On June 17, 1997, the City of Chicago announced that airlines operating at Chicago O'Hare International Airport (O'Hare) had agreed to use designated noise abatement flight procedures in accordance with the Fly Quiet Program. This program was implemented to reduce the impacts of aircraft noise on neighborhoods surrounding O'Hare. The Fly Quiet Program is a voluntary program that encourages pilots and air traffic controllers to use designated nighttime preferential runways and flight tracks developed by the Chicago Department of Aviation (CDA) in cooperation with the
O'Hare Noise Compatibility Commission (ONCC), the airlines, and the air traffic controllers. These preferred routes are intended to direct aircraft over less-populated areas, such as forest preserves and highways, as well as commercial and industrial areas.

The CDA fact sheets are formatted for double-sided printing on the short edge of 11x17 paper.
The Fly Quiet Recognition Awards were developed by the ONCC with the intention to reward airlines that comply with O’Hare’s voluntary Fly Quiet Program. Awards are given every year in three categories; air carrier, regional air carrier, and cargo carrier, to the top scoring airlines that had at least one average nightly operation.

The FAA conducted an environmental analysis called the Written Re-Evaluation of the O'Hare Modernization Environmental Impact Statement for the Interim Fly Quiet Runway Rotation Plan. The CDA's submittal and the subsequent FAA approval can be found below.

The CDA submitted a third Fly Quiet Runway Rotation Test (Test 3) to the FAA for approval of a twelve-week test period. The purpose of the test was to test a condition that could be in place during the period of time between Runway 15-33 decommissioning until Runway 9C-27C commissioning. Test 3 occurred during the overnight hours when demand required one arrival and one departure runway. Test 3 included a 12-week schedule that consisted of 12 weekly periods intended to balance the overnight noise. Each new week began on Sunday evening at 10 p.m. or after when demand allowed for one arrival and one departure runway.
