Technical Advisor s Report Summary Recent concerns from residents around the airport: - Aircraft departure altitudes - Frequency of flights - Nighttime operations - Noise levels 6

Aircraft Departure Altitude Trends RMT locations were used to assess altitudes of aircraft operations since 2011. Operations were filtered to include only Runway 30L Departure altitudes. RMTs 1, 3, 5, 7 and 27 record aircraft noise events from Runway 30L Departures. 7

Aircraft Departure Altitude Trends RMT locations were used to assess altitudes of aircraft operations since 2011. Operations were filtered to include only Runway 30R Departure altitudes. RMTs 2, 4, 6, 8 and 29 record aircraft noise events from Runway 30R Departures. 8

Aircraft Departure Altitude Trends RMT locations were used to assess altitudes of aircraft operations since 2011. Operations were filtered to include only Runway 12R Departure altitudes. RMTs 14, 16, 22, 24, 25 and 26 record aircraft noise events from Runway 12R Departures. 9

Aircraft Departure Altitude Trends RMT locations were used to assess altitudes of aircraft operations since 2011. Operations were filtered to include only Runway 12L Departure altitudes. RMTs 13, 15, 21, 22, 23 and 26 record aircraft noise events from Runway 12L Departures. 10

Aircraft Departure Altitude Trends RMT locations were used to assess altitudes of aircraft operations since 2011. Operations were filtered to include only Runway 17 Departure altitudes. RMTs 25, 30, 31, 32, 33, 34, 35, 36, 37, 38 and 39 record aircraft noise events from Runway 17 Departures. 11

Frequency of Flights/Nighttime Operations The daytime hourly operational trends for the first 6 months of 2015 are consistent with previous years. The peak hour of operations currently occurs from 1:00-2:00pm with 81.3 average daily flights. This is lower than the peak hours of operations in 2014 (87.3) and 2013 (95.6). 2004 is included to show a comparison to the peak year of operations at MSP. Total operations increase in 2015 between 11 p.m. and 6 a.m. Number of Operations 25000 20000 15000 10000 5000 0 Hourly Operations January - June 2015 2014 2013 2004 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 12 Hour

Frequency of Flights/Nighttime Operations During the first 6 months of 2015 departure operations increased during the 5 a.m., 7 a.m., 9 a.m. and 8 p.m. hours. Some airlines are scheduling more flights during the nighttime period. In April 2015 AAL added 2 daily departures to Dallas/Fort Worth and Charlotte in the 5 a.m. hour. Number of Operations 12000 10000 8000 6000 4000 Hourly Departures January - June 2015 2014 2013 2004 SWA added 2 weekday departures to Kansas City and Milwaukee in the 5 a.m. hour. 2000 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Hour 13

Historic Noise Level Comparisons Since 2008 the number of events above 65 db are trending downward. Reduction in total operations. Reduction in Hushkit /Modified Stage 3 aircraft. Replaced by newer technology, quieter aircraft. The trend will likely continue as aircraft manufacturers are designing and manufacturing quieter, more efficient aircraft. Between 2014 and 2015 there was a slight increase. Warmer average temperatures in 2015 (on average, about 7 warmer than 2014). Reduction in small 50-seat RJ aircraft. 15

LTCP Noise Analysis 2035 Forecast vs. 2030 Forecast (from 2010 LTCP) The 2035 Forecast 65 DNL noise contour is 59.6% smaller than what was forecasted in the 2010 LTCP for the 2030 65 DNL noise contour. The 2035 Forecast 60 DNL noise contour is 47.7% smaller than what was forecasted in the 2010 LTCP for the 2030 60 DNL noise contour. In total, there are 7,005 fewer single-family homes and 6,398 fewer multi-family units inside the 2035 Forecast 60 DNL contour as compared to what was forecasted in the 2010 LTCP for the 2030 60 DNL noise contour.

During the EA/EAW process, runway use percentages were determined based on airport and airspace simulation, with consideration of the RUS and the FAA s runway selection patterns relative to operational flows, weather conditions and aircraft destinations and origins. The RUS is a major factor in nighttime runway use percentages. Sometimes during the nighttime when there is low demand, the FAA will use the parallel runway closest to the aircraft arrival gate. As a result, arrival percentages to the south parallel runway (12R/30L) at night are higher than the north parallel (12L/30R). This has an effect on the arrival noise contour lobes off the ends of the south parallel runway. *INM Night 10:00 pm-7:00 am Note: Total may not add up to 100% due to rounding.

Noise Oversight Committee July 22, 2015 Item 5 Sunfish Lake Noise Monitoring Study Scope The 2015 NOC Work Plan includes a remote noise monitoring study to be conducted in the City of Sunfish Lake. The purpose of the study will be to assess existing aircraft noise levels in the City of Sunfish Lake. 50

Sunfish Lake Mobile Noise Monitoring Study Scope MAC Staff is proposing the following project scope: The noise monitoring will be focused on assessing existing aircraft noise levels. The noise monitoring will be conducted for a period of one week in late summer 2015. The monitoring will be limited to one location under known aircraft overflights within the boundaries of the City of Sunfish Lake. The specific location of the noise monitor shall be determined by the City of Sunfish Lake, in consultation with MAC staff. 51

Sunfish Lake Mobile Noise Monitoring Study Scope Requested Action DIRECT THE MAC NOISE PROGRAM OFFICE STAFF TO CONDUCT THE NOISE MONITORING STUDY AS DETAILED ABOVE IN THE CITY OF SUNFISH LAKE. THE NOISE MONITORING REPORT SHALL BE COMPLETED BY SEPTEMBER 16, 2015 AND BE PROVIDED TO THE NOISE OVERSIGHT COMMITTEE AND THE CITY OF SUNFISH LAKE. 52

Noise Oversight Committee July 22, 2015 Item 6 Area Navigation (RNAV) Standard Terminal Arrival Routes (STARs) Update On March 24, 2015 FAA implemented Area Navigation RNAV STARs On April 30, 2015 FAA implemented Required Navigation Performance (RNP) STARs Use of Optimized Profile Descents (OPD) is a critical component Initial estimates show over 80% of MSP arrivals were issued OPDs since implementation 53

Area Navigation (RNAV) Standard Terminal Arrival Routes (STARs) Update CRJ Example Arrival MAC Staff is partnering with the FAA Airports Planning and Environmental Division Significant expansion of the MSP flight tracking dataset at no cost Staff is currently facilitating expanded analysis to assess OPD usage at MSP Altitude (feet) 30000 25000 20000 15000 10000 RNAV arrival Conventional Arrival Goal of calculating the associated fuel savings and emission reductions through collaboration with the airlines 5000 0 0 50 100 150 200 250 Miles from MSP 54

Concerns about RNAV STARS causing lower aircraft arrival altitudes. RMT locations were used to assess arrival altitudes of aircraft operations since 2011. Arrival altitude trends are consistent with previous years. Operations were filtered to include only Runway 12R Arrival altitudes. RMTs 1, 3 and 5 record aircraft noise events from Runway 12R Arrivals. Area Navigation (RNAV) Standard Terminal Arrival Routes (STARs) Update 56

Area Navigation (RNAV) Standard Terminal Arrival Routes (STARs) Update Arrival altitude trends are consistent with previous years. Operations were filtered to include only Runway 12L Arrival altitudes. RMTs 2, 4 and 6 record aircraft noise events from Runway 12L Arrivals. 57

Area Navigation (RNAV) Standard Terminal Arrival Routes (STARs) Update Arrival altitude trends are consistent with previous years. Operations were filtered to include only Runway 30L Arrival altitudes. RMTs 14, 16, 22 and 24 record aircraft noise events from Runway 30L Arrivals. 58
