DSSA case study: navigation, guidance, and flight director design and development

The effort to create a workstation-based environment to support the development, maintenance and upgrade of avionics systems with an order-of-magnitude improvement in quality and productivity over current approaches through the reuse of large portions of well-designed and documented software is discussed. The challenges of capturing and representing knowledge for avionics navigation, guidance, and flight director are described to illustrate the impacts of designing a domain-specific software architecture. The technologies required to enable engineers to use domain knowledge effectively within a workstation-based development environment are also discussed
