Drone Safety BowTie
UK CAA Drone Safety BowTie

The CAA has recently published their current analysis of the risks posed by small drones to manned aircraft in the UK.

 

At the time of writing there have been seven confirmed cases of direct in flight contact between drones and civil or military manned aircraft worldwide. The number of occasions where pilots have reported suspected drones in proximity to their aircraft in the UK is increasing; there were 59 such occasions between April 2016 and March 2017. So this is certainly a timely piece of work that helps move things forward by providing a well structured and considered approach to drone safety management.

 

The report uses Bowtie analysis methodology to examine the threats that could cause a loss of safe separation, the potential consequences of proximity between a drone and a manned aircraft, and how these threats and consequences are controlled.

"Bowtie models are regularly used by the CAA to provide an effective, visual depiction of risk" 

The full report is available at: http://publicapps.caa.co.uk/docs/33/CAP1627_Jan2018.pdf

and the Bowtie diagram is available at: www.caa.co.uk/CAP1627BT 

 

At Across Safety we're proud to have been supporting the CAA for over 7 years on their Bowtie projects (see Significant Seven), great to see it being used to good effect in this analysis.
