Analysis of pilot assessment of workload.

Abstract : In a previous study on the activity of the nervous system during the let-down, approach and landing of a transport aircraft the workload was assessed by the pilot. Correlations were established between overall workload of the let-down and individual factors which influence the workload pattern and between the subjective assessments of workload and physiological change in the pilot. In the present paper assessments of workload over a four-year period have been examined to determine the technique used by the pilot to evaluate workload from the various factors of the let-down and to assess the consistency of his technique.
