The Irish Aviation Authority (IAA) is the agency within the remit of my Department which is the designated body responsible for overseeing the operating standards of aircraft, including helicopters.
I have been advised by the IAA that all aircraft, including helicopters, operating within the ‘Dublin Control Zone' i.e. Greater Dublin Area, are subject to an air traffic control service provided by Dublin Air Traffic Control (ATC). This airspace is classified and designated as Class C airspace and air traffic control clearances are issued by ATC to all aircraft operating within this airspace — Rules 26 to 29 of S.I. No. 72 Irish Aviation Authority (Rules of the Air) Order, 2004 refers.
Individuals may contact the Authority directly with any concerns regarding safety matters arising from helicopter operations in their areas.
The IAA has informed me that legislation relating to the regulation of helicopters can be viewed on their web site www.iaa.ie.
