Airport Noise Management System
Reports Provide Vital Monthly Data

The Airport Noise Management System (ANMS) collects, analyzes and processes data from several sources including
32 noise monitors around
O’Hare, FAA radar data, weather data and noise complaints.
The City of Chicago and ONCC use this monthly data report to facilitate development and management of noise abate-
ment programs at O’Hare.

Data from Permanent Noise Monitors and/or
Long-term Portable Monitors does not determine eligibility for residential or school sound insulation.

September 2014 ANMS Report
Most used departure runway: 28R – 54%; most used arrival runway: 27L – 38%; residents from 10 addresses reported 32,532 complaints for all hours read more


Fly Quiet Nighttime Program Reports

The Fly Quiet Program is voluntary at O’Hare International Airport. It encourages use of designated nighttime preferential runways and flight tracks developed by the Chicago Department of Aviation in cooperation with ONCC, the airlines, pilots and air traffic controllers.

Preferred routes direct aircraft over less-populated areas such as forest preserves, highways, and commercial and industrial areas during the hours of 10 p.m. to 7 a.m.
