The task of landing helicopters on ships is cognitively complex and is bounded by several limitations for safe operation. To design technologies to support helicopter pilots in shipboard operations, a better understanding of cognitive processes underlying helicopter piloting in shipboard landing maneuvers is required. Limitations in prior work on ship-based helicopter pilots motivate more studies to better understand how pilots compensate for difficulties associated with ship motion, air turbulence among other factors. We report a preliminary study that used the Applied Cognitive Task Analysis (ACTA) method. We interviewed three participants who have ground-based helicopter piloting experience. The results indicate that ACTA can be used in eliciting knowledge from helicopter pilots. However, we have identified several caveats with the use of the method for this application. The revised method will be used to interview helicopter pilots with shipboard landing experience. Our study has identified a number of cognitive elements in the task which are associated with task management, divided attention, and noticing anomalies.
Rotorcraft pilots face a number of unique challenges in shipboard-landing maneuvers. Even very experienced rotorcraft pilots find such maneuvers to be challenging and delicate, as they require the pilot’s undivided attention. To minimize risk, these maneuvers are conducted within well-defined boundaries associated with weather and visibility. To expand the envelope of safety, technological aids that augment decision-making capabilities and reduce pilot workload are being proposed. Our paper reports a cognitive task analysis, which involved interviews with five rotorcraft pilots experienced in shipboard-landing maneuvers. Our results reveal cognitive elements in which expertise plays a critical role. We have articulated our understanding on why pilots are faced with difficulties during these critical points, which led us toward design recommendations and system requirements for technological aids and their displays. We have also identified a number of system limitations and quantities of interest, which may be useful in safety evaluations.
This paper provides a detailed explanation of the link between NeoCITIES, a crisis management simulation of emergency response teams, and team cognition. Descriptions of the NeoCITIES simulation structure, interface, and modifications are provided, along with its functionality in effectively studying team cognition. The paper focuses on three commonly examined constructs within the team cognition literature, namely, team situation awareness, team mental models, and information sharing.
The purpose of this paper is to introduce a multiagent model for plan synthesis in which the production of a global shared plan is based on a unified framework based on HTN and POP approaches. In order to take into account agents' partial knowledge and heterogeneous skills, we propose to consider the global multi-agent planning process as a POP planning procedure where agents exchange proposals and counter-proposal. Each agent's proposal is produced by a relaxed HTN approach that defines partial plans in accordance with the plan space search planning, i.e., plan steps can contain open goals and threats.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
