While the FAA is moving ahead with plans for UAS/UAV to have regular access to U.S. airspace by 2015, a number of barriers remain. For UAVs to be treated like manned aircraft, their systems likely need to be qualified to the same standards as civil avioncs — this is a challenge, as each UAS has la...
