The O’Hare Noise Compatibility Commission (ONCC) Ad Hoc Fly Quiet Committee met today and voted to recommend a second Fly Quiet Runway Rotation Test. The original test took place from July – December 2016. The proposed Fly Quiet Runway Rotation Test 2 now moves to the full ONCC membership for approval at its March meeting. If approved, the second test could start as early as this spring.

 

At today’s meeting, Chicago Department of Aviation (CDA) staff presented the proposed Fly Quiet Runway Rotation Test 2, which features 5 configuration modifications from the original test. Two of the configuration changes are based on FAA feedback, two based on ameliorating heavy runway use and one is based on a desire to reduce the number of mixed-use/single runway configurations. All proposed configurations have been tentatively reviewed by FAA and have been determined as feasible to implement.

The two original configurations that the FAA had issue with included one where aircraft taxiway movements on the ground conflicted with 9R arrivals in the air, and one where 10C departures needed to taxi across an active runway.

The goals of the original runway rotation plan remain the same for the second test: 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 criteria for the new test, like the original, include 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 proposed Fly Quiet Runway Rotation Test 2 will now go to the full ONCC membership at its March 10 general meeting. Prior to that meeting, CDA will develop a proposed rotation schedule using the modified configurations.

At their February 8 meeting, the Ad Hoc Fly Quiet Committee received the Draft Final Report on the 2016 Runway Rotation. The final report was provided to the committee today. Data from the first test showed that 67% of operations during the Fly Quiet runway rotation period used a designated runway. The average time in overnight Fly Quiet rotation over the 25 weeks was 7 hours, with an average start time of 10:42 pm and stop time of 5:42 am.

CDA also presented citizen feedback results of the Fly Quiet Runway Rotation Test Survey, which was made available to the public via the CDA web site. Survey results showed that 61% of the total survey responses believed that the Test should continue.

The next ONCC general meeting is Friday, March 10 at 8:00 am at Café La Cave, 2777 S. Mannheim Road, Des Plaines, IL.
