Therefore, techniques were analyzed and evolved to ensure airworthiness, operation management, and robust modeling. Hence, we can derive MRO capacities. Therefore, we model the MRO aspects in the RCE tool MROPort. This tool depicts maintenance schedules, downtimes, and intervals. The downtimes are deciding to manage the whole operating system in the holistic system of the AAM. More holistic systems for the MRO will be created with the found boundary conditions of VTOLs and GBI. Furthermore, the space needed for the MROPort will be calculated. With urban management analysis, MROPort placement strategies and MRO downtimes result.enMROVertiportUAMVTOLAirworthinessEngineeringConference Paper10.2514/6.2023-3576Conference Paper
