Operations Concept for the TCCC Man-Machine Interface analyzes the tower Air Traffic Controller's job in the Tower Control Computer Complex (TCCC) environment. It considers the operations in today's towers and the automated capabilities planned for the TCCC, to reach an understanding of the Controller's job after TCCC implementation. Three separate positions are analyzed: Local Control, Ground Control, and Clearance Delivery/Flight Data. Analysis results include composition graphs and narratives showing the logical flow through the sub-activities of the three positions; task analysis, presenting the tasks of each position; task characterizations, including information requirements, cognitive/sensory attributes, and performance criteria associated with each task; and a top-level dialogue description summarizing the interaction between controller and TCCC. Traceability between tasks and system level specification requirements is also provided.

This text discusses the skills and abilities that air-traffic controllers need. Its approach is international as air-traffic control practices throughout the world have to be mutually compatible and agreed.
