Pinch-and-pull with spatial-temporal energy trajectory: new display concept for in-flight energy management

摘要

Purpose - The purpose of this paper is to present a new visualization display based on a pinch-and-pull concept with 4D spatial-temporal energy trajectory (4DET), for energy profile management of air traffic, specifically in relation to air traffic control for use in the flight deck environments of the future. Design/methodology/approach - The energetic state of an aircraft may be specified by "fly-by parameters" which include speed, thrust, altitude, configuration, heading and even flight path; real-time knowledge of how such parameters complement or influence each other is essential for the successful execution of complex in-flight procedures. Here, the authors have conducted interviews with pilots and pilot trainers using the cognitive task analysis technique, from which the scope was identified for improving current flight management systems. In particular, pilots reflected a desire for a more innovative means of energy management that strives to utilize and present available flight data in a more efficient, readily-accessible manner. In response to these concerns the authors propose a novel on-board visualization display concept for energy management, which goes beyond traditional confines of defining trajectories in space and time. Findings - Expanding the concept of a 4D spatial-temporal trajectory (4DT) to include the notion of energy, hereafter referred to as the 4DET, automated, real-time, calculations of energy requirements can be incorporated within intuitive, user-interfaced, 3D visualisation displays. Practical implications - An intuitive algorithm and display concept expected to help future ATCOs and pilots with more interactive and reliable control of aircraft energy dissipation in an era of increased information overload. This may be particularly relevant for dealing with stressful flight scenarios such as take-offs and landings, ultimately improving arrival-time accuracy and airport efficiency. Originality/value - Through this 4DET concept the paper unveils an innovative method for improving transport punctuality and flight safety, which in particular may be applicable for future European air traffic management initiatives, in keeping with the general projected trend of increasing air traffic in the skies.
