The UK Airprox Board investigated a drone near-miss reported by a Jabiru J430 near Welshpool on 23 June 2016. Separation distance reported as less than 150 m.
The J430 pilot reported downwind in the visual circuit for Runway 22 at Welshpool Airport (EGCW), about 1nm east abeam ‘the 22 numbers’. He saw a white drone in the left 11 o’clock position, about 50m below him, which moved quickly in front of his aircraft and climbed to the 2 o’clock position, about 100ft above, at which point he lost sight of it against the white cloud and behind his wing. He commented that he was well inside the Welshpool ATZ and that the presence of the drone was a needless distraction. He noted that he was surprised at the speed at which the drone moved and the difficulty in judging distance with a small fast-moving object.
Reported separation: 0 ft (0 m) vertical / 490 ft (150 m) horizontal.
Aircraft: Jabiru J430
Aircraft altitude: 1500 ft
Separation: 490 feet
Please note that separation distances are solely based on pilot’s judgements and not necessarily accurate since horizontal and vertical separation distances can be hard to judge.
