1 Recommendations for Northbound Aircraft Departure Concerns over South Minneapolis March 21, 2012 Noise Oversight Committee Agenda Item #4 Minneapolis Council Member John Quincy

2 Background Summer of 2011 saw an increase in flights and noise near Cedar Ave. due to departures off of 30R Initial hypothesis was safety change due to near miss in fall of 2010 Requested additional information from FAA Response from FAA at January 2012 NOC meeting indicated More flights off 30R due to 2010 change in departure (crossing on the ground) Fleet mix currently 54% Regional Jets (CRJ) Lower altitudes More similar tracks Shorter intervals

3 Minneapolis Requests COMMITTEE ACTION Request that the MAC Planning and Environment Committee endorse these action items: Move the approximately 32 daily departure operations flying to Duluth, International Falls, Winnipeg, etc. from Runway 30R to 30L. Implement the use of three divergent headings (360 o, 340 o, 320 o ) for north bound departure operations off Runway 30R. Continue adherence to the Runway Use System (RUS) at all times when traffic levels and prevailing winds allow. Further request that the MAC send a letter to the FAA requesting implementation of the above operational measures as soon as is possible. Additionally, we request that MAC staff conduct an analysis of NADP on 30R and 30L and report the effects of each NADP procedure at the next NOC meeting in May

4 Move Northerly Departures from 30R to 30L Departures to Duluth, International Falls and Winnipeg, etc., move to 30L 32 from a total of approximately 250 departures/day (13%) Near term implementation

5 Multiple divergent departure headings Similar to RNAV, but tracks not as precise A smaller portion of traffic would use a 360 o heading than current condition Other flights would use 340 o and/or 320 o departure heading 6 months before implementation

7 Reminder to use the Runway Use System (RUS) RUS has been in place for decades Updated most recently as part of the EA for Runway 17/35 Nothing new in this request - just a reminder to FAA Basis of mitigation around the airport

8 Return to 2003 Noise Abatement Departure Profile (NADP) Change from Distant to Close-in NADP Use planes power to gain altitude rather than speed Planes fly slightly higher Planes would be slower For an A320 basically no difference in altitude 4 miles from takeoff (approximately Lake St.) Request a staff report presented to NOC at the May meeting

9 NOC COMMITTEE ACTION Request that the MAC Planning and Environment Committee endorse these action items: Move the approximately 32 daily departure operations flying to Duluth, International Falls, Winnipeg, etc. from Runway 30R to 30L. Implement the use of three divergent headings (360 o, 340 o, 320 o ) for north bound departure operations off Runway 30R. Continue adherence to the Runway Use System (RUS) at all times when traffic levels and prevailing winds allow. Further request that the MAC send a letter to the FAA requesting implementation of the above operational measures as soon as is possible. Additionally, we request that MAC staff conduct an analysis of NADP on 30R and 30L and report the effects of each NADP procedure at the next NOC meeting in May Discussion

17 Annual MSP Noise Contour Report Noise Litigation Consent Decree: Consent Decree Section 8.1(d) pp : (d) By March 1 of each year, MAC shall develop and make available to the public a noise contour report using the FAA s Integrated Noise Model to reflect noise conditions from the prior calendar year, using actual MSP operations data derived from the Airport Noise and Operations Monitoring System or a functionally equivalent flight tracking and noise monitoring system ( Monitoring System ). This noise contour report shall contain, at a minimum: (1) the noise contour for the previous calendar year; (2) a grid point analysis of noise levels associated with the contour; (3) comparisons in grid points and graphic form of the difference in noise levels between the previous calendar year s contour and the 2007 DNL level; and (4) comparison to actual and monitored noise levels from MAC s Monitoring System, consistent with previous validation analyses. MAC shall consult with the Plaintiffs during the development of the previous year contour report. On February 29, 2012 MAC staff completed the fifth Annual Noise Contour Report consistent with the above provision.

18 2011 Annual MSP Noise Contour Report

19 2011 Annual MSP Noise Contour Report

20 2011 Annual MSP Noise Contour Report Total Operations The 2011 actual total MSP operations number of 435,076 represents a 25.3 percent reduction from the 2007 forecast mitigated total operations number of 582,366. Scheduled passenger air carrier and cargo operations accounted for the majority of the reduction. However, it is notable that charter operations are 97.2 percent below the 2007 forecast mitigated number. The 2011 total operations number of 435,076 is down slightly from the 2010 number of 435,583 (0.1 percent decrease).

21 2011 Annual MSP Noise Contour Report Fleet Mix and Day/Night Ops. Split The hushkitted Stage 3 average daily operations in the 2011 actual statistics were down 92.0 percent from the 2007 forecast mitigated number. Nighttime operations decreased by 16.5 average daily operations from the 2007 forecast mitigated to the 2011 actual operations statistics. The average daily number of hushkitted aircraft operations was down in 2011 to 21.9 from 64.7 in In 2011, the average daily number of total nighttime operations was 106.8, up from the 93.4 average daily nighttime operations in 2010.

22 2011 Annual MSP Noise Contour Report Runway Use Use of Runway 17 for departure operations is well below the percentage use numbers forecasted in the 2007 mitigated scenario. The departure percentage on Runways 30L and 30R are notably higher, and the departure percentages on Runway 12R are notably lower, than what was forecasted in the 2007 forecast mitigated scenario. The nighttime departure percentage on Runway 17 is significantly lower, and the Runways 30L and 12L nighttime departure percentages are significantly higher, than the levels forecasted in the 2007 forecast mitigated scenario. The 2011 total arrival percentages correlated fairly well with the 2007 forecast mitigated scenario. Nighttime arrival percentages on Runways 12R and 30L are significantly higher, and significantly lower on Runway 35, than the levels forecasted in the 2007 forecast mitigated scenario.

24 2011 Annual MSP Noise Contour Report Additional Considerations INM Version 6.1 v. INM Version 7.0a - New lateral attenuation capabilities incorporated into INM 7.0a have the effect of increasing the size of the 2011 actual noise contour by as much as 3% to 10% over what INM 6.1 would have modeled. New Flight Analysis Methodology - The radar-to-inm flight track correlation process that the MAC used to develop the 2011 actual noise contour employs a best-fit analysis of the radar flight track data based on linear trends. This approach provides the ability to directly match each radar flight track to the appropriate INM track. The enhanced ability to interpret similarities along a track, rather than solely at a gate location, provides the ability to analyze all INM tracks as core tracks.

26 2011 Annual MSP Noise Contour Report 2007 Forecast v Actual Contours The 2011 actual noise contour is smaller than the 2007 forecast mitigated contour by 6,397.5 acres (40.7 percent reduction) in the 60 DNL contour and by 3,342.2 acres (46.2 percent reduction) in the 65 DNL contour. The small area where the 2011 actual noise contour extends beyond the 2007 forecast mitigated noise contour can largely be attributed to runway use variances between what was forecasted and what was occurring in There is an overall decrease of 2,961 residential units in the 65 DNL contour and 3,877 residential units in the 60 to 64 DNL noise contours around MSP when comparing the 2007 forecast mitigated contour with the 2011 actual contour that the MAC developed under the requirements of the Consent Decree.

27 2011 Annual MSP Noise Contour Report 2011 Actual v. Monitored DNL Levels

28 2011 Annual MSP Noise Contour Report Conclusions Primary Areas of Insight: INM and Flight Track Modeling Enhancements Total Operations Fleet mix Runway Use Nighttime Operations *Note: The 2011 count of residential units within the actual 60 DNL noise contour that have not received noise mitigation around MSP is 633, a reduction of 53.4 percent from the total of 1,359 based on the 2010 actual noise contours. There are no unmitigated homes in the 2011 actual 65 DNL noise contour around MSP. All homes within the 2011 actual 60+ DNL contours will be mitigated by 2014 by virtue of the noise litigation Consent Decree. This significant reduction is due in large part to a 66.2 percent reduction in hushkitted aircraft operations from 2010 to 2011.

29 Nighttime Operations Assessment As is outlined in the 2012 NOC Work Plan, staff has prepared an assessment of nighttime operations at MSP Resident concerns and comments made at Input Meetings are one of the primary catalysts for the continuing evaluation of nighttime operations at MSP Analysis focuses on the following: Average daily nighttime operations at MSP from 2002 to 2011 Annual average daily INM nighttime operations from 2002 to 2011 compared to the 2007 forecast annual average daily nighttime operations MSP all nighttime and carrier jet nighttime operations runway use summary for 2011 and 2010 MSP INM nighttime (10:00 p.m. to 7:00 a.m.) operations runway use summary for 2011 and 2010 A breakdown of the top 15 nighttime carrier jet operators for 2011 and 2010 A breakdown of the fleet mix for the top 15 nighttime airlines for 2011 and 2010 Average daily MSP nighttime operations by hour for 2011 and 2010 A comparison and breakdown of scheduled nighttime operations and the fleet mix of the scheduled operations for 2011 and 2010 A comparison of the scheduled nighttime operations vs. actual nighttime operations for 2011 and 2010 Federal policy (grant provisions/part 161) virtually prohibits mandatory nighttime restrictions Part 150 measure: NA-3 Voluntary Nighttime Limit on Flights

37 First Quarter 2012 Public Input Meeting On January 24, 2012 the First Quarter 2012 Noise Public Input Meeting was held 32 people attended the meeting 13 people commented at the meeting staff has provided written responses that are available at A summary memo of the input was provided in the meeting mailing to all NOC members Comments focused largely on the northbound departure turn issue in Minneapolis in addition to the following points: The use of noise complaints Increased noise causing substantial economic displacement, substantial impact to home values and impact on quality of life, physical and mental health MAC not taking responsibility/ownership for problem and pushing it off on FAA MAC should be proactive on this issue MAC is favoring the airlines on this issue; can't MAC ask airlines to slow down departure rates to provide relief to impacted areas

38 First Quarter 2011 Public Input Meeting (cont.) Questions about who controls the number of operations per hour at the airport, who controls the number of operations per hour off of the runways, who has oversight of airlines' fleet mix and if airlines are giving forethought to how changes to fleet mix will impact the noise footprint when they decide which aircraft to use Question about whether or not the MAC and/or the NOC can make requirements of the FAA in relation to ground operations and takeoff procedures Questions about whether or not the MAC believes DNL contours are still accurate and request to redraw the contour maps to reflect the current situation, questions about how the RMTs work (re: not recording the first 8 seconds of an event) and questions about installing new RMTs in affected neighborhoods Vibration/low frequency as an issue The next quarterly public input meeting is planned for April 24, 2012.
