What is a key feature of urban air mobility vehicles?

Urban air mobility vehicles are designed with vertical takeoff and landing (VTOL) capabilities as a key feature. This design is particularly advantageous for urban environments where space for traditional runways is limited. VTOL allows these vehicles to operate in urban areas by taking off and landing in smaller areas, such as rooftops or designated landing pads. This capability enhances their practicality for short-distance travel within cities, thus complementing existing ground transportation systems and reducing congestion.

The other options present characteristics that do not align with the primary focus of urban air mobility vehicles. For instance, requiring a pilot on board represents traditional aviation standards rather than the innovative changes in urban air mobility, which often explore autonomous operations. Additionally, these vehicles are generally smaller than traditional aircraft to enable efficient operation in crowded urban settings rather than being larger. Finally, urban air mobility vehicles are designed for short, local missions rather than international travel, which involves longer distances and different regulatory requirements.
