Turkey established a regional cooperation with its neighbouring states concerning airspace structure, ATS route planning, coordination
methods and ATM procedures.
In the Black Sea region, a Memorandum of Understanding for the Establishment of Air Traffic Management Cooperation in South-Eastern Europe (ACE) was signed on 8 July 2003 by the Director Generals of Civil Aviation of Bulgaria, Moldova, Romania and Turkey. The main objective of this MoU was to optimise regional capacity under the European concepts and frames in order to increase the safety and cost efficiency of air navigation services in the area.
Turkey is increasing its cooperation with its neighbours in the ATM communications field. Within this context, Turkey has carried out a
number of Ground-Ground and Air-Ground Communication Workshops that neighbouring states have attended. Implementation of OLDI links, AFTN, VSAT, etc. with Greece, Bulgaria, Iran and Ukraine are a part of near future plans.
Turkey also maintains very close cooperation/coordination with non-ECAC neighbours such as Iran and Syria. With a very
positive initiative of the Iranian CAA, the Tehran ACC started to assign RVSM flight levels to aircraft that are compatible with RVSM, before transferring to Ankara FIR.
By means of three new ATS routes and FIR boundary entry/exit points between Turkey and Syria, which were valid from 13 May 2004,
optimum flight routes were established for a better interface.
The complete re-opening of Iraqi Airspace is expected to improve capacity and enhance the ATM interface within the region.
Operational Letters of Agreement (LoAs) have been signed between İstanbul and Ankara ACCs and their neighbouring ACCs by using the common EUROCONTROL format. The recent restructuring of airspace was also taken into consideration in these LoAs.
