As air taxi developers across the globe continue to make advancements in the future of urban mobility, one organization is looking for ways to make sure the aircraft of the future are accessible for all.

The Vertical Flight Society—formerly the American Helicopter Society and the world’s largest nonprofit technical society focused on vertical flight—has announced plans for its 39th annual Student Design Competition. This year’s competitors will be tasked with creating an electric vertical takeoff and landing (eVTOL) aircraft that accommodates passengers with a broad spectrum of mobility difficulties, or other disabilities, for urban air mobility (UAM) missions.

“Some $10 billion has been invested in eVTOL developments over the past six years, with nearly half of that coming just this year,” said Mike Hirschberg, VFS executive director, in a press release. “EVTOL air taxis can provide safe, quiet, affordable, clean solutions for metropolitan transportation needs, so they must be usable by the widest possible segment of the population.”
