    [1] Latitude and Longitude are usually only estimates that are based on the reported time of occurrence mapped against any available radar data for the aircraft’s position at that time. Because such reported times may be inaccurate, the associated latitudes and longitudes should therefore not be relied upon as precise locations of the event.

    The A320 pilot reports they were established on the Heathrow ILS RW27R at 8.6nm when the First Officer stated that he could see an object to the right of the aircraft.  The Captain looked and saw what could have been a drone at about the same level, approximately 300m away. It looked more like a drone than a balloon.  It was reported to ATC and the police.

     

    Reported Separation: 0ft V/ 300m H

    Reported Risk of Collision: Not reported.

    The Board were unable to determine the nature of the unknown object.

    The B747 pilot reports on departure from London Heathrow when the crew saw a silver / white drone which passed directly beneath the nose within a few seconds. It was difficult to assess how close the drone was as they did not know its size. They immediately advised London Air Traffic Control of the Airprox. The pilots discussed the object and were both certain that it was not a balloon.

     

    Reported Separation: 300ft V/0m H

    Reported Risk of Collision: Not reported.

    The reported drone was being flown above the maximum permitted height of 400ft and within controlled airspace such that it was endangering other aircraft at that location.

    Gatwick CTR

    (D)

    The A320 pilot reports in the late stages of a manual ILS approach into Gatwick. They had taken on extra fuel due to reports of drone activity in the London TMA and had also been warned on ATIS and by the controller. There had been no reports of sightings recently. Passing about 350ft, slightly right of the centreline, the Captain exclaimed "drone". The F/O looked out and also saw a drone, directly in front of the aircraft, slightly to the left at a range of about 100m. Visual contact was maintained with the drone as it passed down the left side of the aircraft at the same level. The F/O is a drone enthusiast and identified the drone as a DJI Inspire. The crew were unable to perform an evasive manoeuvre due to the speed of the event. The F/O reported the drone sighting to ATC and the crew made a statement to the police after landing. The crew believed that if the autopilot had still been engaged, and they were on the centreline, there was a very high probability that they would have struck the drone.

     

    Reported Separation: 0ft V/ 20m H

    Reported Risk of Collision: High

    The reported drone was being flown within the Gatwick CTR and FRZ and without clearance such that it was endangering other aircraft at that location.

     

    Applicable Contributory Factors: 1, 2, 3, 4, 6

     

    Risk: The Board considered that the pilot’s overall account of the incident portrayed a situation where providence had played a major part in the incident and/or a definite risk of collision had existed.

    The A321 pilot reports he was passing 3420ft turning onto finals for Manchester RW23R when he saw a large black ‘hockey puck’ shaped drone fly over the top of the aircraft. It passed overhead the aircraft by about 50ft, heading south. They were surprised to see a drone so high when on finals and did not have time to take any action.  ATC and the police were informed.

     

    Reported Separation: 50ft V/ 100m H

    London FIR

    (G)

    The EV97 pilot reports that he was on a local sortie when he sighted traffic in the 11 O’clock position which he initially believed to be a helicopter. His attention was drawn to the traffic as it appeared to be glinting in the sun. He commenced a slight right turn to increase separation and to allow the traffic to pass down the left side. As the traffic passed he realised it was actually a red quadcopter drone. The quadcopter then appeared to descend rapidly and he lost visual contact with it. After the traffic had passed he reported the event to Barton Information and continued his planned flight. The pilot noted that  because he had initially believed the traffic was a helicopter, he had perceived it to be further away than was the case due to its small size. Had he realised sooner that the object was a drone he would have carried out a more rapid turn to avoid.

     

    Reported Separation: 0ft V/30m H

    Reported Risk of Collision: Medium

    The reported drone was being flown above the maximum permitted height of 400ft such that it was endangering other aircraft at that location.

     

    Applicable Contributory Factors: 1, 2, 4, 6

    The PA28 pilot reports she was on a nav-ex at 2800ft, she looked to the rear quarter for FREDAL checks and saw a white drone with 4 props 200ft below.

     

    Reported Separation: 200ft V/ 0m H

    Reported Risk of Collision: Medium

     

    The Brize App controller reports that the PA28 pilot was receiving a Basic Service.  At 1658Z the pilot (indicating FL032 on Mode C at the time) reported a drone 200ft beneath them.  Although there was a faint primary track in the area, it looked like radar clutter so no Traffic Information had been given.

    The reported drone was being flown above the maximum permitted height of 400ft such that it was endangering other aircraft at that location.

     

    Applicable Contributory Factors: 1, 2, 4, 6

    (G)

    The R44 pilot reports that while conducting a pleasure flying event on National Trust property in Downhill, Northern Ireland a small drone passed overhead by about 40/50ft while in the last 100ft of his descent to land. He continued with the approach as the drone had gone directly overhead the helicopter. During shut down he saw it fly back overhead.

     

    Reported Separation: 45ft V/0m H

    Reported Risk of Collision: Not reported.

    The reported drone appeared to be being operated within 50m of the helicopter, in contravention of ANO 2016 Article 95(2)(c).

     

    Applicable Contributory Factors: 4, 6

     

    Risk: The Board considered that the pilot’s overall account of the incident portrayed a situation where providence had played a major part in the incident and/or a definite risk of collision had existed.

    Coningsby ATZ

    (G)

    The Typhoon pilot reports overshooting from a low approach when a white and blue quadcopter drone was seen. The drone did not appear to have crossed the boundary fence of the airfield and was not on the RWY centreline. The drone sighting was immediately reported to ATC and the pilot extended upwind for a few seconds to ensure height and lateral deconfliction prior to turning on to an easterly heading; visual contact was lost in the turn after safe separation had been achieved and no risk of collision existed.

     

    Reported Separation: ‘900ft’

    Reported Risk of Collision: Medium

    The reported drone was being flown above the maximum permitted height of 400ft, within the Coningsby ATZ and FRZ and without clearance such that it was endangering other aircraft at that location.

     

    Applicable Contributory Factors: 1, 2, 3, 4, 6

    The A319 pilot reports he was above the cloud in VMC conditions at FL110 near reporting point BRASO.  The FO spotted the drone first and alerted the Captain, it was easy enough to see due to its relative motion ahead of the aircraft, it seemed to be crossing right to left (relative to the aircraft). It was clearly identifiable as a drone, was dark blue in colour with a gloss finish and some black trim.  It appeared to have a dome shape and was thought to be a quadcopter with props close to the body.  There was no opportunity to take any avoiding action, and the crew were a little shaken after the event.

     

    Reported Separation: 0ft V/25m H

    Reported Risk of Collision: High

    The reported drone was being flown above the maximum permitted height of 400ft and within controlled airspace such that it was endangering other aircraft at that location.
