CDA Submits Interim Fly Quiet Plan to FAA for Review
Based on the recommendation of the O’Hare Noise Compatibility Commission (ONCC), the Chicago Department of Aviation (CDA) submitted a proposal for an Interim Fly Quiet Runway Rotation Plan (IFQ) to the Federal Aviation Administration (FAA) for environmental review. The duration of the implementation of this proposal
is intended to occur from soon after the time of FAA approval until Runway 9C/27C is commissioned.

Technical Committee Summary—February 20, 2018
The O’Hare Noise Compatibility Commission Technical Committee met on Tuesday, February 20 at the Mount Prospect Village Hall. The Chicago Department of Aviation staff and consultants updated members on the Aircraft Noise Standards, permanent noise monitor installations, O’Hare Annual Operations, noise complaint system, 4th Quarter Fly Quiet Report and Interim Fly Quiet update.
ONCC to Host Panel on Departures
ONCC Leadership recently met with the O’Hare Control Tower to discuss departure turns. As a result of their discussion, the parties agreed to participate in an ONCC hosted panel discussion at the May 4, 2018 ONCC General Meeting meeting. 

ONCC Members are asked to submit questions for the panel discussion prior to the meeting in order to facilitate the meeting. Questions may be submitted to Jeanette Camacho.
City of Chicago Implements CAPTCHA Feature
The City of Chicago has implemented CAPTCHA, a new feature on its aircraft noise complaint website. This change is intended to prevent negative impacts to the City's 311 system for citywide service requests.

The process for residents to submit noise complaints will remain unchanged, except that they will be asked to click on a series of boxes indicating they are not a robot when submitting a noise complaint via the website.

ONCC will continue to provide input on improvements that should be made to the aircraft noise complaint system.
Study Shows Noise Annoyance Levels Have Shifted Over Time
A review of surveys of aircraft noise annoyance conducted between 2001 and 2014 in communities around 15 airports in Europe and Asia reached two major conclusions: 
  • Dose/response curves showing the percentage of people highly annoyed by aircraft noise have shifted over time, leading to a higher percentage of annoyed people at a given noise level compared to older surveys; and

  • This increase in the percentage of people highly annoyed by aircraft noise is greater at so-called "high-rate change" airports - those facing a sharp change in noise exposure due to activities, such as opening of new runways, operational changes, etc. - than at low-rate change airports.
