Avionics Development and Integration System Methods

This paper describes a set of life cycle methods that were developed in 1980 and 1981 and used in the later phases of the 757/767 airplane programs. They have been used as a framework to establish and guide the introduction of a wide use of similar methods for the future avionics of Boeing´s next airplane, the 7J7. The methods were designed to improve communication of the system´s requirements, architecture and implementation to a wide group of interested parties ?? not just the development engineers but also the users, maintainers, customers and support organizations. A major aspect of these methods is that they were designed to be used for systems in general not just software systems. This paper will describe the background and goals and objectives leading to the need for systems engineering methods, describe the methods and give an example of their use. It will conclude with remarks on steps taken to introduce methods of this type on a wide scale to support the next Boeing airplane.
