Expert System Applications to the Cockpit of the '90s

There is a strong requirement for a new generation of avionics systems with a more integrated hardware and software structure. This integrated avionics system will use significant increases in computer automation with more innovative signal processing, sensor fusion and expert system software to reduce pilot workload, while improving total system performance and reliability. Expert system software packages will be implemented within the core architecture of these next generation integrated avionics systems to assist the pilot. The expert systems will consider the pertinent information available from the ``sensor' subsystems to assess the current situation. The expert systems then consult their knowledge base and rule base software structures to determine alternative reactions to the perceived situation. Then pending upon the critical of the function, situation and reaction, the expert system could either execute the most favorable reaction or display the suggested alternative courses of action to the pilot. This paper addresses the requirement, the enabling technologies and the potential structure of this next generation of avionics. It concludes with two examples of the potential of future avionics expert systems. The two examples are 1) A Navigation and Route Planning Expert and 2) A Threat Assessment and Threat Reaction Expert. Significant things are happening in technology at an accelerating pace that enable the development of this new generation of avionics.

High-speed avionic optical fiber CDMA networks

With applications of systems integration technology to advanced aircrafts, high-speed and high-capacity optical fiber communication networks should be employed to support airborne broadband communication services. To guarantee real-time multiuser communications over a network, the selection of medium-access schemes is critical for avionics applications. In this paper, we briefly discuss the issues on high-speed multiple-access techniques and their applicability. Then we focus on the design and operation aspects of avionic optical fiber code-division multiple access (CDMA) networks. Some practical considerations on implementing such a CDMA network are also addressed and further improvement is pointed out. It is shown that avionic optical fiber CDMA networks can find a use in real-time avionic sensor data distribution, data exchange, and computer interconnects     

Integrated Avionics: Watershed in Systems Development

For aeronautical weapon systems now entering development, avionics will equal or surpass airframe, propulsion, and weapons in establishing system effectiveness, both in terms of mission accomplishment and in terms of reliability, availability, supportability, and life cycle cost. Emerging technologies created the opportunity to satisfy demanding operational needs and to provide the means to upgrade systems against an evolving threat. This requires, however, basic changes in the skills, design methods, and constraints applied to avionics development. This paper highlights trends in avionics technology and systems and suggests some of the new ground rules which must be imposed to realize their full potential. Avionics considerations must be a central element of system development from the very outset, and the process of conceptual planning and program estimation must take the new realities of avionics into account.
