1 2 nd Quarter 2016 Minneapolis-St. Paul International Airport (MSP) Public Input Meeting Metropolitan Airports Commission Noise Program Office April 27, 2016

2 PUBLIC INPUT MEETING Meeting Goals To hear the views and concerns of citizens in communities around MSP regarding aircraft noise To promote greater citizen input and feedback on MAC plans and initiatives To disseminate information to the public To promote and assist in greater citizen awareness of MAC Noise Program Office plans and initiatives

3 PUBLIC INPUT MEETING OUTLINE MAC Presentation Air Transportation Agencies Noise Metrics MAC Noise Programs and Trends Evolution of Noise Considerations

4 AIR TRANSPORTATION AGENCIES

5 AIR TRANSPORTATION AGENCIES Airlines Transport people and products domestically and internationally Federal Aviation Administration Regulates Airports Regulates Airlines Operates Air Traffic Control Facilities Metropolitan Airports Commission Owns and Operates MSP and 6 Reliever Airports Provides a Facility for Airlines to Conduct Air Commerce Activities

6 AIR TRANSPORTATION AGENCIES Airlines Transport people and products domestically and internationally Airlines determine Number of Flights Aircraft Types Flight Times These decisions are dictated by scheduling designed to meet customer travel preferences. The number of flights, types of aircraft and flight times are driven by passenger demand MSP does not have a mandatory curfew. The MAC does not have the authority to create one.

7 AIR TRANSPORTATION AGENCIES Federal Aviation Administration Regulates Airports Regulates Airlines Operates Air Traffic Control Facilities The FAA dictates airspace and runway use based on Safety Efficiency Wind direction and wind speed Air traffic demand Aircraft weight Capacity Noise abatement The MAC does not Aircraft need to land and takeoff into the wind determine where aircraft fly

8 AIR TRANSPORTATION AGENCIES Metropolitan Airports Commission Owns and Operates MSP and 6 Reliever Airports Provides a Facility for Airlines to Conduct Air Commerce Activities Airport authorities facilitate safe and efficient operations of the airport by maintaining facilities (runways, terminals, parking structures, etc.) Airports manage noise programs through residential noise mitigation, land use planning, and by operating noise and operations monitoring systems. Airports are required to use the Day-Night Average Sound Level (DNL) metric to assess aircraft noise impacts for noise mitigation and land use planning.

9 NOISE METRICS

10 NOISE UNPLEASANT OR UNWANTED SOUND

11 SOUND LEVELS OF TYPICAL NOISE SOURCES

12 WHO REGULATES AIRCRAFT NOISE Federal Aviation Administration Federal Aviation Regulation Part 36 Air Traffic Control Federal Aviation Regulation Part 150 Airport Noise and Capacity Act (1990) Regulates the maximum noise level a civil aircraft can emit (Stage) FAA ATC controls every aircraft movement at MSP and in the airspace around the metro Airport Noise Compatibility Planning No Access Restriction without Approval Aircraft Manufacturers Aircraft Operators Airport Airport

13 AIRPORT NOISE AND CAPACITY ACT (1990) Aviation Noise Management is critical Past local noise concerns led to inconsistent restrictions on aviation Noise must be addressed at a national level All aircraft over 75,000 pounds must meet Stage 3 noise standards by 2000 Since 1990, FAA has not granted approval to any airport MAC may not impose any access restriction, such as curfews, without FAA approval Discriminatory access restrictions are prohibited 14 CFR Part 161 Published

14 DNL DNL (Day-Night Average Sound Level) is the FAA-mandated metric for assessing aircraft noise impacts around U.S. airports. The DNL metric is used to determine eligibility in Residential Noise Mitigation programs per the FAA. DNL is a daily average of aircraft noise events levels with a 10dB penalty applied to nighttime flights between 10:00 PM and 7:00 AM. This 10dB penalty is the equivalent to counting one nighttime flight as 10 flights. Amplitude Number of Events Time Aircraft = Distance Between 10pm and 7am

15 TYPICAL OUTDOOR COMMUNITY DAY-NIGHT AVERAGE SOUND LEVELS

16 HOW IS DNL USED? MSP Flight Track data are used in the FAA noise model to produce Noise Contours Noise Contours depict noise exposure from aircraft operations 2015 Actual Noise Contours Recorded noise events from the MAC s Remote Monitoring Towers are not used to produce noise contours

17 RESIDENTIAL NOISE MITIGATION Ongoing Residential Noise Mitigation Beginning in 2016, residential units that have been inside the 60+ DNL noise contour, within a higher noise impact area when compared to the previous program for 3 consecutive years will be eligible for additional mitigation

18 MAC NOISE PROGRAMS AND TRENDS

19 MACNOMS The MAC Noise and Operations Monitoring System collects and correlates noise and flight-track data and is the source data for the website. External users can use the macnoise.com website to launch Flight Tracker and/or to see monthly or annual noise reports. MAC Staff use MACNOMS for complaint management and data validation. Reports MACNOMS website MAC Staff Internet Users

20 NOISE MONITORING MAC operates 39 permanent Remote Monitoring Towers (RMTs) in the surrounding communities. Data are recorded, downloaded, validated, and noise events are correlated with flight-track data to determine if the event was an aircraft or community noise event. Noise monitoring equipment is calibrated and certified at an independent accredited laboratory on an annual basis. Recorded noise events from the MAC s Remote Monitoring Towers are not used to produce noise contours.

21 AIRCRAFT NOISE COMPLAINTS Online Complaints Customers enter time and location information directly through MAC Noise website Phone Complaints Customers leave voice messages and staff enters complaint information Complaints are used in conjunction with flight track data to corroborate specific events or to identify possible operational trends Customers who request a call back will receive one within 3 business days Complaints are reported in the monthly Technical Advisor s Report The FAA Air Traffic Control Tower does not consider aircraft noise complaints when making runway use and flight direction decisions

22 MSP NOISE OVERSIGHT COMMITTEE (NOC) Community Representatives Minneapolis Richfield Bloomington Eagan Mendota Heights At-Large Representative Apple Valley, Burnsville, Edina, Inver Grove Heights, St. Paul, St. Louis Park and Sunfish Lake Industry Representatives Scheduled Airlines Cargo Carrier Charter Operator Chief Pilot Minnesota Business Aviation Association At-Large Representative NOC brings policy recommendations regarding aircraft noise issues to the MAC Board NOC viewed as an industry model in reaching collaborative solutions to aircraft noise impacts

23 MSP RUNWAY CONFIGURATIONS South Flow Configuration Southern / Eastern winds More prevalent in the late Spring to Early Autumn North Flow Configuration Northern / Western winds More prevalent in Late Autumn to Early Spring

24 MSP WIND CONDITIONS January February 2016 March April 26, 2016

25 MSP RUNWAY USE January February 2016 March April 26, 2016

26 EVOLUTION OF NOISE CONSIDERATIONS

27 NOISE METRICS FAA studying the DNL Metric Polling residents near 20 airports nationwide Data collection scheduled to continue until the end of 2016 The FAA will then analyze the results to determine whether to update its methods for determining exposure to aircraft noise If changes are warranted, the FAA will propose revised policy and related guidance and regulations, subject to interagency coordination, as well as public review and comment

28 ST. LOUIS PARK CITY RESOLUTION St. Louis Park City Council Passed a resolution on January 19, 2016 Urges the FAA to recognize the impacts of aircraft noise beyond DNL 65 decibel threshold. Urges the FAA to use alternative noise metrics when evaluating noise impacts from new PBN flight procedures

29 AIRCRAFT RESEARCH CLEEN Continuous Lower Energy, Emissions, and Noise Reduce aircraft fuel burn Reduce nitrogen oxide (NOx) emissions Reduce noise levels Allow for sustainable alternative jet fuel NASA Environmentally Responsible Aviation (ERA) ERA s mission was to explore and document the feasibility, benefits and technical risk of inventive vehicle concepts and enabling technologies that would reduce aviation s impact on the environment. Project researchers focused on eight major integrated technology demonstrations falling into three categories airframe technology, propulsion technology and vehicle systems integration.
