Fly Quiet Program

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 in an effort 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.

Runway Rotation Test

Test 1

The CDA submitted a Fly Quiet Runway Rotation Test (Test 1) to the Federal Aviation Administration (FAA) for approval of a six-month period. The purpose of the test was to evaluate a condition that could be in place until Runway 15/33 is permanently closed. Test 1 occurred during the overnight hours when demand required one arrival and one departure runway. Test 1 included a 25-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.

Test 2

The CDA submitted a second Fly Quiet Runway Rotation Test (Test 2) to the FAA for approval of a twelve-week test period. The purpose of the test was to:

1) Test the capabilities of the different configurations after responding to FAA concerns

2) Test new configurations that were not included in Test 1

Test 2 occured during the overnight hours when demand required one arrival and one departure runway. Test 2 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.

Test 3

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 occured 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.

Interim

The CDA submitted an Interim Fly Quiet Runway Rotation (IFQ) proposal to the FAA for approval of a temporary program that is intended to be implemented from soon after the requested FAA approval until Runway 9C-27C commissioning in late 2020. The IFQ reccomendation by the ONCC is the same runway configuration and sequence of configurations as was used in Test 3. It is expected that significant runway construction, maintenance, and/or pavement rehabilitiaion on Runways 4L-22R and 4R-22L will impact the IFQ during the 2019 and 2020 construction seasons, respectively.

The FAA is currently conducting a Written Re-Evaluation of the O'Hare Modernization Environmental Impact Statement for this Proposed Interim Fly Quiet Runway Rotation Plan.

The FAA is excepting public comments on the draft document from Monday January 14, 2019 through Wednesday, February 27, 2019.
