Systems engineering for the 777 Autopilot Flight Director System

Abstract

This paper will describe the systems engineering process used in developing the 777 Autopilot Flight Director System (AFDS). It will include discussions regarding requirements capture, requirements allocation to hardware and software, system architecture considerations (including the architectural impact of safety requirements), change management, requirements and verification traceability, and requirements based verification. Additionally, the organizational structure employed and its interaction with the systems engineering process will also be reviewed. Finally, the results from a recent joint (Boeing and Collins) lessons learned exercise will be summarized.
