Trajectory-based operations (TBO) are at the forefront of the Next Generation Air Traffic Management System (NextGen). The vision of NextGen is one in which pilots will be responsible for following 4-dimensional (4D) trajectories while maintaining separation from other aircraft and weather. Ongoing research focuses heavily on the infrastructure and procedures required to conduct 4D TBO; however, new flight deck displays are going to be needed to support pilots who will be faced with the challenge of making more complex, strategic decisions than are required in current-day operations. In response to this challenge, Aptima proposes to develop a Trajectory-Based Operations Adaptive Information Display (TBO-AID). TBO-AID will incorporate innovative display techniques that address the (1) unique information needs associated with conducting 4D operations (e.g., crossing a specific navigation fix at a specific time); (2) uncertainty and risk associated with weather and mixed-equipage conditions, key challenges for conducting 4D TBO; (3) potential advantages gained through multimodal information presentation; and (4) need for model-based, situationally aware display adaptation to support information processing and decision making. Anticipated results of commercializing this effort include increasing the safety and efficiency of air traffic and expanding the maximum number of aircraft potentially in flight at a given time.
