In the future fighter combat environment, the pilot will be faced with increased workload as he is forced to integrate various on-board sensor, weapons, and other aircraft systems. Specifically, he has less time to react to incoming missiles because of increased missile and aircraft speeds. The Air Force's Threat Expert Analysis System (TEAS) will determine and recommend threat responses to the pilot using all available resources. The system will do much of the data integration for the pilot, thereby reducing his workload. This paper reviews the approach being taken in the TEAS program development.
