Implemented in December 2012, Dublin Point Merge streamlines the way in which aircraft are sequenced to land at Dublin Airport and uses new techniques to assist airlines to fly in Continuous Descent Approaches (CDAs) to the main runway. It has almost eradicated the need to put aircraft into traditional, circular holding patterns at Dublin and greatly reduces aircraft fuel burn and CO2 emissions.

An independent analysis conducted by NATS (UK Air Navigation Service Provider) established that by using Point Merge, airlines landing at Dublin Airport in 2013 saved 127 kg of fuel, worth €93.10 per flight and reduced their fuel requirement by 19.1% per flight. It also found that aircraft reduced the length of the flight by 11.3 miles, a 17% saving. Point Merge also provided savings of 23,500 tons of CO2, representing a 19% reduction.

Point Merge Extension to Runway 10

After the proven success of the introduction of Point Merge on Runway 28, the IAA introduced Point Merge to Runway 10.  The system lists among its benefits reduction in track mileage flown with consequent fuel saving, enhanced use of airborne avionics and continuous descent approaches and associated environmental benefits. The Runway 10 version differs from the Runway 28 system in that features individual sequence legs, positioned on the ideal track to final approach for Runway 10.
