The concept of electric vertical takeoff and landing (eVTOL) aircraft has captured the imagination of urban planners, entrepreneurs, and futurists alike. These innovative flying vehicles promise to revolutionize urban transportation, offering a solution to congested city streets and long commute times. However, as with any emerging technology that aims to operate in shared airspace, the global adoption of eVTOLs hinges on the development of robust international standards and collaborations.
