Airport Noise Management System Quarterly Report Report Descriptions Background Installed in 1996, the Airport Noise Management System (ANMS) enables the City of Chicago to monitor the amount of noise being generated over the communities surrounding Midway by the aircraft operating at the Airport. The ANMS collects, analyzes and processes data from a number of sources of information including a network of 12 noise monitors around Midway, FAA radar data, weather data and calls to the noise hotline. Over 120,000 flights and 400,000 noise events are recorded by the ANMS each month for the Chicago Department of Aviation. The City of Chicago and the Midway Noise Compatibility Commission utilize data from the ANMS to facilitate the development and management of noise abatement programs at the Airport. The following reports summarize pertinent monthly information from that data concerning the noise levels and operations at the Airport. Runway Use Report The five runways at Midway are utilized at different times primarily depending upon the prevailing wind conditions on the airfield, as well as any runway maintenance. Aircraft performance requirements make it necessary for aircraft to depart and land into the wind for safety reasons. The Runway Use Report presents the average number of daily operations on each runway, the percentage of use for each runway and a 12 month average. The percentage of use for each runway is shown graphically for departures and arrivals. This data is for all hours of the day and night and for all aircraft types in October, November and December 2009. Percentage is a ratio whereas a percentage point is the difference between two percentages. Highlights for the 4 th Quarter of 2009 include: Departures Arrivals Most used departure runway: 31C 45% Most used arrival runway: 31C 46% 22L & 22R departures increased 13pp from 3Q 2009 31C increased 13pp from 3Q 2009 04L & 04R departures decreased 19pp from 3Q 2009 04L & 04R arrivals decreased 24pp from 3Q 2009 pp = Percentage Points Noise Hotline Report The Chicago Department of Aviation (CDA) maintains a toll-free noise hotline (1-800-914-8537) and an on-line service at www.flychicago.com for citizens to express their concern about particular aircraft events or aircraft noise levels in general. The Noise Hotline Report summarizes the number of complaints received and where the complainants were located. The tabular report lists the number of complaints by community as well as the number of individual complainants. The graph at the bottom of the page illustrates the nature of complaints during the specified month. Also shown are complaints by month displaying seasonal trends. The chart at the top of the next page illustrates the trend in monthly complaints. These totals only include complaints made within the State of Illinois to the Midway Noise Hotline toll-free number or on-line feature. City of Chicago Department of Aviation Page 2 4th Quarter 2009

The report is summarized in four ways: operations for each airline during all hours of the day; operations for each airline during the nighttime hours (10 p.m. to 7 a.m.); percent of total operations for each airline during all hours of the day and percent of total operations during the nighttime hours. This report displays the average operations at Midway International Airport during the calendar quarter indicated. Aircraft Fleet Mix Report The Aircraft Fleet Mix Report summarizes the number and type of aircraft operating at Midway International Airport. The report is summarized in four ways: fleet mix for each airline during all hours of the day; fleet mix for each airline during the nighttime hours (10 p.m. to 7 a.m.); percent of total fleet mix for each aircraft type during all hours of the day and percent of total fleet mix by aircraft type during the nighttime hours. This report displays the average fleet mix at Midway International Airport during the calendar quarter indicated. In 1990, Congress enacted legislation to eliminate all Stage 2 aircraft operating in the continental United States by the year 2000. In response, the FAA created a program to phase-out the older, louder Stage 2 aircraft over a ten-year period to achieve full compliance by the 2000 deadline. As of January 2000, all aircraft operating at Midway and within the United States were Stage 3. Stage 3 aircraft, such as the Boeing 757 (B757) and new Boeing 737 s (B737) use a quieter type of engine that significantly reduces noise at the source. Also, a Stage 3 aircraft can be a previous Stage 2 aircraft with the engines retrofitted with a Hush-kit such as a Boeing 727 (B72Q), Boeing 737-200 (B73Q) and DC-9 (DC9Q). More than 99% of the operations at Midway International Airport are originally certified as Stage 3 aircraft. Aircraft Noise Report The Aircraft Noise Report summarizes noise measurements from each of the 12 noise monitors located around the Airport. The data presented summarizes the Day-Night Average Sound Levels (DNL). DNL is a 24-hour time-averaged sound exposure level with a 10 decibel (db) nighttime (10 p.m. to 7 a.m.) weighting to account for the lower background noise levels during the nighttime hours. The data displays the measured aircraft DNL for each quarter and its comparison to the same quarter of the previous year, and it compares the current quarter to the 12-month average. The aircraft noise report identifies noise from the existing aircraft operations at Midway International Airport. City of Chicago Department of Aviation Page 3 4th Quarter 2009
