Due to the rising concept of advanced air mobility (AAM), electric vertical take-off and landing (eVTOL) aircraft has become the hotspot for academic research and commercial application. This paper provides a comprehensive review of latest researches related to autonomous eVTOL. It examines key technologies involved in autonomous eVTOL, including automated flight control, sensing & perception, safety & reliability, and decision making. It also addresses the technical, regulatory, and societal challenges associated with the wholesale adoption of autonomous eVTOL into AAM. The paper concludes with a discussion of future trends and recommendations, including the importance of integration with air traffic management, urban infrastructure and human–machine interaction. It aims to be a useful resource for those involved in the research, policy, and industry of autonomous eVTOL technology.
