Narrative:

An unmanned aircraft was operating in the vicinity of ZZZ under a FAA 333 exemption authority. The aircraft was positioned about 1000 feet north of the runway flying parallel to the runway at 400 feet. At this time; a manned aircraft made a radio call that they were on 'short final for runway ...' no prior radio call was made by the manned aircraft as they approached the area. The first radio call was made while the manned aircraft was approximately one mile from the approach end of runway. The uas operator immediately commanded the aircraft to return to the south of the airfield where the ground control station was located in order to avoid the landing traffic. A radio call was also made by the uas operator identifying the position of the unmanned aircraft but no reply was heard from the manned aircraft. As the manned aircraft crossed the threshold of the runway; the uas was south of the runway by approximately 500 feet and maintaining 400 feet. The manned aircraft did not take any evasive maneuvers to avoid the unmanned aircraft and proceeded to do a touch and go. Several radio calls were made by the uas operator but no replies were heard. While the unmanned aircraft was established in an orbit south of the runway; the manned aircraft made left traffic and climbed above pattern altitude and departed the area to the west. The manned aircraft made a final radio call indicating they had seen the uas but did not acknowledge any radio calls by the uas operator.
