Drone airpox report involving a Jabiru J430 near Welshpool

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.

Drone airpox report involving an Airbus A319 near London Heathrow Airport

The UK Airprox Board investigated a drone near-miss reported by an Airbus A319 near London Heathrow Airport on 21 May 2016. Separation distance reported as 30 feet.

The A319 pilot reported descending at 4nm to land on RW27L when a drone was sighted in the 11 o’clock position, extremely close to the aircraft and too late to take any evasive action. The drone appeared to be approximately 1 metre in length and green with possible purple markings.

Reported separation: slightly above / 30 ft (10 m) horizontal.

Aircraft: Airbus A319
Operator: British Airways
Registration: G-EUPK
Flight: BA969
Aircraft altitude: 1200 ft
Separation: 30 feet

Boeing 737 involved in drone near miss incident near Leeds/Bradford Airport

The pilot of a Boeing 737 reported a near miss with a drone while on final approach to runway 32 at Leeds/Bradford Airport (LBA), U.K. on July 9, 2015

The aircraft was passing through 1800 feet on the ILS at the time. Both crew saw a black and white, 4-rotor helicopter type drone to the left of them. The drone was seen too late to take avoiding action and passed abeam them. The assessed the risk of collision as ‘Medium’.

Members of the UK Airprox Board (UKAB) agreed that, even had they been operating using first-person view (FPV), the quadcopter operator should neither have allowed the drone to fly above 1000 feet nor operate over a built-up area. Therefore, because the drone was being flown inappropriately, they determined the cause of the Airprox to be that the drone had been flown into conflict with the B737.
For the drone to have been identified specifically as a black and white 4-rotor drone this indicated that it was probably closer than the pilots’ estimate of 300m. As a result, the Board considered that, in this case, it was therefore likely that safety margins had been much reduced below the normal.
