The research on task unit workload of civil aircraft flight operation

Abstract

The paper aimed at studying the unit workload of civil aircraft flight operation task, and studying and analyzing the influence of the flight experience and flight stage on the single-task workload. Firstly, the less experienced and experienced pilots were chosen as the assessment objects to get the single-task workload so as to analyze the influence of the flight experience on the task workload. Then, the pilots were used as the assessment objects, and the objective assessment method was used for assessing the operation single-task workloads under different flight phases so as to analyze the influence of the flight phase on the operation single task. The results indicated the flight experience didn’t influence the task workload, and the task workload values under different flight phases were greatly differed, and the workload values were ranked from high to low as follows: approach stage, takeoff stage, climb stage and cruise stage. The analysis results of the influences of the operation task unit workload, flight experience and flight stage on the task unit load value could provide basis for studying the pilot’s workload.
