Aviation Week reports that NASA has moved to a new phase of small UAV “detect-and-avoid testing” in which the agency’s Ikhana UAV will fly within the National Airspace System (NAS) without a chase aircraft following. A two-and-a-half-hour flight on June 12 “validated initial FAA standards for detect-and-avoid (DAA) systems developed by NASA and industry and extensively tested in previous flight campaigns.” The flight marked the completion of the “first phase of NASA’s UAS in the NAS program.” Under the second phase, a DAA sensor “with low cost, size, weight and power” will be developed for small unmanned aircraft “too small to carry” an air-to-air radar developed for the MQ-9/Predator B. The radar will be “installed on NASA’s Sierra-B research unmanned aircraft, a Group 3 UAS with a gross weight of 480 lb. and wingspan of 20 ft., and flown in two further flight test campaigns” as part of phase two.(Image: NASA's Ikhana unmanned aircraft on a Southern California wildfires imaging mission.
