Abstract : The current rapid increase in avionic system complexity causes difficulties in both defining and implementing the system requirement. Errors in the requirement and in the implementation of the requirement lead inevitably to an extension in the time necessary for system development and consequently to an increase in the cost of the developed system. This paper describes the avionic system onboard the Experimental Aircraft Programme (EAP) and the design process used on that system. In particular the effectiveness of: (a) rapid prototyping as a means to arrive at a sensible requirement; and (b) implementation, via Semi Automated Functional Requirement Analysis (SAFRA), is outlined. A resume of the results from the EAP is used to show that this structured approach is to be designed using both rapid prototyping and SAFRA, does reduce the time required for avionic system development.
