This volume contains five complete manuscripts and two abstracts presented, and three papers submitted but not presented, at this symposium on aviation psychology. The objective of the symposium was to critically examine the impact of high technology on the role, responsibility, authority, and performance of human operators in modern aircraft and air traffic control systems. Papers are grouped by the following subject area categories: 1) cockpit monitoring concepts; 2) cockpit information systems; 3) pilot judgment; 4) vision and visual perception; 5) crew workload, coordination, and complement; 6) pilot selection; 7) pilot training; and 8) performance assessment.
