The Irish Aviation Authority (IAA) has apologised to customers for the continuing disruption arising from technical difficulties with its radar system at Dublin Airport.
A statement from IAA read: "In the interest of safety, air traffic control at Dublin Airport has restricted its operations. We are confident that we have identified the cause of the problem, the system has been stabilised and is now operating at 70 per cent capacity.
"The system suppliers, Thales ATM, are currently conducting a full testing and analysis process, following which we will move safely towards full operating capacity.
"Regardless of commercial pressures, the safety of aircraft, passengers and crews is of paramount importance to the Irish Aviation Authority. Any increase in capacity will only be made following complete assurance from the IAA's engineers and our equipment supplier Thales that such an increase is safe."
Intending passengers should contact their airline for updated flight information.
