Modelling the Influence of Autonomous Systems on Pilot Workload during Helicopter Operations


 This report provides a comparison of modelled pilot workload encountered by a two pilot crew flying a helicopter during a simulated Arctic resupply mission to one that involves a single pilot and an autonomous agent conducting the same mission. The goal was to determine how the pilot tasks and workload changed, and whether the implementation of an autonomous system along with a monitoring pilot would reduce or increase the overall crew workload. This report contains a description of the helicopter mission, a list of assumptions bounding the task analysis, a description of the task analysis, and a comparison of workload at each stage of the mission. Emergency conditions and off-nominal operations were not considered in this analysis. The data revealed that in many cases (e.g. in normal operations with the assumed autonomous capability), despite the addition of new tasks for the aircraft captain, the autonomous system reduced overall crew workload by replacing the flying pilot with an autonomous system.
