Development of the Virtual Flight Deck (VFD) simulation environment

In the study of shipboard helicopter operations, simulations have been used in a variety of areas. Most of these simulations involve software implementation of mathematical models that run faster than real time to produce meaningful results over a long span of time. When human operators or in-service hardware is brought into the simulation, however, the realtime requirement becomes a central issue. The Virtual Flight Deck - Real-Time (VFD-RT) simulation environment is built as an extension to previously-developed mathematical models to meet this real-time requirement. The VFD-RT uses a centralized model to connect the components of the simulation and relies on the Microsoft Windows message system as a means of communication between the different parts of the environment. This paper discusses the development and some limitations of the VFD-RT environment.
