The assessment of crew workload is normally used as an important parameter to evaluate the overall human-machine efficiency design level of the cockpit. For mature aircraft manufacturers, it is common to use a comparative approach to verify that the crew workload of new aircraft models is acceptable. However, for new aircraft manufacturers, the comparative method is less practical. This study proposes a method based on an independent evaluation strategy, which is being used in the development of the aircraft model, offering a brand-new perspective and approach for the workload validation of new aircraft types.
