| 摘要： | The purpose of this study was to examine how change detection affects a pilots enroute flight planning task ability. Pilots were asked to choose between two flight paths that traversed through hazardous airspace. After the flight path choice was made, pilots then monitored this airspace for the purpose of seeking cues and detecting changes, and then, if necessary, revising the initial flight plan choice at two points along the flight path. Automated aids, consisting of highlighted hazards and recommended path choices were provided for the pilots. Results indicate that change detection is affected by both data-driven and contextually-driven factors, but more so by the latter. Findings provide little indication of the existence of the confirmation bias that may have led some pilots to continue traveling on a flight path that had become unsafe. Path choice performance was more accurate, and confidence ratings were higher, for simple than for difficult path choices, and no benefit for automation was found. / NOTE: Technical rept. / Supplementary Notes: Sponsored by National Aeronautics and Space Administration, Moffett Field, CA.
