Welcome to the Across Safety February 2018 Newsletter

Hello and welcome, we've got lots interesting articles and news to share with you in this edition.


We start with the article 'Barriers: How many do you really have?' which explores the different ways barriers function (sometimes in sequence, sometimes in parallel) and the implications this may have on how you interpret a risk assessment. We'll then have a look at how an air traffic control provider has made improvements to their safety management program in this edition's success story featuring Air Traffic Control Services Limited.


By the way, If you’ve not come across Bowtie before you can find out more about how it is used in the aviation industry either on our website or on the UK CAA website.


News-wise, we have:

- the results of the 2017 Across Safety Survey,

- an update on the finalised agenda for the BowTie User Group (or BUG) meeting to be hosted by the UK CAA in March, and

- details of our upcoming Bowtie training courses.


I hope that you find the newsletter informative and useful and I welcome any feedback. You can reach me directly via email at: avenetz@acrosssafety.com

Barriers: how many do you really have?

When looking at barriers in a Bowtie they appear to be sequential, i.e. if one barrier fails then the next one should come into play, but is this always the case? Are barriers sometimes ‘parallel’ rather than ‘sequential’? If so, what does this mean for how you interpret the information in the BowTie and how you rate barrier effectiveness? This article provides food for thought regarding such issues.

Success Stories

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. This article provides an overview of their journey to implement Bowtie to achieve those goals.
