A systematic literature review of human-centered design approach in single pilot operations

Single Pilot Operations (SPO), as a NextGen concept of operation, can save both crew costs and human resources for airlines, and has attracted the attention of aviation researchers. To explore in advance the problems that the introduction of SPO into the aviation system would bring, the Human-Centered Design (HCD) approach has been widely used in the development of SPO. A systematic review of the progress of HCD approach in SPO research can promote further development of SPO. In this paper, the literature resources of SPO were firstly retrieved from scientific research databases by subject search and were used as the input of scientometric analysis to obtain the highly cited literature, the number of annual publications, and the co-authorship network, which enables readers to understand the research trends and research groups of current SPO. Secondly, the development, application, and research process of the HCD approach were introduced in detail, and the progress of the HCD approach in SPO research was reviewed systematically from three aspects: concept design, function allocation, and system evaluation. Finally, limitations of current SPO research and future research directions for applying the HCD approach to SPO were also discussed.
