Hi! My name is Jim Allerdice. I’m the Managing Partner and Chief Consultant for Terminal Operations, for ABCx2, LLC. ABCx2 is a community focused company that provides advocacy for communities with the FAA, Airports, and the Aviation Industry at large. We provide a voice for communities and interpret the technical language of the aviation industry in such a way as to provide meaningful, measurable and implementable solutions for communities impacted by aviation noise. What is dispersion?  The process of introducing track variability by changing aircraft lateral position enough to spread out repetitive and intrusive noise events experienced by people living under highly concentrated flight paths. Presenter Presentation Notes Today, I want to talk to you about dispersion. Many communities believe that noise dispersion holds the answers to the impacts felt from aircraft operations. But first, we must find a definition of dispersion. What does dispersion look like in the age of RNAV? Well, for our purposes today, dispersion is… So, how do we get to dispersion? First, we must understand why the FAA likes Performance Based Navigation, or PBN, so much. What types of dispersion exist?  Natural (or random)  Associated with manually flown conventional procedures and ATC vectors  Systematic  Aircraft use alternative flight paths with very precise and predictable trajectories but in a controlled manner  This type of dispersion is most associated with the use of satellite- based navigation capabilities  Examples  Radar Vectors to RNAV  Open SIDs  Additional departure tracks…
