Improved decision-support for air traffic management and planning

"Through a series of workshops Agena successfully helped us capture and model our business problem and hence enhance our safety management capabilities. It was always a pleasure to work with the Agena team, and the risk models produced were of high quality and provided excellent added value."

Julia Sonander, Safety & Performance Management, NATS UK


  • Decisions on architectural improvements to the National Air Traffic Control system must be determined on the basis of cost effectiveness and safety
  • Traditional decision-making processes do not provide repeatable, auditable, or quantitative arguments, and rely heavily on the knowledge and experience of key National Air Transport Services (NATS) staff
  • This knowledge and experience may be lost to future assessors when staff move on


  • AgenaRisk was used to model the entire air traffic monitoring (ATM) system and make crucial predictions about collision avoidance
  • Using AgenaRisk, NATS were able to see how the number of "near misses" and the probability of an actual mid-air collision changed when the ATM architecture was modified in different ways


  • AgenaRisk supports faster, more auditable, repeatable and quantified decision-making
  • AgenaRisk enables architectural changes to be assessed on the basis of their quantified impact on safety
  • AgenaRisk captures knowledge for future generations of experts
