NEW BUSINESS
Next Generation and Stage V Updates
Assistant City Administrator Miller noted this is a standing agenda item to provide an opportunity to
anyone on the Commission who may have updates or information to share regarding Next Generation
Aviation and/or Stage V aircraft.
Commissioner Johnson noted he recently received a presentation from the FAA out of recent Next Gen
update in Washington and will distribute it to the group and the Commission can decide if there are
slides that are appropriate for the community.
2017 Actual Annual Noise Contours
Assistant City Administrator Miller noted the 2017 Metropolitan Airport Commission Actual Noise
Contours have been released and show there has been an impact to Eagan. Per the requirement of the
2007 consent decree pertaining to noise mitigation, the Metropolitan Airports Commission produces an
actual 60 DNL noise contour. Miller noted it shows changes year over year compared to the forecasted
contours that are included in communities’ Comprehensive Guide Plans. For the first time since the
consent decree was adopted, the contours have grown over NE Eagan. The growth in 2017 is due
primarily to arrivals on Runway 30L during the overnight hours. Miller noted that homes must be
included in the actual contours for three consecutive years before being eligible for mitigation.

Item 6: Update on the FAA’s Survey to Re-Evaluate Noise Measurement Metrics
•May 2015 FAA announced it would begin updating the dose-
response relationship between noise exposure and the
percentage of people who are highly annoyed
•This is a part of a larger effort by the FAA, which includes
studying the relationship between noise and sleep
disturbance, cardiovascular health, and children’s cognitive
learning
•FAA has indicated that the survey results are planned to be
released in Q2 2018, however they are still undergoing
inter-agency review (DOD and HUD)
•The results will be released in the form of a report, covering
the purpose of the study, the scientific approach and the
survey results
•FAA has stated that when the results will be released on their website and announced through
the federal register to begin the process of taking stakeholder feedback
•The release of the results will not include any discussion on implications to changing policy
10
Item 6: Update on the FAA’s Survey to Re-Evaluate Noise Measurement Metrics
The survey
•A 12-question survey called the “Neighborhood Environmental Survey” was sent to residents around 20 airports
throughout 2016 and early 2017
•The FAA is not releasing the airports involved in the survey
•The methodology behind the wording of the question, the position of the question within the survey and the
selection of respondents were derived from and/or vetted through the International Committee on the Biological
Effects of Noise (ICBEN), BTS, OMB, social scientists and a pilot project through ACRP
•Airports were selected using the following criteria
–Needed at least 100 annual jet operations
–Needed at least 100 households in the 65 DNL
–Needed at least 100 households in the 60-65 DNL
•The 20 final airports were determined using Balanced Sampling, which ensures the cohort of airports matches the
overall 95 airports on the following factors:
–Geographic balance
–Average temperature
–Number of operations
–% of nighttime operations
–Fleetmix
–Population in the vicinity of the airports
11
Item 6: Update on the FAA’s Survey to Re-Evaluate Noise Measurement Metrics
The survey
•Residents were selected by running noise contours in 5 dB bands from DNL 50-70 using flight
data for the 20 airports
•Their response goal was to have at least 100 respondents per contour band for a total of 500
respondents per airport and a grand total of 10,000 respondents
•The FAA plans to use the Federal Register to publish a link to an FAA website to view the
detailed noise annoyance survey report
•FAA has built a new section of this website with information on the fundamentals of noise and
sound, community response to noise and history of noise:

following sections of the NOC Bylaws:
ARTICLE VIII
Committee Meetings
4. Time and location of NOC meetings
5. Items added to future agendas
6. Public comment period at NOC meetings
28
Item 3: NOC Bylaw Subcommittee Recommendations
Subsection 4 -time and location of NOC meetings. The following ideas
were discussed and received support from the Subcommittee:
•NOC members are strongly suggested to attend Listening Sessions when
able.
•Hold one evening meeting by the NOC each year (suggested November
for approval of the Work Plan).
•Changing the time and location of the NOC meetings should be further
evaluated in the future.
•The Subcommittee members agreed that this section of the Bylaws
should be amended to allow more flexibility for evening meetings.
29
Item 3: NOC Bylaw Subcommittee Recommendations
Subsection 5 –Items added to future agendas. The following ideas
were discussed and received support from the Subcommittee:
•Due to the rigid and lengthy process for adding agenda items to
NOC meeting agendas, the Bylaws should be revised to allow
some flexibility for the Co-Chairs to add items to upcoming
meetings at their discretion.
30
Item 3: NOC Bylaw Subcommittee Recommendations
Subsection 6 –Public comment period at NOC meetings. The following ideas
were discussed and received support from the Subcommittee:
•Remove the requirement in the Bylaws to have speakers sponsored by two (2)
members of the Committee.
•Model the public comment period after “Citizens to be Heard” at city
meetings using “I wish to speak” cards for individuals wishing to make a
comment, then the acting Chairperson can make a final request for those
wishing to speak who did not fill out a card.
•Move the comment period on the agenda to after the monthly operations
update report, however keep this specificity out of the Bylaws to allow
flexibility on the agenda structure.
•The time for the public comment period should be extended from the current
fifteen (15) minutes to twenty (20) minutes with the ability to change it at the
meeting by majority vote.
31
Item 3: NOC Bylaw Subcommittee Recommendations
Subsection 6 –Public comment period at NOC meetings. (Cont’d) The following
ideas were discussed and received support from the Subcommittee:
•The time limit for individual speakers should continue to be three (3) minutes,
but there are some situations where the acting chairperson may need to
allow additional time and that ability should be reflected in the Bylaws.
•The NOC members should have the ability to ask clarifying questions of the
speaker, if necessary.
•MAC Staff should provide the Co-Chairs with a prepared script to open up the
public comment period of the meeting. The script would cover the public
comment guidelines, such as speaking into the microphone, stating name and
address, the speaker’s comment time, and what the Committee does with
comments.
•A section on the macnoise.com website should be created to provide public
comment period guidelines at NOC meetings so individuals wishing to speak
know what to expect. This would include the steps individuals wishing to
speak should go through to provide comment, what they can expect at the
meeting, and what the Committee does with comments.32
Item 3: NOC Bylaw Subcommittee Recommendations
•Proposed redline edits to the Bylaws were included in the
NOC Agenda Packet.
•The Subcommittee proposes to allow time for members to
deliberate the recommendations and come back with the
action at the July 18, 2018 NOC meeting.

Low Less than 3.5 Traffic levels allow for maximum flexibility in
runway selection and RUS implementation,
including the use of unique procedures such as
Opposite Direction.
Mid Between 3.5 and 15 Traffic levels allow for efficient selection of
runways based on noise considerations, given
requirements for runway crossings, capacity,
etc.; moderate use of the RUS.
High Greater than 15 The need to maintain operational capacity does
not allow ATC flexibility in runway selection;
limited use of the RUS.

Remote Monitoring Towers—why do we have them, how do they work?
The MAC has a system of 39 Remote Monitoring Towers (RMTs) to collect aircraft noise levels in
neighborhoods surrounding the airport. These devices are continuously “listening” for aircraft sounds
24 hours per day, 365 days per year.
Each RMT has an "area of influence", which can be thought of as an imaginary cylinder surrounding it.
The size of the area of influence varies based on the location of the RMT. If an aircraft flies through the
area of influence within a certain time window of a noise event then the event is determined to be
caused by the aircraft. When multiple aircraft correlate to the same noise event, the aircraft that is
known to produce louder events is correlated with the event. If there is no aircraft in the area of
influence during the noise event window of time, the event is determined to be caused by a source
within the community.
The noise data collected and matched with MSP arriving and departing planes are published in the
monthly interactive reports on the Noise Program Office website: www.macenvironment.org/reports/.
The noise data collected and reported are helpful when establishing single event noise levels that are
generated by each type of aircraft flying into or out of MSP. The measured noise data are not used to
establish eligibility for the MAC’s residential noise mitigation program.
When developing aircraft noise contours, the MAC must use a federally-approved noise modeling
system and process that incorporates specific details associated with MSP. These details include the
number of each aircraft type that arrives and departs, the destination of the each flight, weather,
runway used and certificated noise levels; the process also considers the time of day that each flight
occurs because a 10 decibel increase is applied to aircraft noises that occur during the nighttime hours
(10-p.m. to 7 a.m.). The metric used to express calculated aircraft noise exposure is Day-Night Level
(DNL). Currently, the MAC is providing residential sound insulation to homes within the 60 decibel DNL
level.
It is important to note that DNL aircraft noise exposure will be greater than measured aircraft noise
because of the applied increase for nighttime aircraft operations.
Has there been an increase in operations over Eagan over the past year? Why? What can we expect
for the year ahead?
No. There has been an overall decrease in the number of flights in and out of MSP during the first five
months of 2018. Over 3,700 fewer flights landed or departed the airport compared to 2017. That is a
reduction of about 2.2 percent.
Over Eagan, close to 2,600 fewer arrivals flew over the City compared to 2017. This is partially offset by
an increase of about 1,450 departures over the City.
The increase in departures over the City is mainly the result of departures from MSP’s Runway 17 (the
north/south runway paralleling Cedar Avenue). It’s no secret that we had a very warm May. In fact, the
average temperature in May was 30 degrees warmer than the average temperature in April, just one
month before. The warm weather conditions in May were brought by southerly winds, necessitating the
40
use of Runway 17 more often. This made a stark contrast for residents living in Eagan under the
departure flights from Runway 17 from April to May. Also contributing to the high use of Runway 17 is
the alignment of the MSP runways. Typically this runway is only used in this direction for departures.
This means that air traffic controllers are able to depart planes from Runway 17 in succession without
having to wait for aircraft to land on the runway as they do on the parallel runways. Fortunately,
Runway 17 is rarely used after 10:30 PM and before 6:00 AM.
Some of the increase in Runway 17 departure activity does not contribute to flights over Eagan. About
40 percent of Runway 17 departures never fly over the City of Eagan. This is especially true when aircraft
are landing on Runways 30L and 30R over Eagan/Mendota Heights. Because of the interplay between
the arrivals and departures, Runway 17 departures are less likely – if ever – to turn over Eagan after
departure. When simultaneously arriving to Runways 30L and 30R, air traffic separation standards
require Runway 17 departures with eastbound destinations to fly south longer before making the turn
toward their final destination. This longer southbound segment avoids the majority of Eagan.
As with typical annual trends, the summer weather is beginning and with it comes a higher prevalence
of south winds. The use of Runways 12L, 12R and 17 for departures should be expected during the
summertime, then recede in the late autumn and winter. Keep updated on flight trends and runway use
on the Interactive Reports section of the MAC Noise website at: www.macenvironment.org/reports/.
What planes are being phased out at MSP?
The most notable fleet change happening today is the retirement of McDonnell Douglas MD-80 aircraft.
This aircraft is equipped with older jet engines, making the aircraft louder on departure than newer
aircraft. Delta Air Lines recently removed MD-80s from its MSP schedule before permanently retiring the
aircraft. Longer-term, Delta has programmed the retirement of its Boeing 757 aircraft. American Airlines
continues to retire its MD-80s as new aircraft come into their schedule.
The MD-80 and Boeing 757 are being replaced by newer single aisle aircraft, specifically the Boeing 737-
MAX aircraft, Airbus A320 NEO aircraft and Bombardier CS-100 aircraft. These new airplanes have new
engines designed to decrease the sound output during departure and improved aerodynamic
technology to reduce airframe noise during arrival. To-date almost 450 new MAX and NEO aircraft have
operated at MSP. The MAC’s system of noise monitors have recorded these new aircraft having a lower
maximum noise level by an average of 3.2 decibels during departure and 1.4 decibels during arrival
compared to the previous models of these aircraft. In addition to lower noise levels, the average
duration of noise events has decreased by 6 seconds on departure and 1.5 seconds on arrival.
