B737 (CAT) |
Unk Obj |
5050N 00029E Bexhill-On-Sea FL130 |
London TMA (A) |
The B737 pilot reports passing over the south coast, descending into LGW, when the Captain saw a black object (believed to be a drone) in front of the aircraft. There was no time to take avoiding action and the object passed 10-20m on the right-hand side of the aircraft, approximately 10ft above. The object was reported to ATC and details passed.
Reported Separation: 10ft V/10-20m H Reported Risk of Collision: High
NATS Safety Investigation The B737 pilot submitted an Airprox report in response to the sighting of a drone approximately 10.7NM southeast of TIMBA whilst descending through FL130. It has been estimated that the [reported] UAS was at FL130. Safety Investigations reviewed the radar at the time the B737 pilot reported the sighting, however, no radar contacts associated with the drone were visible. |
In the Board’s opinion the reported altitude and/or description of the object were such that they were unable definitively to determine the nature of the unknown object.
Applicable Contributory Factors: 4, 6
Risk: The Board considered that providence had played a major part in the incident and/or a definite risk of collision had existed. |

[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.
