Core avionics domain analysis

The authors outline the process, challenges, and preliminary results of performing a domain analysis for the avionics functions of navigation, guidance, and flight director-essential, real-time features of integrated avionics systems. They describe the relationships between the components of the architecture and the principles behind the architecture´s organization. In particular, they present a first-level look at the preliminary design of the navigation component. The goal of the research discussed is to use domain analysis to engineer an architecture and associated components that allow the rapid development of requirements and software for avionics functions. Another aim is to overcome some of the shortcomings in software reuse and computer aided software engineering (CASE) for avionics software development. This research aims to free the software and system designers from the routine aspects of avionics development, thus giving them time to concentrate on engineering the best solution for their customers
