“…It superimposes a red line around the obstacle in the HUD, at a distance of 10 feet, the minimum clearance, see Figure 2. Its concept is based on systems described by Münsterer et al [8], which draw warning contours around dangerous obstacles like windmills. Its detection distance is set to 300 meters, and kept constant between the two visibility conditions.…”

“…Flying in a Degraded Visual Environment decreases the Usable Cue Environment (UCE)-Level, which in turn leads to a decrease in Handling Qualities [6]. Head-Up Display technology has been applied successfully to increase the UCE-level by supplying the pilot with an additional perspective overlay based on data recorded by on-board sensor suits and/or offline maps [7,8].…”

“…In this case, the outside view was distracting the pilot from the two-dimensional cue-following task. Current concepts of obstacle avoidance systems provide maneuvering advice [10], increase the perception of obstacles by magnifying them visually [8,11], or provide combined visual/auditory cues [12].…”

This paper aims to reveal the effect of different display design principles in the helicopter domain. Two different obstacle avoidance support displays are evaluated during low-altitude, forward helicopter flight: a baseline Head-Up Display (HUD) is complemented either by a conventional advisory display, or a constraint-based display inspired by Ecological Interface Design. The latter has only been sparsely applied in the helicopter domain. It is hypothesized that the advisory display reduces workload, increases situation awareness, and improves performance measures in nominal obstacle avoidance situations, while the constraint-based display increases the resilience of the pilot-vehicle system towards unexpected, off-nominal situations. Twelve helicopter pilots with varying flight experience participated in an experiment in the SIMONA Research Simulator at Delft University of Technology. Contrary to expectations, the experiment revealed no significant effects of the displays on any of the dependent measures. However, there was a trend of decreasing pilot workload and increasing situation awareness when employing any of the support displays, compared to the baseline HUD. Pilots preferred the advisory display in nominal and the constraint-based display in off-nominal situations, reproducing similar findings from research in the fixed-wing domain. The relatively short time-frame and monotony of the control-task, an already cue-rich baseline HUD condition, and similarity between the displays possibly prohibited revealing larger differences between conditions. Future research will analyze the obstacle avoidance trajectories of this experiment, possibly revealing changes in control strategy caused by the displays, even when the lumped performance measures are similar. A follow-up experiment will focus on a longer task time-frame, more variable situations, and a truly ecological display to investigate the effect of applying Ecological Interface Design and different automation systems in the helicopter domain.

“…One way of increasing resilience is developing and employing novel automation systems that support the pilot in these safety-critical situations. Head-Up Display (HUD) technology has been applied successfully to improve the UCE-level by supplying the pilot with an additional perspective overlay based on data recorded by on-board sensor suites and/or offline maps [5][6][7]. When developing novel automation systems, there are drawbacks to consider: guidance systems (e.g., maneuver cue-following symbology) applied in addition to existing HUD symbology suffered from sensory overload, as the two-dimensional cues were typically added on top of the augmented outside view [8].…”

Current concepts of obstacle avoidance systems provide maneuvering advice [9], increase the perception of obstacles by magnifying them visually [6,10], or provide combined visual/auditory cues [11]. Maneuver-following cues have been implemented recently in a HUD as a tunnel-in-the-sky or virtual leading aircraft [12].…”

This paper investigates the effect of employing different display design principles for humanmachine interaction in helicopters. Two obstacle avoidance support displays are evaluated during low-altitude, forward flight. A baseline Head-Up Display is complemented either by a conventional advisory display, or a constraint-based display inspired by Ecological Interface Design. The latter design philosophy has only been sparsely applied in the helicopter domain. Twelve helicopter pilots participated in an experiment in a research flight simulator. We found no significant effects of the displays on objective performance measures. However, there was a trend of decreasing pilot workload and increasing situation awareness when employing the support displays, compared to the baseline display. The constraint-based display had the largest positive effect, and increased the resilience of the pilot-vehicle system towards unexpected events,
