Single Pilot Operations in Domestic Commercial Aviation

Abstract

OBJECTIVE: To provide an overview of concepts of operation for single pilot operations (SPO) and a synthesis of recently published work evaluating these concepts. BACKGROUND: Advances in technology have made it possible for a commercial aircraft to be flown by a single pilot under normal conditions, and research is being conducted to examine the feasibility of implementing SPO for commercial aviation. METHOD: Context leading up to the consideration of SPO for commercial flight is provided, including the benefits and challenges. Recent studies examining issues relating to automation, operations, and communications in the SPO context are presented. RESULTS: A number of concepts have been proposed and tested for SPO, and no one concept has been shown to be superior. Single pilots were able to successfully resolve off-nominal scenarios with either the ground-support or cockpit-automation tools examined. However, the technologies developed in support of these concepts are in prototype forms and need further development. CONCLUSION: There have been no obvious "show stoppers" for moving toward SPO. However, the current state of research is in its initial stages, and more research is needed to examine other challenges associated with SPO. Moreover, human factors researchers must continue to be involved in the development of the new tools and technologies to support SPO to ensure their effectiveness. APPLICATION: The research issues highlighted in the context of SPO reflect issues that are associated with the process of reducing crew members or providing remote support of operators and, more generally, human interactions with increasingly autonomous systems.
