ABSTRACT (Maximum 200 words) The Federal Aviation Administration, Office of Environment and Energy (AEE-120) has developed Version 5.0 of the Integrated Noise Model (INM) with support from the ATAC Corporation, the U.S. Department of Transportation John A. Volpe National Transportation Systems Center, and LeTech Incorporated. The FAA Integrated Noise Model is widely used by the civilian aviation community for evaluating aircraft noise impacts in the vicinity of airports. The model is typically used in the U.S. for FAR Part 150 noise compatibility planning and FAA Order 1050 environmental assessments and environmental impact statements. Major enhancements to INM Version 5.0 include a new graphics user interface, new data preparation and data input aids, new graphics and plotting capabilities, and improved and faster noise calculation algorithms. There are many technical enhancements to the computer code which provide faster run times and more accurate noise predictions. INM Version 5.0 software runs on PCS using a minimum hardware configuration of a 486DX 66-MHZ processor, Microsoft7 Windows NTJ 3.5 or WindowsJ 3.1 operating systems, 32-Mb RAM (NT) or 16-Mb RAM (Windows), 640x480 16 colors VGA display, mouse input device, 3.5-inch 1.44 Mb floppy disk drive, 300-Mb hard disk drive, and CD-ROM (optional). 14.

In particular, the FAA's Integrated Noise Model (INM) is widely used by the civilian aviation community for evaluating aircraft noise impacts in the vicinity of airports. Since 1978, the FAA has made the INM available to hundreds of U.S. and international users. Domestic use of the model includes FAR Part 150 noise compatibility planning and FAA Order 1050 environmental assessments and impact statements. INM was originally designed for a batch-process mainframe-computer environment and evolved in the mid-1980s to the PC-DOS microcomputer environment. In Version 5.0, INM takes advantage of recent advances in computer hardware and software technology. Major enhancements include a new graphics user interface, enhanced data preparation and data input aids, new graphics and plotting capabilities, and improved and faster noise calculation algorithms. INM Version 5.0 runs on PCS using the WindowsJ or NTJ operating systems. The INM Development Team members and their main areas of responsibility are: FAA Office of Environment and Energy (AEE-120) -- project management ATAC Corporation -- system integration, user interface, and flight model John A. Volpe National Transportation Systems Center (VNTSC) -- noise model LeTech Incorporated -- interactive graphics and preprocessing. As part of the planning for Version 5.0, the FAA formed a noise modeling Design Review Group (DRG). The DRG is a technical advisory group of government and private sector experts in the fields of aviation, acoustics, and computer modeling who are guiding AEE-120 in noise model development. The DRG reviewed functional designs for Version 5.0 and recommended how to effectively implement these designs to meet FAA and industry user requirements. The DRG consists of INM Development Team Members (AEE-120, ATAC, VNTSC, LeTech), representatives from various FAA offices, other Federal agencies, airport authorities, industry, and international organizations. The 26 DRG members are listed below: Federal Aviation Administration, Washington, DC: Office of Environment and Energy, Analysis and Evaluation Branch (AEE-120) Offic e of Environment and Energy, Technology Division (AEE-100) Office of Environment and Energy, Environmental Planning (AEE-5) Office of Systems Capacity & Requirements, Airspace Capacity Planning (ASC-200) i INM USER=S GUIDE Office of Air Traffic System Management, Environmental Issues (ATM-700) Office of System Architecture & Program Evaluation, Program Analysis & Operations Research, Technology (ASD-430) Office of Airport Planning/Programming, Community/Environmental Needs (APP-600) Other Government: Armstrong Laboratory OEBN, Wright Patterson Air Force Base, OH MASSPORT, Noise Abatement Office, East Boston, MA Metropolitan Washington Airports Authority, Alexandria, VA NASA Langley Research Center, Acoustics Division, Hampton, VA U.S. Army Construction Engineering Research Lab, Champaign, IL John A.
