Corridor Design and Separation Definition in Advanced Air Mobility: Systematic Literature Review
For researchers and practitioners in AAM, this review identifies critical gaps in corridor design and separation standards, but the proposed frameworks are conceptual and not validated.
This paper systematically reviews 62 articles on corridor design and separation standards for Advanced Air Mobility (AAM), finding a lack of integrated approaches and reliance on conventional aviation standards. It proposes unified frameworks and taxonomies to guide future safe and efficient eVTOL operations.
Advanced Air Mobility (AAM) uses electric vertical take-off and landing (eVTOL) vehicles to address urban congestion and emissions. However, corridor design, operation management, and separation standards remain underexamined for safe high-density operations. This paper applies the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to systematically review relevant literature from IEEE Xplore and Web of Science, focusing on publications from 2010 to 2024. A Context, Intervention, Mechanism, and Outcome (CIMO) framework guided the development of research questions. After screening 2,039 journal and conference papers, 62 articles met the inclusion criteria. The findings reveal a lack of integrated corridor design approaches, limited operational strategies, and reliance on standards originally designed for conventional aviation. A unified corridor design and separation definition frameworks and taxonomies are proposed to address these shortcomings, informing future investigations and operational frameworks for safe, efficient eVTOL operation deployment in urban settings.
