2 nd Quarter 215 Report Fly Quiet Program Chicago O Hare International Airport Visit the O Hare Noise Management Webpage on the Internet at www.flychicago.com/ordnoise
2 nd Quarter 215 Report Background On June 17, 1997, the City of Chicago announced that airlines operating at O Hare International Airport had agreed to use designated noise abatement flight procedures in accordance with the Fly Quiet Program. The Fly Quiet Program was implemented in an effort to further reduce the impacts of aircraft noise on the surrounding neighborhoods. The Fly Quiet Program is a voluntary program that encourages pilots and air traffic controllers to use designated nighttime preferential runways and flight tracks developed by the Chicago Department of Aviation in cooperation with the O'Hare Noise Compatibility Commission, the airlines, and the air traffic controllers. These preferred routes direct aircraft over less-populated areas, such as forest preserves, highways, as well as commercial and industrial areas. As part of the Fly Quiet Program, the Chicago Department of Aviation prepares a Quarterly Fly Quiet Report. This report is shared with Chicago Department of Aviation officials, the O'Hare Noise Compatibility Commission, the airlines, and the general public. The Fly Quiet Report contains detailed information regarding nighttime runway use, flight operations, flight tracks, and noise complaints and 24-hour tracking of ground run-ups. The data presented in this report is compiled from the Airport Noise Management System (ANMS) and airport operation logs. Operations O Hare has eight runways that are all utilized at different times depending on a number of conditions including weather, airfield pavement and construction activities and air traffic demand. The Nighttime Runway Use Report compares the average percentage of use for each runway during the current quarter with the previous quarter as well as with the 12-month average. The percentage of use for departures and arrivals is shown graphically for each runway. This data is presented for all aircraft types during nighttime hours of 1: p.m. to 7: a.m. The Nighttime Hourly Operations Report compares the arrivals and departures by hour to the current quarter with the previous quarter as well as with the 12-month average. Percentage is a ratio whereas a percentage point is the difference between two percentages. Highlights for 2Q 215 include: Departures Arrivals Most used nighttime departure runway: 28R 35% Most used nighttime arrival runway: 27L 37% 22L night departures increased by 12pp from 1Q 215 1C night arrivals increased by 11pp from 1Q 215 28R night departures decreased by 17pp from 1Q 215 27L night arrivals decreased by 11pp from 1Q 215 pp = Percentage Points Nighttime operations represent 11% of the overall daily operations Preferential Flight Tracks As part of the Fly Quiet Program, the Chicago Department of Aviation worked with the O'Hare Noise Compatibility Commission, the airlines, and the air traffic controllers to identify preferred runways and flight tracks for nighttime operations at O Hare. The preferred routes direct aircraft over less-populated areas in an effort to limit the effects of noise on the surrounding communities. Chicago Department of Aviation Page 1 2nd Quarter 215
Adherence to nighttime departure preferential flight tracks is measured by the ANMS. A detailed airline deviation summary is provided for the two most-used departure runways (28R and 32L); the airline deviation is also compared to the data from the same quarter of the previous year. An average deviation graphic and table is provided for all runways. The Nighttime Flight Track Report measures deviation (in nautical miles) from the preferred flight tracks and is divided into three categories: less than.5 miles between.5 and 1. miles greater than 1. miles Noise Complaints The Chicago Department of Aviation maintains a toll-free O Hare noise hotline (1-8-435-9569) and an on-line service at www.flychicago.com/ordnoise for citizens to express their concerns about particular incidents or about aircraft noise levels in general. The Nighttime 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 the complaints during the current quarter. Complaints include all complaints made within the State of Illinois to the O Hare Noise Hotline toll-free number or on-line feature. Ground Run-ups Ground run-ups are aircraft engine tests that are performed to ensure that the engines are working properly after maintenance is performed. Ground run-ups typically occur at night and generate high levels of noise for extended periods of time. In 1997, the Chicago Department of Aviation constructed a ground run-up enclosure (GRE) at O Hare to help reduce the noise impacts of ground run-ups on the communities surrounding the airport. This facility was the first of its kind in the United States. When it is not possible to use the GRE, run-ups are performed on the 1 hold pad. The 32L hold pad is closed as of February 28, 21. The Airline Ground Run-up Report displays the total number of ground run ups from the current quarter by airline. The Aircraft Ground Run-up Report displays the total number of ground run ups from the current quarter by aircraft. Both reports compare the percent utilization of the GRE facility to the percent utilization of other locations for ground run-ups. It also compares the current quarter s GRE usage to the 12-month average and to the same quarter of the previous year. Aircraft Noise The Nighttime Aircraft Noise Report summarizes noise measurements from each of the 33 noise monitors located around O Hare. The data presented summarizes the Equivalent Sound Level (Leq). Leq is used to identify the average sound level over a given period of time (in this case 1 p.m. to 7 a.m.) and is the metric used for this analysis as it is the most appropriate noise measure for periods of time less than 24 hours. The data in this report displays the average Leq for the current quarter and its comparison to the previous four quarters. It also compares the current quarter s Leq to the 12-month average. Numbers displayed in red represent an increase of at least 1 db over the aircraft Leq from the same quarter of the previous year whereas numbers displayed in green represent a decrease of at least 1 db from the aircraft Leq from the same quarter of the previous year.
