MRO for VTOLS in a functional sequences solution space

A crucial aspect of emission reduction in urban environments is the development of electrically (or hydrogen) powered vertical take-off and landing vehicles (eVTOLs) and the corresponding infrastructure planning. To ensure the continuous use of these vehicles for urban passenger transport, proactive maintenance methods, plans, and intervals must be established for so-called Vertistops, Ports, and Hubs. In addition to the maintenance schedule, safety restrictions, risk levels, failure modes, and failure hazard analyses must be conducted for taxiing, the maintenance process, and energy management to assess potential safety risks and ensure accident-free operation. This paper provides a literary overview of the current research on maintenance mea-sures and methods. It addresses the maintenance schedule via checklists and presents a revised functional overview for maintaining eVTOLs. Our approach transfers the conventional maintenance planning of airplanes and helicopters using checklists into Business Process Model and Notation (BPMN) diagrams, extended with attributes for the temporal and spatial design of Vertiports. The expansion of the solution space also includes the classification and generation of synthetic damage data for eVTOLs, which is intended to serve as a suggestion for further work in this area. Finally, we conducted a comprehensive safety analysis for the scenario of pre-flight maintenance using an inspection drone, which, in addition to purely visual inspection (e.g., through Smart-Hangar approaches), constitutes part of our solution space."
