  2. Evidence Type: Excerpt from Experiment
    Evidence: "There were slightly more (61 percent) advanced cockpit (EFIS and/or NAV control) than traditional cockpit aircraft in the data set...It was expected that advanced cock-pit aircraft would be more likely to be involved in crossing restriction alti-tude deviations due to the greater complexity in programming descents and descent crossing fixes. While we did see this pattern, the difference in numbers between advanced and tradi-tional cockpit aircraft was not large." (page 13)
    Issue: data entry and programming may be difficult and time consuming (Issue #112) See Issue details
    Strength: +3
    Aircraft: various
    Equipment: FMS & ATC

  4. Evidence Type: Excerpt from Experiment
    Evidence: Cockpit Workload Reporters cited cockpit workload on SIDs and STARS as a factor in 44 percent of reports. The most commonly noted workload issues are shown in Table 2. @I “I tried unseuccessfully to enter the restriction in the FMS. After three attempts, the Captain tried unsuccessfully and tried to explain why it wouldn’t take. Meanwhile, no descent was started.. . We are flying an airplane, not a computer. My focus on the FMS got in the way of doing a very simple descent profile. I will be focusing on flying first, programming second. " (# 259889) (page 14)
    Issue: automation may adversely affect pilot workload (Issue #79) See Issue details
