  • Abstract:
    The John A. Volpe National Transportation Systems Center (Volpe Center), in support of the Federal Aviation Administration, Office of Environment and Energy, has developed Version 2.2 of the Heliport Noise Model (HNM). The HNM is a computer program used for determining the impact of helicopter noise in the vicinity of terminal operations. This document, prepared by the Volpe Center's Acoustics Facility, is a User's Guide for HNM Version 2.2. It presents: (1) computer system requirements and installation procedures; (2) an overview of HNM capabilities and the user's implementation of these capabilities; (3) the elements of a heliport case study; (4) a step-by-step tutorial for preparing and running a case study; and (5) the interpretation of HNM Version 2.2 output. Also presented, in the Appendices of this document, are the following: (1) a discussion of the technical revisions made to several internal algorithms - primarily revisions which are transparent to HNM users; (2) a discussion of the helicopter noise Data Base used by the HNM; and (3) a summary of error messages in the HNM.
