EUROCONTROL Guidelines for Contingency Planning of Air Navigation Services

The States and Air Navigation Service Providers (ANSPs) responsible for providing air navigation services are primarily responsible in the event of failure and/or disruption of those services.  ANSPs and State authorities obligations concerning ANS Contingency Planning are set by the International Civil Aviation Organisation (ICAO) and the European Community (EC).

These guidelines, revised in 2009, are intended to assist ANSPs in developing sound contingency planning. 

The guidelines aim to provide information and processes to help States and ANSPs identify and decide on the contingency strategies and concept of operation best suited to meet their needs in certain circumstances.

The ‘Guidelines’ also subsume the information previously contained in the “EUROCONTROL Guidance for Design of Contingency Strategies” document. The information is intended to help ANSPs take decisions to mitigate a broad range of threats and hazards including natural disasters, security threats, software bugs, volcanic ashes and, most typically, pandemics.

The potential strategies described have been constructed on the best practices of a number of ECAC ANSPs and reflect a variety of approaches available to ANSPs in meeting their contingency needs.

The strategies include

  • co-located facilities
  • multi-use facilities
  • centralised facilities
  • ATS delegation
  • common/shared system solutions
  • hybrid models
