Human factors issues in advanced moving-map systems

Vector-based maps are an advanced capability of digital moving-map systems that are easily customised and can be powerful aids to aircrew information processing and decisionmaking. However, they may place excessive demands on an aircrew's information processing requirements, cause an increase in wor kload, and degrade situational awareness if the user interface is not desig ned properly. There is little information available about the human factors and situational awareness issues relevant to vector-based maps. In this pa per, we summarise relevant research on human factors and situational awaren ess aspects of using vector-based maps, identify key issues, and recommend directions for future research.
