Civil Aviation Authority of Singapore (CAAS)
Air traffic continues to grow in Singapore and the Asia Pacific region. This places increased emphasis on ATM technologies and solutions to deliver the capacity and continued high safety and service standards needed.
Role of Helios
Helios was contracted to deliver a safety case for the launch and operation of CAAS' latest ATC system upgrade. The new system will help CAAS achieve its strategic goal of being a leader in the region. The ATC system upgrade included new consoles and processing equipment, long-range Primary and Secondary Radars and new ground network infrastructure at the Singapore Air Traffic Control Centre, Singapore Changi Airport and Singapore Aviation Academy.
Operational and technical safety experts from Helios's risk-based safety practice worked alongside CAAS colleagues. We implemented a top-down operational risk solution using a total system approach that covers human, procedures and equipment aspects. Working to a challenging timescale for transition into operations, we facilitated workshops and on-site activities, engaging with CAAS ATC operational and technical staff, the main equipment supplier (Thales) and the regulator to ensure the appropriate interface between operational and technical safety elements, all within around six months.
Focusing particularly on changes to the Human Machine Interface (HMI) and operational environment, the Helios team worked with CAAS controllers, engineers and the ANS Safety Office to identify potential safety risk and establish associated cost-effective mitigation through the setting of safety requirements. As part of this project we applied elements of the ICAO Safety Management Manual (Doc 9859), the latest safety barrier model theory, as well as standardised Safety Assessment Methodologies (from EUROCONTROL).
Whilst aligning with industry best practice and guidelines was important, it was just as important that the safety assurance methods were relevant to the CAAS operating environment and the already established processes and practices within the operational units and company divisions.
