The O’Hare Noise Compatibility Commission met on June 1, 2018

The Commission welcomed Dr. Belur Shivashankara (Shankar) of Boeing. Dr. Shankar is the Senior Technical Fellow and Executive responsible for innovating and incorporating low noise technologies at Boeing Commercial Airplanes. He has led several major noise technology programs supporting various airplane programs including 747,777, 737, and 787 airplanes.

IMG 0161 350Dr. Shankar stated that Boeing’s goal is to build airplanes that can fly more quietly, according to procedures that are acceptable to all stakeholders. Dr. Shankar reviewed progress thus far and examined how aircraft have evolved and improved. He explained that Boeing is continually developing new airplanes to replace existing models. Improvements include less carbon dioxide emissions, greater fuel efficiency, quieter engines and smaller noise footprint. A theme throughout his presentation that efficient airplanes are also quieter airplanes. Technological advancements in fuel efficiency have contributed to aircraft also generating less noise. He described several types of tests and analysis that the company performs, such as active flight testing where they partner with different carriers to test new technology on existing aircraft. One example of such a test was a flight utilizing 100% biofuel, containing higher energy content per gallon, which greatly reduces pollution. In another test, they placed thousands of microphones at the end of a runway to determined exactly where on the plane noise was coming from. The microphones helped to create a “heat map” of noise on the plane. Dr. Shankar concluded by stating that collaboration with stakeholders within the ecosystem is key to minimizing noise impact – airplane manufacturers, airlines, pilots, airspace, regulators, airports and communities all have to work together.

Chicago Department of Aviation Report

  • April 2018 ANMS Report 
    Chicago Department of Aviation presented the April 2018 ANMS Report. The total number of aircraft operations for April was 73,515. Winds in April were predominantly from east (60%), which was reflected in the 60% easterly flow runway use. The most used departure runway was 9R (30%); the most used arrival runway was 10C (26%). Total complaints were 56,516. The CDA consultant noted that one of the loudest aircraft at the airport, the MD80, was in the process of being phased out. At one time, this aircraft represented 400-500 operations a day, it has declined to just 18 operations per day in April. View Report

  • Residential Sound Insulation Program
    Mr. Frame provided an update on the Residential Sound Insulation Program. Following a report issued by CDA in January regarding testing of odorous windows reported that no apparent health effects were found from odorous windows. The CDA is engaged in a series of efforts to identify a solution for those homeowners. They are conducting a second round of testing that includes laboratory and indoor air quality testing in an attempt to identify what individual component is causing the odor. A report on the second round of testing is expected later this month. The RSIP office continues to take requests from homeowners that call to request an odor inspection.

Report of the ONCC Chair—Mayor Arlene A. Juracek
Mayor Juracek announced the Executive Committee’s Strategic Planning Meeting will take place on August 16, 2018. Some items for discussion include:

  • Developing a work plan to better engage the school sound insulation committee and Federal legislators and the FAA, with a goal to reevaluate schools that were sound insulated 20 plus years ago and to look at schools in the new flight patterns resulting from OMP.
  • Devising the Fly Quiet process going forward as OMP nears completion.
  • Improvements to efforts to educate members and their communities, including innovative meeting formats and/or communication vehicles.
  • An understanding of future airfield arrival and departure patterns at full OMP build-out.

  • Fly Quiet Committee Update
    The first Fly Quiet Committee meeting will be held on Tuesday, June 19 at 9:30 a.m. at the Chicago Department of Aviation Building Conference Room 1 on the second floor. The goal of the first meeting is to review and discuss the committee’s work plan. The objective of the committee is to have members gain a better understanding of airport operations so we can review and revise a Fly Quiet proposal within 18 months for the post OMP full build out. Attendance will be key because of the complicated issues the committee will be working on during the coming months. Committee members should designate an alternate to represent his or her community.

Report of the Executive Director
Ms. Camacho stated that spots remain for the Airport & Noise 101 Workshop that will be held on June 15, 2018. Members who are interested in attending should contact Jeanette.

The next ONCC meeting will be held on September 7, 2018.
