Digital Avionics Information System (DAIS). Volume I. Impact of DAIS Concept on Life Cycle Cost.

Abstract

The Digital Avionics Information System (DAIS) approach to avionics design is a total system concept rather than a functional subsystem or hardware-oriented system. DAIS uses common processing, information transfer, control and display, and support software elements to service all avionics functional areas on an integrated basis. Thus, the DAIS architecture and core elements are not dedicated to any one specific avionic function, but are used to perform the tasks of many avionic functions with the avionic sensors and subsystems. This systems approach provides flexibility to accommodate a wide variety of avionic configurations and missions, as well as redundancy to improve availability. Standardization and replication of the core elements can reduce the life cycle costs when major modifications/retrofits of an avionic configuration are considered, or when applied across the fleet by reducing unnecessary development proliferation and reducing maintenance costs.
