Below are two scrollable PDF plots, one for KJFK Runway 4L departures impacting Malvern, and the other for KJFK Runway 22L arrivals using the infamous low-altitude ‘Arc of Doom’. Both plots were extracted from the recent noise study report done for FAA, by ESA, posted online at the airport authority PANYNJ website (report referenced in this article). Be sure to expand the view to see the finely detailed color-dots for these routes.

Generally speaking, repetitive noise impacts are more problematic the closer the flights are to the ground, but impacts tend to abate to a tolerable level at or above 8,000 feet altitude (blue dots on the Departure PDF, above).
Note also the extraordinary added distances being flown for these arrivals (see the light gray dots, at or above 6,000 altitude). Anyone who has been a passenger on a flight to KJFK has experienced the interminable arrival path that chugs along at low altitudes. This added work by ATC is created by too many flights, in too small an arrival window, forcing controllers to over-control the flights. The simplest solution, to reduce delays and noise and air pollutants, and to optimize efficiency, is for FAA to start managing capacity: setting and enforcing much lower hourly arrival rates and departure rates.
And What are PANYNJ Authorities Doing About It?
After years of complaints, Part 150 Studies were ordered for KJFK and KLGA. This formal process is designed to create an enormous volume of documents, many of which are almost indecipherable, to feed the illusion that citizens have an opportunity to aid in a decision-making process. In truth, it is all only for show; there is no meaningful or effective citizen involvement.
Here’s a challenge: go to this website (PANYNJ’s official webpage for the KJFK Part 150 Study) and spend a few minutes reading it and intuitively navigating. Try to learn from it, and see what valuable info/data you can find. More likely than not you will quickly leave your exploration, because PANYNJ, FAA and their well-paid pro-aviation consultant have created such an incredible volume of technobabble, and presented it in such a bizarre layout, that only the most obsessive individuals will press onward past the many click-deadends and long download times. I located some documents and spent well over an hour downloading the October 2016 ‘Draft Noise Exposure Map (NEM) Report’; 13 PDF files, measuring 1,349 pages (149Mb) total. Just finding and copying the documents is a substantial effort, and then to read all those pages? Do they really expect the average concerned citizen to do this much work??? Of course not.
If you liked that challenge, do it again at this website (same Part 150 page design, this time for KLGA!).
This appears to be what has evolved. Whether it is for a small and nearly dead airport in MN, AR, or wherever) or a huge chunk of airspace such as the LA Basin or the NYC area, FAA has evolved the public participation process (a requirement dating back to even before the 1946 Administrative Procedures Act) to make sure the average citizen is blown away with so much documentation (and much of it superfluous) that they simply give up even trying.
