This report describes a literature review of automation as a basis for development of coming Swedish fighter aircraft. Automation has been developed for a long time to perform tasks faster, more efficient, and safer than what is possible manually. The literature review shows that the view on operators' interaction with automation has evolved over the years to accommodate new requirements and technical capabilities. Automation has historically been categorised by how much of the tasks are performed by the automation respectively the operator, but this categorisation is too static for many current systems and tasks. Instead, the operator and automation perform tasks interactively and cooperatively. Operators therefore need to (1) understand how functions are automated (observability), (2) understand how the automation will perform in anticipated situations (predictability), and (3) opportunity to change the task allocation and goal orientation (directability). Further, the literature review describes how automation characteristics affects operator trust, mental workload, and situation awareness. Finally, there is discussion about how future development of automation may use the model Data Fusion Information Group.
