Welcome to

CJSC, LLC


We support communities advocating for aviation noise and air pollution reduction.


About us



What we do:

  • Explain the FAA's noise and land use compatibility planning process (14 CFR Part 150) and what this process can and cannot do to reduce noise impacts
  • Demystify the FAA's noise and air pollution modeling methods
  • Explain the environmental compliance processes for airport development and flight path changes and what these processes can and cannot do to reduce noise and air pollution impacts
  • Review noise roundtable structures and work programs, then propose refinements to increase advocating power

Our experience includes:

  • Co-managing the development of the Aviation Environmental Design Tool (AEDT), the FAA's required noise and air pollution model
  • Co-managing the development of the Aviation Emissions and Air Quality Handbook version 3, used nationwide for aviation air pollution compliance
  • Serving as flight path environmental expert and backup facilitator for the LAX/Community Noise Roundtable and the Santa Clara/Santa Cruise Roundtable
  • Serving Project Director and Deputy Director roles for the JFK and LaGuardia noise studies, two of the largest such studies in aviation history
  • Supporting environmental compliance activities for airport and flight path projects at over a dozen airports across the United States
