Air traffic complexity in future Air Traffic Management systems
Journal of Aerospace Operations, 2012 In this paper we study the issue of characterizing the complexity of air traffic to support Air Traffic Management (ATM) operations. We discuss, in particular, the features of a complexity metric that are relevant for application to future ATM systems where part of the responsibility for separation assurance and trajectory management operations is ...

Air traffic control activity increases attention capacity in air traffic controllers
Dementia & Neuropsychologia, 2010 Abstract Air traffic controllers simultaneously develop complex and multiple tasks in the course of their activities. In this context, concern is raised over the high level of attention needed by these professionals which can ultimately be affected by stress and fatigue.
