Abstract
Physiological, subjective and mission effectiveness measures were evaluated to test their relative sensitivity and diagnosticity to pilot workload in a part-mission simulation. Two different radar displays were evaluated in an air-to-air simulated scenario using an advanced horizontal situation format display vs the conventional radar display. Data were recorded during the ingress and engagement portions of the mission. The engagement segments were associated with higher subjective workload estimates, smaller cardiac IBIs, fewer eye blinks and shorter duration eye blinks. The new display was associated with shorter duration eye blinks than the current generation display. None of the other measures were associated with statistically significant changes due to display type.
