Evidence for an Issue 7 pieces of evidence for this issue.

fatigue may be induced (Issue #156) - Automation may induce fatigue, possibly leading to poor pilot performance.

  1.  
  2. Evidence Type: Excerpt from Survey
    Evidence: "The response to item seven [Item seven is a 5 point bi-polar statement: 1="Overall, automation increases pilot fatigue", 3 = neutral, and 5="Overall, automation reduces pilot fatigue", average response = 3.76, rating=percentage of respondents : 1=2%, 2=10%, 3=22%, 4=40%, 5=26%] ... reflects positively on automation, suggesting strongly that automation acts to reduce pilot fatigue."

  12. Evidence Type: Excerpt from Survey
    Evidence: Statement 27: "Overall, automation reduces pilot fatigue." From the histograph of the responses in Phase 1 of the study, 52% of the pilots agreed or strongly agreed with the statement and in Phase 2 of the study, 58% of the pilots agreed or strongly agreed with the statement while only 24% disagreed or strongly disagreed in Phase 1, and 30% disagreed or strongly disagreed in Phase 2. The neutral responses were 24% in Phase 1 and 12% in Phase 2. (page 134)

  14. Evidence Type: Excerpt from Survey
    Evidence: "The subject of fatigue has not been explored in this study, and was seldom mentioned by the crews in interviews, questionnaires, or during the jumbseat observations. Where it was mentioned, most commented favorably on what they perceieved as a reduction in fatigue attributable to automation. See Item No. 27" Statement 27: "Overall, automation reduces pilot fatigue." From the histograph of the responses in Phase 1 of the study, 52% of the pilots agreed or strongly agreed with the statement and in Phase 2 of the study, 58% of the pilots agreed or strongly agreed with the statement while 24% disagreed or strongly disagreed in Phase 1, and 30% disagreed or strongly disagreed in Phase 2. The neutral responses were 24% in Phase 1 and 12% in Phase 2. (page 134-135)
