Noise Metrics

MAC Noise Programs and Trends

Evolution of Noise Considerations

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.

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.

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

determine where aircraft

fly

Aircraft need to land and

takeoff into the wind

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.

WHO REGULATES AIRCRAFT NOISE

Federal Aviation Administration

Federal Aviation Regulation

Part 36

Regulates the maximum noise level a civil aircraft

can emit (Stage)

Aircraft Manufacturers

Air Traffic Control

FAA ATC controls every aircraft movement at MSP

and in the airspace around the metro

Aircraft Operators

Federal Aviation Regulation Part 150

Airport Noise Compatibility Planning

Airport

Airport Noise and Capacity

Act (1990)

No Access Restriction without Approval

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

All aircraft over 75,000 pounds must meet Stage 3 noise standards

by 2000

14 CFR Part 161 Published

Discriminatory access restrictions

are prohibited

MAC may not impose any

access restriction, such as curfews,

without FAA approval

Since 1990, FAA has not granted approval to any

airport

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.

2015 Actual Noise Contours

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

HOW IS DNL USED?

RESIDENTIAL NOISE MITIGATION

Ongoing Residential Noise Mitigation

• Beginning in 2016, residential units thathave been inside the 60+ DNL noisecontour, within a higher noise impactarea when compared to the previousprogram for 3 consecutive years will beeligible for additional mitigation

MAC NOISE PROGRAMS AND TRENDS

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.

MAC Staff use MACNOMS for complaint management and data validation.

NOISE MONITORINGMAC 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.

AIRCRAFT NOISE COMPLAINTSOnline 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 ReportCustomers 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

EVOLUTION OF NOISE CONSIDERATIONS

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

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

AIRCRAFT RESEARCH

Reduce aircraft fuel burn

Reduce nitrogen oxide (NOx) emissions

Reduce noise levels

Allow for sustainable alternative jet fuel

CLEEN – Continuous Lower Energy, Emissions, and Noise

NASA – Environmentally Responsible Aviation (ERA)

ERA’s mission was to explore anddocument the feasibility, benefits andtechnical risk of inventive vehicleconcepts and enabling technologies thatwould reduce aviation’s impact on theenvironment. Project researchers focusedon eight major integrated technologydemonstrations falling into threecategories – airframe technology,propulsion technology and vehiclesystems integration.
