British Airways A319 at London on Sep 30th 2015, near collision with drone
Last Update: February 26, 2016 / 14:13:08 GMT/Zulu time
The UK Airprox Board released their report stating that the drone was not visible on radar, based on the pilot testimony they assessed there was a high risk of collision with the collision being avoided by chance.
The UK Airprox Board wrote (in this analysis writing the drone was 20-30 meters above, while earlier in reporting the crew testimony reporting the drone was 20-30 feet above the aircraft):
In this incident, reported at 500ft, members opined that the drone operator may well have been flying on First Person View (FPV), for which regulation mandates that an additional person must be used as a competent observer who must maintain direct unaided visual contact with the drone in order to monitor its flight path in relation to other aircraft. Irrespective, the drone was within the Heathrow CTR Class D airspace above 400ft and without permission; as a result of his non-compliance with CAA regulations, the Board considered that the drone was flown into conflict with the A319. As is often the case with drone Airprox, the incident did not show on the NATS radars; the A319 pilot estimated that the drone was 20-30m above and within 30yd of the A319, about a wingspan away. Using this estimate as a guide, the Board determined that the risk was Category A, separation had been reduced to the bare minimum and, notwithstanding the fact that the A319 pilot had seen the drone, he had not been able to manoeuvre so chance had played a major part in events.
