Navigation Committee NOISE ABATEMENT STRATEGY Findings and Recommendations Meeting 5A October 18, 2001 Airport Noise Compatibility Study Group
FORECAST 1997 CONDITIONS, VERSUS ACTUAL 1998 CONDITIONS an object lesson Area the previous noise program was approved to leave above Federal noise standards by 1997. Area actually exceeding Federal noise standards in 1998, as measured in the current noise study.
FLIGHT TRACKS four days of arrivals from the north
FORECAST 1997 CONDITIONS, VERSUS ACTUAL 1998 CONDITIONS an object lesson no easy cure... Area the previous noise program was approved to leave above Federal noise standards by 1997. DNL 60 contour estimated for perspective. Area actually exceeding Federal noise standards in 1998, as measured in the current noise study. DNL 60 contour added for perspective.
FORECAST 1997 CONDITIONS, VERSUS ACTUAL 1998 CONDITIONS an object lesson very large contours focus of current mitigation Area the previous noise program was approved to leave above Federal noise standards by 1997. DNL 60 contour estimated for perspective. Area actually exceeding Federal noise standards in 1998, as measured in the current noise study. DNL 60 contour added for perspective.
FLIGHT TRACKS four days of departures to the south
Navigation Committee • OBSERVATIONS • potential reduction of non-compatible land use is dramatic • with Alternative 3 in the north • with common measures alone (Alternative1) in the south • but - what else can we do? • action beyond the contours • mitigation • oversight, and enhancement - make this a living program Airport Noise Compatibility Study Group
Navigation Committee • NEXT STEPS • flight track management to depth of Louisville airspace • enhanced standard arrival and departure specs • evaluate prospects for ‘reverse flow’ at selected times • displaced arrival thresholds • noise abatement flight procedures • … etc. And then there’s mitigation, implementation, and documentation. • Much work remains. Let’s get to it! Airport Noise Compatibility Study Group
