4 th Quarter 2014 Quarterly Report Airport Noise Management System Visit the Midway Noise Management webpage on the Internet at www.flychicago.com
Airport Noise Management System Quarterly Report Report Descriptions Background Installed in 1996, the Airport Noise Management System (ANMS) enables the City of to monitor the amount of noise being generated over the communities surrounding Midway International Airport (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 noise complaints. Over 150,000 flights and 400,000 noise events are recorded by the ANMS each month for the Department of Aviation (CDA). The City of 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 of 2014. Percentage is a ratio whereas a percentage point is the difference between two percentages. Highlights for the 4 th Quarter of 2014 include: Departures Arrivals Most used departure runway 31C 45% Most used arrival runway: 31C 46% 22L and 22R departures increased 8pp from 3Q 2014 31C arrivals increased 18pp from 3Q 2014 04L & 04R departures decreased 18pp from 3Q 2014 04L and 04R arrivals decreased 23pp from 2Q 2014 pp = Percentage Points Airline Fleet Mix Report The Airline Fleet Mix Report summarizes the number of operations by airline operating at Midway International Airport. 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 Department of Aviation Page 1 4th Quarter 2014
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 phaseout the older, louder Stage 2 aircraft over a tenyear 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 hushkit such as a Boeing 727 (B72Q), Boeing 737200 (B73Q) and DC9 (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 DayNight Average Sound Levels (DNL). DNL is a 24hour timeaveraged 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 12month average. The aircraft noise report identifies noise from the existing aircraft operations at Midway International Airport. Noise Hotline Report The Department of Aviation (CDA) maintains a tollfree noise hotline (18009148537) and an online 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 tollfree number or online feature.
