  2. Evidence Type: Excerpt from Survey
    Evidence: "Each of the six individual items that made up the composite score of the self-assessment form was also subjected to ANOVAs of the same design (type-by-seat). Of the six, two resulted in significant results in the contrast of the aircraft type: Physical Demand (Item No. 3) and Frustration Level (Item No. 7). In both cases, the means were higher for MD-88 crews than for DC-9 crews, meaning that MD-88 pilots perceived their jobs as being more physically demanding, and more frustrating. ... for the first officers, Physical Demand was viewed as significantly higher for MD-88 crews compared to DC-9 crews, but for captains there was no significant difference. The Frustration Level rating were significantly higher for both crew members in the MD-88 compared to the DC-9" (page 37)

  4. Evidence Type: Excerpt from Survey
    Evidence: "Results ... The total composite score, a global measure of workload described in the previous section, the contrast between the two aircraft was significant at the 0.051 level (F(1,20) = 4.30). ... The results for the captains were non-significant, however for the first officers the difference between the mean composite workload ratings for the two aircraft were statistically significant, indicating that the MD-88 first officer attributed a higher workload to their cockpit duties than those assigned to the DC-9s. ... The mean workload score for MD-88 F/Os was 30.50, for DC-9 F/Os was 26.67." (page 36)
