Synopsis: "While one of the design goals of automation is to reduce crew workload, little is known about the true relationship between workload and automation. This paper discusses the approaches taken by Airbus Industrie when designing increasing levels of automation into their aircraft. ... The Airbus approach to workload measurement and estimation assumes that the pilot himself can best judge workload by integrating the various workload dimensions into a single scale rating. ... It involves interrogating the pilots for scaled workload assessment ratings throughout the minimum crew certification route-proving flights." The information gathered from the A310 certification was then used to develop the Airbus Workload Model which is "a mathematical model of the rating process. ... Workload measures calculated by the Model were used to demonstrate the workload characteristics of the A320 as partial fulfillment of the requirements for its certification." Data was "collected during the minimum crew certification flights for the A320."
