Abstract. The purpose of this study was to examine how pilots respond to conflicting information on the flight deck. In this study, 108 airline, corporate, and general aviation pilots completed an online questionnaire reporting weather, traffic, and navigation information conflicts experienced on the flight deck, including which information sources they trusted and acted on. Results indicated that weather information conflicts are most commonly experienced, and typically between a certified source in the panel and an uncertified electronic flight bag application. Most participants (a) trusted certified systems due to their accuracy, reliability, recency, and knowledge about the source, and (2) acted on the certified system due to trust, being trained and required to use it, and its indicating a more hazardous situation.

Before embarking on a flight, pilots need to acquire information about the actual and forecast weather conditions. Concerns have been raised about the traditional coded format used to provide this information. Software developers have recently provided tools for generating both plain-English and graphical versions of these coded weather observations. We show how we successfully applied a number of ergonomic display principles to improve the graphic display of weather information for general aviation pilots.

Interruption Management

Despite the increasing availability of technologies that provide access to aviation weather information in the cockpit, weather remains a prominent contributor to general aviation (GA) accidents. Pilots fail to detect the presence of new weather information, misinterpret it, or otherwise fail to act appropriately on it. When cognitive demands imposed by concurrent flight tasks are high, the risks increase for each of these failure modes. Previous research shows how introducing vibrotactile cues can help ease or redistribute some of these demands, but there is untapped potential in exploring how vibratory cues can facilitate “interruption management”, i.e., fitting the processing of available weather information into flight task workflow. In the current study, GA pilots flew a mountainous terrain scenario in a flight training device while receiving, processing, and acting on various weather information messages that were displayed visually, in graphical and text formats, on an experimental weather display. Half of the participants additionally received vibrotactile cues via a connected smartwatch with patterns that conveyed the “severity” of the message, allowing pilots to make informed decisions about when to fully attend to and process the message. Results indicate that weather messages were acknowledged more often and faster when accompanied by the vibrotactile cues, but the time after acknowledgment to fully process the messages was not significantly affected by vibrotactile cuing, nor was overall situation awareness. These findings illustrate that severity-encoded vibrotactile cues can support pilot awareness of updated weather as well as task management in processing weather messages while managing concurrent flight demands.

Introduction. An essential feature of the professional activity of pilots of civil aviation aircraft is the high intensity of work due to pronounced emotional, intellectual, and sensory loads, unique work modes. The study aims to assess the intensity of work and the prevalence of factors affecting fatigue among civil aviation pilots according to an anonymous online questionnaire. Materials and methods. Experts surveyed 667 members of the flight crews in remote anonymous online questioning. We developed the questionnaires under the criteria for assessing the intensity of work, assessing the risk factors for fatigue development according to the ICAO recommendations, and analyzing the pilot's activity algorithm. The researchers used descriptive statistical methods to analyze the survey data. Results. The working conditions of pilots according to 7 indicators of tension correspond to class 3.2: a high level of intellectual loads (72-100% of pilots), a large number of overlapping time zones (18%), the maximum duration of concentrated observation (70.7%), a high density of signals and messages (29.9%), a significant number of objects of simultaneous observation (18.9%), a high degree of risk to one's own life and responsibility for the safety of others (98%), as well as a rough working day (79%). According to the totality of indicators, the general class of labor intensity corresponds to the highest degree (class 3.3). The factors affecting the fatigue of pilots include rare rest between flights (44.6% of respondents), intermittent sleep (59.9%), not always a full sleep before the night flight shift (85.9%). According to the survey results, the share of pilots who have spontaneous sleep during the flight is 74.3%, and frequently delayed reaction to usual, non - standard, or extreme stimuli and signals is 12.3%. Conclusions. The obtained data of the questionnaire survey confirm the results of psychophysiological studies that have shown that the level of the labor intensity of pilots is "super-intense or extreme." Therefore, considering the prevalence of factors affecting fatigue among the crew members, and based on the understanding of the fundamental problems noted by the pilots, it is necessary to develop measures and management solutions to minimize the risk factors for fatigue development.

Cockpit Displays

In any Free Flight system, pilots must have displays which effectively depict traffic and weather information as more and more responsibility for separation from such hazards transfers from air traffic controllers to pilots. This research effort seeks to address the issues of dimensionality (3D versus 2D coplanar displays) and data base integration (separation or integration of traffic and weather information within displays). Seventeen general aviation flight instructors flew a series of en route trials with four display types in which dimensionality, data base integration, and hazard geometries were manipulated. Analysis of the data revealed that the 2D displays resulted in a smaller percentage of conflicts with traffic and weather hazards. The results also suggested that displays in which traffic and weather were integrated resulted in fewer hazard conflicts for trials in which both hazard types were critical to maneuver selection. Maneuver strategy was also found to vary by scenario geometry.

The objective of this article is to investigate the problems related to the extensional integration of information sources. In particular, we propose an approach for managing inconsistent databases, that is, databases violating integrity constraints. The problem of dealing with inconsistent information has recently assumed additional relevance as it plays a key role in all the areas in which duplicate information or conflicting information is likely to occur (Agarwal et al., 1995; Arenas, Bertossi & Chomicki, 1999; Bry, 1997; Dung, 1996; Lin & Mendelzon, 1999; Subrahmanian, 1994).
