DISTRIBUTION CODE This report is part of the INM 7.0 software release. 13. ABSTRACT (Maximum 200 words) The Federal Aviation Administration, Office of Environment and Energy, Noise Division (AEE-100) has developed Version 7.0 of the Integrated Noise Model (INM) with support from the ATAC Corporation and the Department of Transportation Volpe National Transportation Systems Center. 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, FAR Part 161 approval of airport noise restrictions, and for environmental assessments and environmental impact statements under the current version of FAA Order 1050.1E. New features in INM 7.0 include: lateral attenuation calculations based on SAE-AIR-5662; flight path segmentation, flight procedure step types, bank angle calculations, and thrust reverser implementation based on ECAC Doc 29; helicopter modeling methods based on Version 2.2 of FAA’s Heliport Noise Model (HNM); an HNM study import function; a scenario annualization function allowing operations to be adjusted after performing a run; a multi-threaded run mode; fixed-spacing contour grid functionality; increased differentiation between different type of aircraft (civil, military, and helicopter); the ability to input location values in lat/long or X/Y; and many extended database fields. INM Version 7.0 software runs on PCs using a minimum hardware configuration of a Pentium III processor, Microsoft Windows 2000 or XP operating systems, 1.0-Gb RAM, mouse input device, hard disk drive, and CD-ROM drive. 14.

INM 7.0 User’s Guide PREFACE The FAA Office of Environment and Energy supports the assessment of aircraft noise impacts by developing and maintaining noise-evaluation models and methodologies. 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 model available to hundreds of U.S. and international users. Domestic use of the model includes FAR Part 150 and 161 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 microcomputer environment. In Version 5, INM was rewritten to 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. In Version 6, INM acoustic modeling capabilities were enhanced by the introduction of average noise spectra. In Version 7, INM acoustic and flight performance modeling capabilities are again enhanced to stay consistent with evolving best practices and a helicopter noise modeling capability is added. The INM model is developed and maintained by: • FAA Office of Environment and Energy (AEE-100) – project management • ATAC Corporation – system integration, user interface, and flight model. • Volpe National Transportation Systems Center (VNTSC) – noise model The FAA formed a Design Review Group (DRG) as a technical advisory group of government and private sector experts in the fields of aviation, acoustics, and computer modeling. The DRG guides the FAA in INM and other noise model development. The DRG reviews functional designs and recommends how to effectively implement designs to meet FAA and industry user requirements. The DRG consists of the INM development team (AEE-100, ATAC, and VNTSC), representatives from various FAA offices, other Federal agencies, airport authorities, industry, and international organizations: Federal Aviation Administration: • Office of Environment and Energy, Noise Division (AEE-100) • Office of Systems Capacity & Requirements, Airspace Capacity Planning (ASC-200) • Office of Airspace Management, Environmental Programs (ATA-300) • Office of System Architecture & Program Evaluation, Program Analysis & Operations Research, Technology (ASD-430) • Office of Airport Planning/Programming, Community/Environmental Needs (APP-600) • Eastern Region (AEA-530), Jamaica, NY i INM 7.0 User’s Guide 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 • Volpe National Transportation Systems Center, Cambridge, MA Corporations: • ATAC Corporation, Sunnyvale, CA • Boeing Commercial Airplane Group, Seattle, WA • Bolt Beranek & Newman Inc., Systems & Technologies, Canoga Park, CA • Eldred Engineering Inc., East Boothbay, ME • Harris Miller Miller & Hanson Inc., Burlington, MA • Howard Needles Tammen & Bergendoff Inc., Alexandria, VA • Landrum & Brown Inc., Lawrence, KS • Leigh Fisher Associates Inc., San Mateo, CA • LeTech Inc., Alexandria, VA • Metron Inc., Reston, VA • Ricondo & Associates, San Francisco, CA • SAIC Inc., Falls Church, VA • URS Greiner Engineering Sciences, Tampa, FL • Wyle Laboratories Inc., Arlington, VA International: • DELTA Acoustics & Vibration, Lyngby, DENMARK • SINTEF DELAB, Trondheim, NORWAY ii INM 7.0 User’s Guide ACKNOWLEDGMENTS Many people helped make INM Version 7.0 possible.
