2 Airport Noise Management System Monthly Report Report Descriptions CHCAGO ;::y &Q:JA DEPARTMENT OFAVAnON Background nstalled 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 O'Hare 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 32 noise monitors around O'Hare, FAA radar data, weather data and noise complaints. Over 12, flights and 4, noise events are recorded by the ANMS each month for the Chicago Department of Aviation (CDA). The City of Chicago and the O'Hare 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 O'Hare has seven runways that are all utilized at different times depending primarily 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 purposes. The Runway Use Report presents the average percentage of use for each runway for the current month, the previous month and a 12month average. The percentage of use for departures and arrivals is shown graphically for each runway. This data is for all hours of the day and for all aircraft types. Also shown is the runway use for the nighttime hours (1 p.m. to 7 a.m.). Percentage is a ratio whereas a percentage point is the difference between two percentages. Highlights for November 212 include: Departures Arrivals Most used departure runway: 22L 45 /o Most used arrival runway: 27L 21% 22L departures increased by Bpp from October R arrivals increased by 3pp from October departures decreased by 6pp from October 212 4R arrivals decreased by 2pp from October 212 pp = Percentage Points Aircraft Noise Report The Aircraft Noise Report summarizes noise measurements from each of the 32 noise monitors located around the Airport. The data presented summarizes the DayNight Average Sound Levels (DNL's). DNL is a 24hour timeaveraged sound exposure level with a 1 decibel (db) nighttime (1 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 month and its comparison to the same month of the previous year, and it compares the current month to the 12month average. The aircraft noise report identifies noise from the existing aircraft operations at O'Hare. The modeled values for each monitor are shown for 1997, 2 and the OMP Build Out Noise Contours. The aircraft noise levels for each monitor vary from month to month. This is primarily due to runways being utilized differently under changing wind conditions which effect where the aircraft fly.

3 Aircraft Fleet Mix Report The Aircraft Fleet Mix Report summarizes the number and type of aircraft operating at O'Hare nternational Airport during both all hours of the day and during the nighttime hours. n 199, Congress enacted legislation to eliminate all Stage 2 aircraft operating in the continental United States by the year 2. n response, the FAA created a program to "phaseout" the older, louder Stage 2 aircraft over a tenyear period to achieve full compliance by the 2 deadline. As of January 2, all aircraft operating at O'Hare 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 "Hushkit" such as a Boeing 727 (B72Q), Boeing 7372 (B73Q) and DC9 (DC9Q). More than 99% of the operations at O'Hare nternational Airport are originally certified as Stage 3 aircraft. Noise Co~plaint Report The Chicago Department of Aviation (CDA) maintains a tollfree noise hotline ( ) and an online service at for citizens to express their concern about particular aircraft events or aircraft noise levels in general. The Noise Complaint 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 bottom of this page illustrates the trend in monthly complaints. These totals only include complaints made within the State of llinois to the O'Hare Noise Hotline tollfree number or online feature.
