AAIB investigation to Parrot Anafi USA, (UAS registration n/a) 030421
Loss of control and flyaway, Quarry Span Hill, Henley on Thames, Oxfordshire, 3 April 2021.
Summary:
While conducting a flight in support of police search operations, the pilot became concerned about losing visual line of sight with the unmanned aircraft (UA) and attempted to activate the return-to-home (RTH) function. The UA had not acquired a GPS signal prior to the flight and therefore did not record its takeoff point, rendering the RTH function ineffective. The UA lost connection with the controller and drifted in the wind. It was located undamaged the next day approximately 5 km away, having performed an automatic landing.
