P.; Kalaver, S. A.; Jadhav, A.; Holl, D. M.; Bea, R. C.; Gilgur, A. Z. <br/> <br/>Abstract: This paper presents the viewpoint that an air traffic management system is emergent, i.e., exhibiting behaviors at the system-wide level that emerge from the combined actions of individuals within the system. Emergence carries with it the additional implication that these phenomena typically cannot be predicted by examining the individuals' behavior alone. As a result, this paper proposes agent-based simulation as a method of predicting the impact of revolutionary changes to an air transportation system. Agent based simulation can integrate cognitive models of human performance, physical models of technology behavior and description of their operating environment. Simulation of these individual models acting together can predict the result of completely new transformations in procedures and technologies. While agent-based simulations cannot include every aspect of system behavior, they can provide quick, cost-effective insights that can supplement other forms of analysis. <br/> <br/>Description: Presented at the 6th USA/Europe Air Traffic Management Research and Development (ATM R&D) Seminar, 27-30 June 2005, in Baltimore, Maryland.

Yet, the role of airline operations personnel has not been well studied. This paper presents the findings of a series of ethnographic studies examining the work of airline Operational Managers (OMs) across several major and regional airlines. The role of airline OMs, and the information and tools they use to solve problems and maintain the airline's published schedule are discussed. Additionally, several work models developed as a result of the ethnography are presented and discussed. The work models include an information flow model, cultural model, artifact models, and sequence models. Implications are presented and discussed which transcend airline operations and are applicable to command and control more generally. <br/> <br/>Description: Presented at the 14th International Symposium on Aviation Psychology, Dayton, Ohio, 2007.

In a two-part experiment, participants performed airline rescheduling tasks. The first portion varied task time limits, the second introduced a sudden change in the task. Participants reported operating in, and transitioning between, different contextual control modes in response to time limits and task changes. Computer interaction did not correlate to contextual control modes. Contextual control modes did not correlate with TLX ratings of demand and effort, but did correlate with TLX-frustration and TLX-performance ratings. The results suggest that decision making performance may be determined by use of context-appropriate contextual control modes, and imply that the design of decision aids should work to support those modes. <br/> <br/>Description: Presented at the 13th International Symposium on Aviation Psychology, Oklahoma City, OK, 2005.
