Limited ranges of all-electric, vertical take-off vehicles, significantly higher transport costs compared to existing, alternative modes of transport, as well as the availability of vertiports with sufficient take-off and landing capacity remain key limiting factors for the market potential of urban air mobility for passengers. Without technological solutions, only a small share of trips can be replaced by urban air mobility, leading to no impact on the existing congestion problem in cities. Therefore, activities should focus more on use cases to improve connectivity of rural areas and the accessibility of airports.
