Cover Story: The extension of the current urban transportation system utilizing the third dimension by air taxis represents a potential solution for the congestion of metropolitan areas. A major asset for AT operations is the connection to existing airports enabling access to multiple transportation systems. This paper develops an analytical model for AT operations and their capacity impact on airports, exemplary for Hamburg airport. The model is developed based on the results of a fast time simulation considering multiple aspects, such as vehicle configuration and touchdown and lift-off areas. Collectively, three integration methods are analyzed, each of them impacting the conventional air traffic differently. Additionally, an energy consumption analysis of the ATs is conducted.
