Rather than using traditional “race track pattern” holding stacks, Point Merge places arriving aircraft onto defined arcs or tracks, every point on which is equidistant from the runway.  From these arcs, the aircraft make one single turn and fly a continuous descent to the runway. Overall track miles flown by the aircraft and inefficient maneuvering at low levels are reduced. 

Point Merge is a component part of the Dublin Terminal Area 2012 Project (TMA 2012), which involves several other measures that work together to enhance the efficiency of the airspace surrounding Dublin airport. Additionally, a new air route for traffic departing from Dublin will help reduce air traffic congestion particularly during the busy morning period. 

The reorganization of Dublin’s air traffic control (ATC) sectors will further enhance ATC efficiency, helping to maintain the IAA’s position as one of the lowest cost providers of Terminal Air Traffic Management services in Europe. 

The TMA 2012 project is the result of over two years’ intensive research and development by a dedicated IAA project team in conjunction with Euro control and supported by our civil and military partners in the UK-Ireland FAB.
