Airport Noise Compatibility Study Group New Technologies Committee Noise Abatement Measures and Criteria  Committee priorities and screening assessment compared  acknowledge disconnects discussed in other committees  sound assessment of technology requires hard data and analysis  focus on measures of specific interest to the committee  Advanced technology  need means to evaluate effects of hardware, not just procedures  if hardware not developed enough for evaluation, document ‘state of the art’ for further study

Airport Noise Compatibility Study Group New Technologies Committee Noise Abatement Measures  Navigation aids  variety of alternatives, hard to dictate specifics to users  consider common standard instead, e.g. “RNP” (required navigational performance)  bottom line: tighten flight tracks to within ±X, with X as small a standard as can be adopted  Airport facilities  most measures deferred to mitigation assessment  runway extension/overrun: evaluate as preexisting

Airport Noise Compatibility Study Group New Technologies Committee Noise Abatement Strategies  “Further analysis” of advanced technology hard to discern  screening assessment lacks specifics  strategies combine multiple measures  discrimination of individual effects not pre-designed  Knowledge base resulting from study of technology- based measures may be at least as important as model results

Airport Noise Compatibility Study Group New Technologies Committee Noise Mitigation Screening Criteria  Suggested criteria adequate  consistent with study goals  reduce/prevent non-compatible land use  provide noticeable noise reduction  consistent with local policies  feasible  Refinements  distinguish between 2d, 3d  noise reduction is quantitative - support evaluation with hard data  “feasible” must specify  technically  economically

Airport Noise Compatibility Study Group New Technologies Committee Noise Mitigation Measures Measures adequate; focus on knowledge base, implementation  Document available knowledge on measures assessed, whether adopted or not  remedial measures  compensatory measures  preventive measures  Impose systematic process on any on-site mitigation project  measure existing noise reduction  design/specify mitigation standards  re-examine facility; adjust as required  certify attainment of standards  qualified management and oversight
