Data previously collected on existing aircraft operations for the 12-month period January 1, 2001 through December 31, 2001, used for the "Contour Update 2001" will be utilized for this analysis. No supplemental data will be collected. No radar data will be obtained. Task 1 Noise Evaluation of Existing Approaches to Runway 9 The team will assess the noise impact resulting from existing aircraft approach operations on Runway 09 at EYW using a systematic approach which relies on standard data included within the Integrated Noise Model (INM). The Team will conduct a noise sensitivity analysis using existing airport operations data in order to identify the three (3) most significant aircraft noise contributors conducting approaches to Runway 09 at EYW. The team will evaluate the existing noise exposure based the Yearly Day-Night Average Sound Level (DNL), as well as through the use of supplemental metrics (e.g., Time Above a Threshold, Number of Events Above a Threshold) and grid analysis. The team will identify the noise exposure resulting from the existing aircraft approach operations on Runway 09, and advise on feasible parameters for alternative approach procedures. Task 2 Noise Evaluation of Alternative Approaches The team will evaluate the noise benefits of up to four (4) alternative approach procedures for Runway 09 at Key West International using the Integrated Noise Model (INM) augmented through the use of custom noise analysis software. The team will evaluate the noise exposure of the alternative approach procedures based the Yearly Day-Night Average Sound Level (DNL), as well as through the use of supplemental metrics (e.g., Time Above a Threshold, Number of Events Above a Threshold) and grid analysis. The noise levels associated with the top three (3) aircraft noise contributors (identified in Task 1) will be calculated using each of the alternative approach procedures. These noise levels will be compared to the results of Task 1 and to each other to identify the quietest alternative with the least noise exposure to noise-sensitive land uses. When the major aircraft noise contributors are identified for existing conditions, the team will provide technical comparisons and formulate recommendations on noise exposure. APPROACH STUDY - REDUCED SCOPE Page 2 of 2 Task 3 Recommended Procedures The alternatives will be analyzed based on an evaluation of the improvements in noise exposure. One or more procedures may be recommended for consideration as appropriate, particularly if the results of the analysis do not show a clearly favored alternative, The client and stakeholders are most appropriate to weigh the tradeoffs. If appropriate, the recommended approach procedure(s) will be tested for a 30- day period. The public will be informed of the test, and asked to submit comments in writing or via the airport noise hotline. Task 4 Document Preparation A document will be prepared that describes the approach procedure(s). The document will also describe the results of the noise evaluation for each procedure, as well as the basis for the recommendations and conclusions. Task 4.1 Airport Review Document (Version 1) Version 1 of the document will be prepared and submitted to the airport staff for their review and comment. Five copies will be prepared (2 for the airport staff; 3 for the consultant). Task 4.2 Ad-Hoc Committee I FAA Review Document (Version 2) Version 2 of the document will incorporate the airport staff's comments and will be distributed to the Ad-Hoc Committee for review and comment. Version 2 will also be distributed to the FAA for review and comment. Thirty copies will be prepared (20 for the airport staff and Ad-Hoc Committee; 5 for FAA; 5 for the consultant). Task 5 Ad-Hoc Committee Meetings The Project Manager will report the progress of the study at the regularly scheduled Ad-Hoc Committee meetings. All public involvement opportunities will be through regularly scheduled Ad-Hoc Committee meetings. Task 6 Project Management This task involves the coordination and management of the non-technical aspects of the project. > C :J t- en en w a: :J c W o o a: c. :I: o <C o a: C.N C.O <Cc, ~~ ~I ~N 1:5-.... .~ .l!! .8 e~1ll ll. ...J - _c-lO~ 5i .2.!!! .,. 0 e13iij :3 .- ~"C~ tII o 0 0. .. .. cn:(/)~g i;iJ: (/)- - tII C)= 5'~ .- CII Co. ~(/) co'lii ..... 0 "'0 ..
