The ONCC Ad Hoc Fly Quiet Committee met on Thursday, September 21, 2017. 

The Chicago Department of Aviation (CDA) presented the final Fly Quiet Runway Rotation Test 2 Report, highlighting some of the changes that had been made based on feedback they received from members and consultants. CDA consultants provided supplemental data on Wide Body Operations on Runways Less Than 10,000 feet and Aircraft Fleet Mix Report for Operations on Non-Scheduled Runways, as per the request of Committee members at the previous Ad Hoc Fly Quiet Committee Meeting when the draft report was first presented.

The CDA made a change to the runway rotation for the evening of Sunday, September 10th.  September 10 was the beginning of Test 3 Week 8, and the CDA planned to utilize the 4-22s for rotation.  The CDA was not able to use the 4-22s on Sept. 10 due to additional FAA technical operations work on the Runway 4R localizer. For the overnight hours, departures were on 9R and arrivals either on 10L or 10C. The FAA has indicated its work on the 4R localizer should affect our runway rotation only Sunday, and that we should be back on the 4-22s for the remainder of the week.

The O’Hare Noise Compatibility Commission met on Friday, September 8, 2017. The Commission was honored to welcome Dr. Alan H. Epstein, Vice President for Technology and Environment, Pratt & Whitney.

Dr. Epstein is responsible for setting the direction for and coordinating technology across the company. He leads Pratt & Whitney’s efforts to identify and evaluate new methods to improve engine performance and fuel efficiency. He also provides strategic leadership in the investment, development, and incorporation of technologies that reduce the environmental impact of Pratt & Whitney’s world-wide products and services.

The next ONCC meeting will be held on Friday, September 8, 2017 at Cafe la Cave (2777 S. Mannheim Road, Des Plaines, IL) @ 8 a.m.

At this meeting, the ONCC will hear from Dr. Alan H. Epstein, Vice President for Technology and Environment, Pratt & Whitney.

Fly Quiet Runway Rotation Test 2 Draft Report

  • Chicago Department of Aviation (CDA) staff gave a presentation on the draft report for Fly Quiet Runway Rotation Test 2. Highlights of the report included:
  • The average daily Fly Quiet start time was 10:41 p.m.; stop time was 5:44 a.m.
  • The average daily Rotation start time was 11:32 p.m.; stop time was 5:14 a.m.
  • Each runway at O’Hare is required by the FAA to be closed throughout the night for approximately one hour in order to perform a proper runway safety inspection for FAR Part 139. During this time, a configuration will stop and typically resumes after the safety inspection is complete.
  • The results of Test 2 show that 55 percent of the aircraft operations that occurred during the Fly Quiet Hours utilized the designated rotation runways. There was an average of 115 operations per night, 63 of which operated on designated runways. The remaining 45 percent of the operations were not on the designated runways due to reasons such as runway rubber removal, flight checks, wind conditions, weather or construction.
  • 1,606 survey responses submitted, which originated from 759 unique IP addresses.
  • Survey results show that 66.6% of the total survey responses believe that the Test should continue. Based on unique IP addresses received, 49.7% believe that the Test should continue.
    CDA staff will take comments on the draft report through Sept. 13. The final report will be presented to the Committee at their next meeting.

On August 24, 2017, ONCC members were invited to participate in a tour of the O'Hare Airfield. Members visited the new Northeast Cargo Ramp, Firefighter Training Area, viewed snow removal equipment, construction of new runway 9C/27C and construction of new gates at Terminal 3.

 

The CDA is publishing a slight change to the Runway Rotation Test schedule for Test 3 Week 5 (Week of August 20th). The FAA is working on a navigational aid called a localizer for Runway 9R-27L. 

For more information about a localizer, please visit the CDA website here

The only change to Week 5 is an added green arrow to depict a departure construction alternative, specifically departures on Runway 10L in the Secondary configuration. All versions of the Fly Quiet rotation scheduled have been updated posted to the CDA’s project website.
