noted that any rotation plan would be impacted by construction scheduled to take place on the diagonal 4/22 Runways. Construction on Runway 4L/22R was initially expected to take place in 2018, but CDA staff stated today that this work would take place in 2019, with construction on 4R/22L planned for 2020.

In addition to Options A, B and C presented by the CDA, the City of Elmhurst presented an additional alternative. The Elmhurst option was similar to Option C that the CDA presented, featuring a six week rotation plan with two parallel and one diagonal configuration.

Suburban O’Hare Commission (SOC) Consultant JDA provided a report to the committee with analysis of Runway Rotation Tests 2 and 3 and recommendations for the Interim Fly Quiet Plan.
JDA recommended Option A as SOC’s preferred option because they believed it achieved the most equitable balance possible until longer runways are commissioned. They stated that Options B, C and the Elmhurst option all shift more operations onto the parallel runways than existed prior to the rotation and therefore defeat the purpose of rotating runways.

The proposal now moves to the full ONCC membership at a special meeting on December 8 at 8:00 am at Café la Cave, 2777 S. Mannheim Road, Des Plaines, IL.

If approved by the full ONCC, the CDA and Federal Aviation Administration (FAA) will begin environmental analysis. The FAA review process will include public hearings and public comment period.

The Fly Quiet Runway Rotation Test 3 started the evening of July 23, 2017.

Test 3 will be in place for a period of 12 weeks. Each new week will begin on Sunday evening at 10:00 p.m. or after when demand allows for one arrival and one departure runway.

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.

Complete schedules and more information is available at: www.flychicago.com/flyquiettest

Residents are highly encouraged to fill out the survey in order to provide feedback.

Fly Quiet Runway Rotation Test Survey



June 23, 2016

The Chicago Department of Aviation (CDA) submitted the proposed Fly Quiet Rotation Plan to the Federal Aviation Administration ("FAA") earlier this week. The proposed start date of the program is now July 6, 2016. This is going to be a 25 week test period. The Village had previously reported that the O'Hare Noise Compatibility Commission ("ONCC") approved a 6-month test for overnight flights from 11:00 PM to 5:30 AM. Air traffic controllers and pilots are to ensure planes arrive and depart on different parallel and diagonal runways during the test period. Ten different configurations labeled “A” through “J” will be used on a one week basis. This began on July 6th and will conclude around Christmas Day 12/25/16.  Configurations “D”, “G” and “H" (see the SOC Newsletter below to view these options) look particularly favorable for Schiller Park. These will be in place for the weeks of 7/17, 7/24, 8/7, 9/4, 9/18, 10/9, 10/16, 10/30, 11/27, and 12/11.

O’Hare Runway Rotation Plan Gets Green Light

Test goes into effect on Wednesday, July 6, 2016

The O’Hare Noise Compatibility Commission (ONCC) announced today that the Federal Aviation Administration (FAA) has approved a six-month test of a Fly Quiet II Runway Rotation Plan to bring nighttime noise relief to residents living near O’Hare International Airport. 

The Fly Quiet II Runway Rotation Plan, developed by the ONCC in conjunction with  the Chicago Department of Aviation (CDA), Suburban O’Hare Commission and  the Fair Allocation in Runways Coalition, will achieve a more balanced distribution of overnight noise exposure for Chicago and suburban communities.

The test consists of 12 weekly primary and secondary runway configurations that will be rotated over 25 weeks and goes into effect on Wednesday, July 6, 2016. ONCC membership approved the weekly runway rotation plan in May by an overwhelming majority vote.

“I appreciate the CDA’s efforts to mesh the runway rotation schedule with airfield construction, slated for both the north and south airfields this summer,” said ONCC Chair and Mount Prospect Mayor Arlene A. Juracek. “By providing a rotation plan that includes both primary and secondary runway choices for each weekly rotation, we ensure that despite construction the Fly Quiet II Runway Rotation Plan  will bring a measurable amount of nighttime noise relief to the most impacted communities,” she said.

For each week, a primary runway operating configuration is designated with an alternate configuration designed to accommodate factors such as wind or construction if needed. Each of the 12 weekly runway designations consists of either two runways (one arrival and one departure runway) or one mixed use runway used for both arrivals and departures.

The rotation schedule along with a survey for residents to provide test program feedback will be posted on www.flychicago.com/flyquiettest  for the public to view online along with other pertinent information, such as the start and end time of Fly Quiet II and the average duration of time for each weekly period.

"The ONCC takes the feedback from affected residents very seriously, and will work to address the needs of the communities most impacted by nighttime noise identified during the test period,” said Juracek. “Engaging everyone impacted during the test period is critically important to the ONCC. We are looking forward to reviewing the data and formalizing an interim Fly Quiet program that will best address the region's needs prior to full build out of the O'Hare Modernization Program."

In the end, ONCC will provide a recommendation to the FAA as to whether or not the Interim Fly Quiet II rotation plan should be implemented beyond the six-month test period and until the closure of Runway 14R/32L. The FAA will make the final decision.



April 25, 2016


In spring, easterly winds become more prevalent in the Chicago area. This year is no exception as recently, we have begun experiencing an increasing number of days with all or mostly easterly winds. When this occurs, O’Hare is in “East Flow” (Arrivals on 9L, 10C, & 10R; Departures on 9R, & 10L). This with the combination of more activities outdoors in the warmer temperatures  is likely to result in additional noise complaints.

For a detailed explanation of easterly winds becoming more prevalent see below explanation from Illinois State Climatologist Dr. Jim Angel:

 “The combination of more warm fronts to the south and high pressure to the north, along with the increased incidence of the lake breeze off Lake Michigan, results in a significant rise in the frequency of easterly (southeast, east or northeast) winds during the spring (March, April and May) season. Transitioning from the winter season, March retains much of the "winterlike" cold frontal wind patterns that give a westerly (southwest, west or northwest) flow 49 percent of the time (36 percent is easterly). However, by April, temperatures over the city more often warm into the 50s, 60s and 70s while Lake Michigan waters remain in the upper 30s and lower 40s. This creates a huge temperature differential which in turn initiates the cooling easterly "Lake Breeze" effect. Easterly winds are observed 41 percent of the time in April and 44 percent of the time in May.”

We don’t completely accept their explanation because there are certainly times when there seems to be no wind at all and our homes still get hammered with take-offs. Therefore we continue to encourage our residents to call the O’Hare Noise Complaint Line at 800-435-9569 or visit www.oharenoise.org and log your complaints on line.
