National Environmental Policy Act of 1969 (NEPA) - Correct answer-catalyst for public
awareness and response to aircraft noise issues, required
... [Show More] assessment of noise effects
for airports undertaking major projects
Aviation Noise Abatement Policy (ANAP) - Correct answer-Secretary of Transportation
and FAA adopted. clarified FAAs responsibility to reduce aircraft noise, abate the impact
of noise on populated areas and attain compatible land use adjacent to airports
FAR Part 36-Certificated Airplane Noise Levels - Correct answer-mandated change in
design inturbojets to help eliminate engine noise,Stages 1-4 with 4 being quietest,
aircraft over 12,500# must meet Stage 4
Airport Safety and Noise Abatement Act of 1979 (ASNA) - Correct answer-basis for
noise abatement planning at airports, required FAA to establish requirements to simplify
and standardize noise compatibility planning and programs
Part 150 Land Use Compatability - Correct answer-adopted as a result of ASNA, noise
control achieved through compatible land uses around airport, developed Noise
Exposure Maps (NEM) & Noise Compatibilty Programs (NCP)
Airport Noise and Compatibility Act of 1990 (ANCA) - Correct answer-airports prohibited
from adopting overly restrictive or punitive anti-noise ordinances, created Part 161
Notice and Approval of Airport Noise and Access Restrictions-placed a cap on number
of Stage 2 aircraft over 75,000lbs maximum takeoff weight allowed to operate in the US
3 Goals of ANCA - Correct answer-1. phase out noisier aircraft
2. place limits on local user restrictions
3. establish non-restrictive noise abatement and land use actions
Day/Night Average (DNL) - Correct answer-standard used for forecasting cumulative
noise exposure under Part 150 studies, a 24-hour average sound level, with 10 decibel
penalty from midnight to 7am and 10pm to midnight, noise is averaged every second
over a 24hour period
Integrated Noise Model (INM) - Correct answer-determines DNL noise contours area for
a specific mix of aircraft and produces maps used for land compatibility
Aviation Environmental Design Tool (AEDT) - Correct answer-replced INM, software
that models aircraft fuel consumption, emissions, noise, and air quality consequences
75 DNL - Correct answer-FAA recommends airport own all land within the 75 DNL
contour
65 DNL - Correct answer-Part 150 all land uses are compatible under 65 DNL
Airport Influence Area or Public Airport Disclosure Maps - Correct answer-reveal
potential noise impacted areas to boards and planning commissions
Air Traffic Noise Screening (ATNS) - Correct answer-computer program that assists
determing if a change in arrivals and departures will increase noise
Categorically Excluded - Correct answer-changes above 3,000' are excluded
FAR Part 150 Process - Correct answer-Airport sponsor can implement a noise
mitigation program. Federal funding may be available. Sponsor is required to base
program on Noise Exposure Map (NEM) and Noise Compatibility Program (NCP)
Airport and Airway Improvement Program (AAIP) - Correct answer-approved Noise [Show Less]
