İstanbul and İzmir ACCs did not generate any en-route ATFM delays during 2005. Ankara ACC did not generate en-route ATFM delays during 2005 apart from during the 21 July - 30 August 2005 period due to high
traffic growth to/from airports located in southern Turkey. This situation has increased the average delay to 0.4 minutes per flight, while the Provisional Council ATM network delay target is 1 minute for en-route ATFM delay per flight. These delays were eliminated through common actions agreed between Ankara ACC and CFMU.
