National Academy of Sciences study, framework, and diagnostic tool

(a) In general The Administrator shall enter into a contract with the National Academy of Sciences to conduct a study that— (1) summarizes the relevant literature and studies done on aviation impacts worldwide; and (2) focuses on large hub commercial airports and surrounding communities, including communities currently outside of the 65 DNL contour in— (A) King County, WA; (B) Boston; (C) Chicago; (D) New York City; (E) the Northern California Metroplex; (F) Phoenix; (G) the Southern California Metroplex; (H) the District of Columbia; (I) Atlanta; and (J) any other metropolitan large hub airport identified by the Administrator. (b) Contents The study described in subsection (a) shall examine— (1) the collection and consolidation of quantifiable, observational, experiential, anecdotal, or other data from— (A) the Federal Aviation Administration; (B) airport operators; (C) valid acoustic instrumentation on the ground; (D) testimonials and other evidence from community members; and (E) organizations in the community; (2) the Day-Night Average Sound Level, using measured data or modeled data (or other noise metrics, as applicable); (3) any other existing or supplemental noise metrics from data collected by noise monitor stations; (4) emissions generated by individual and cumulative takeoffs and landings, including emissions that impact the ground level; (5) lateral trajectory and altitude of flight paths as demonstrated by actual and comprehensive radar flight track data in addition to published routes; (6) how aviation impacts communities surrounded by multiple airports; (7) how aviation impacts communities with unique geography, including communities situated at higher elevation or near large bodies of water; (8) any other data requested by the impacted community in order to give a comprehensive understanding of the impacts on such community, including comparative data for equity analysis; (9) recommendations on actions or mitigation that can be taken to alleviate— (A) concerns raised during community outreach; and (B) effects that are determined in the study; and (10) any other data or information determined to be relevant by the National Academies in analyzing aviation impacts. (c) Framework and diagnostic tool (1) In general Using findings from the study, the National Academy of Sciences shall provide the FAA with a framework and diagnostic tool for— (A) conducting appropriate community assessments upon request of community boards (including as described in section 5(f)); (B) measuring the impact on communities of— (i) high frequency of overhead flights; (ii) an increase or change in flight operations due to adoption of new flight procedures; (iii) high frequency or an increase in night time aircraft noise; and (iv) decreased dispersion of flight path utilization; and (C) developing a scientifically based strategy for evaluating structures subject to increases described in subparagraph (A)(ii) that should be eligible for noise mitigation. (2) Requirement In developing the framework and diagnostic tool under paragraph (1), the National Academy of Sciences shall— (A) seek appropriate community input and feedback from community boards as well as open community meetings; and (B) ensure, to the extent practicable, that such framework and diagnostic tool is understandable to, and useable by, the community boards and the general public.
