Helios tapped for Singapore safety case

Consultancy Helios is working on a new major contract with the Civil Aviation Authority of Singapore (CAAS) to deliver a safety case for the launch and operation of its latest ATC system upgrade.

The new system will help CAAS maintain its strategic goal of being a leader in the region. The ATC system upgrade includes 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 are working alongside CAAS colleagues. It is implementing 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, Helios is facilitating workshops and on-site activities, engaging with CAAS ATC operational and technical staff, Thales as main equipment supplier and the regulator to ensure the appropriate interface between operational and technical safety elements.

Focusing particularly on changes to the Human Machine Interface (HMI) and operational environment, the Helios team is working 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 have 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.

Project manager Glen Smith explains: “Whilst interfacing with industry best practice and guidelines is important, it is just as important that the safety assurance methods are relevant to the CAAS operating environment. They must also harmonise with the already established processes and practices within the operational units and company divisions.”
