8.8.3.1.7 Če je sporočilo o koordinaciji uspešno oddano hkrati s sporočilom za isti let iz predajne enote, na primer z revizijo ali preklicem koordinacije, se ne vrne niti potrditev niti operativni odgovor.
In the event that a CDN is transmitted effectively simultaneously with a message for the same flight from the transferring unit, e.g. a revision or an abrogation of co-ordination, neither an acknowledgement nor an operational reply shall be returned.
