EUROCONTROL Specifications for harmonized Rules for OAT under IFR inside controlled Airspace of the ECAC Area (EUROAT)
25 September 2018
The implementation of the Single European Sky (SES) and future ATM arrangements and technology developed by the SES ATM Research programme (SESAR) are aimed at safe, efficient and effective airspace utilisation to satisfy the needs of civil and military airspace user.
Furthermore, SES intends to create pan-European airspace independent of national borders, to better facilitate predicted future demands regarding safety, capacity, efficiency and environmental improvements.
Existing worldwide security threats and lessons learned from multi-national military operations demonstrated the need for dependable and robust pan-European Operational Air Traffic (OAT) provisions and structures to effectively support military and other State aircraft aviation.
OAT regulatory scope
To appropriately facilitate OAT and its interface with General Air Traffic (GAT) within the SES environment, it is the intent of EUROCONTROL Member States to harmonise and standardise relevant national OAT rules at ECAC level and therefore, Member States required the Agency to develop respective specifications.
The EUROCONTROL Specifications for harmonised Rules for OAT-IFR inside controlled airspace of the ECAC area as detailed in this document are satisfying this requirement and enable the EUROCONTROL Member States to achieve the intended harmonisation, pending their individual national implementation.
Additionally, this specification is in line with the declaration of the EU Member States in the SES Framework Regulation (EC 549/2004) and will support them to enhance civil-military coordination and the facilitation of cooperation between their armed forces in ATM matters.
National Implementation of the rules and procedures specified in this document will ensure OAT-IFR harmonisation/standardisation within the controlled airspace of all States that have chosen to implement the EUROAT.
However, military and other state aircraft will continue to require a valid diplomatic clearance to cross national borders.
