The Arlington Police Department is in the first part of its experiment in using unmanned aircraft to assist in law enforcement.
The department has been testing and evaluating two battery-operated, remote-controlled aircraft over a small, restricted airspace near Lake Arlington Dam, away from populated areas.
The aircraft are flown only for daylight operations and within a small, restricted airspace. The aircraft have to remain within the pilot's line of sight and fly 400 feet above the ground level.
Pilots obtain the same license as a commercial aircraft pilot.
Arlington hopes to demonstrate the aircraft's potential law enforcement uses. All flight data is recorded and sent to the Federal Aviation Administration for evaluation.
