This paper presents an approach to pilots’ situation awareness (SA) that focuses on temporal issues. This approach must be complemented by other factors such as spatial awareness. The temporal aspects of SA are important for the flying task, for computer interaction, and for human communication. The presence of these three domains together inside the cockpit leads to difficulties with time management. Temporal aspects in human-computer interaction (HCI) are investigated in the context of aviation SA. Useful tools for their evaluation and anticipation are proposed. Finally, psychological, cognitive and philosophical studies on time consciousness that enable the investigation of relevant attributes of complex dynamic systems such as aircrafts are presented.
