A pressing concern in modern fighter aircraft cockpit design is how to present and reduce large amounts of information obtained from several sensor observations of the same object. Currently, sensor observations are presented individually as overlays or in different displays requiring the pilot to control each sensor and integrate observations. The increased number of sensors and communication networks covering extensive ranges has, however, led to an unacceptable situation that hampers pilots' situation awareness and decision-making. Therefore, some from of automatic information management is necessary to support the pilot. Although considerable technological research has been conducted on automatic sensor fusion and management of multisensor and multisource tracking systems, only little is known about how to integrate systems capabilities with pilots' decision-making. This paper focuses on the factors involved in the pilots' control of multisensor and multisource systems for tracking, classifying, and identifying objects, which are presented on the tactical indicator in the cockpit of fighter aircraft during air-to-air situations. A conceptual model is presented based on systems characteristics and on a review of factors likely to be important. The model shows that for an appropriate function allocation, it is important to consider how pilots minimize goal trees for efficient decision-making and the strategies used for reducing uncertainties. Finally, suggestions are given for future research on multisensor and multisource tracking systems adapted to pilots' decision-making.
