Summary

This paper reports on a three-year field study examining the human factors associated with advanced technology ("glass cockpit") transport aircraft, specifically the Boeing 757. The research was motivated by growing industry concerns regarding the increasing sophistication of cockpit automation. While pilots generally welcomed individual automated devices, there was a prevailing fear that the cumulative integration of these systems could lead to "complacency," "automation atrophy," and a loss of situational awareness, effectively causing crews to fall "out of the loop." Additionally, the transition to two-pilot crews, replacing the traditional flight engineer, raised questions about workload management and the ability to maintain extra-cockpit scan in crowded terminal areas. The study aimed to extend previous research by capturing the full range of pilot experiences, focusing on training, error reduction, workload management, and general attitudes toward automation. The methodology involved a comprehensive data collection effort at two major U.S. airlines, referred to as Airline-1 and Airline-2. The study utilized a volunteer panel of line pilots with varying levels of Boeing 757 experience, ranging from those completing initial operating experience to those with over 3,000 hours. Data were gathered through multiple channels: interviews with management pilots, check airmen, and instructors; attendance at ground schools; jumpseat observations during simulator sessions and line operations; and two sets of questionnaires mailed to pilots one year apart (1986 and 1987). The questionnaires included a 36-item Likert scale assessing attitudes toward automation, open-ended questions on specific operational topics, and biographical data. The research design prioritized line pilot opinion as a vast, underutilized database of operational experience, contrasting it with error-focused data from the Aviation Safety Reporting System. The findings indicate that while pilots were generally enthusiastic about flying the advanced technology aircraft, they expressed mixed feelings regarding the impact of automation on workload, crew errors, and flight management. The study highlighted that the limitations of the air traffic control (ATC) system often hindered the full utilization of the aircraft’s advanced features. Pilots reported specific challenges related to training for advanced automation, the management of cockpit workload, and the occurrence of cockpit errors, including altitude deviations. The data revealed that while the "quiet, dark cockpit" design philosophy aimed to simplify systems and reduce routine monitoring duties, it introduced new complexities in crew coordination and resource management. The study also examined the transition training required for moving to and from the Boeing 757, noting concerns about skill retention and the difficulties of transitioning back to less sophisticated aircraft. The significance of this research lies in its detailed documentation of the human-device interface in highly automated environments. By focusing on generic automation issues rather than specific design reviews, the findings provide insights applicable to all advanced technology aircraft. The study underscores the need for improved training programs that address the unique challenges of automated flight, such as maintaining manual flying skills and situational awareness. Furthermore, it highlights the importance of considering the broader operational context, including ATC limitations, when evaluating the effectiveness of cockpit automation. The report concludes with recommendations for expanding automation guidelines to better support designers, operators, and training departments in managing the human factors of advanced technology transport aircraft.
