Airport Noise Management
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.
August 2014 ANMS Report
Most used departure runway: 28R – 40%; most used arrival runway: 27L – 26%; noise complainants (all hours) 4,024 residents; (44% of 30,249 August calls came from 11 addresses) 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.
