This paper presents a summary of the findings of AGARD Working Group 06. This working group was established to consider Distributed Micro Processor Application to Guidance Control Systems. The results of this Study are presented in AGARD AR-178. One of the areas considered by the working group was option and opportunities for standards and it is this area that is being considered in this paper. It should be emphasised that this document is not intended to suggest definitive standards or even to state categorically that any given standard should be developed. Rather its intention is to focus attention upon the need for standards and to point out areas where opportunities exist for standardization. As will be seen from the previous sections in this report there is a vast proliferation in hardware and software. When systems are developed they often produce unique hardware and software, such as operating systems, executives, high level languages, etc. Since the life cycle of aircraft systems is at least twenty years from conception, it could be as much as thirty years after the initial design before the systems are finally phased out. This makes it almost impossible to maintain avionic systems in the later parts of their life cycle.
