The Chicago Department of Aviation (CDA) has submitted a Fly Quiet 21 Plan (FQ21) to the Federal Aviation Administration (FAA) for nighttime operations at Chicago O’Hare (ORD) Airport. The FQ21 Plan is a voluntary program that aims to balance nighttime noise impacts by alternating among different runway configurations based on wind conditions. The FAA is currently working with the CDA to analyze the environmental impacts of the FQ21 plan submitted to the FAA.
