  • CDA Briefs Technical Committee on Fly Quiet Rotation Plan

    April 19, 2016

    The Chicago Department of Aviation briefed the ONCC Technical Committee on a six-month Fly Quiet Rotation Plan test during the April 19 meeting. The nighttime rotation plan, calls for 12 one-week periods that incorporate parallel and diagonal runways and six east flow and six west flow configurations.

    Before the presentation, ONCC Chair and Mount Prospect Mayor Arlene A. Juracek reminded the members that it was “important to do our homework” and engage in dialog, analyze the viewpoints and take a “regional approach” to mitigate aircraft noise.

    The Commission is looking for a two thirds majority vote to change the status quo and pass the Fly Quiet rotation plan at its May 6 meeting. Once passed, the plan can be submitted with the “confidence of community consensus” to the Federal Aviation Administration for implementation by June or July.
