“…In order to obtain an early picture of the target times of 4D-FMS approaches relative to 3D-FMS approaches, the label projection technique "ghosting" was used and extended for continuous decent approaches (CDA). Ghosting is the method of projecting an aircraft's label on a radar display on a different route in order to make it easier for the ATCOs to merge two routes at one waypoint [24]. The ghost position is located where, based on current performance, the aircraft would be if flying that route.…”

Growing political pressure and widespread social concerns about climate change are triggering a paradigm shift in the aviation sector. Projects with the target of reducing aviation’s CO2 emissions and their impact on climate change are being launched to improve currently used procedures. In this paper, a new coordination process between aircraft flight management systems (FMSs) and an arrival manager (AMAN) was investigated to enable fuel-efficient and more sustainable approaches. This coordination posed two major challenges. Firstly, current capacity-centred AMANs’ planning processes are not optimised towards fuel-efficient trajectories. To investigate the benefit of negotiated trajectories with fixed target times for waypoints and thresholds, the terminal manoeuvring area was redesigned for an independent parallel runway system. Secondly, the FMS-AMAN negotiation process plan the trajectories based on time, whereas air traffic controllers guide traffic based on distance. Three tactical assisting tools were implemented in an air traffic controller’s working position to enable a smooth transition from distance-based to time-based coordination and guidance. The whole concept was implemented and tested in real-time human-in-the-loop studies at DLR’s Air Traffic Validation Center. Results showed that the new airspace design and concept was feasible, and a reduction in flown distance was measured.

“…A ghost is a projection of an a/c onto another route, serving the function of a placeholder for the real a/c. Ghosting assistance systems have been utilized to support converging runways operations, for instance (Mundra et al, 2003). Furthermore, it has been reported that ghosting aids for merging operations on arrival routes enable controllers to develop early situation awareness (MacWilliams & Porter, 2007).…”

Innovative concepts for fuel-efficient and noise-reduced air traffic suggest a better utilization of modern aircraft capabilities, like time-based planning of continuous descent approaches (CDA). One challenge of such concepts is the integration of aircraft flying CDA approaches and conventional air traffic. In this study, we examined the effects of different levels of automation provided by four different variants of visual aids on performance, information acquisition, resultant situation awareness, and workload with N = 78 students in a complex and dynamic microworld setting. While visual assistance had a positive effect on performance, attention was deviated from real aircraft. Nevertheless, attention deviation did not negatively affect conflict detection when assistance was activated manually. Moreover, anticipation of future losses of separation was improved by visual aids.

“…The idea of ghosting itself is not entirely new, different ghosting variants have been considered and employed e.g. at Amsterdam Schiphol [7] and Chicago O'Hare [8], mainly to support converging runway operations. Also, some qualitative results on controller feedback have been reported (e.g.…”

Within the German Aerospace Center (DLR) project FAGI (Future Air Ground Integration), new operational concepts and automation support systems for fuel-and noise-efficient arrival management are being developed. An essential element of the FAGI concept is a modified airspace and route structure, featuring the late merging of different arrival routes to support user-preferred flight profiles such as Continuous Descent Approaches (CDA). The present paper studies aircraft ghosting solutions on the radar display as a potential means to support controllers with merging different streams of aircraft with sufficient precision. In addition to a technical presentation of different ghosting principles, the results of two human in the loop studies are reported. Using objective and subjective data on performance, workload, situation awareness, and eye-tracking analysis, the benefits, trade-offs and acceptance of the visual assistance functions are discussed.
