Enterprise Network Modernisation Program

Development of Fault Tree Analysis and System Safety Assessments

The Challenge

Thales is part of consortium delivering the design phase for Airservices Australia’s the ENMP Program, a $1B project to upgrade Airservices Australia’s enterprise-wide telecommunications network. The project involves the design of the telecommunications, radio communications, ADS-B surveillance and network services systems. Plan Safe were engaged to ensure that the critical infrastructure is designed safely and is able to support OneSky operations, as well as future enterprise communications services.

What We Did

Plan Safe conducted Safety Assessment using MIL-STD-882E and Eurocontrol e-SAM, including development of detailed Fault Tree Analysis for the Fast Track Program. The Fault Trees were highly complex, often running into hundreds of pages, and required our detailed and deep knowledge of functional safety analysis. We provided two highly experienced safety engineers to aid Thales in ensuring that the system has been designed to meet the rigorous reliability and safety requirements to support Air Traffic systems and data.

The Outcome

The reports and analysis are contributing to the delivery of a network solution that is resilient, reliable, secure and flexible to support the continued delivery of safe and secure air traffic management and aviation firefighting services across Australia.
