EUROCONTROL NM Operational Problem Reporting

eTOKAI will replace CCMS Web for post-event operational problem reporting from 01 May 2026

eTOKAI is recognised as an easy-to-use online tool already utilised by many Air Navigation Service Providers (ANSPs) for occurrence investigation, supporting safety management systems and partner collaboration.   

Users who wish to report post event operational problems via eTOKAI can request access via the contact us button. Select ‘’Post-event incident investigations’’ from the dropdown menu.  In ‘’Your question’’, insert: eTOKAI access request.

Where external users of the NM operational services encounter problems, a number of possible reporting methods are available, depending on the type of problem and the service concerned.

This procedure is divided into three parts:

  • Real Time Operational Problem Reporting The first part gives detailed instructions for external users of the NM operational services who encounter operational problems which require immediate action.
  • Post Event Operational Problem Reporting The second part provides reporting instructions for external users of the NM operational services in post event mode, where either an operational problem has occurred or apparent anomalous behaviour has been identified.
  • Technical Problem Reporting Part three indicates the actions required for external users of the NM operational services who encounter technical difficulties.
