A major in unmanned aircraft systems has been available at the University of North Dakota since 2009. Other schools now offering the major include Kansas State University and Embry-Riddle Aeronautical University. The degree includes a combination of science, technology and engineering. "It's not just aerospace engineering; it's not just mechanical engineering. It's electrical engineering, mechatronics, sensor and human factors," said Daryl Davidson of the Auvsi Foundation, part of the Association for Unmanned Vehicle Systems International.
