Under international treaties, such as the Chicago Convention, the safety regulation of civil aviation is a national responsibility. Every state has complete and exclusive sovereignty over airspace above its territory.
Each state signatory of the Chicago Convention is responsible for ensuring safety and undertakes to keep its own safety regulations, its air navigation equipment and operations compliant with those established by the International Civil Aviation Organisation (ICAO) under the Chicago Convention.
The operation of safety-related air traffic industries within, or on behalf of, States must be on the basis of achieving levels of safety which are both publicly and politically acceptable and this has to be demonstrated to all parties.
In Ireland the responsibility for the safety of Air Navigation Services (ANS) is addressed mainly in terms of two prime safety functions:
The EC Regulation 549 /2004 ‘The Framework Regulation' (Article 4) mandates that each State establish a National Supervisory Authority (NSA) with responsibilities for the supervision of Air Navigation Service Providers (ANSPs). The Safety Regulation Division of the IAA has been nominated as the National Supervisory Authority for Ireland.
It is the policy of the Air Navigation Services Division:
The objective of Safety Regulation in ANS is to improve safety levels by ensuring that the numbers of ANS induced accidents, and of serious or risk-bearing incidents, do not increase and where possible decrease.
Safety regulation is founded on a number of concepts that may be summarised as follows:
Regulation shall be carried out on all safety-related aspects of the systems under the control of the Service Provider. This regulation shall be achieved principally by rulemaking and oversight.
Rulemaking is the process by which safety objectives and requirements are set. It consists of the definition of applicable requirements and associated standards and practices to ensure that both national minimum levels of safety and regulatory provisions that result from international commitments are observed.
Oversight may be defined as the function undertaken by a designated authority to verify that safety regulatory objectives and requirements are effectively met.
The IAA Safety Regulation Division's Air Navigation Services Department is the independent regulatory authority for ANS safety regulation as designated by the Irish Aviation Authority.
Regulatory authority is derived from:
Irish Aviation Authority Act, 1993 and from a number of Statutory Instruments issued under this act including:
Irish Aviation Authority (Air Traffic Services Systems) Order, S.I. No. 855 of 2004
Irish Aviation Authority (Air Traffic Control Standards) Order, S.I. 856 of 2004
Irish Aviation Authority (Eurocontrol Safety Regulatory Requirements) Order, S.I. 387 of 2003
Directions issued by the Chief Executive of the Irish Aviation Authority.
Commission Regulation (EC) No 1315/2007 on safety oversight in air traffic management.
