Task Prioritization Factors: Two Part-Task Simulator Studies

Abstract

Cockpit task management (CTM) is the initiation, monitoring, prioritization, execution, and termination of multiple, concurrent tasks by flight crews. In this research, we used 2 part-task simulator studies to elicit from pilots the factors actually used in task prioritization. Analysis resulted in the identification of 12 specific factors that the pilots reported as affecting task prioritization. From the results of these and related studies, we developed a hypothetical framework and model of task prioritization in which procedural consistency, importance to flight safety, and the salience of task-related stimuli are the primary factors that affect task prioritization.
