Sage Journals: Discover world-class research

Abstract

This paper presents the results of an experiment designed to evaluate the effectiveness of a pilot workload assessment technique called POSWAT. The motivation for this research arises from the need to evaluate the workload impact of complex cockpit systems being advanced for improved safety, efficiency and reduced pilot workload. In this study 36 experienced instrument pilots gave workload ratings at periodic intervals while making three LOFT type simulated instrument cross-country flights of varying levels of induced workload in a Frasca 141 simulator. Results indicate that the POSWAT workload evaluation method is highly correlated with induced workload. They are also correlated with some, but not all performance measures. Pilot currency was also reflected in POSWAT ratings.
