29 November 2017

UK Airprox Numbers – non-SUAS 20-year Trend

The UK Airprox Board (UKAB) published their annual report over 2016. UKAB assessed 265 Airprox in 2016, of which 171 were aircraft-to-aircraft encounters and 94 involved drones/small unmanned air systems (SUAS).

The number of aircraft-to-aircraft encounters was similar to 2015 (when 177 incidents were reported) but the number of drone/SUAS encounters more than doubled compared to 2015 (there were 40 drone/SUAS incidents in 2015).

Of the 171 aircraft-to-aircraft incidents, 58 (34%) were assessed as risk-bearing events where safety was not assured (Risk Categories A & B). This represents a decrease compared to 2015 (when there were 177 overall aircraft-to-aircraft notifications with 79 (45%) risk-bearing outcomes).
