A-CDM validation with Eurocontrol is ongoing!
Arlanda is currently conducting an A-CDM validation together with Eurocontrol with the goal of connecting us live to NMOC.
The validation period is initially expected to last throughout 2026, depending on the outcome of the various stages.
Until completion of approved validation with Eurocontrol
Until we have completed an approved validation with Eurocontrol, you are kindly encouraged to:
- AO - Update EOBT in case of delays to reduce the risk of FLS after Off-block.
- GH - Update the TOBT if necessary in good time.
NOTE: There is no relationship between TOBT updates and CTOT until we are in the race against NMOC.
