The Operational Requirements Domain is responsible for planning and developing integrated operational requirements for the provision of Air Navigation Services. The Domain consults with all the relevant stakeholders involved in defining the necessary requirements for the procurement of new Air Traffic Management (ATM) systems and sub-systems. Specialised requirements like Human Machine Interfaces (HMI) for use by Air Traffic Controllers (ATCOs) in the day to day Air Traffic Control (ATC) operation, Communication interfaces, ATCO consoles and backup systems require research and analysis before finalisation of requirements. Operational testing and evaluation of new and changed systems is undertaken by Specialists to ensure conformance with requirements before operational commissioning. System lifetime cycle is supported.
The Harmonisation of ATM systems and operational methods with other ANSP partners is a major goal of the Authority to help in improving safety, reducing costs and enhancing capacity in the provision of Air Navigation Service in line with European Union Single Sky requirements. Experts work together with ANSP partners particularly Austria, Denmark and Sweden to harmonise ATM systems. The first harmonised system was commissioned in Ireland (Shannon/Cork and Dublin ATC Centres) in 2011.
