ABSTRACT
This chapter focuses on some of the potential problems that can occur with automated glass cockpits, especially as these problems relate to pilot workload. Pilot workload is measured by evaluating subjective ratings, objective performance on both primary and secondary tasks, and physiological indices. Human factors research has demonstrated that many of the errors and accidents that occur during complex task performance are associated with levels and types of operator workload. The decision to automate flightdeck functions will have, a priori, neither a negative nor a positive effect on pilot workload. The effects of automation on pilot workload will vary as a function of the manner in which key human factors issues are addressed during the design of the automated system. Training requirements are increased by automation, with the potential for commensurate changes in pilot workload. Automation introduces unique training requirements, because pilots must become proficient in both manual and automatic flight modes.
