The IAA operates some of the most technologically advanced systems in providing its air traffic management services, which are categorised into four domains:
- Communications
- Navigation
- Surveillance
- Flight Data Processing Systems (FDPS)
IAA engineers ensure that this complex network of systems is maintained and certified to the highest international standards. Engineers are based at all of the IAA’s operational facilities providing a 24 hour restoration service, 365 days a year.
Systems maintained include:
- Surface Movements Radar (SMR)
- Search Radar Equipment (SRE)
- Monopulse Secondary Surveillance Radar (MSSR)
- Instrument Landing Systems (ILS) comprising GlideSlope, Localiser, IRVR, DVOR, DME, NDB, and Marker Beacons.
Engineers are based at all airport sites and at the IAA's North Atlantic Communications facility and provide a 24 hour restoration service, 365 days a year.
Engineers also maintain the Air Ground Communications (both VHF and HF) and the COOPANS Air Traffic Management (ATM) system.
Engineers liaise with national providers of met data and telecom infrastructures and also with neighbouring civil aviation authorities with regard to existing technological interfaces.
