“…Moving-Horizon Versus Moving-Aircraft: Effectiveness of Competing Attitude Indicator Formats on Recoveries From Discrete and Continuous Attitude Changes Maintaining a proper mental representation of an aircraft's position and movement relative to the Earth's surface is of paramount importance for pilots (Previc & Ercoline, 2004). It requests a pilot's constant awareness of the aircraft's position relative to the natural horizon's position.…”

The present research revisits the old issue whether attitude information is best conveyed to pilots in a moving-horizon format or in a moving-aircraft format. Previous research has suggested that the moving-aircraft format might not be beneficial for flight path tracking but recoveries from unusual attitudes, although the result are not fully consistent. A limitation of studies to date is that the recovery task usually did not involve progressive attitude changes of the aircraft but only sudden discrete changes. Compared with a discrete stimulus, the continuous dynamics might increase the perceived time pressure to respond, which in turn can be expected to amplify the error proneness with a less intuitive format. Two experiments were conducted where flight novices and experienced pilots performed tracking and recover tasks with both formats. Recoveries were performed from both, sudden (discrete) and continuously developing attitude changes. Independent of whether novices or pilots were considered, the general superiority of the moving-aircraft format was confirmed. As expected, the benefits of this format became even more evident with progressive attitude changes. No differences were found for tracking. The results add to the evidence favoring the moving-aircraft over the movinghorizon format for both novices and pilots. The moving-aircraft format of the attitude indicator should at least be considered as a standard for new applications, such as ground control stations of unmanned aerial vehicles. Public Significance Statement:The present studies confirm the general superiority of the moving-aircraft over the moving-horizon reference format of attitude indicators in aircraft cockpits. In addition, it shows that this superiority is even more pronounced for pilots and novices when comparing recovering from realistic continuous attitude changes compared with commonly used sudden discrete changes. The results add MOVING-HORIZON VERSUS MOVING-AIRCRAFT 3 new arguments to the case that an adaption of moving-aircraft displays as new standard for aircraft cockpits would be reasonable and should at least be considered for ground control stations of unmanned aerial vehicles.

“…In type I disorientation (unrecognized), there is no conscious perception of spatial disorientation. We refer to this state as "misorientation," because it may appear to subjects that no problem exists, although their actions will lead them in an erroneous direction (Previc and Ercoline 2004). This is a state of misalignment of perceived heading and true heading while maintaining knowledge of spatial relationships between external cues.…”

“…In type II disorientation (recognized), subjects are aware of the disorientation and attempt to correct their actions. We refer to this state as "disorientation," because subjects are aware that their sense of direction is flawed and may compensate using available external cues (Previc and Ercoline 2004). In this state, directional representation is lost, or perhaps even the knowledge of spatial relationships can be lost, unstable, or inaccessible (Dudchenko 2010).…”

“…A third form of disorientation, which we will not discuss in detail, is type III (incapacitating), in which coordination of vestibulo-occular function is disrupted. In humans, this type of disorientation is accompanied by nystagmus and activation of vestibulospinal reflexes, motion sickness, and strong emotional sensations of fear (Previc and Ercoline 2004).…”

Role of the head-direction signal in spatial tasks: when and how does it guide behavior?

Since their discovery, mammalian head-direction (HD) cells have been extensively researched in terms of sensory origins, external cue control, and circuitry. However, the relationship of HD cells to behavior is not yet fully understood. In the current review, we examine the anatomical clues for information flow in the HD circuit and an emerging body of evidence that links neural activity of HD cells and spatial orientation. We hypothesize from results obtained in spatial orientation tasks involving HD cells that when properly aligned with available external cues, the HD signal could be used for guiding rats to a goal location. However, contradictory inputs from separate sensory systems may reduce the influence of the HD signal such that animals are able to switch between this and other systems according to their impact on behavior.
