52 Aircraft Noise: A Toolkit for Managing Community Expectations Large Airport - (109) Gatwick Airport: Interactive Aircraft Noise Website. The purpose of the BAA's Gatwick Airport website is to provide the public useful and clear information about the aircraft noise they are hear- ing and why it occurs. This website's purpose is to explain some of the issues about airplane noise, answer the most common questions, and describe what the airport is doing about it. 4-125 By using the website links, users can find information about areas where they live or work and understand how departing and arriving aircraft can affect them. The interactive website is exten- sive, informative, and user-friendly with many pages dedicated to communicating the effects of aircraft noise, education, and the airport's role in the community. Additionally, documents, leaflets and reports are available for download. The interactive aircraft noise website is accessed from the Gatwick Airport home page. The home page is well designed and highly graphic; it includes windows and pull-down menus for navigation to the noise website. The home page for the website also is well designed, inviting, and includes navigation windows to more detailed sections. These include "Noise Explained" which provides educational information for the layperson, and "Noise In Your Area" which provides the public interactive on-line flight tracking and identification system access. The Noise Explained section includes a detailed page on the Causes of Aircraft Noise which includes a range of topics, from what causes aircraft noise, to living close to the airport, under the flight path, under the approach path, living under a holding stack or between the holding stack and airport, noise around the airport, and what the airport is doing about it. Bothered by Aircraft Noise? We're Listening. This on-line booklet sets out to explain some of the issues about airplane noise, answer the most common questions, and sets out what Gatwick is doing about it including: what is the problem, how big is the problem, what they have done about it, and further information. The Causes of Aircraft Noise page includes an interactive diagram of an airframe and demon- strates how noise is generated as air passes over the plane's body fuselage and its wings. It shows aircraft with their flaps down and up, with illustrative text to explain the effects in each configuration. Under the flight path provides interactive diagrams of wind direction and the consequences of living or working under a flight path and hearing planes taking off. Living under a holding stack provides an interactive diagram of a plane flying in a holding stack pattern and explains what you hear while they are waiting to make final approaches. Noise around the airport explains why and how noise around the airport is measured. A noise exposure contour map with information related to the distribution of noise in neighboring communities for the area around Gatwick is provided. Better Technology uses charts and interactive diagrams to show how much quieter each new generation of aircraft has been than the one that preceded it. Improving operations uses an interactive diagram to show a continuous descent approach procedure, non-continuous descent approach, and both profiles. The Noise In Your Area section includes Where Do You Live and Tracking Flights. By using an on-line tracking tool, users can see where aircraft are flying in relation to where they live or work. Webtrak is available to plot postal code location and replay a selected period of Gatwick flights. A series of file attachments which provide greater detail about aircraft operations at Gatwick can be found in this section of the website. Interactive Learning Tool Description. Public decision-making processes at every level of independent agency or gov- ernment are being transformed by new methods and new technologies for citizen participation.

Community Engagement Strategies and Techniques 53 Finding the right tool for the task at hand is the key to success. For example, engagement tools can provide focused feedback from stakeholders through on-line deliberation, webcast meetings, stake- holder dialogues, community conversations, research or keypad polling. Lessons for Airport Managers. Today's public is aware of and often expect the use of technical advances that make it possi- ble to participate or provide comment on a project or study. The right tool can provide focused feedback from stakeholders, help an organization increase meeting effectiveness, and promote participation through application of state-of-the-art technology. Example Best Practices. The following interactive learning tools were chosen as best prac- tice examples: FHWA's Noise Compatible Land Use Planning Workshops (110) FHWA sponsored a series of workshops in 2005 at strategic locations around the country to describe the merits of noise compatible planning along roadways. Specifically, the workshops were designed to: Educate and increase the use of noise compatible land use strategies by communities; Build the resources (video, reports, course curriculum) to better educate communi- ties; and Lead to less frequent utilization of noise barriers. The half-day workshop began with a plenary session, which provided an overview of noise compatible land use planning, the status of local activities, and examples of implementation of noise compatible land use strategies from around the country. Participants then separated into breakout sessions to discuss application of the noise compatible principles for their commu- nity. The workshop showed land use planners and elected officials how they can influence neighborhoods affected by highway noise by utilizing local ordinances and zoning tools. Open- space techniques that greatly reduce interior noise penetration include buffer zones between the roadway and the development, possibly focusing garages and rear yards adjacent to the roadway, and providing landscaping and recreational features such as earthen berms or recre- ational trails. Similar techniques may be used in judicious subdivision designs based on aircraft ground noise patterns. From these workshops, a proceedings document (111) 4-126 was developed summa- rizing the workshops, and a curriculum (112) 4-127 was developed, which can be used to teach the basic concepts of compatibility planning by any party interested in educating management, developers, planners, decision-makers or students on noise issues. The program is supported by an extensive PowerPoint (113) presentation. 4-128 America Speaks 22nd Century Town Meetings (114) This is a public forum that links technology with small-group, face-to-face dialogue to allow thousands of people to deliberate simultaneously about complex public policy issues and express a shared message to decision makers. The drop down boxes under "Services" on the home page lead to a variety of useful tools and capabilities for engaging the public. Hartsfield-Jackson Atlanta International Airport. Hartsfield-Jackson Kids webpage. (115) 4-129 The Hartsfield-Jackson Kids page provides information on noise and air quality issues written for young people. Kids of all ages are invited to become a part of the Hartsfield-Jackson Atlanta
