CDA Receives Approval to Conduct Fly Quiet Runway Rotation Test 2
Test expected to begin April 30

The Chicago Department of Aviation (CDA) announced today that they have received approval from the Federal Aviation Administration (FAA) to implement a second Fly Quiet runway rotation test. Test 2 is expected to begin April 30 and will be in place for a period of 12-weeks. Each new week would begin on Sunday evening at 10 p.m. or after when demand allows for one arrival and one departure runway.

According to the CDA’s submittal to the FAA, “The purpose of Test 2 is to test the capabilities of the different configurations in response to FAA concerns, as well as test new configurations that were not included in Test 1.” Test 1 was in place from July – December 2016.

Fly Quiet Runway Rotation Test 2 features 10 total configurations in a 12- week rotation. Five of the configurations are modified from the original test. Two of the configuration changes were based on FAA feedback, two based on ameliorating heavy runway use and one based on a desire to reduce the number of mixed-use/single runway configurations.

The goals of the runway rotation test are to: provide near-term relief; reduce impacts 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.

The test also takes into account the following criteria: establishing a rotation plan; alternating east and west flow; avoiding consecutive community impacts; reducing the use of Runway 10L/28R; including Runway 15/33.
The plan includes stakeholder input from the O'Hare Noise Compatibility Commission (ONCC); Suburban O'Hare Commission (SOC); Fair Allocation in Runways Coalition (FAiR); Federal Aviation Administration (FAA).

"I appreciate the work of the Ad Hoc Fly Quiet Committee in their review of the Fly Quiet Runway Rotation Test. The Committee carefully considered the data and results from the first Runway Rotation Program, and provided feedback and thoughtful discussion on moving forward with Test 2. Our goal is to mitigate nighttime noise for communities surrounding O’Hare and to balance the noise impact on those communities," said Arlene Juracek, ONCC Chair and mayor of Mount Prospect. "The work of the Ad Hoc Fly Quiet Committee will carry on as they consider how to continue to achieve these goals for remainder of the interim Fly Quiet period," Juracek said.

"It is important to keep in mind that the alternative to the runway rotation test is the original 1997 Fly Quiet program,” Juracek stated. "Our eventual goal is to develop an Interim Fly Quiet program that would be in effect from the time Runway 15/33 is closed until full buildout, which is anticipated to be in 2021," she said.

Moving forward, the Ad Hoc Fly Quiet Committee is expected to review and discuss a potential Test 3 runway rotation plan that would not include Runway 15/33, which is slated to be decommissioned in spring 2018.
