Item 3: Update on the FAA’s Survey to Re-Evaluate Noise Measurement Methods

On May 7, 2015 the FAA announced it would begin evaluating its methods for measuring aircraft noise. This is a multi-year process, which the FAA began in mid-2015 with a survey of public perceptions of aircraft noise. The survey will take place for a year’s time in communities situated around 20 airports nationwide. The FAA is not disclosing the airport communities in which it will conduct the survey. According to the FAA, the results will be used to determine whether an update to FAA policies regarding the Day-Night Average Sound Level (DNL) metric is warranted, along with the parameters under which a home is eligible to receive federal funding for mitigation (65 decibel DNL).

Item 3: Update on the FAA’s Survey to Re-Evaluate Noise Measurement Methods

Viewing this as an opportune time to address the FAA about noise impacts beyond the 65 decibel DNL noise level, on January 19, 2016 the City of St. Louis Park passed a city resolution titled: Resolution Regarding Federal Aviation Administration Recognition of Aircraft Noise Impacts outside the Day-Night Average Sound Level (DNL) 65 Decibel Threshold. The Resolution is to be delivered by the City of St. Louis Park to the FAA administration in Washington DC.

Item 4: MSP Converging Runway Operations Presentation: Elaine Buckner, MSP Air Traffic Manager

Noise Oversight Committee January 20, 2016

The 2016 NOC Work Plan includes a trend analysis in wind and the relationship to aircraft noise complaints.

Item 5: Wind and Aircraft Noise Complaint Trend Analysis

FAA’s runway use decisions are often predicated on the direction and speed of the wind as aircraft need to land and takeoff into the wind. At MSP, winds in the summer are generally from the south and southeast with warmer temperatures, while autumn and winter trends favor winds from the north and northwest. However, autumn and winter of 2015 produced higher than average temperatures and more south and southeast winds than previous years.

Item 5: Wind and Aircraft Noise Complaint Trend Analysis

Sept-Dec 2014 Sept – Dec 2015

Source: Iowa Environmental Mesonet (IEM)

In 2014 temperatures in autumn and winter were slightly below normal, while the temperatures in 2015 were 4°C (7.2°F) above normal.

With south flow configurations lasting longer into the 3rd and 4th quarters of 2015, areas to the northwest experienced more arrival flights than previous years, while areas to the south and southeast saw an increase in departure traffic. South Flow (S) Straight South Flow (S*)

Although some areas did see more aircraft traffic, the overall number of operations at MSP are down from 2014. While overall aircraft operations are down, nighttime

• perations have increased.

The FAA’s continuous use of south flow operations and increased nighttime flights have contributed to increased noise complaints.

Item 6: Airbus Aircraft Vortex Generators

The 2016 NOC Work Plan includes an investigation into the noise reduction benefits of Vortex Generators on Airbus A320 aircraft.

Item 6: Airbus Aircraft Vortex Generators Airbus A320 Family of aircraft: A321 A320 A319 A318

During approach, the A320 family of aircraft emit a high- pitched sound:

• Due to air flowing across vent openings under the wings
• Perceived on the ground over 6 miles from the runway, as

the aircraft is approaching for landing, prior to landing gear and flap extension

Item 6: Airbus Aircraft Vortex Generators

Vortex generator:

• Small triangular piece of aluminum sheet metal that is

mounted upstream of air holes or vents on each wing

• Reported to eliminate high pitched tones
• Designed by German Aerospace Center (DLR)
• Lufthansa reports an overall noise reduction up to 4.4 dB
• All new Airbus aircraft delivered after 2014 will have these

devices installed before delivery

• Lufthansa and AirFrance have started installing vortex

generators on their fleet of A320s

Noise levels were recorded at six monitoring points near Frankfurt Airport. Vortex generators provided:

• 0.2 dB reduction up to 6 miles from the airport
• 1.5 dB to 2.5 dB reduction from 6 to 9 miles from the

airport

• 3.0 dB up to 4.4 dB reduction over 9 miles from the

airport
