Customer Success Stories

Air Traffic Control Services Limited

Air Traffic Control Services Ltd (ATCSL) is responsible for the safe movement of over of 120,000 aircraft per year and over 6 million passengers at Liverpool, Doncaster, Durham and Carlisle airports . Having recently undergone a phase of expansion ATCSL wanted to update their SMS to incorporate industry best practices in risk analysis and safety management. Also critical was the need to provide consistency across all of their sites. After seeing a presentation by the CAA on BowTie and how that was being used, they contacted Across Safety to explore options.

After identifying the barrier-based risk analysis methodology, BowTie, as an ideal safety management tool, the UK CAA chose Across Safety to support them on a high profile industry initiative known as ‘The Significant Seven’. The project included delivery of 24 BowTie templates, which covered the main safety risks for Commercial Air Transport (CAT) operations in the UK for industry and regulator use. The templates are available on the UK CAA website and are widely used by organisations across the world.

UK Air Accident Investigation Branch (AAIB)

The Air Accidents Investigation Branch (AAIB) investigates civil aircraft accidents and serious incidents within the UK, its overseas territories and crown dependencies. Its purpose is to enhance aviation safety by determining the circumstances and causes of air accidents and serious incidents, and promoting action to prevent recurrence. It is not to apportion blame or liability. 

In 2016, they chose Across Safety to help them assess the barrier based investigation tool IncidentXP and subsequently apply it to their investigation process.
