The ONCC Ad Hoc Fly Quiet Committee met for the fourth time on Monday, January 25, 2016 to review, discuss and recommend modifications for O’Hare’s nighttime noise abatement program to be presented to the FAA for review.

Three Fly Quiet Initiatives were presented: Refine Departure Procedures, Define Three Fly Quiet Programs (morning, evening and overnight) and Establish the overnight Rotation Plan. Discussion was primarily held on the first two initiatives. For the departure procedure discussion, Chicago Department of Aviation consultant Doug Goldberg from Landrum & Brown presented two refined departure heading charts and decision criteria. The first chart illustrated refined existing Fly Quiet departure tracks that were five miles in length. The second chart illustrated five additional departure tracks for runways 9R, 10L, 10C, 28R, and 28C. All 13 heading alternatives would be presented to the Federal Aviation Administration for review.

 

Other criteria included a recommendation for aircraft to utilize the full length of all runways during overnight hours and that all final procedure designs would be reviewed by ONCC prior to finalization and publication of the new Fly Quiet manual.

The committee unanimously voted to approve departure procedure decision criteria presented with the caveat that two additional departure headings recommended by the 41st ward would be included and voted upon in future meetings.

Decision criteria for the Three Fly Quiet Programs initiative also were discussed, but no votes were taken. The committee will meet again in February and prior to March 11 to discuss and vote on Fly Quiet Programs and rotation procedure options.
