Chicago Mayor Richard M. Daley announced in June 1997 that O’Hare International and Midway airports agreed to use designated noise abatement flight procedures to further reduce the impact of aircraft noise at night.
The Fly Quiet Program provides pilots with operating procedures that observe nighttime flight tracks. The program’s voluntary guidelines were developed by the Chicago Department of Aviation (CDA) in cooperation with the O’Hare Noise Compatibility Commission, airlines and air traffic controllers.
The CDA distributes a Fly Quiet Manual to pilots and air traffic controllers that lists preferred runways and flight tracks to route aircraft over least populated areas during the hours of 10 pm to 7 a.m.
Adherence to the nighttime departure preferential flight tracks is measured by the Airport Noise Management System (ANMS). |
