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

Abstract

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 effi...
