The Noise Data Acquisition and Display System (NDADS) is an interactive tool for the user-enhanced automation and
creation of flight tracks and profiles for noise analysis based on radar tracking data. The NDADS system features graphical
methods for the rapid creation of vectored flight tracks with statistical guidance via gate penetrations and visual references
based on background maps. Profiles, including altitude, velocity, and power, critical for the evaluation of noise contours, may
also be generated easily. NDADS generates files which may be read directly into the NMAP Noise Analysis system. This
document describes the NDADS Version 3, which supports NMAP 5 and NMAP 7 formats, and instructs the user towards the
development of aircraft flight tracks and profiles.

The collaborative work of Hughes Associates, Inc. (HAI), the Naval Research Laboratory (NRL), and a group at
Mississippi State University resulted in developing a simulation system including Graphical User Interface (GUI) and
visualization. The simulation environment provides a runtime environment for a third-party simulation package currently
FSSIM developed by HAI. This user’s manual for the viewer provides documentation of the GUI layout and detailed
discussion of features of the output display.

Several computational tools exist for examining fire effects that can be applied to a ship and its crew. Hand calculations
can be used to examine simple scenarios in single compartments. Zone models are also suitable for more complex,
time-dependent scenarios involving multiple compartments and levels, but stability can be a problem for multilevel scenarios,
scenarios with Heating, Ventilation, and Air Conditioning (HVAC) systems, and for post-flashover conditions. Computational
fluid dynamics (CFD) models can yield detailed information about temperatures, heat fluxes, and species concentrations;
however, the time penalty of this approach currently makes using CFD unfeasible for long periods of real time or large
computational domains. Another class of models has traditionally played supporting roles in fire modeling. This class is
constituted by a variety of network models, which are used for ventilation systems in buildings or fluid flow in piping
networks. These models lack specific physics required for fire modeling. Therefore, to meet the computational speed and
algorithm requirements, it was decided to develop Fire and Smoke Simulator (FSSIM) as a network fire model. This document
(User’s Guide) discusses creation of FSSIM input files, including guidance in transforming a prototype structure to a network
representation, and explains the available outputs.
