Debriefing is a crucial aspect of pilot training. To enhance the effectiveness of fighter pilot training, TNO Defence, Security and Safety and the Royal Netherlands Air Force (RNLAF) have developed various novel debriefing concepts. In typical mission debriefings, large amounts of data are recorded, often from different sources such as on-board systems and sensors. However, the available time for processing and debriefing this information and relating it to mission-specific or user-specific learning objectives is limited. This provides challenges for data integration, synchronization and presentation, and requires solutions to provide users with the right information at the right time in the right format. Instead of replicating information in exactly the same manner as presented in on-board systems we propose alternate information modes which provide operational users with additional cues. In this paper we discuss the results of our work on IDEFIX, our innovative debriefing environment. Together with operators we developed a number of solutions for presenting information in an adaptive, user-centric and mission-specific manner. IDEFIX has a dynamic Graphical User Interface that allows the user to customize the debriefing environment. Mission type specific parameters and objectives are used as input to control the presentation of information into different views and panels. A new agent-controlled, context-dependent 3d-view was created to enhance situational awareness and to gain insight into fighter jet movements, threats and weapons impact. IDEFIX proves to be a useful environment for testing integral plan/brief/debrief capabilities, which will be the focus of our future research.
