Civil-military cooperation in aviation


We are a civil-military organisation providing a unique platform for military and civil-military cooperation in aviation. We apply our technical knowhow and expertise to enhance airspace capacity, flight efficiency, military mission effectiveness and civil-military interoperability at reduced cost in a secure Single pan-European Sky.

Our objective is to support our Member States and cooperate with European and international organisations to improve network performance by balancing the needs between civil aviation and national security and defence.


One key priority for us is flexible use of airspace (FUA) and airspace management (ASM) in the spirit of civil-military collaborative decision-making (CDM), to allow airspace users to efficiently share Europe’s airspace at all times. In close cooperation with the EUROCONTROL Network Manager (NM) we develop and maintain concrete solutions to improve ASM processes at strategic, pre‐tactical and tactical levels, including our local and sub-regional airspace management support system (LARA), civil-military aviation coordination tool (CIMACT) and pan-European repository of information supporting civil- military key performance indications (PRISMIL). The Military Liaison Officer (MILO) function in the NM Operations Centre supports the CDM processes in FUA and ASM. Currently we work on enhancing and harmonising FUA, moving from a national towards the network perspective, while using available system support, but also on advanced FUA in SESAR automating many functions and processes.

Aviation modernisation is underway to introduce new technologies and higher levels of automation and connectivity. Civil-military communication, navigation and surveillance (CNS) infrastructure and interoperability are fundamental to addressing today’s capacity and performance challenges. We offer specific civil-military CNS technical expertise to enhance civil-military CNS interoperability and to integrate military requirements in all CNS developments including rulemaking, research and deployment. We develop technical solutions to optimise airborne equipage and infrastructure to seamlessly accommodate military at reduced cost. Our efforts cover a wide range of CNS, spectrum and data processing domains where civil-military coordination is required. In particular, we progress technical work to address civil-military interoperability challenges in important CNS domains. This includes ground communications, deployment of data link services, performance based navigation, reutilisation of GNSS restricted signals for military aircraft, RVSM monitoring for State aircraft, impact of Mode S and ADS-B on military operators, military requirements related with aeronautical information management (AIM) and system wide information management (SWIM). This includes a dual use CNS concept and performance based certification (PBC)/performance equivalence for military aircraft. In addition, we cooperate with NM in the management of scarce resources, like transponder codes and radio frequencies.

Civil-military cooperation and coordination is part of the SESAR initiative and the European ATM Master Plan. Our research contributions follow the principles of interoperability, information sharing, collaborative decision-making, and performance equivalence. In cooperation with NM we developed the mission trajectory concept and, in particular, the dynamic mobile areas and the improved operational air traffic (OAT) flight plan in support of advanced flexible use of airspace (AFUA). We work to develop the SWIM green profile improving secure civil-military connectivity with civil data exchange systems, as well as CNS solutions optimising the reuse of existing military capabilities and reducing the need for exemptions. Our efforts contribute towards the development and integration of technologies and resources for a single operating environment fulfilling all performance criteria for military and civil users.

We define security baselines for today’s ATM environment and do our part in keeping the ATM systems secure from threats and vulnerabilities and contribute to civil aviation security, national security, defence and law enforcement. We are responsible for enhancing ATM security and provide civil-military coordination on all relevant ATM-security (airspace, aviation and related cyber/InfoSec) issues in close consultation with Member States, the International Civil Aviation Organisation (ICAO) and the European Civil Aviation Conference (ECAC) and, as required, the European Commission and the European Aviation Safety Agency (EASA). We coordinate with the North Atlantic Treaty Organisation (NATO) through an ATM Security Coordinating Group (NEASCOG), enhance international collaboration and providing ATM security implementation support and training to States, stakeholders and international organisations.

Enhanced coordination and cooperation at EU and international level is one of the key priorities for EUROCONTROL to improve the network performance. In this regard we support ICAO in the global implementation of civil-military cooperation in airspace management and flexible use of airspace, including contributions to the GANP and ASBUs to enhance global civil-military interoperability. We effectively cooperate with the North Atlantic Treaty Organisation (NATO) and the European Defence Agency (EDA) on military and civil-military matters in accordance with the established working arrangements. Individual support is also made available for States and stakeholders to implement key civil-military coordination initiatives to increase airspace capacity, flight efficiency and military mission effectiveness in Europe. We also contribute upon request to supporting the EU Single European Sky implementation and the SESAR deployment as well as the European Aviation Safety Agency (EASA) rulemaking and in cooperation with our military partners to analyse potential impacts on the military. The Civil-Military Interface Standing Committee (CMIC), the Military ATM Board (MAB) and other working groups, such as the NATO-EUROCONTROL ATM Security Coordinating Group (NEASCOG), the Military Harmonisation Group (MilHaG), the Civil-Military CNS Focus Group (CNS-FG) and the Military Engagement Plan for SESAR (MEPS) are platforms for Member State/stakeholder consultations.
