Abstract:Modeling and simulation is often used to study
the physical world when observation may not be
practical. The overall goal of a recent and ongoing
simulation tool project has been to provide a
documented, lifecycle-managed, multi-processor
capable, stochastic simulation capability enabling
analysis of procedures and equipment for aircraft
flight in the national airspace system (NAS). The
tool is a Monte Carlo-based computer simulation
program that contains the stochastic models of most
components of the NAS, including navigation aids,
surveillance systems, pilots, aircraft, air traffic
controllers, and weather. It is also combined with
discrete artifacts such as FAA database-supplied
runway sizes and configurations, and obstacles. In
addition, the tool possesses a fast-time airframetype-
specific kinematic aircraft model, a highperformance
random number generator, a precise
WGS-84-compliant elliptical earth model, and a
graphical user interface integrating worldwide
photo-realistic airport depictions and real-time
three-dimensional animation.
This paper presents an overview of the
software tool and its formulation, including
programming languages, environments, and other
development tools; selection, design, and
implementation of the mathematical models; and
reviews the verification and validation processes.
