Presenter(s): Arlyn Purcell, Director, Aviation Environment and Sustainability; Stan Shepherd,
Manager, Aviation Noise Programs; David Suomi, FAA Deputy Regional Administrator; and Steve
Karnes, FAA Senior Technical Advisor. 
The Commission received a presentation covering the Port's noiseinformation and mitigation
programs, recent trends in aircraft operations and economic impacts, and introductory information
on flight procedures and flight tracks. Recommended programs approved as part of the Port's 2014
Part 150 study were summarized. 
Commissioners requested clarification on Port efforts to make homeowners aware of available
noise insulation opportunities under the Part 150 process. Commissioners asked about the extent
of nighttime aircraft noise impacts. Jet noise abatement procedures that affect the approach areas
for aircraft were described. Commissioners requested a better depiction of the neighborhoods that 
correspond to the flight paths of the jet noise abatement program. 
Commissioners asked for clarification about how the Port's noise model is weighted for a variety of
factors such as altitude, type of aircraft, number of aircraft, direction of flight, weather conditions,
flights at night, etc. The portion of aircraft final approaches that accord with NextGen procedures
and those that accord with conventional descent procedures were presented. Commissioners
commented on the more rapid rise in passenger numbers than in aircraft operations due to use of
larger planes and more fully loaded flights. 
Mr. Suomi and Mr. Karnes presented the Federal Aviation Administration's NextGen system
portfolio as a set of improvements to better and more efficiently assist aircraft navigation, improve
communication, and achieve better surveillance of aircraft, with safety being the FAA's primary
objective. Commissioners asked for an explanation of how NextGen helps avoid airline delays.
Optimized flight descent was described, including the narrowing of the flight path.

Commissioners asked about the length of time flight data is kept by the FAA and how it is
summarized on a periodic basis. There was a discussion of whether elements of NextGen might
further reduce emissions and noise impacts given an overall increase in air traffic in the system.
Safety and system redundancy were discussed. 
Commissioners commented on improved proactive communication by the FAA as a way of
reducing  community  anxiety  about  increased  air  traffic  and  changing  traffic  patterns.
Commissioners asked about options for expanding the noise mitigation boundary. It was explained
that the Day-Night-Level (DNL) noise measurement of 65 DNL is established federally by statute.
Intensity of noise impact in a smaller area was discussed. Commissioners asked for better
advance information from the FAA when flight patterns change. 
Commissioners asked about how long it would take to implement NextGen throughout the national
aviation system. Commissioners requested clarification on the relationship of NextGen and tree
removal and replacement associated with the Flight Corridor Safety Program. It was reported that
tree removal is not a NextGen requirement per se, but is related to other regulatory requirements of
the FAA covering flight corridor obstructions. 
Mr. Suomi and Mr. Karnes were invited to remain to hear public testimony on Airport noise-related
matters, but explained they were unable to do so. 
A recording of this part of the meeting has been made available online. 
The unanimous consent agenda was considered previously, and the Commission advanced to
