The motion carried by unanimous vote.

3 2. Review of Operations Report Summary: July and August 2014 Dana Nelson, Assistant Manager, Noise Environment & Planning, said there was a 21% increase in the number of complaints filed in July 2014 compared to July 2013, and that the number of complaints filed in August 2014 was approximately 1% lower than the number filed in August She said the number of complainants decreased by 12% in July 2014 compared to July 2013, and decreased 6.5% in August 2014 compared to August D. Nelson said total aircraft operations decreased 6% in July 2014 compared to July 2013 and decreased 8% in August 2014 compared to August She said total air carrier jet operations decreased 2% in July 2014 compared to July 2013 and decreased 3% in August 2014 compared to August D. Nelson said regional jet aircraft accounted for 47.7% of the air carrier jet fleet composition in July 2014 and for 47.9% in August She said the balance of the jet fleet composition is made up of manufactured Stage 3 aircraft. She said 0% of the fleet mix is made up of modified Stage 3 aircraft. D. Nelson said there has been a 4-7% increase in passenger counts in 2014 compared to 2013, which indicates passenger load factors are increasing and that airlines are operating more efficiently with larger aircraft and fewer operations. D. Nelson pointed out MSP served approximately 2.4 million passengers in July 2014, the highest number since July D. Nelson said nighttime operations (10:30pm 6:00am) increased 9% in July 2014 compared to July 2013 and increased 15% in August 2014 compared to August She noted that both months had adverse weather condition events, which contribute to delays, than the same months in D. Nelson said Runway 30L received the highest percentage (41%) of arrival operations in July 2014, and the highest percentage (34%) of departure operations in July She said Runway 12R received the highest percentage (37.5%) of arrival operations and highest percentage (33.5%) of departure operations in August She said there were more south flow days in August than in July, allowing ATC to use the RUS more often in August than in July. D. Nelson said there was 99.9% compliance with the Runway 17 Carrier Jet Departure Procedure in both July and August D. Nelson said 98.4% of operations using the Eagan-Mendota Heights Departure Corridor remained in the Corridor in July 2014, and 96.7% remained in the Corridor in August D. Nelson said 49% carrier jet departures used the Crossing-in-the-Corridor Procedure during the nighttime hours of 11:00pm 6:00am during July 2014, and 53% used it in August She said 30% of carrier jet departures used the Procedure during the daytime hours of 6:00am 11:00pm during July 2014, and 39% used it in August Chair Petschel, Mendota Heights, noted that several Committee members would like to work with staff on a way to depict noise complaints that better indicates location, number and trends.

4 3. Presentation: Fleet Scheduling, Delta Air Lines Kevin Mathison, Managing Director Schedule Operations, Delta Air Lines, gave a presentation on fleet scheduling. Highlights of the presentation included: MSP is Delta Air Lines second-largest hub and its 2 nd -3 rd most profitable hub MSP is an efficient east-west connecting hub and the primary gateway to North Dakota to serve shale oil demand 40% of Delta s traffic at MSP is local traffic and 60% is connecting traffic JD Power s large airport satisfaction survey ranked MSP #3; MSP s on-time performance exceeded Chicago-O Hare by nearly 20 points in May 2014 MSP is a valuable connecting hub for Delta due to its mid-continent geography and low congestion Delta s schedule at MSP is designed to meet customer travel preferences; arrivals and departures are organized geographically with groups of inbound flights from the west connecting to outbound flights to the east, and vice versa Delta works to keep operations in banks to capitalize on its schedule design and facilitate the best connectivity to the most destinations; peak hours are the most desirable for airlines, airports and passengers Hourly operations caps would result in a significant drawdown of operations at MSP, and reallocation of operations to open late night or early morning slots An evening curfew at MSP would eliminate afternoon departures from key west coast markets Delta looks at aircraft, capacity, market strengths and opportunities, competitors and route forecasts when creating and managing a new market and related schedules Chair Petschel, Mendota Heights, asked how Delta determines whether or not a demand is emerging in a particular market. Mathison said a connection carriers, sales managers and analysts examine various markets with regard to development to determine whether or not Delta wants to attempt to enter that market. He said Delta s reservation and booking system also captures data that indicate the need for increased flight frequency or for engagement with a specific market. He said the analysts use proprietary and standard software in their analysis work. Representative Quincy, Minneapolis, noted that his constituents are concerned with noise and other environmental impacts created by aircraft operations. He asked if those impacts and operations safety concerns play a role in how Delta schedules operations during early morning and late night hours. Mathison said they do. He said the noise footprint of every aircraft in Delta s fleet is analyzed and that Delta takes into consideration which aircraft can be used for which operations to minimize impact. With regard to when operations are scheduled, Mathison noted that customer demand drives those decisions. Representative Bergman, At-large Representative, noted that Delta is removing the from its operations at MSP and asked what impact that would have on the noise environment. Mathison said he could not answer that question quantitatively without conducting a noise study based on a schedule, but that qualitatively the aircraft being brought in the A330s and the A321s are the latest generation aircraft that are Stage 4 compliant. He noted those aircraft can climb high enough and quick enough to minimize noise impact. He noted that Delta wants to be a good community partner.

5 4. FAA CatEx2 Comments John Nelson, Technical Advisor, noted that Section 213(c)(2) of the FAA Modernization and Reform Act of 2012 concerns the use of a Categorical Exclusion (CatEx) for the environmental review of PBN procedures that result in a measureable reduction of aircraft noise, fuel consumption and carbon dioxide emissions on a per flight basis. He said the FAA has requested public comment on elements of the requirements and noted that it has had difficulty engaging the per-flight noise reduction element. He said the FAA appointed an advisory body to address the issue and that the advisory body came up with the net noise reduction method. J. Nelson summarized the method by saying it looks at noise contours drawn at 45-60, 60-65, and 65+ DNL and the net reduction or increase in impacted population. J. Nelson noted that the Committee chairs, in consultation with staff, developed comments to the FAA s proposed use of a Categorical Exclusion for the environmental review of PBN procedures, focusing on: The need for the FAA to involve airport operators and communities early on in the development of PBN procedures In circumstances where concerns or opposition are present, the FAA must participate in discussions with local community leaders to establish community expectations related to outreach efforts The removal of the consideration of extraordinary circumstances is a flaw that is not addressed by the proposed Net Noise Reduction Method The FAA should return to the US Congress and seek clarification on the legislative intent and consider providing a process that evaluates community noise impact concerns effectively Representative Bergman, At-large Representative, noted that the Committee s comments to the FAA concern MSP, and he asked if comments to the FAA will be responded to as a group, or if the FAA will respond directly to the Committee about its comments with regard to MSP. Chair Petschel, Mendota Heights, said she expects it would be both. Bergman asked if staff has had any contact with other airports about the FAA s proposal. Chad Leqve, Director of Environment, said that airports around the US are monitoring the proposal and that it s likely a number of other airports will submit comments. He said he does not believe the circumstances, and therefore impacts, are the same at all airports. Representative Quincy, Minneapolis, noted that the City of Minneapolis has a long-held opposition to any categorical exclusion, and he said that position is consistent with the position expressed to the city s legislative delegation and to the House and Senate staff authors. He said it s also consistent with the position of the National Organization to Insure a Soundcontrolled Environment (NOISE). He said the City of Minneapolis will submit comments to the FAA and will sign on to the comments submitted to the FAA by NOISE. The Committee held a voice vote with regard to forwarding to the FAA the CatEx2 comment letter as drafted and included in Committee members meeting packet. The Committee voted unanimously to forward the letter to the FAA.

6 5. Study: Seasonal Effects on Aircraft Operations John Nelson, Technical Advisor, reminded Committee members a copy of the Seasonal Impacts on Aircraft Operation Levels and Performance, August 2014 report was included in their meeting packets. He noted the study showed: Strong correlation between passenger demand and operations at MSP At MSP, operations: are at peak levels in July and August; begin to decline in September; increase in mid-october due to MEA weekend; decline November- February; steadily increase in March-July 2014 year-to-date is trending toward fewer operations than 2013 Wind direction and speed, plus air traffic demand levels, are important considerations in seasonal runway use variances for arrivals and departures, in addition to runway closures, runway maintenance, etc. Aircraft departures from MSP have an average lower altitude at 2.5 miles (-439 feet) and 5 miles (-627 feet) from MSP during warm weather Arrival operations were roughly equally distributed on Runways 30L, 12L, 12R and 35, during , although there was a higher number of arrivals during that period on Runway 30R During , Runways 30L and 30R were used most frequently for departure operations, followed by Runway 17; during that same period, Runway 12R was used less than Runway 12L for departure operations Chair Petschel, Mendota Heights, said Committee members have remarked on changing weather patterns and trends in the area over the past few years, and she said it may be of interest to the group to bring in a meteorologist for discussion. 6. Runways 12L, 12R, and 17 Departure Trends John Nelson, Technical Advisor, noted that when MSP is in a south flow configuration, ATC directs aircraft to depart to the southeast using Runways 12L and 12R and to the south using Runway 17, and to arrive from the northwest on Runways 12L and 12R. He said that, in this configuration, Runway 17 is used only for departures, the benefit of which is that ATC does not have to sequence departing aircraft on Runway 17 as they do on Runways 12L and 12R. J. Nelson said concern has been expressed that there are fewer departures off of Runway 12R than off of Runway 12L.He said that concern was validated in the departure trends study. He said the question was raised as to whether more departures could be placed on Runway 12L and the number of departures off of Runway 17 be reduced. He said the FAA has stated that maintaining separation requirements for safe operations would be difficult in that scenario, and that the number of operations that could be handled in that scenario would be reduced which would stretch operations out over a longer period of time. J. Nelson noted that MSP is a northern tier airport, with departures to destinations to the south, southeast, southwest and west. He noted that Runway 17 is aligned such that ATC is able to fan departure operations off of that runway in the direction of their ultimate destinations effectively and safely. Representative Miller, Eagan, noted that the challenge is that the runway use preferences don t match up with the 2007 forecast. She said that explaining to residents the RUS abilities and limitations is a messaging issue that may need to be addressed.

7 7. Draft 2015 NOC Work Plan John Nelson, Technical Advisor, reminded Committee members of the work plan development process: Members will comment on the Draft 2015 NOC Work Plan prior to the 19 November 2014 meeting At the 19 November 2014 meeting, the finalized Work Plan will be presented to the Committee for approval and adoption The Committee Co-chairs will present the Work Plan to the MAC Planning, Development & Environment Committee, which will forward the Plan on to the MAC Full Commission J. Nelson reviewed the Draft 2015 NOC Work Plan items with the Committee. He suggested item 2e, Status of FAA Center of Excellence/PARTNER, TRB and FICAN initiatives and item 2h, Review Health Effects of Aircraft Operations Epidemiological Studies be merged into one item. Representative Quincy, Minneapolis, noted that the City of Minneapolis requested information on the RUS from the FAA and that the FAA, in its response, deferred that request to the NOC saying the NOC would have more impact on operations. Quincy suggested some engagement with the RUS should be on the 2015 Work Plan. Chair Petschel, Mendota Heights, asked if a continued and regular dialogue with the FAA through the NOC address Quincy s concern. Quincy said he thought that it might. Quincy said he would work with J. Nelson on language to include in the Work Plan. Representative Bergman, At-large Representative, wondered about the FAA s statement that the NOC would have impact on operations. Quincy agreed, saying it was the City s understanding that the FAA had that responsibility. Petschel noted that the FAA s letter stated that the NOC would be the appropriate venue for an ongoing dialogue between the cities and the FAA. Committee members should forward any changes or suggestions to the Draft 2014 NOC Work Plan to J. Nelson prior to the next Committee meeting on 19 November Review of 29 July 2014 Public Input Meeting John Nelson, Technical Advisor, said there 23 people attended the third quarter 2014 Public Input Meeting, and that 11 people spoke on the record at the meeting. He said questions and concerns raised at the meeting included: Aircraft taking early turns that result in flights north of the Eagan-Mendota Heights Corridor boundary Increased use of runway 17 for departures, which results in flights over residential areas of Bloomington and Eagan Early morning engine run-ups Suggested improvements for responses to the Public Input Meeting s sent to the MAC Moving MSP operations to Rochester and St. Cloud Written responses will be sent to those residents who commented on the record, and the written responses will be posted on the Noise Program Office website, The next Public Input Meeting will be held at 7:00pm on Tuesday, 28 October 2014 at the Metropolitan Airports Commission General Offices, th Avenue South, Minneapolis.

8 9. Public Comment Period There were no public comments. The next meeting of the NOC is scheduled for Wednesday, 19 November The meeting adjourned at 3:06pm. Respectfully Submitted, Christene Sirois Kron, Recording Secretary

32 St. Louis Park and Edina Noise Monitoring Study Introduction On May 8, 2014, the members of the Minneapolis St. Paul International Airport (MSP) Noise Oversight Committee (NOC) directed the Metropolitan Airports Commission (MAC) Noise Program Office staff to conduct a noise monitoring study in the cities of St. Louis Park and Edina subject to the following conditions: The noise monitoring will be focused on assessing existing aircraft noise levels. The noise monitoring will be conducted for a period of two weeks in the fall of The monitoring will be limited to three locations in the area bound by I 494 on the south, Xerxes Avenue on the east from the intersection of I 494 and Xerxes Avenue extending in a straight line north to I 394, I 394 on the north, and Trunk Highway 169 on the west. Two of the monitoring locations will be within the City of Edina and one will be located in the City of St. Louis Park. The specific location of the monitors shall be determined by the respective cities, in consultation with MAC staff. The final report is due by December 1, The NOC members identified the need for the study due to increased public concern regarding the potential changes in noise levels in the affected communities from the proposed implementation of Area Navigation (RNAV) flight procedures for arrivals and departures at MSP. In February 2014 the Federal Aviation Administration (FAA) notified the MAC that RNAV departures would not be implemented due to safety concerns arising from the MAC proposal to have RNAV departure procedures implemented on all runways except 30L and 30R. However, the FAA did indicate that Standard Terminal Arrival Routes (STARs) using RNAV would be implemented at MSP. Further, the STARs procedures would include Optimized Profile Descents (OPDs) for the aircraft approaches to MSP. STARs implementation at MSP is expected to begin in March and April, Sound Level Meter Site Selection Process The NOC At Large representatives from the cities of St. Louis Park and Edina and the MAC Noise Program Office staff collaborated on an analysis leading to the final site selection for the three sound level meters (SLM). This analysis focused on a number of specific criteria designed to ensure the security of the SLMs and to accurately and completely capture aircraft noise levels. These criteria are provided below: 1. Public land, owned by the city (parks, easements, out lots, etc.) was preferred for the site due to the short term duration of the study and the monitoring schedule. 2. The noise monitoring sites needed to be distant from community noise sources such as highways, arterial streets, active construction sites, areas where crowds assemble, and railroad tracks, etc. 1 P age

33 3. The noise monitoring sites needed to correspond with the departure density maps provided in the NOC Technical Advisor s Monthly Reports. Areas with increased density of overflights were preferred to meet the objective of measuring aircraft noise levels. 4. Residential areas were preferred for the final locations in order to capture aircraft noise levels within residential areas. In keeping with the criteria, the NOC At Large members representing Edina and St. Louis Park and MAC staff examined radar flight track patterns within the proposed study area using the Metropolitan Airports Commission Airport Noise and Monitoring System (MACNOMS) flight track data. The boundaries of the study area are shown in the map below: Figure 1 Source: MAC Noise Program Staff map. The City of St. Louis Park was found to have a number of operations on the final approach flight path associated with arrivals on Runways 12R and 12L, and, to a lesser extent, straight out departures from Runways 30L and 30R. Arrival flight tracks are shown in Figure 2. The City of Edina has a greater flight track density in the southwest and southeastern quadrants of the city comprised of departures from Runway 30L 2

34 and, to a lesser extent, westbound departures from Runway 30R. Departure flight tracks are shown in Figure 3. Figure 2 Source: MACNOMS Flight Tracker, August 28, 2014, 24 hours of arrivals. Figure 3 Source: MACNOMS Flight Tracker August 29, 2014, 24 hours of departures. 3

36 Noise Monitoring Measurement Methods Monitoring Period Noise event monitoring and data collection began at 12:00 a.m. on August 22, 2014 and concluded at 11:59 p.m. on September 4, This monitoring project was conducted by the staff of the MAC Noise Program Office. Equipment Laboratory quality noise monitoring equipment manufactured by Larson Davis Incorporated (LD) was placed at each site. The main sound measurement components of each set up included a Type 1 LD 824 sound level meter, a LD PRM902 preamplifier, and a LD 2541 microphone. This equipment is calibrated and certified annually by the manufacturer. Analysis Parameters The sound level meter at each site monitored noise levels continuously utilizing slow response with A weighting, as directed by 14 CFR Part 150. The sound level meter detected an event when the sound pressure level (SPL) reached a threshold of 65 db and recorded events when the SPL remained at or above 63 db for eight seconds or longer. Recorded events were then correlated with flight track data obtained from MACNOMS to determine whether the noise source was associated with a specific aircraft operation. Parameters used to correlate noise events and radar flight tracks included two dimensional distance, altitude and time. Aircraft noise events that were not generated by operations associated with MSP were excluded from the data. DNL Noise Metric The Day Night Average Sound Level (DNL) metric is utilized by the FAA to assess aircraft noise impact. The DNL is a cumulative measure of noise exposure during a 24 hour day with a 10 db penalty added to noise events occurring between the hours of 10:00 p.m. and 7:00 a.m. Aircraft DNL reflects only aircraft events. Aircraft noise is generally considered by the FAA to be significant when levels reach an annual average daily DNL of 65 db or greater, (cumulative measure of 365 days). An annual aircraft DNL at or above 65 db is considered by the FAA to be incompatible with residential areas and other noise sensitive land uses. Runway Use and Operations during the Monitoring Period The arrival and departure operations from August 22, 2014 to September 4, 2014 on the runways of interest are shown in Table 1 below: 5

All operations includes carrier jet, cargo, and general aviation aircraft types. 2. % of All Runway Use is the percentage of operations on listed runways as a portion the total arrival and departure operations on all MSP runways during the monitoring period. Noise Monitoring Results This study effectively collected aircraft event data in the cities of Edina and St. Louis Park. Given that the purpose of the study was to measure existing aircraft noise levels, a number of evaluation methods used in the Monthly NOC Technical Advisor s Report and similar reports prepared for the St. Paul Downtown Airport were used for data analysis. These techniques include Flight Density Maps, Time Above db Thresholds for Arrival and Departure Related Noise Events, Arrival and Departure Related Noise Event Counts, and aircraft event monitoring site average daily DNL levels. Flight Density Maps Figure 5 shows the density of flight tracks for arrivals and departures for all hours and the flight tracks of nighttime hours of the monitoring period. The flight density and nighttime operations flight tracks shown are typical of normal operations at MSP. Arrivals on Runways 12R and 12L are depicted as a narrow track over St. Louis Park as the aircraft align with the runways on the final approach heading (shown in the yellow, orange and red density tracks). Aircraft departing on Runway 30L and bound for destinations south of Minnesota are given instructions by the air traffic controllers to initiate a turn on a 260 or a 280 heading, which places the flight track on a path toward Edina. Because the turn is executed at slightly different times 6

38 by each aircraft, and because there are specific aircraft separation requirements, the departure flight tracks over Edina show more dispersion (shown in the pink, purple and blue density tracks).

39 Time above db Thresholds for Arrival and Departure Related Noise Events The time above a set db threshold is used to evaluate the length of time, or duration, at the monitoring site above a given sound level. Runway use configuration at MSP is the sole responsibility of the FAA Air Traffic Control Tower (ATCT), and runway use can vary from hour to hour and day to day. There are times when the ATCT may be using Runways 30L and 30R for departures in a north flow of air traffic and other times when Runways 12L and 12R may be used for arrivals in a south flow of air traffic. There are hours during the day with high air traffic demand and hours during the night when air traffic demand is low. Over the 14 days of monitoring, there were a total of 336 hours of noise measurements recorded. Table 2 shows the Time Above the thresholds of 65 db and 80 db in hours, minutes, and seconds for the arrivals at MSP during the monitoring period at each monitoring site. There were no aircraft arrival events with one second Leq values greater than 90 db. The Leq is an average sound level over a given time period; it is a single number that is the equivalent of the average sound pressure level of a noise event that has fluctuating sound pressure level values throughout the event.

40 Arrival and Departure Related Noise Event Counts Table 4 shows the number of aircraft and non aircraft noise events at each monitoring location that met the analysis parameter of 65 db and a sustained sound pressure level of 63 db for eight seconds. These data affirm the effect of arrival operations on Runway 12R at the St. Louis Park site and the effect of departure operations from Runway 30L at the Edina sites. In addition, the data affirm the selected site locations met the objective of data collection for arrival and departure noise events. Aircraft events are those events that correlate the aircraft flight tracks with the correct time frame and the location of the sound level meter.

Due to the logarithmic nature of noise events, the loudest noise levels control the 24 hour average. In addition, the DNL calculation adds a 10 db penalty to each aircraft operation during the nighttime hours from 10 p.m. to 7 a.m. The Measured Daily Aircraft DNL represents the DNL levels for each day while the Measured 2 Week Average Aircraft DNL represents the average DNL level for the duration of the study period. For comparison and validation purposes, the Integrated Noise Model 2013 Annual Actual Noise Contour study was utilized to calculate the Modeled 2013 Aircraft DNL values at the monitoring location. While this modeled DNL value takes an average of 365 days of operations, the levels correlate well with the Measured 2 Week Average Aircraft DNL levels at each site, as shown by 9

41 the blue and yellow lines in the charts below. At St. Louis Park Site 101, these lines are overlapping since the Measured 2 Week Average Aircraft DNL and the Modeled 2013 Aircraft DNL are both 54.7 dba. The chart for Edina Site 102 shows that on August 24, August 28 and September 3 there were no aircraft noise events that influenced the DNL levels on those specific days. Further analysis of flight data determined that, over the 24 hours of each day, MSP operations were departing to the south and aircraft were not proximate to the Edina monitoring sites. The chart for Edina Site 103 also shows that there were no aircraft noise events that influenced the DNL levels on August 24 and 28.

58 ITEM 7 MEMORANDUM TO: MSP Noise Oversight Committee (NOC) FROM: John Nelson, Manager Noise, Environment and Planning SUBJECT: AIRCRAFT ALTITUDE GRAPHICS DATE: September 3, 2014 Altitudes of departing aircraft are dependent on a number of flight performance variables such as engine thrust setting, weight, aircraft performance and directions given by Federal Aviation Administration Air Traffic Control, among others. Recent research presented to the Noise Oversight Committee described changes in average aircraft altitude that are attributed largely to seasonal weather patterns and air temperature. For example, during very hot days the air is less dense and departing aircraft do not gain altitude as rapidly as a similarly configured aircraft would gain on a cold day. The Flight Tracker Application available to the public at has an Animated Flight Track Replay feature that allows the user to define time periods 15 minutes in length and display the aircraft altitude in feet above MSP. Other filters on the feature allow the user to display Flight ID, Heading (Degrees), Aircraft Type, and Speed (MPH). An example of the Animated Flight Track Replay altitude display is shown below. The numbers just above the green aircraft figures represent the altitude in feet above MSP. In addition to the Flight Tracker application, MAC staff can produce custom programmed gate penetration charts using internal computer software. Examples of two of the gate penetration

59 charts used in the Seasonal Operations Effects Study in the September 17, 2014 NOC Meeting Agenda packet are shown below: 5 Miles from MSP July 2014 Gate 4 (Southeast) Departures 2,194 flights Aircraft Mean Altitude = 2,857 feet Altitude (feet) Distance Along Gate (miles) January 2014 Gate 4 (Southeast) Departures 1,310 flights Altitude (feet) Aircraft Mean Altitude = 3,091 feet Distance Along Gate (miles) MAC Noise Office Program staff are currently examining the potential to add user defined penetration gate functionality to the Flight Tracker application. This added feature would allow members of the public to set the penetration gate dimensions and download the altitude data from the Metropolitan Airports Noise and Operations Monitoring System (MACNOMS). Penetration gate data can be further analyzed for general comparison purposes to examine seasonal variations in altitude month to month and year to year, as shown below:

60 Altitude in Feet Above MSP Elevation of ,500 3,000 2,500 2,000 1,500 1, Average Runway 12R/12L Departure Altitudes at Gate 4, 5 miles SE of MSP Source: Seasonal Operations Effects Study September Year January July An advantage of the penetration gate analysis is the ability to display the linear density and altitude patterns of multiple flights and single flights at fixed distances from MSP. Penetration gates can be produced for gates of user defined width and height. Additionally, data can be filtered to show specific time periods, aircraft types, runways, arrivals and departures. In addition, Geographical Information System (GIS) software can be used to display altitude gradient maps, or average altitude on a grid, as shown below.

61 Summary Aircraft altitudes can be displayed by using several methods including animated flight track replays, penetration gate analysis, worksheet charts, gradient maps and raster maps. These tools allow Noise Program Office staff to analyze trends in average altitude for multiple aircraft flight tracks as well as very specific altitude data for individual aircraft flight tracks. At the November 19 th Noise Oversight Committee meeting staff will provide a presentation on this topic.
