Vahana started in early 2016 as one of the first projects at A? the advanced projects outpost of Airbus Group in Silicon Valley. The aircraft we're building doesn't need a runway, is self-piloted, and can automatically detect and avoid obstacles and other aircraft. Designed to carry a single passenger or cargo, Vahana is meant to be the first certified passenger aircraft without a pilot. We'll discuss the key challenges to develop the autonomous systems of a self-piloted air taxi that can be operated in urban environments.
