A southwest Ohio airport has received mobile radar equipment to help with research on drones.
The Springfield News-Sun reports the equipment at the Springfield-Beckley Municipal Airport came through state and federal grants.
An official with the Air Force Research Laboratory at Wright-Patterson Air Force Base near Dayton says the equipment will be used to test beyond line of sight operation of the unmanned aircraft.
Currently drones can only be flown in the line of sight of the pilots. Researchers will test flying them farther and using radar and other technology to avoid crashes.
Art Hubbell, director of operations at the Air Force laboratory, says the Federal Aviation Administration requires that the aircraft be able to avoid airborne collisions with other air traffic.
