Estimated Off-Block Time (EOBT) update service for A-CDM departures

23 January 2018

Aircraft operators (AOs) can now delegate the filing of delay (DLA) messages for departures from designated Collaborative Decision Making (CDM) airports to the Network Manager (NM). NM will then automatically file the message on behalf of the AO using the Target Off-Block Time (TOBT) values in the Departure Planning Information (DPI) messages received. The DLA will be triggered when there is a discrepancy between the TOBT and the Estimated Off-Block Time (EOBT), at which point the EOBT will be automatically updated.


This service aims at streamlining tactical flight operations for the partners involved, using A-CDM data.

More information about the service and why you should opt for it is available in our leaflet. The leaflet also contains a list with the current A-CDM airports at which the service can be activated.
