Germany's BMV Issues AIC on Flight Prohibitions and Operational Recommendations for Conflict Zones

Germany's Federal Ministry of Transport (BMV) has published an Aeronautical Information Circular (AIC) setting out the framework for flight prohibitions and operational recommendations covering German civil aviation operators flying over or near conflict zones. The system traces back to the downing of Malaysian Airlines flight MH17 on 17 July 2014, after which the German Federal Aviation Office (LBA) began preparing threat and risk analyses for third countries to support the BMV. The BMV is the competent authority for issuing flight prohibitions under section 26a, subsection 1 of the German Aviation Act (LuftVG), while DFS Deutsche Flugsicherung GmbH publishes the relevant notices on the BMV's behalf.

The AIC defines three risk levels. Level 1, a medium abstract risk, triggers an advisory recommending operators factor potential risk into their own risk assessment and routing decisions. Level 2, a high abstract risk, brings a recommendation that operators not enter the affected airspace. Level 3, a concrete risk, results in a formal flight prohibition under section 26a LuftVG, accompanied by a general order (Allgemeinverfügung) published on the BMV website. Prohibitions and recommendations are issued only where ICAO Annex 17 security standards and other risk-mitigation measures are found insufficiently applied in the third country concerned, based on evaluations the LBA conducts regularly and as circumstances require.

Risk notifications first appear as a Notice to Air Missions (NOTAM) for a maximum of three months under ICAO Annex 15, section 6.3.2.2; if longer validity is needed, the NOTAM is transferred into the AIC and cancelled, and DFS extends the reference NOTAM every three months. A current NOTAM always supersedes the corresponding AIC entry. Conflict zone boundaries may be specified laterally by coordinates, airways or waypoints, and vertically by flight level, with the type of threat, such as terrorist attacks or anti-aviation weaponry, stated in the notification. The pilot in command is authorised to deviate from prohibitions and recommendations in emergencies, and enquiries can be directed to conflictzones@lba.de.

This is a case of a national aviation authority formalising, in writing, a risk-tiering process that many states run informally after a catastrophic event exposes a gap in conflict-zone threat assessment. The tiered structure — advisory, avoidance recommendation, formal prohibition — mirrors how airspace risk is generally handled internationally: operators are expected to weigh national notices alongside their own intelligence, and the legal force only escalates once a state judges that ICAO Annex 17 security standards are not being adequately met on the ground.

The mechanics matter for operators planning routes near unstable regions: a Level 3 prohibition carries statutory force under LuftVG, while Levels 1 and 2 remain advisory judgment calls left to the operator's own risk assessment. The three-month NOTAM cycle, with automatic DFS extension and NOTAM-over-AIC precedence, means the binding status of any given airspace can shift on a short, recurring clock rather than staying fixed at publication.

What happens next depends on how the LBA's regular and circumstance-driven evaluations are applied to specific third countries, since the AIC itself sets the process rather than naming which airspaces currently sit at which level. Operators with routes touching flagged regions would need to track the reference NOTAM's quarterly renewal and any transfer of that NOTAM into the AIC to know whether a recommendation has hardened into a prohibition.
