A Methodology for Identifying Information Requirements and Interaction Issues for an HSCT Autoflight System

This purpose of this research is to identify the information requirements and interaction issues associated with pilot use of an autoflight system for the high-speed civil transport (HSCT). The approach taken was to survey and evaluate existing research tools and methods for representing and understanding human interaction with complex engineering systems, to model a current-generation autoflight system representative of the capability required in the HSCT using the techniques found to be most appropriate, and then to use this model and other proposed HSCT guidance and control concepts to identify the necessary information requirements and interaction issues. The modeling representation chosen was the Operator Function Model (OFM).
