Summary of Re-engineering of HCI of Mature CRCT Functionality for Technology Transfer

From 1999 to 2002, MITRE/CAASD conducted operational evaluations of Collaborative Routing Coordination Tools (CRCT) functions, with FAA Traffic Management personnel. Based partly on the evaluation results, the FAA deemed certain CRCT functions operationally mature, such as the Flow Constrained Area (FCA) and Reroute Modeling functionality. The need for integration of the FCA and Reroute Modeling capabilities, and the existing ETMS Create Reroute functionality, was also identified. In FY03, as part of the CRCT technology transfer process, CAASD worked with the FAA Technical Center and the Volpe Center on re-engineering the human-computer interface (HCI) of the CRCT functions. CAASD contributed to this effort by presenting evaluation results and integrated FCA-Reroute user interface mock-ups to FAA and industry stakeholders, and by refining the interfaces and concepts iteratively as FY03 progressed. Refinements were based on stakeholder feedback, and on cognitive modeling analysis using the Natural Language Goals, Operators, Methods, and Selection rules technique (NGOMSL). This analysis demonstrated a physical and mental workload benefit of integrating the FCA and Reroute Modeling functionality. CAASD presented and discussed the analysis results and refined interfaces and concepts at numerous design meetings during FY03. The ETMS designs developed following these activities represent steps toward the goal of further integrating FCA, Create Reroute, and Reroute Modeling.
