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 Meeting Goals To disseminate information to the public To promote and assist in greater citizen awareness of MAC Noise Program Office plans and initiatives
PUBLIC INPUT MEETING OUTLINE MAC Presentation Air Transportation Agencies Noise Metrics MAC Noise Program Aircraft Noise Updates NOC Updates
AIR TRANSPORTATION AGENCIES
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
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. MSP does not have a mandatory curfew. The MAC does not have the authority to create one. The number of flights, types of aircraft and flight times are driven by passenger demand
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 Aircraft need to land and takeoff into the wind The MAC does not determine where aircraft fly
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 are required to use the Day-Night Average Sound Level (DNL) metric to assess aircraft noise impacts for noise mitigation and land use planning. Airports manage noise programs through residential noise mitigation, land use
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
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 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 All aircraft over 75,000 pounds must meet Stage 3 noise standards by 2000
NOISE METRICS
NOISE UNPLEASANT OR UNWANTED SOUND
SOUND MECHANICAL VIBRATION TRANSMITTED THROUGH A MEDIUM
DNL DAY NIGHT AVERAGE SOUND LEVEL FAA-mandated metric for assessing aircraft noise impacts around U.S. airports. DNL metric is used to determine eligibility in Residential Noise Mitigation programs per the FAA. DNL is a daily average of aircraft sound events levels 10dB penalty applied to nighttime flights between 10:00 PM and 7:00 AM. Distance Amplitude Number of Events Time Aircraft = Between 10pm and 7am
TYPICAL OUTDOOR COMMUNITY DAY-NIGHT AVERAGE SOUND LEVELS
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 Recorded noise events from the MAC s Remote Monitoring Towers are not used to produce noise contours
RESIDENTIAL NOISE MITIGATION Ongoing Residential Noise Mitigation 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 Mitigation activities will begin in 2017 Homeowners that are eligible were sent initial letters in June For eligibility questions please visit: https://msp.macenvironment.org/mitigati on
MAC NOISE PROGRAM
MACNOMS The MAC Noise and Operations Monitoring System collects and correlates noise and flight-track data and is the source data for the www.macnoise.com website. External users can use the macnoise.com website to launch Flight Tracker and/or to see monthly or annual noise reports. Reports MACNOMS MAC Staff MAC Staff use MACNOMS for complaint management and data validation. website www.macnoise.com Internet Users
SOUND MONITORING MAC operates 39 permanent Remote Monitoring Towers (RMTs) Sound events are recorded, validated, and correlated with flight-track data to determine if the event was an aircraft or community noise event. Sound monitoring equipment is calibrated and certified at an independent accredited laboratory on an annual basis. Recorded sound events from the MAC s Remote Monitoring Towers are not used to produce noise contours.
AIRCRAFT NOISE COMPLAINTS Customers who request a call back will receive one within 3 business days The FAA Air Traffic Control Tower does not consider aircraft noise complaints when making runway use and flight direction decisions 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 Complaints are reported in the monthly Technical Advisor s Report
MSP NOISE OVERSIGHT COMMITTEE (NOC) 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 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
AIRCRAFT NOISE UPDATES
DNL METRIC FAA is 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
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. Eight major integrated technology demonstrations falling into three categories Airframe technology Propulsion technology Vehicle systems integration.
