Psychol."],"abstract":"<jats:p>We argue that providing cumulative risk as an estimate of the uncertainty in dynamically changing risky environments can help decision-makers meet mission-critical goals. Specifically, we constructed a simplified aviation-like weather decision-making task incorporating Next-Generation Radar (NEXRAD) images of convective weather. NEXRAD radar images provide information about geographically referenced precipitation. NEXRAD radar images are used by both pilots and laypeople to support decision-making about the level of risk posed by future weather-hazard movements. Using NEXRAD, people and professionals have to infer the uncertainty in the meteorological information to understand current hazards and extrapolate future conditions. Recent advancements in meteorology modeling afford the possibility of providing uncertainty information concerning hazardous weather for the current flight. Although there are systematic biases that plague people\u2019s use of uncertainty information, there is evidence that presenting forecast uncertainty can improve weather-related decision-making. The current study augments NEXRAD by providing flight-path risk, referred to as the Risk Situational Awareness Tool (RSAT). RSAT provides the probability that a route will come within 20 NMI radius (FAA recommended safety distance) of hazardous weather within the next 45 min of flight. The study evaluates four NEXRAD displays integrated with RSAT, providing varying levels of support. The \u201cno\u201d support condition has no RSAT (the NEXRAD only condition). The \u201cbaseline\u201d support condition employs an RSAT whose accuracy is consistent with current capability in meteorological modeling. The \u201cmoderate\u201d support condition applies an RSAT whose accuracy is likely at the top of what is achievable in meteorology in the near future. The \u201chigh\u201d support condition provides a level of support that is likely unachievable in an aviation weather decision-making context without considerable technological innovation. The results indicate that the operators relied on the RSAT and improved their performance as a consequence. We discuss the implications of the findings for the safe introduction of probabilistic tools in future general aviation cockpits and other dynamic decision-making contexts. Moreover, we discuss how the results contribute to research in the fields of dynamic risk and uncertainty, risk situation awareness, cumulative risk, and risk communication.<\/jats:p>","DOI":"10.3389\/fpsyg.2020.566780","type":"journal-article","created":{"date-parts":[[2020,12,17]],"date-time":"2020-12-17T16:55:57Z","timestamp":1608224157000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["Effects of Probabilistic Risk Situation Awareness Tool (RSAT) on Aeronautical Weather-Hazard Decision Making"],"prefix":"10.3389","volume":"11","author":[{"given":"Sweta","family":"Parmar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rickey P.","family":"Thomas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2020,12,16]]},"reference":[{"key":"B1","year":"2013","journal-title":"Demonstration Comparing the Effects of Probabilistic and Deterministic Forecast Guidance on Pilot Decision-Making and Performance (Report No. FAA-20130902.1)."},{"key":"B2","year":"2015","journal-title":"ATSC Support To The Weather Technology in the Cockpit Program: Objective One Final Report (DTFAWA-14-C-00043) (Report No. FAA-20150930.1)."},{"key":"B3","doi-asserted-by":"publisher","first-page":"242","DOI":"10.1177\/0018720815610271","article-title":"The effect of incorrect reliability information on expectations, perceptions, and use of automation.","volume":"58","author":"Barg-Walkow","year":"2016","journal-title":"Hum.
