The ONCC Ad Hoc Fly Quiet Committee met on August 30, 2017.


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.

Fly Quiet Runway Rotation Test 3 – Weekly Report Overview

The committee also reviewed the weekly reports of Weeks 1 – 4 for Fly Quiet Runway Rotation Test 3, which started the week of July 23. Several committee members shared their communities’ experience with Test 3.

During the Test 3 discussion, CDA staff mentioned that it was time to begin thinking about a possible Runway Rotation plan for the interim period (Spring 2018 – Fall 2020). Committee Chair Joseph Annunzio of Niles reminded the committee that Test 3 is not set in stone. The Committee’s goal is to determine the best approach for Fly Quiet during the interim period.

CDA staff reminded the Committee how important feedback from residents will be in developing options for the interim Fly Quiet period. Residents are encouraged to visit and complete the survey on Test 3. They also mentioned that it is important to also consider what a Final Fly Quiet plan will look like once the OMP is completed in 2020.

The committee is expected to reconvene in approximately 3 weeks (date TBD) to review the final report on Test 2, and begin discussion on options for an interim Fly Quiet plan.
