Let’s replace the failed DNL metric; Submit Comments by March 15th

When it comes to mitigating (or even simply recognizing!) aviation noise, FAA has a proven track record of failure. This agency serves only industry, always working to enable more operations per hour at even the busiest airports. FAA consistently fails to properly assess noise impacts, and they persist in using the failed DNL noise metric designed to guarantees any and all expansion.

There is currently a solicitation for public comments. Please go to the Federal Register webpage and submit your comments, which might include:

  • Reject FAA’s use of the DNL noise metric, the 65 dB threshold, and continued use of the Schultz Curve.
  • Reject FAA’s desire to continue to research (and thus delay reforms).
  • Demand the use of noise metrics that already exist and actually work: a good choice might be simply quantifying the number of flights per hour in peak hours and the number of flights above (or audible) per day.
  • Demand widespread selective reversion of NextGen PBN procedures to reduce today’s impacts caused by repetition and route concentration; and,
  • Demand restored local controls (ability to limit traffic levels, impose curfews, etc.) and reassignment of federal ‘noise impact oversight’ from FAA to a restored ONAC-Aviation office at EPA.
