ABSTRACT
Within a wide range of operational situations, ATC Controllers are able to ensure safety while keeping efficiency and environmental impact in optimal balance. Especially in managing operational disturbances and unpredictable events, characterized by high complexity and dynamics, ATC Controller expertise is crucial (Redding, Ryder, Seamster, Purcell & Cannon, 1991; Schuver-van Blanken, Huisman & Roerdink, 2010). The high level of required ATC Controller expertise is primarily caused by the cognitive complexity that is inherent in managing disturbed ATC operation. Further, ATC Controller expertise is characterized by strategies to mitigate this cognitive complexity and to ensure safety and efficiency in day-to-day operational disturbances.
