Civil Aviation Operations Over or Close to Conflict Zones

The safety and security of an aircraft operation to or through a particular geographical area or location is entirely the responsibility of the Aircraft Operator; the Isle of Man Aircraft Registry does not specifically prohibit or allow such operations.


Under the Convention on International Civil Aviation (Chicago Convention), individual States maintain sovereign authority over their airspace. This authority carries with it the responsibility to issue risk advisories regarding any threats to the safety of civilian aircraft operating in their airspace.


States also have authority to close their own airspace where certain safety threats may warrant that action.


Any decision to undertake the operation should be very carefully considered given the risk and potentially adverse consequences involved. Therefore, prior to operating within or close to conflict zones, we strongly recommend that the operator completes a thorough safety and security assessment, taking into account global airspace risks communicated by States and/or third parties, including NOTAMs and AICs and any other official publication, in determining whether to undertake the operation. Furthermore, we strongly recommend that the Accountable Manager discusses the planned operation with the aircraft insurers to obtain their consent.


It is strongly recommended that the following tools are utilised by Aircraft Operators:

  • ICAO Conflict Zone Information Repository. The purpose of this site is the compilation of a centralized and recognized location certain information promulgated by States regarding risks to civil aircraft arising from conflict zones;
  • EASA Conflict Zone Alerting System. This system complements existing national infrastructure mechanisms when they exist, by adding, when possible, a European level common risk picture and corresponding recommendations. This is supported by a user friendly Conflict Zones Map. Users may also subscribe to regular EASA Conflict Zone Information Bulletins;
  • FAA Prohibitions, Restrictions and Notices. The country specific information provided as a public service may also be subscribed to;
  • All UK NOTAMs relating to conflict zone issues will be made available on the UK AIS Website. A list of current Airspace warnings is also available in the en-route section of the UK AIP at ENR 1.1 Section 1.4. It is possible that other States’ advice may differ from that provided by the UK.

UK NOTAMs concerning conflict zones represent the best advice available from UK Government sources in support of airline risk assessments.
