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) 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 13 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 (MNCC) 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. Wind Summary Wind is a key factor influencing runway use and operation. Aircraft performance requirements make it necessary for aircraft to take off and land into the wind for safety purposes. Ideally, aircraft should take off and land into the wind as the increased airflow over the wings provides improved lift. The diagram to the right summarizes the percent of wind occurrences by direction based on hourly data from the KMDW Automated Surface Observing System (ASOS), which is a joint effort of multiple government agencies. Aircraft Operations Summary The chart below illustrates the trend in monthly aircraft operations at Midway. Total monthly operations are based on the FAA s Air Traffic Activity Data System (ATADS).

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 2017. Percentage is a ratio whereas a percentage point is the difference between two percentages. Highlights for the 4 th Quarter of 2017 include: Departures Arrivals Most used departure runway: 31C 47% Most used arrival runway: 31C 46% 31C departures increased 12pp from 3Q 2017 31C arrivals increased 15pp from 3Q 2017 04L and 04R departures decreased 21pp from 3Q 2017 04L and 04R arrivals decreased 24pp from 3Q 2017 pp = Percentage Points Airline and Aircraft Fleet Mix Reports The Airline Fleet Mix Report summarizes the number of operations by airline operating at Midway. 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. The Aircraft Fleet Mix Report summarizes the frequency and type of aircraft operating at Midway. 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 passed the Airport Noise and Capacity Act (ANCA) to create a more comprehensive method for regulating aircraft noise. ANCA tasked the FAA with establishing a national noise policy, as well as substituted advances in quiet engine technology for restrictions on airport operations. These aircraft noise standards are codified in FAA Part 36 regulations, Noise Standards: Aircraft Type and Airworthiness Certification. Aircraft must meet Part 36 standards to receive type or airworthiness certificates to operate in the United States. There are five stages of noise standards for aircraft: Stage 1, Stage 2, Stage 3, Stage 4, and Stage 5. Currently, all aircraft operating at Midway and within the United States are Stage 3 or 4. These aircraft, such as the Airbus A320 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. More than 99% of the operations at Midway are originally certified as Stage 3 aircraft. Stage 5 noise standards will apply to new aircraft designed, manufactured, and certificated after December 31, 2017. Aircraft Noise Report The Aircraft Noise Report summarizes aircraft noise measurements from each of the 13 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. Department of Aviation Page 2 4th Quarter 2017
Noise Complaint Report The Department of Aviation (CDA) maintains a toll-free noise hotline (1-800-914-8537) and a webpage at www.flychicago.com/midwaynoise 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 quarters. These totals only include complaints made within the State of Illinois to the Midway Noise Hotline toll-free telephone number or webpage.
