Regulation (EU) 2023/1772
(a) When CPDLC is transferred, the transfer of voice communication and
CPDLC shall commence concurrently.
(b) When an aircraft is transferred from an air traffic control unit where
CPDLC is available to an air traffic control unit where CPDLC is not
available, the termination of CPDLC shall commence concurrently with the
transfer of voice communication.
(c) The air traffic controller shall be informed when attempting a transfer
of CPDLC resulting in a change in data authority if there are data link
messages for which a closure response has not been received. When the air
traffic controller decides to transfer the aircraft without receiving pilot
responses to the uplink message(s) outstanding, the air traffic controller
shall normally revert to voice communication to clarify any ambiguity
associated with the uplink message(s) outstanding.
