The Chicago Department of Aviation (CDA) today formally submitted the Fly Quiet Runway Rotation Plan for O’Hare International Airport to the Federal Aviation Administration (FAA) for review and approval. The proposed plan, which would be the first of its kind in the country, is designed to achieve a more balanced distribution of noise exposure during the overnight hours for Chicago and suburban communities surrounding O’Hare.

The Ad Hoc Fly Quiet Committee met on Tuesday, June 14 for an update briefing from the Chicago Department of Aviation (CDA) regarding the six-month Runway Rotation Program (RRP)scheduled for O'Hare International Airport in early July.

The CDA reported that they are working closely with the FAA to implement the plan as early as possible this summer. The goal of CDA is to balance airfield construction, scheduled for both the north and south airfields, with the RRP schedule. Construction will impact the rotation schedule and an additional alternate runway may have to be in place.

The committee reviewed the Fly Quiet II Adherence Metrics designed to measure the test, which included operational percentages, actual noise levels and citizen feedback. CDA will post the start and end time of Fly Quiet and the average duration of time for each weekly period on a designated website.

The ONCC Residential Sound Insulation Committee was presented with the results of the Historical Homes Pilot Program. CDA will meet with FAA and Illinois State Preservation Agency to discuss the results of the pilot program. A number historical homes identified in Program Phase 17C include historical homes. These homes are located in the Norwood Park Historical District.

Historic Homes Pilot Program Summary

Chicago Department of Aviation consultant presented the 1st Quarter 2016 Fly Quiet Report and a review of Airport Noise Capacity Act (ANCA)to the ONCC Technical Committee at the May meeting.

Under the Fly Quiet Report, the most used nighttime arrival runway was 27L with 38 percent or approximately 48 arrivals; Runway 28C had 23 percent of nighttime arrivals. Runway 28R had the most nighttime departures with 38 percent or approximately 39 operations; Runway 32L had 27 percent of nighttime departures. American, United, Spirit and Envoy airlines were the commercial carriers with the highest number of nighttime flights.

Nighttime flight track deviations have been reduced considerably due to increased awareness of the Fly Quiet program by the O’Hare Air Traffic Control Tower management. ONCC continues to meet with tower managers to review compliance to voluntary procedures.

By an overwhelming majority, the O’Hare Noise Compatibility Commission (ONCC)  today approved a weekly nighttime runway rotation plan for O’Hare International Airport. 
The Fly Quiet Runway Rotation Plan, developed by the Chicago Department of Aviation (CDA), in consultation with CDA and Suburban O’Hare Commission (SOC) aviation experts, seeks to establish a weekly runway rotation program at O’Hare during overnight hours that is designed to achieve a more balanced distribution of noise exposure for Chicago and suburban communities. 

Two O'Hare community noise groups, the Suburban O'Hare Commission and the Fair Allocation in Runways Coalition, have endorsed the Chicago Department of Aviation's proposed Fly Quiet Runway Rotation Plan.  The plan calls for 12 weekly rotation periods of one arrival and one departure runway during the Fly Quiet II nighttime hours.  The ONCC will vote on the runway rotation plan on May 6. If approved, it will be submitted to the FAA and the plan will be tested for a six-month period.
