NASA's Detect-and-Avoidance (DAA) system for drones is looking mighty promising. The agency has just finished its latest phase of of test flights using a remote-controlled Ikhana aircraft equipped with DAA sensors over the Mojave desert in California. NASA's Dennis Hines says they still have to fully analyze the data they gathered from the flights -- the third in a series -- but they found that the drone successfully alerted it remote pilots and performed preprogrammed maneuvers when faced with obstacles. Frank Pace, the president of Aircraft Systems for General Atomics Aeronautical Systems said the flight tests' favorable outcome "represents the maturity of [their] detect-and-avoid system."
