New Business

Runway rotation
CDA consultants reviewed Runway Rotation models. Bensenville presented a runway rotation option. 

There were concerns about converging runways and taxiway ground traffic.

CDA consultants presented an overview of the runways, length, usage and potential predictability. It was explained that many factors lead to runway usage – can vary depending on the airline, weather conditions, environment on the ground (construction, maintenance), aircraft, weight, destination, origin, want vs need.

It was suggested that the committee obtain feedback from pilot representative/s to determine what is feasible from their perspective.

Case studies
CDA consultants reviewed preferential runway usage, departure procedures, land use and population examples from other airports.

The next Fly Quiet Committee meeting is scheduled for October 18, 2018 at the Chicago Department of Aviation.
