Traffic Managers, Supervisors and Air Traffic Control System Command Center (ATCSCC) Specialists have a critical and significant responsibility in the ATM system to deal with widely varying contingencies and issues. Although many tools exist to support the Traffic Manager in fulfilling their duties, these tools generally focus on one specific type of traffic management initiative and the planning and decisions suggested by these tools are not integrated together. While much attention has been focused on decision support tools and information systems for the controllers, only minimal attention has been given to decision support tools for the Supervisors and Traffic Managers other than the specific traffic management initiatives. We propose to develop a Course of Action Planner for Air Traffic Coordinators. Given assumed inputs from all systems that may affect the Coordinator's tasks (via SWIM), the planner will develop a set of required and prioritized tasks, and feasible options for solutions to the identified issues. Each option will contain a list of actions (including TMIs) that, when combined, will address the identified situation.
