4 About the Roundtable The Airport/Community Roundtable was established in May 98, by a Memorandum of Understanding (MOU), to address noise impacts related to aircraft operations at San Francisco International Airport (SFO). The Airport is owned and operated by the City and County of San Francisco, but it is located entirely within San Mateo County. This voluntary committee consists of appointed and elected officials from the City and County of San Francisco, the County of San Mateo, and several cities in San Mateo County (see attached Membership Roster). It provides a forum for the public to address local elected officials, Airport management, FAA staff, and airline representatives, regarding aircraft noise issues. The committee monitors a performance-based aircraft noise mitigation program, as implemented by Airport staff, interprets community concerns, and attempts to achieve additional noise mitigation through a cooperative sharing of authority brought forth by the airline industry, the FAA, Airport management, and local government officials. The Roundtable adopts an annual Work Program to address key issues. In 07, the Roundtable is scheduled to meet on the first Wednesday of the following months: February, April, June, August, October and December. Regular Meetings are held on the first Wednesday of the designated month at 7:00 p.m. at the David Chetcuti Community Room at Millbrae City Hall, 0 Poplar Avenue, Millbrae, California unless noted. Special Meetings and workshops are held as needed. The members of the public are encouraged to attend the meetings and workshops to express their concerns and learn about airport/aircraft noise and operations. For more information about the Roundtable, please contact Roundtable staff at (60) 6-8. POLICY STATEMENT The Airport/Community Roundtable reaffirms and memorializes its longstanding policy regarding the shifting of aircraft-generated noise, related to aircraft operations at San Francisco International Airport, as follows: The Airport/Community Roundtable members, as a group, when considering and taking actions to mitigate noise, will not knowingly or deliberately support, encourage, or adopt actions, rules, regulations or policies, that result in the shifting of aircraft noise from one community to another, when related to aircraft operations at San Francisco International Airport.

7 Aircraft Noise Abatement Office Glossary of common Acoustic and Air Traffic Control A terms ADS-B - Automatic Dependent Surveillance Broadcast ADS-B uses ground based antennas and in-aircraft displays to alert pilots to the position of other aircraft relative to their flight path. ADS-B is a key element of NextGen. Air Carrier - A commercial airline with published schedules operating at least five round trips per week. Air Taxi An aircraft certificated for commercial service available for hire on demand. ALP - Airport Layout Plan The official, FAA approved map of an airport s facilities. ALS Approach Lighting System - Radiating light beams guiding pilots to the extended centerline of the runway on final approach and landing. Ambient Noise Level The existing background noise level characteristic of an environment. Approach Lights High intensity lights located along the approach path at the end of an instrument runway. Approach lights aid the pilot as he transitions from instrument flight conditions to visual conditions at the end of an instrument approach. APU - Auxiliary Power Unit A self-contained generator in an aircraft that produces power for ground operations of the electrical and ventilation systems and for starting the engines. Arrival The act of landing at an airport. Arrival Procedure - A series of directions on a published approach plate or from air traffic control personnel, using fixes and procedures, to guide an aircraft from the en route environment to an airport for landing. Arrival Stream A flow of aircraft that are following similar arrival procedures. ARTCC Air Route Traffic Control Center - A facility providing air traffic control to aircraft on an IFR flight plan within controlled airspace and principally during the enroute phase of flight. ATC - Air Traffic Control - The control of aircraft traffic, in the vicinity of airports from control towers, and in the airways between airports from control centers. ATCT Air Traffic Control Tower - A central operations tower in the terminal air traffic control system with an associated IFR room if radar equipped, using air/ground communications and/or radar, visual signaling and other devices to provide safe, expeditious movement of air traffic. Avionics Airborne navigation, communications, and data display equipment required for operation under specific air traffic control procedures. Altitude MSL Aircraft altitude measured in feet above mean sea level. B Backblast - Low frequency noise and high velocity air generated by jet engines on takeoff. Base Leg A flight path at right angles to the landing runway. The base leg normally extends from the downwind leg to the intersection of the extended runway centerline. C Center See ARTCC. CNEL Community Noise Equivalent Level - A noise metric required by the California Airport Noise Standards for use by airport proprietors to measure aircraft noise levels. CNEL includes an additional weighting for each event occurring during the evening (7;00 PM 9: PM) and nighttime (0 pm 6: am) periods to account for increased sensitivity to noise during these periods. Evening events are treated as though there were three and nighttime events are treated as thought there were ten. This results in a.77 and 0 decibel penalty Meeting 0 - Dec 6, 07 Packet Page 7

8 penalty for operations occurring in the evening and nighttime periods, respectively. CNEL Contour - The "map" of noise exposure around an airport as expressed using the CNEL metric. A CNEL contour is computed using the FAA-approved Integrated Noise Model (INM), which calculates the aircraft noise exposure near an airport. Commuter Airline Operator of small aircraft (maximum size of 0 seats) performing scheduled (maximum size of 0 seats) performing service between two or more points. D Decibel (db) - In sound, decibels measure a scale from the threshold of human hearing, 0 db, upward towards the threshold of pain, about 0-0 db. Because decibels are such a small measure, they are computed logarithmically and cannot be added arithmetically. An increase of ten db is perceived by human ears as a doubling of noise. dba - A-weighted decibels adjust sound pressure towards the frequency range of human hearing. dbc - C-weighted decibels adjust sound pressure towards the low frequency end of the spectrum. Although less consistent with human hearing than A- weighting, dbc can be used to consider the impacts of certain low frequency operations. Decision Height The height at which a decision must be made during an instrument approach either to continue the approach or to execute a missed approach. Departure The act of an aircraft taking off from an airport. Departure Procedure A published IFR departure procedure describing specific criteria for climb, routing, and communications for a specific runway at an airport. Displaced Threshold - A threshold that is located at a point on the runway other than the physical beginning. Aircraft can begin departure roll before the threshold, but cannot land before it. DME - Distance Measuring Equipment - Equipment (airborne and ground) used to measure, in nautical miles, a slant range distance of an aircraft from the DME navigational aid. DNL - Day/Night Average Sound Level - The daily average noise metric in which that noise occurring between 0:00 p.m. and 7:00 a.m. is penalized by 0 db. DNL is often expressed as the annual-average noise level. DNL Contour - The "map" of noise exposure around an airport as expressed using the DNL metric. A DNL contour is computed using the FAA-approved Integrated Noise Model (INM), which calculates the aircraft noise exposure near an airport. Downwind Leg A flight path parallel to the landing runway in the direction opposite the landing direction. Duration - The length of time in seconds that a noise event lasts. Duration is usually measured in time above a specific noise threshold. E En route The portion of a flight between departure and arrival terminal areas. Exceedance Whenever an aircraft overflight produces a noise level higher than the maximum decibel value established for a particular monitoring site, the noise threshold is surpassed and a noise exceedance occurs. An exceedance may take place during approach, takeoff, or possibly during departure ground roll before lifting off. F FAA - The Federal Aviation Administration is the agency responsible for aircraft safety, movement and controls. FAA also administers grants for noise mitigation projects and approves certain aviation studies including FAR Part 0 studies, Environmental Assessments, Environmental studies, Environmental Assessments, Environ Impact Statements, and Airport Layout Plans.

Review of Airport Director s Reports for May and June 7, Review of SFO FlyQuiet Report for Q Airport Director s Comments Roundtable Chairperson Lewis indicated that items five, six, and seven would be consolidated and addressed by SFO s Public Information Officer Doug Yakel. Mr. Yakel provided an overview of how the airport will handle updates and report briefings during Roundtable meetings that focused on data overview, actions and mitigation, and airport activities updates. Mr. Yakel mentioned that SFO s decision to move forward with the installation of a Ground-Based Augmentation System (GBAS), SFO would like to present to the Roundtable an overview of GBAS at the next regular meeting. Roundtable members asked several questions of the reports and presentations Mr. Yakel mentioned during his presentation. Mr. Yakel indicated that SFO was open to modifications that the Roundtable was felt more meaningful and useful for the group. It was clarified that the data reflective in the illustrations are complaints per city, and perhaps it should be discussed as a group as to how to calculate/collect complaints (standalone versus consolidated) as was raised by some members. Additional comments and concerns were raised regarding the value of a heat-map of complaints. Chairperson Lewis noted that this is a work in progress, and it s important for the airport to show us what they re developing and then the Roundtable can provide feedback as to what to add or subtract.

Fly Quiet Report Presented at the December 6, 07 Airport Community Roundtable Meeting Aircraft Noise Abatement Office Third Quarter 07 Meeting 0 - Dec 6, 07 Packet Page 9

30 Fly Quiet Program San Francisco International Airport s Fly Quiet Program is an Airport Community Roundtable initiative implemented by the Aircraft Noise Abatement Office. Its purpose is to encourage individual airlines to operate as quietly as possible at SFO. The program promotes a participatory approach in complying with noise abatement procedures and objectives by grading an airline s performance and by making the scores available to the public via newsletters, publications, and public meetings. Fly Quiet offers a dynamic venue for implementing new noise abatement initiatives by praising and publicizing active participation rather than a system that admonishes violations from essentially voluntary procedures. Program Goals The overall goal of the Fly Quiet Program is to influence airlines to operate as quietly as possible in the San Francisco Bay Area. A successful Fly Quiet Program can be expected to reduce both single event and total noise levels around the airport. Program Reports Fly Quiet reports communicate results in a clear, understandable format on a scale of 0-0, zero being poor and ten being good. This allows for an easy comparison between airlines over time. Individual airline scores are computed and reports are generated each quarter. These quantitative scores allow airline management and flight personnel to measure exactly how they stand compared to other operators and how their proactive involvement can positively reduce noise in the Bay Area. Program Elements Currently the Fly Quiet Program rates jets and regional jets on six elements : the overall noise quality of each airline s fleet operating at SFO, an evaluation of single overflight noise level exceedences, a measure of how well each airline complies with the preferred nighttime noise abatement runways, assessment of airline performance to the Gap and Shoreline Departures, and over the bay approaches to runways 8L and 8R. Meeting 0 - Dec 6, 07 Packet Page 0

31 SFO s Fly Quiet Ratings Fleet Noise Quality The Fly Quiet Program Fleet Noise Quality Rating evaluates the noise contribution of each airline s fleet as it actually operates at SFO. Airlines generally own a variety of aircraft types and schedule them according to both operational and marketing considerations. Fly Quiet assigns a higher rating or grade to airlines operating quieter, new generation aircraft, while airlines operating older, louder technology aircraft would rate lower. The goal of this measurement is to fairly compare airlines not just by the fleet they own, but by the frequency that they schedule and fly particular aircraft into SFO. Noise Exceedance Eliminating high-level noise events is a long-standing goal of the Airport and the Airport Community Roundtable. As a result the Airport has established single event maximum noise level limits at each noise-monitoring site. These thresholds were set to identify aircraft producing noise levels higher than are typical for the majority of the operations. Whenever an aircraft overflight produces a noise level higher than the maximum decibel value established for a particular monitoring site, the noise threshold is surpassed and a noise exceedance occurs. An exceedance may take place during approach, takeoff, or possibly during departure ground roll before lifting off. Noise exceedances are logged by the exact operation along with the aircraft type and airline name. Nighttime Preferential Runway Use SFO s Nighttime Preferential Runway Use program was developed in 988. Although the program cannot be used 00% of the time because of winds, weather, and other operational factors, the Airport, the Community Roundtable, the FAA, and the Airlines have all worked together to maximize its use when conditions permit. The program is voluntary; compliance is at the discretion of the pilot in command. The main focus of this program is to maximize flights over water and minimize flights over land and populated areas between :00 a.m. and 6:00 a.m. Fortunately, because airport activity levels are lower late at night, it is feasible to use over-water departure procedures more frequently than would be possible during the day. Reducing nighttime noise especially sleep disturbance is a key goal of SFO s aircraft noise abatement program. Shoreline Departure Quality Aircraft departing SFO using Runways 8L and 8R are also considered by the Fly Quiet grading system whenever they use the Shoreline Departure Procedure. This predominately VFR (visual flight rules) departure steers aircraft to the northeast shortly after takeoff in an attempt to keep aircraft and aircraft noise away from the residential communities located to the northwest of SFO. By keeping aircraft east of Highway 0 the majority of the overflights will be experienced by industrial and business parks instead of residential areas. In order to evaluate each airline s performance when flying a Shoreline Departure, a corridor was established using Interstate 0 (green colored flight tracks) as a reference point. The corridor runs north along 0, beginning approximately one-mile north-northwest of the end of Runways 8L and 8R and continuing up into the City of Brisbane. Departures west of 0 are scored marginal or poor depending on their location. Gap Departure Quality Aircraft departing SFO using Runways 8L and 8R frequently depart straight out using a procedure known as the Gap Departure. This procedure directs air traffic to fly a route that takes them over the area northwest of the airport over the cities of South San Francisco, San Bruno, Daly City, and Pacifica. In an attempt to mitigate noise in this specific area, the Gap Departure Quality Rating has been included as a category in the Fly Quiet Program. Since higher is quieter, aircraft altitudes are recorded along the departure route. Scores are assigned at specified points or gates set approximately one mile apart, with the higher aircraft receiving higher scores. Foster City Arrival Quality The Arrival Quality Rating is the latest addition to the Fly Quiet Program. In an effort to further reduce nighttime noise in neighboring communities, this rating is designed to maximize over-bay approaches to Runways 8 between :00 p.m. and 6:00 a.m. Airlines arriving to Runways 8 during these hours are assessed based on which approach flight path was used. Over-the-bay approaches are rated good (green colored flight tracks), versus over-the-communities which are rated poor. Meeting 0 - Dec 6, 07 Packet Page Revised date: //09

43 SAN FRANCISCO INTERNATIONAL AIRPORT CITY & COUNTY OF SAN FRANCISCO MEMORANDUM TO: BRISBANE COMMUNITY FROM: SAN FRANCISCO INTERNATIONAL AIRPORT AIRCRAFT NOISE ABATEMENT OFFICE SUBJECT: Q 07 BRISBANE NOISE MONITORING REPORT DATE: NOVEMBER 7, 07 The San Francisco International Airport (SFO) Aircraft Noise Abatement Office conducts aircraft noise monitoring in the City of Brisbane, California to determine noise levels within the community from aircraft operations at SFO. Noise monitoring occurs every quarter for a -day data collection period. This quarter s measurement period was from July 6, 07 to August 8, 07. The monitoring is made possible with the assistance of the City Manager and School Superintendent, resulting in two temporary sites in Brisbane. The first site, Site 966 was located at The Mission Blue Center and the second site, Site 988 was located at Lipman Middle School. The overall average daily noise level from all aircraft at Site 966 was 6 A-weighted decibels Community Noise Equivalent Level (CNEL), and at Site 988 the aircraft CNEL was dba. The Community daily noise level at Site 966 was dba CNEL and at Site 988, it was dba. Noise from all aircraft increased the total average daily noise level by.dba at Site 966 and.6dba at Site 988. SFO aircraft comprised 9% of all aircraft noise events over Site 966 and 80% over Site 988. During the monitoring period, SFO had two weekends (July 9-0 and August -6) where departures from Runways 0L/R (Left/Right) were suspended due to construction work. All departures utilized Runways 8L/R during this closure. This caused a decrease in flights over Site 966 and increased the amount of flights over Site 988 due to aircraft using the TRUKN and NIITE departure procedures. Non-aircraft noise sources included residential noise, vehicular traffic, and wind noise. Brisbane is located approximately miles from the airport. The city typically experiences aircraft utilizing the SSTIK and OFFSHORE departure procedures. Aircraft departing SFO from Runways 0L/R for destinations to the west, south and southeast typically overfly Brisbane. Occasionally when the winds on the airfield are stronger from the west, the TRUKN OR NIITE departures will be utilized for destinations to the east. Departing aircraft from Runways 8L/R will initiate a right turn once the aircraft reaches the minimum altitude of 0 feet, consequently this may have some aircraft fly over Brisbane. SFO traffic arriving from the north on the BDEGA, STINS or GOLDEN GATE arrival on a typical day (West Plan) overfly Brisbane at 0,000 feet or higher. The ambient levels within Brisbane during the monitoring period were as follows: Site 966-9dBA and Site 988-0dBA. On an average day, Site 966 had overflights. 6% exceeded the noise monitor thresholds and recorded a noise event. The threshold was set at 6dBA for the monitoring period. Site 988 had 6 overflights, 8% exceeded the noise monitor threshold and recorded a noise event. The threshold was set at dba for the monitoring period. During the noise-monitoring period, SFO Aircraft Noise Abatement Office received noise reports from 6 individuals in Brisbane. Majority of aircraft noise events at Site 966 occurred between am and 7pm. At Site 988 it was between 7am and 6pm. On average, there were only nighttime noise events at Site 966 and 7 nighttime events at Site 988. In view of the fact that the monitoring locations in Brisbane are located in a suburb with ambient noise of 0dBA, any aircraft noise above this threshold may become a nuisance for the residents. dba- stands for A-weighted decibel. Decibel unit measures the loudness of a sound and is computed as the signal to noise ratio. A-weighting is used to adjust for frequency range of human hearing. An increase of ten decibels is perceived by human ear as a doubling of noise. SEL - Sound Exposure Level of a noise event is measured over time between the initial and final points when the noise level exceeds a predetermined threshold and its energy is compressed into one second. LMax - The maximum noise level is a measurement of the peak level of a noise event. CNEL- This metric is used to assess and regulate aircraft noise exposure in communities surrounding the airport. California Title Noise Regulations established acceptable level of aircraft noise of 6dBA CNEL. West Plan Standard operations at the Bay Area International Airports. Aircraft arrive to the west at all three airports. At San Jose and Oakland Airports, aircraft depart to the west. While at San Francisco Airport, aircraft depart either to the north or to the west depending on wind conditions on the airfield. TRUKN and NIITE RNAV departure procedures off Runways 8L/R at SFO, has aircraft climb heading of 8 to 0 feet then right turn to initial fix.

49 SAN FRA N CISCO INTERNATIO NA L AI RPO R T CITY & COUNTY OF SAN FRANCISCO MEMO RANDU M TO: MONTARA COMMUNITY FROM: SAN FRANCISCO INTERNATIONAL AIRPORT AIRCRAFT NOISE ABATEMENT OFFICE SUBJECT: MONTARA SHORT-TERM NOISE MONITORING REPORT DATE: OCTOBER, 07 The San Francisco International Airport (SFO) Aircraft Noise Abatement Office conducted aircraft noise monitoring in Montara to determine the noise levels within the community from aircraft operations at SFO. The monitoring was made possible with the assistance of a Montara resident. The overall average daily noise level from all aircraft was dba CNEL. The Community daily noise level was dba CNEL. Noise from all aircraft over this location increased the total average daily noise level by dba. SFO aircraft attributed % of all aircraft noise events over Montara community. During the noise monitoring period there were no weather or other impacts that would cause delays, require use of reverse flow or alter the flight patterns in any way. Non-aircraft noise sources included dogs barking. Montara is a quiet suburban community with ambient noise levels of 8dBA. On an average day, Montara had overflights out of which 6 exceeded the noise monitor threshold of dba and recorded a noise event. Flights departing SFO bound for destination airports in the south or southeast; will turn left over the peninsula and continue their path south using a published departure procedure or as directed by Federal Aviation Administration Air Traffic Controllers. As these flights overfly parts of coastal communities they represent percent of all aircraft noise events over Montara, and are typically at or above 0,000 feet. Oakland departures add additional 0 percent to these flights. About 0 percent of aircraft noise events over Montara is low-flying general aviation traffic heading to Half Moon Bay Airport or transitioning to the smaller aviation airports such as San Carlos and Palo Alto. An average sound exposure level (SEL) for a single noise event for all aircraft were recorded at 7dBA and maximum noise levels (LMax) at 8dBA. SFO and Oakland aircraft have lower LMax and SEL levels and are quieter than the general aviation traffic as they overfly the area about 8,000 feet higher. During the noise monitoring period SFO Aircraft Noise Abatement Office received noise reports from six individuals in the Mid-Coast communities. Majority of aircraft noise events occurred between 9am and 9pm, and on average, there were only four nighttime noise events. In view of the fact that the monitoring location in Montara is located in a quiet suburban community with ambient noise in the quiet 0dB range, any aircraft noise above this threshold may become a nuisance for the residents. dba- stands for A-weighted decibel. Decibel unit measures the loudness of a sound and is computed as the signal to noise ratio. A-weighting is used to adjust for frequency range of human hearing.

54 The California Code of Federal Regulations, Title, Division., Chapter 6, paragraph 0 states, The standard for the acceptable level of aircraft noise for persons living in the vicinity of airports is hereby established to be a community noise equivalent level of 6 decibels. Since the average Aircraft CNEL was measured at dba for Montara, this residential area has an acceptable level of aircraft noise as defined by state law. The extent of the 6dBA CNEL noise impact contour at SFO is shown above. This noise contour was generated using Federal Aviation Administration s Integrated Noise Model (version 7.0d). The Federal Aviation Administration accepted this map as part of the Noise Exposure Map update under Federal Aviation Regulations Part 0 on January 9, 06. The results of the field monitoring validate the extent of the 6dBA CNEL noise impact boundary confirming Aircraft CNEL is less than 6dBA CNEL for this location. Meeting 0 - Dec 6, 07 Packet Page
