Autopilot System. However, the user has to keep a check on the course changes as in some cases when the gyro compass wanders its course, the auto-pilot will follow the wandering compass and fail to sound the alarm. As it stood, increased automation hadnt reduced human errors on the whole; it had simply changed their form. The rest exhibited the same behavior that Casner and Schooler had identified in their earlier study: mind-wandering. Researchers refer to this as the automation paradox. As Mark Scerbo, a psychologist and human-factors expert at Virginias Old Dominion University, has explained, The irony behind automation arises from a growing body of research demonstrating that automated systems often increase workload and create unsafe working conditions., The anecdotal and theoretical evidence collected through accident reports, surveys, and studies received empirical backing from a rigorous experiment conducted by Matthew Ebbatson, a young human factors researcher at the University of Cranfield, a top U.K. engineering school. focus or to fall victim to tunnel vision.

This creates intense workload. A 1989 report from NASAs Ames Research Center noted that, as computers had begun to multiply on airplanes during the preceding decade, industry and governmental researchers developed a growing discomfort that the cockpit may be becoming too automated, and that the steady replacement of human functioning by devices could be a mixed blessing. Despite a general enthusiasm for computerized flight, many in the airline industry worried that pilots were becoming over-dependent on automation, that manual flying skills may be deteriorating, and that situational awareness might be suffering., Many studies since then have linked particular accidents or near misses to breakdowns of automated systems or to automation-induced errors on the part of flight crews. Despite the fact that auto-pilot systems varies in model from ship to ship, its working principle and features will be the same. google_ad_width = 336; It is impossible to mention all of its contents at the same instant.
