Traffic in Turkish airspace witnessed an overall increase of 10.7% on the previous year, well above the European average. The charts above show the evolution of traffic over the previous years and the breakdown of IFR flights.
Traffic volume is higher in the summer period due to tourism activities, and this is expected increase in the future.
Notwithstanding the great growth in traffic, the ATM system has been able to absorb this increase, and Ankara and Izmir ACCs generated no en-route ATFM delays during 2006. Istanbul ACC did experience some delays in the peak tourist season (July-August 2006) at Istanbul Atatürk Airport, due to the large increase in traffic and because of equipment failure. However these delays were eliminated through common actions agreed between the Istanbul FMP and the CFMU.
It has been noted that the continuous traffic growth has resulted in the reserve capacity being eroded, meaning that the existing system was no longer capable of economic upgrading to satisfy the extra capacity needs. In the light of this, Turkey has accelerated its SMART (Systematic Modernisation of ATM Resources in Turkey) Project to allow an early implementation of an interim upgrade of the ATM systems in the existing ACCs and APPs. The interim upgrade is planned for completion by 2008 and the full implementation of the SMART project (including a Centralised-Turkish ACC in Ankara) will be completed by the end of the summer in 2010.
The airspace structure will be further modified through the implementation of the SMART Project. The new centralised ACC to be built in Ankara will provide control services for all en-route traffic above FL 245. The other ATC units (Istanbul and Izmir) will provide only approach services. The sectorisation of the ATC units has been the subject of the studies carried out by the DHMi and the EUROCONTROL Agency, but it could also be re-arranged during the implementation phase of the SMART Project.
In the meantime, the DHMi has also taken necessary measures to ensure the system has the capacity and redundancy to work in a safe and reliable way up until the operation of the Interim SMART system in 2008.
Turkey has implemented the major route network re-organisation through the new route network package, containing three international and four domestic ATS routes:
- New international ATS routes:
- UP 146 (TRABZON VOR - AGRI VOR - AGINA) between Turkey and Iran (with a new FIR boundary entry/exit point, AGINA),
- UT 30 (AGRI VOR - DASIS) between Turkey and Iran
- G/UG 901 (CARSAMBA VOR - BALUM) between Turkey and the Russian Federation (with a new FIR boundary entry/exit point, BALUM)
- New domestic ATS routes:
- W/UW 711 (TOKAT NDB - ENFOR)
- W/UW 714 (YALOVA VOR - YENİŞEHR VOR - EDASA - AFYON VOR)
- W/UW 715 (BEYKOZ VOR - YENİŞEHR VOR - EDASA - AFYON VOR)
- UT 61 (SINOP VOR - NENDO - BAGLUM VOR)
By means of these new ATS routes and FIR boundary entry/exit points, the ATS route network meets the requirements of international civil aviation and airspace users, as well as the specific national and international needs of the states concerned. Additionally, some TMAs have been re-organised, together with the necessary SIDs/STARs, which ensure the connection with the new ATS route structure.
