One issue that regularly occurs in the context of ecological information systems is that these systems can invite operators to migrate to the limits of system performance. This could lead to the assumption that ecological systems are thus inherently unsafe. We argue, however, that the source of this issue is tied to a modeling problem of the work domain. That is, the majority of ecological systems predominantly model the physical or causal structure of the work domain, thereby neglecting the intentional structure. Many complex systems contain a mix of physical and intentional (i.e., rules, procedures, and regulations) that contribute to safe operations of those systems. The work described in this paper examines how visualizing intentional information in an ecological synthetic vision display affects pilot behavior, decision-making, and safety in a terrain avoidance task. An experiment with 16 professional pilots showed that adding an intentional constraint increases the clearance during terrain avoidance and gives them more insight into the terrain avoidance task enabling them to make better decisions.
