Details

The MAA is investigating and trialling the utility and value of the methodology with a view to:

  • better visually represent pan-duty holder key issues
  • providing earlier or predictive identification of ‘hot spots’ based on barrier/escalation factor hit count; this would in turn better support risk base assurance
  • allocating or associating regulations to specific barriers with the intent of identifying areas requiring regulation development and review
  • developing a common methodology and approach with Civil Aviation Authority and the regulated community
  • maturing MAA understanding of the main air safety issues through small medium enterprises workshops
